Description

The present invention relates to a cosmetic material and a method for manufacturing the cosmetic material.

Conventionally, decorative materials have been used for the surfaces of tables, counters, walls, floors, etc., by impregnating a porous substrate such as titanium paper with an uncured liquid of melamine resin and curing the impregnated resin with a heat press. If necessary, such decorative materials may be further laminated with phenol core paper, etc. Such decorative materials impregnated and cured with melamine resin exhibit physical properties such as strength, hardness, and heat resistance.

Such decorative materials are required to have a design that gives off a sense of luxury, and a visual three-dimensional effect is imparted by forming an uneven surface.
As a decorative material having an uneven surface, there has been proposed a decorative material that is embossed using an embossing plate (a textured mirror plate) on which an uneven surface is formed (see, for example, Patent Documents 1 and 2).

However, when imparting a desired textured pattern to the surface of the decorative material described in Patent Documents 1 and 2, an embossing plate is required for each pattern, which is costly and difficult to manufacture. In addition, it is difficult to harmonize the textured shape with the underlying design of this decorative material, which makes it difficult to impart a high level of design.

On the other hand, Patent Document 3 proposes a decorative material with a surface irregularity that does not use an embossing plate.

JP 2015-193209 A JP 2017-87544 A International Publication No. 2016/148091

The decorative material of Patent Document 3 includes a paper base material, a release layer containing a cured product of an ionizing radiation curable resin provided on a part of the surface of the paper base material, and a surface layer containing a cured product of a melamine resin provided on the remaining part of the surface of the paper base material. The decorative board of Patent Document 3 is manufactured by a method including a step of providing a release layer on a part of the surface of the paper base material, a step of impregnating the paper base material with an uncured product of melamine resin and coating the release layer with the uncured product of melamine resin, and then heating to thermally cure the uncured product of melamine resin, and a step of peeling off the cured resin film coating the release layer. As a result, the decorative material of Patent Document 3 has an elevation difference between the area with the release layer and the area without the release layer, and a surface uneven shape is formed.
The decorative material of Patent Document 3 does not use an embossed plate, and therefore can solve the problems of Patent Documents 1 and 2. However, when the decorative material of Patent Document 3 is used in places where a high level of wear resistance is required, such as a table, there have been many cases where the design deteriorates over time.

As a result of intensive research, the inventors have found that the decorative material of Patent Document 3 has a reduced design quality because it is not possible to suppress wear of the decorative layer after wear of the release layer containing a cured product of an ionizing radiation curable resin and the surface layer containing a cured product of a melamine resin.
As a result of further intensive research, the present inventors have completed a decorative material that has a visual three-dimensional effect and can dramatically improve abrasion resistance.

The present invention aims to provide the following items [1] to [3].

1 and 2 are cross-sectional views showing an embodiment of a decorative material 100 of the present invention.
The decorative material 100 in Figures 1 and 2 has a first region R1 and a second region R2 in a plane (in the XY plane in the figures). The surface of the first region R1 is at a lower elevation than the surface of the second region R2. In addition, when the entire surface of the decorative material 100 in the plane is considered as a universal set, the first region R1 and the second region R2 are in a complementary relationship with each other in the decorative material 100 in Figures 1 and 2.
1 and 2 has a first hardened material layer 21 having a releasable surface on the substrate A (10) in a location corresponding to the first region R1. Also, the decorative material 100 in Fig. 1 and 2 has a second hardened material layer 22 on the substrate A (10) in a location corresponding to the second region R2. Also, in the decorative material 100 in Fig. 1 and 2, the first hardened material layer 21 and the second hardened material layer 22 are formed on the same side of the substrate A (10) (the positive side in the z-axis direction of the substrate A in the figures).
1 and 2, the decorative material 100 has a decorative layer 30 on the side opposite to the side of the substrate A (10) having the first hardened material layer 21 and the second hardened material layer 22 (the negative side in the z-axis direction of the substrate A in the figures). The decorative layer 30 in Fig. 1 and 2 has a first decorative layer 31 that is in tune with the first region R1 and a second decorative layer 32 that is in tune with the second region R2. As shown in Fig. 1 and 2, the first decorative layer 31 and the second decorative layer 32 are preferably in tune with the first region R1 and the second region R2, respectively, but may be non-in tune with them.
The decorative material 100 in FIG. 2 also has a base material B (50) and a reinforcing layer 60 on the surface of the decorative layer 30 opposite the base material A (10).
1 and 2, t1 indicates the thickness of the first hardened material layer 32, and t2 indicates the thickness of the second hardened material layer 22. In addition, in FIG.

In this specification, the term "plane" refers to a surface viewed vertically from the side of substrate A having the first hardened material layer and the second hardened material layer, when substrate A of the decorative material is used as a reference, and means the xy plane in Figures 1 and 2.
In addition, in this specification, "altitude" refers to the thickness direction of the decorative material, and refers to the z direction in Figures 1 and 2. Note that a specific location (specific surface, specific position, etc.) having a high (or low) altitude means that the value of the z coordinate in the thickness direction of the specific location is relatively large (or small). In Figure 1, the higher the specific location is in the figure, the higher the altitude, and the lower the specific location is in the figure, the lower the altitude.
In this specification, the term "synchronization" includes, of course, a state in which the two target patterns are completely matched and overlapped in shape and position when the decorative material is viewed in a plan view, but is not strictly limited to this state, and is a concept that allows for misalignment of shape and position as long as there is no discomfort in the external design and no impairment in quality. Examples of the two target patterns include a combination of the first decorative layer 31 and the first region R1, and a combination of the second decorative layer 31 and the second region R2.

In this specification, the term "curable resin" refers to a cured product obtained by curing an uncured curable resin. Similarly, the term "thermosetting resin" refers to a cured product obtained by curing an uncured thermosetting resin, and the term "ionizing radiation curable resin" refers to a cured product obtained by curing an uncured ionizing radiation curable resin.
In this specification, the terms "curable resin composition,""thermosetting resin composition," and "ionizing radiation curable resin composition" mean that the composition is uncured, unless otherwise specified.

<Substrate A>
The substrate A is a resin-impregnated paper having optical transparency, and is located between the first cured product layer and the second cured product layer and between the decorative layer and the decorative layer.
In the decorative material of the present invention, even if the first cured product layer and the second cured product layer are worn, the decorative layer is protected by the base material A, so that the wear resistance can be dramatically improved.

The base material A only needs to have light transmittance to such an extent that the decorative layer can be visually recognized.
The substrate A preferably has a total light transmittance according to JIS K7361-1:1997 of 40% or more, and more preferably 50% or more.
Furthermore, the haze of the substrate A itself may generally vary depending on the location within the plane of the decorative material 100. The haze of the substrate A may be 10% or more and 96% or less. The lower limit of the haze of the substrate A is preferably 20% or more, and more preferably 30% or more. The upper limit of the haze of the substrate A is more preferably 90% or less, and more preferably 60% or less. In this specification, haze refers to the haze according to JIS K7136:2000.

The total light transmittance or haze of the substrate A may be the same or different within the plane of the substrate A. For example, the total light transmittance or haze of a portion of the substrate A having a first cured material layer and a portion of the substrate A having a second cured material layer may be the same or different.

In order to provide contrast between the first region R1, which has the first cured material layer, and the second region R2, which has the second cured material layer, and to enhance the design of the decorative material, it is preferable to set the total light transmittance or haze value to different values in the area of the substrate A having the first cured material layer and the area of the substrate A having the second cured material layer.

In addition, when the haze of the portion of the base material A having the first hardened material layer is defined as Hz1, and the haze of the portion of the base material A having the second hardened material layer is defined as Hz2, it is preferable to satisfy the relationship Hz2<Hz1. By adopting such a configuration, a contrast of glossiness can be imparted to the first region having the first hardened material layer and the second region having the second hardened material layer, thereby improving the design of the decorative material. In addition, by satisfying the relationship Hz2<Hz1, the first region is more likely to appear recessed, and the visual three-dimensional effect can be more easily enhanced. In particular, in the configuration satisfying the relationship Hz2<Hz1, by configuring the base material A to contain a coloring agent, a color tone is added to the glossiness, and the contrast between the two regions becomes clearer, making the pattern clearer and improving the design.
The value Hz1-Hz2 is preferably 1% or more and 30% or less, and more preferably 5% or more and 20% or less.

In order to provide a visual contrast between the first region R1 having the first cured material layer and the second region R2 having the second cured material layer and to enhance the design of the decorative material, it is preferable that the color tone of the first region R1 is more opaque than the color tone of the second region R2 when the decorative material 100 is observed from the side of the first cured material layer 21. More opaque means higher brightness. Specifically, when defined by the brightness of the Munsell color system, the difference (V1-V2) between the brightness V1 in the first region R1 and the brightness V2 in the second region R2 is preferably 2 or more, more preferably 4 or more.
In addition, the saturation of the first region R1 is preferably lower than that of the second region R2. In this case, the difference (C2-C1) between the saturation C1 in the first region R1 and the saturation C2 in the second region R2 is preferably 2 or more and 6 or less, and more preferably 2 or more and 4 or less.
That is, the relationship between the color tone of the first region R1 and the color tone of the second region R2 includes the following forms (1) to (3). In order to provide a visual contrast between the regions R1 and R2 and to enhance the design of the decorative material, form (1) or (2) is preferred, and form (2) is more preferred.
(1) V1>V2 and C1=C2
(2) V1>V2 and C1<C2
(3) V1>V2 and C1>C2
In order for the color tone of the first region R1 to be visually perceived as more cloudy than the color tone of the second region R2 when the decorative material 100 is observed from the side of the first hardened material layer 21, it is preferable to satisfy the following relationship (4), and it is more preferable to satisfy the following relationships (4) and (5). When the following relationship (4) is satisfied, the difference between the haze of the first region R1 of the laminate B and the haze of the second region R2 of the laminate B is preferably 1% or more and 30% or less, and more preferably 5% or more and 20% or less. The layer structure of the laminate B is described in the manufacturing method of the decorative material described below.
(4) Haze of the first region R1 of the laminate B>Haze of the second region R2 of the laminate B (5) Total light transmittance of the first region R1 of the laminate B≠Total light transmittance of the second region R2 of the laminate B

The substrate A (resin-impregnated paper having optical transparency) can be obtained, for example, by impregnating a base paper with a resin. In this case, the optical transparency of the substrate A can be increased and the haze can be reduced by bringing the refractive index of the fibers constituting the paper closer to that of the resin and by sufficiently filling the gaps between the fibers with the resin. That is, even if the base paper itself is opaque, a resin-impregnated paper (substrate A) having optical transparency can be obtained by sufficiently impregnating the paper with a resin having a similar refractive index. In addition, the optical transmittance and haze can be adjusted by controlling the amount of resin impregnated into the base paper. Furthermore, by providing areas with different amounts of resin impregnated within the plane of the base paper, areas with different optical transmittance and haze values can be provided within the plane of the substrate A.
The substrate A may be a laminate of resin-impregnated papers having optical transparency. A laminate of resin-impregnated papers having optical transparency can be obtained by impregnating a plurality of base papers in a stacked state with a resin.

In order to facilitate the color tone of the first region R1 being cloudy compared to the color tone of the second region R2, it is preferable to impregnate the paper with the curable resin composition from the side of the first cured material layer 21 in step A3 described later. As a result, in the inside of the paper, in the paper directly below the first cured material layer 21 corresponding to the first region R1, the resin impregnation is inhibited by the first cured material layer 21, and air is likely to remain between the constituent fibers of the paper. Then, due to the refractive index difference between such paper constituent fibers and air, the light incident on the first region R1 is scattered, and the first region R1 is more likely to be cloudy than the second region R2. In addition, in the paper directly below the first cured material layer 21 corresponding to the first region R1, the resin forming the first cured material layer and the fibers are contained, and further, a small amount of impregnated resin is contained, so that the refractive index difference between these three materials can also be a cause of clouding.
On the other hand, in the second region R2 (region where the first hardened material layer 21 is not formed), the impregnating resin fills the spaces between the fibers constituting the paper without being hindered. The difference in refractive index between the impregnating resin and the fibers constituting the paper is smaller than the difference in refractive index between air and the fibers constituting the paper. As a result, the amount of scattering of light incident on the second region R2 is smaller than that of the first region R1, and therefore the degree of cloudiness in the second region R2 is smaller than that of the first region R1.

The paper serving as the base of the substrate A preferably has a basis weight of 20 g/m ² or more and 100 g/m ² or less, more preferably 25 g/m ² or more and 80 g/m ² or less, and even more preferably 30 g/m ² or more and 60 g/m ² or less. When the substrate A is a laminate of resin-impregnated papers having optical transparency, each of the multiple base papers preferably has a basis weight within the above range.
By making the basis weight of the base paper 20 g/m2 or ^more , the impregnated resin can be easily bound by the paper fibers. Also, by making the basis weight of the base paper 100 g/m2 or ^less , the resin can be easily impregnated into the paper.
When multiple papers are used as the base and paper of the substrate A, the total basis weight of the multiple papers is preferably 200 g/m ² or less from the viewpoint of visibility of the decorative layer.

Examples of the base paper for the substrate A include papers made from cellulosic pulp, such as wood pulp fiber paper with a high α-cellulose content, Manila hemp valve fiber paper, linter paper, and cotton fiber paper. Non-cellulosic resin fibers such as vinylon and acrylic resin may be mixed into these papers as necessary. In addition, to ensure sufficient light transmission after resin impregnation, it is preferable that the base paper does not contain any opacifying pigments such as titanium white or carbon black, or that only small amounts are added.

The paper that serves as the base of substrate A may contain a colorant. In other words, substrate A may contain a colorant. By including a colorant in substrate A, the design of the cosmetic material can be further improved. In particular, as described above, in a configuration that satisfies the relationship Hz2<Hz1, it is preferable that substrate A contains a colorant.

Examples of colorants include inorganic pigments such as yellow lead, titanium yellow, red iron oxide, cadmium red, ultramarine blue, and cobalt blue, organic pigments such as quinacridone red, isoindolinone yellow, nickel-azo complexes, and phthalocyanine blue, and dyes.

The resin impregnated in the substrate A may be a thermoplastic resin or a curable resin, and from the viewpoint of abrasion resistance, a curable resin is preferred. In this specification, the "resin impregnated in the substrate A" and the "resin impregnated in the substrate B" may be referred to as the "resin impregnated in the substrate A" and the "resin impregnated in the substrate B".
The amount of the curable resin relative to the total amount of the impregnated resin in the substrate A is preferably 50% by mass or more, more preferably 70% by mass or more, even more preferably 90% by mass or more, and even more preferably 100% by mass.
Examples of the curable resin include thermosetting resins and ionizing radiation curable resins, with thermosetting resins being preferred from the viewpoint of ease of handling.

From the viewpoint of adhesion between the substrate A and the second cured material layer and from the viewpoint of manufacturing efficiency, the impregnating resin of the substrate A is preferably the same as the resin of the second cured material layer. Furthermore, when the substrate B described below is impregnated with a resin, from the viewpoint of manufacturing efficiency, the resin impregnated into the paper is preferably the same as the impregnating resin of the substrate B. When the first cured material layer is formed on the substrate A, a small amount of the resin component constituting the first cured material layer or a small amount of the resin component constituting the permeation prevention layer is impregnated into the substrate A. In other words, the impregnating resin of the substrate A contains a small amount of the resin component constituting the first cured material layer or a small amount of the resin component constituting the permeation prevention layer.

As a thermosetting resin, which is a suitable embodiment of the impregnating resin of the substrate A, from the viewpoint of further enhancing the texture of the decorative material and improving the mechanical strength of the decorative material, melamine resin, urea resin, melamine-urea resin, guanamine resin, diallyl phthalate resin, polyester resin, phenol resin, epoxy resin, aminoalkyd resin, silicon resin, polysiloxane resin, etc. are preferred, and among them, thermosetting resins such as melamine resin, urea resin, melamine-urea resin, guanamine resin, and sulfonamide resin are preferred. Furthermore, among thermosetting resins, melamine resin, melamine-urea resin, and phenol resin are preferred, and melamine resin is particularly preferred.

Means for impregnating paper with resin include a method of preparing a composition containing a resin (in the case of a curable resin, an uncured curable resin) and impregnating the base paper with the resin composition (for example, steps (A3) and (B5) described below).
Of the resin compositions impregnated into the paper, the thermosetting resin composition is heated at an appropriate time to be cured through a crosslinking reaction, a polymerization reaction, or the like, to become a cured thermosetting resin (for example, steps (A5) and (B7) described below).
In steps (A2) and (B2) described later, the resin constituting the first cured material layer is cured in the steps (A2) and (B2). The region of the base material A having the first cured material layer is less likely to be impregnated with the resin in steps (A3) and (B5) than the other regions of the base material A. For this reason, the portion of the base material A having the first cured material layer and the portion of the base material A having the second cured material layer have different degrees of impregnation with the resin, and the total light transmittance or haze value of the two portions can be easily made different.

The thickness of the substrate A is preferably 80 μm or more and 360 μm or less, and more preferably 80 μm or more and 200 μm or less.
By making the thickness of the base material A 80 μm or more, it is possible to easily improve the abrasion resistance. Also, by making the thickness of the base material A 360 μm or less, it is possible to easily ensure the visibility of the decorative layer.

<Decorative layer>
The decorative material of the present invention has a decorative layer on at least a part of the side of the substrate A opposite to the side having the first cured product layer and the second cured product layer.
Since the decorative material of the present invention has the decorative layer at the above-mentioned position, the decorative layer is less susceptible to wear, and the wear resistance of the decorative material can be dramatically improved.

The decorative layer can be formed, for example, by printing with a decorative layer ink containing a colorant and a binder resin. There are no particular limitations on the pattern of the decorative layer.

The decorative layer preferably has at least one of a first decorative layer formed on at least a portion of the area corresponding to the first region and a second decorative layer formed on at least a portion of the area corresponding to the second region, and more preferably has both. The first decorative layer is preferably formed in accordance with the first region, and the second decorative layer is preferably formed in accordance with the second region.
The first decorative layer and the second decorative layer will be described in detail later.

Examples of the embodiment of the decorative layer are shown below in A to E.
A) A configuration in which the first decorative layer is synchronized in all first regions.
(a) A configuration in which the first decorative layer is present in all of the first regions, but the first regions and the first decorative layer are not synchronized, and the printing is misaligned.
(c) A configuration in which, among a plurality of first regions, some of the first regions have a first decorative layer, while other first regions do not have a first decorative layer.
(e) A configuration in which the second decorative layer is synchronized in all second regions.
E) A configuration in which the second decorative layer is present in all second regions, but the second regions and the second decorative layer are not synchronized, resulting in misaligned printing.
(c) A configuration in which, among a plurality of second regions, some of the second regions have a second decorative layer, while other second regions do not have a second decorative layer.
(g) A configuration having only a first decorative layer and not a second decorative layer.
(k) A configuration having only a second decorative layer.
I) A structure having a first decorative layer and a second decorative layer.

<Area>
The decorative material of the present invention has, within a plane, a first region R1 and a second region R2.
In addition, in the decorative material of the present invention, the elevation of the surface of the first region is lower than the elevation of the surface of the second region, so that the first region is visually perceived as being recessed compared to the second region, thereby imparting a three-dimensional effect.
The elevation of the surface of the first region can be adjusted by the total thickness of the layers formed on the first region of the substrate A. The elevation of the surface of the second region can be adjusted by the total thickness of the layers formed on the second region of the substrate A.

When the area of the first region R1 of the decorative material is defined as S1 and the area of the second region is defined as S2, S2/S1 is preferably 0.1 or more and 20 or less, and more preferably 0.5 or more and 10 or less.
By setting S2/S1 to 0.1 or more, it becomes easier to impregnate the paper that is the base of the substrate A with resin in post-processing (for example, steps A3 and B5 described below). Also, by setting S2/S1 to 20 or less, the balance between the proportion of areas that are visible as recessed and areas that are visible as raised can be set in an appropriate range, making it easier to improve the design.

First Zone
The first region is an area that is visually perceived as being recessed compared to the second region.
The first region has a first cured material layer having a releasable surface on a substrate A. From the viewpoint of easily increasing the elevation difference between the surface of the first region and the surface of the second region, a permeation prevention layer, which will be described later, may be provided between the substrate A and the first cured material layer.

It is preferable that the surface of the first region is roughened. By roughening the surface of the first region, the first region is more likely to appear recessed, which makes it easier to achieve a better three-dimensional effect.

--First hardened layer--
The first cured product layer has a surface with releasability.
Since the first cured material layer has a releasable surface, the second cured material layer on the first cured material layer is almost entirely peeled off. It is preferable that the second cured material layer on the first cured material layer is completely peeled off from the viewpoint of improving the three-dimensional effect due to the surface unevenness, but there are many cases where the second cured material layer cannot be completely peeled off from the first cured material layer. Therefore, a small amount of the second cured material layer may remain on the first cured material layer as long as it does not impair the effects of the present invention.

The first cured product layer is a layer formed from a curable resin, more specifically, a layer formed from a cured product of an uncured curable resin composition.
As the curable resin, from the viewpoint of obtaining a design with a higher texture and more excellent surface properties, a thermosetting resin or an ionizing radiation curable resin is preferably used, and from the viewpoint of abrasion resistance, an ionizing radiation curable resin is more preferable. That is, the first cured product layer preferably contains an ionizing radiation curable resin.

The first cured product layer may contain a thermoplastic resin, but preferably contains a curable resin as a main component.
Based on the total amount of resin in the first cured material layer, the curable resin is preferably 50% by mass or more, more preferably 70% by mass or more, even more preferably 90% by mass or more, and even more preferably 100% by mass.

Thermosetting resins for the first cured material layer include, for example, those exemplified as thermosetting resins that can be impregnated into the substrate A.

The ionizing radiation curable resin is a resin that is crosslinked and cured by irradiation with ionizing radiation, and has an ionizing radiation curable functional group. Here, the ionizing radiation curable functional group is a group that is crosslinked and cured by irradiation with ionizing radiation, and preferred examples include functional groups having an ethylenic double bond such as (meth)acryloyl group, vinyl group, and allyl group. In addition, the ionizing radiation means electromagnetic waves or charged particle beams that have an energy quantum capable of polymerizing or crosslinking molecules, and generally includes ultraviolet rays (UV) or electron beams (EB), but also includes electromagnetic waves such as X-rays and gamma rays, charged particle beams such as alpha rays, and ion beams.
Specifically, the ionizing radiation curable resin can be appropriately selected from polymerizable monomers and polymerizable oligomers that have been conventionally used as ionizing radiation curable resins.

As the polymerizable monomer, a (meth)acrylate monomer having a radically polymerizable unsaturated group in the molecule is preferable, and among them, a polyfunctional (meth)acrylate monomer is preferable. Here, "(meth)acrylate" means "acrylate or methacrylate".
Examples of polyfunctional (meth)acrylate monomers include (meth)acrylate monomers having two or more ionizing radiation-curable functional groups in the molecule and having at least a (meth)acryloyl group as the functional group. From the viewpoint of obtaining design properties with a higher texture and better surface properties, acrylate monomers having an acryloyl group are preferred.

The first hardened material layer preferably contains a release agent. By containing a release agent, even if another resin is laminated on the surface of the first hardened material layer, it can be peeled off, while the other resin adheres to the second region and is not peeled off, making it easier to impart an elevation difference between the surface of the first region and the surface of the second region (see steps (A7) and (B9) described below).

Examples of the release agent include fluorine-based release agents and silicone-based release agents. From the viewpoint of obtaining a design with a higher quality texture, silicone-based release agents are preferred.

When the content of the release agent is within the above range, the effect of adding the release agent can be efficiently obtained.

The first cured material layer preferably contains a filler such as an inorganic filler or an organic filler, and more preferably an inorganic filler from the viewpoint of abrasion resistance. When the first cured material layer contains a filler, the reflected light of the first region is diffused, making the first region more likely to appear recessed, and making it easier to improve the three-dimensional effect of the decorative material.
Examples of the inorganic filler include particles made of inorganic materials such as oxides such as aluminum oxide, magnesium oxide, silica, calcium oxide, titanium oxide, zinc oxide, and zirconia oxide, hydroxides such as aluminum hydroxide, magnesium hydroxide, and calcium hydroxide, carbonates such as magnesium carbonate and calcium carbonate, sulfates such as calcium sulfate and barium sulfate, and silicates such as magnesium silicate, aluminum silicate, calcium silicate, and aluminosilicate. Among these, oxides such as aluminum oxide, magnesium oxide, silica, calcium oxide, titanium oxide, and zinc oxide are preferred, and silica is particularly preferred.
Organic fillers include particles of acrylic, styrene, silicone, and the like.
The first cured product layer preferably does not contain any luster filler such as pearl pigments, metal particles, or metal flakes.

When the amount of the filler is within the above range, the effect of adding the filler can be efficiently obtained.

t1 and t2, as well as t0 (the thickness of the permeation prevention layer) described below, are preferably calculated as the average value of the thicknesses at 20 locations. The thickness can be calculated, for example, from a cross-sectional photograph of the decorative material. Note that it is preferable to select the 20 locations for calculating the average value so as not to bias the locations.

The first cured material layer can be formed, for example, by applying a first cured material layer ink containing the components that make up the first cured material layer to a part of the substrate A, drying it, and curing it. The area where the first cured material layer is formed on the substrate A becomes the first region R1.

- Penetration prevention layer -
The permeation prevention layer is optionally disposed between the substrate A and the first cured product layer.
By having a permeation prevention layer between the substrate A and the first cured material layer, the composition constituting the first cured material layer is prevented from permeating into the substrate A side, ensuring the thickness of the first cured material layer, and thus making it easier to increase the thickness of the second cured material layer and to improve the abrasion resistance of the decorative material.

The permeation prevention layer is preferably formed on a part of the substrate A, rather than on the entire substrate A. By forming the permeation prevention layer on a part of the substrate A, rather than on the entire substrate A, it is possible to easily impregnate the paper, which is the base of the substrate A, with the resin.
The permeation prevention layer is preferably formed in accordance with the first region.

Thermosetting resins for the permeation prevention layer can be the same as those exemplified as thermosetting resins that can be impregnated into substrate A.

The ionizing radiation curable resin of the permeation prevention layer may be the same as the ionizing radiation curable resin exemplified for the first cured material layer. From the viewpoint of easily suppressing the permeation of the composition forming the permeation prevention layer into the substrate, the ionizing radiation curable resin of the permeation prevention layer is preferably a polymerizable oligomer having two or more ionizing radiation curable functional groups in the molecule.

From the viewpoint of facilitating the formation of the first cured product layer, it is preferable that the permeation prevention layer does not substantially contain a release agent. "Substantially does not contain a release agent" means that the content of the release agent is less than 0.1% by mass of the total solid content of the permeation prevention layer, preferably 0.01% by mass or less, and more preferably 0% by mass (no release agent is contained).

It is preferable that the permeation prevention layer contains substantially no filler. "Contains substantially no filler" means that the filler content is less than 0.1% by mass of the total solid content of the permeation prevention layer, preferably 0.01% by mass or less, and more preferably 0% by mass (no filler).

The thickness t0 of the permeation prevention layer is preferably 0.1 μm or more and 10.0 μm or less, and more preferably 0.5 μm or more and 5.0 μm or less.
By setting t0 to 0.1 μm or more, it is possible to easily suppress the uncured curable resin composition contained in the ink for the first cured layer from permeating into the substrate side. Also, by setting t0 to 10.0 μm or less, it is possible to stably form a permeation prevention layer without affecting other regions.

When the thickness of the permeation preventing layer is defined as t0, the thickness of the first cured material layer as t1, and the thickness of the second cured material layer as t2, it is preferable to satisfy the relationship t0 + t1 < t2. By satisfying such a relationship, it is possible to easily impart a three-dimensional effect to the decorative material.
t2-(t0+t1) is preferably 1.0 μm or more and 45.0 μm or less, more preferably 2.0 μm or more and 35.0 μm or less, and even more preferably 3.0 μm or more and 30.0 μm or less.
By setting t2-(t0+t1) to 1.0 μm or more, it is possible to easily achieve a good three-dimensional effect, and by setting t2-(t0+t1) to 45.0 μm or less, it is possible to easily and stably manufacture the first region and the second region.

The permeation prevention layer can be formed, for example, by applying a permeation prevention layer ink containing the components that make up the permeation prevention layer to a portion of the substrate A, drying, and curing the ink.

-First decorative layer-
The decorative material of the present invention preferably has a first decorative layer in at least a part of the area corresponding to the first region on the side opposite to the side having the first cured material layer and the second cured material layer of the substrate A. In addition, the first decorative layer is preferably formed in accordance with the first region.

The first decorative layer 31 may be formed in any desired pattern within the first region, depending on the design that is desired to be imparted to the entire decorative material.
For example, when the design to be applied to the entire decorative material is a wood pattern, the first decorative layer 31 is preferably formed with one or more patterns selected from vessels, spring wood, and knots, which are parts that form recesses in the wood board. In other words, the first region is preferably formed with one or more patterns selected from vessels, spring wood, and knots of wood. Vessels are cylindrical cells that serve as a passage for moisture, and when the wood is sawn into a board, the arrangement of tiny vessels forms groove-like recesses along the arrangement and appears to the human eye to have a dark pattern. Spring wood is a part that is formed from spring to summer with a wide grain width and a light color. The part that is formed from summer to autumn with a narrow grain width is called autumn wood, and the spring wood and autumn wood are alternately repeated to form the annual rings of wood. Knots are traces of branches that have been incorporated into the trunk, have a circular or elliptical shape, and have a darker color than the surrounding tissue.
In addition, when the design to be imparted to the entire decorative material is a stone pattern such as travertine, it is preferable that the first decorative layer 31 has a recessed pattern. In other words, it is preferable that the first region is formed with a stone recessed pattern.

By setting Ra1 to 1.0 μm or more, the first region can be made to look concave. Also, by setting Ra1 to 5.0 μm or less, the first region can be prevented from looking whitish, and the design can be easily improved.

Ra1 can be adjusted, for example, by the surface shape of the substrate A, or the particle size and amount of inorganic filler added in the first cured material layer.

That is, the second cured material layer preferably contains a thermosetting resin. By using a thermosetting resin, a design with a higher texture can be obtained, and the adhesion to the substrate A is improved, and superior mechanical strength can be obtained.

The paper substrate and the fiber substrate can be impregnated with a curable resin to easily increase adhesion with the substrate A and the reinforcing layer described later.
Furthermore, if a material having a concealing property is used as the base material B, it is possible to prevent the color of the reinforcing layer, which will be described later, from showing through.
Furthermore, by using a paper substrate or fiber substrate impregnated with a curable resin as substrate B, improvements in the mechanical strength and scratch resistance of the decorative material can be expected.

Among them, melamine resin, urea resin, melamine-urea resin, guanamine resin and sulfonamide resin are preferred, more preferably melamine resin, melamine-urea resin and phenolic resin, and even more preferably phenolic resin and melamine resin.

As a means for impregnating the base material B with a thermosetting resin, a method may be used in which an uncured thermosetting resin composition is prepared and the base material is impregnated with the resin composition (for example, steps (A3) and (B5) described below).
The impregnated composition is heated at an appropriate time to be cured by a crosslinking reaction, a polymerization reaction or the like, to become a cured thermosetting resin (for example, steps (A5) and (B7) described below).

The impregnating resin of the substrate B may contain a thermoplastic resin, but preferably contains a curable resin as the main component.

By setting the total light transmittance of the substrate B within this range, the substrate B acts as a base and can improve the visibility of the decorative layer. In addition, by setting the total light transmittance of the substrate B within this range, the concealing properties of the substrate B are improved, making it easier to prevent the color of the reinforcing layer, described below, from showing through.

<Reinforcing layer>
For the purpose of improving mechanical properties, the decorative material may have a reinforcing layer on the surface of the decorative layer opposite the substrate A. When the decorative material has substrate B, the reinforcing layer is preferably disposed on the surface of substrate B opposite the decorative layer.

The reinforcing layer may be a sheet impregnated with a thermosetting resin.
The types of fiber substrate and paper substrate used in the thermosetting resin-impregnated sheet are not particularly limited as long as they are the same as those exemplified as the fiber substrate and paper substrate of the substrate B, and the basis weight is preferably 100 g/m ² or more and 300 g/m ² or less, more preferably 150 g/m ² or more and 250 g/m ² or less.

The adhesive may be used alone, or two or more of these may be laminated together to form a composite substrate.

There are no particular limitations on the method of laminating the substrate and various adherends, and it is possible to employ a method in which, for example, a sheet is attached to the adherend with an adhesive. The adhesive may be appropriately selected from known adhesives depending on the type of adherend, etc. Examples include polyvinyl acetate, polyvinyl chloride, vinyl chloride-vinyl acetate copolymer, ethylene-acrylic acid copolymer, ionomer, etc., as well as butadiene-acrylonitrile rubber, neoprene rubber, natural rubber, etc.

<Applications>
The decorative material of the present invention is used, for example, for tops of various counters and desks, furniture, cabinets for kitchen products, building materials for homes such as doors, etc. Among these, members including horizontal surfaces such as tops used for counters and desks are preferred in that they are easily able to exert the effects of the decorative plate of the present invention because they require a visual three-dimensional effect and abrasion resistance due to rubbing against various items such as clothing, cleaning supplies, and watches.

[Method of manufacturing cosmetic material]
The decorative material of the present invention can be produced, for example, by a process including the following (A1) to (A7).
(A1) A step of preparing paper that will serve as the base of the substrate A.
(A2) A step of forming a laminate A having a first cured material layer having a releasable surface on at least a portion of one side of a paper sheet, and a decorative layer on the other side.
(A3) A step of impregnating the laminate A with a curable resin composition, thereby impregnating paper with the curable resin composition to obtain a substrate A which is a resin-impregnated paper having optical transparency, and forming an uncured curable resin composition layer on the entire surface of the side of the laminate A having the first cured material layer to obtain a laminate B.
(A4) A step of obtaining a laminate C by disposing a release film on the uncured curable resin composition layer side of the laminate B.
(A5) A step of hot pressing both sides of the laminate C between mirror plates to form a second cured material layer by curing the uncured curable resin composition layer.
(A6) A step of removing the laminate C from between the mirror plates.
(A7) A process for forming a first region by removing the second cured material layer on the first cured material layer of the second cured material layer together with the release film when peeling and removing the release film from the laminate C, and forming a second region in which the second cured material layer formed in an area not having a first region forming layer remains.

Although not shown, when removing the second hardened material layer 22 directly above the first hardened material layer 21 in the first region R1, only the second hardened material layer 22 near the surface of the first hardened material layer 21 may be left behind so that the surface becomes a rough thin film. By doing so, the surface of the concave portion of the first region R1 becomes rough and has a lower gloss than the surface of the surrounding second region, thereby emphasizing the three-dimensional effect formed by both regions R1 and R2.

Step (A1) is the step of preparing paper that will serve as the base for substrate A.

Step (A2) is a step of forming a laminate A (71) having a first hardened material layer 21 having a releasable surface on at least a portion of one side of the paper 10a and a decorative layer 30 on the other side (Figure 3).
Either the first hardened material layer 21 or the decorative layer 30 may be formed first.
The area where the first cured material layer 21 is formed becomes the first region R1 of the decorative material. It is preferable that the curable resin composition used to form the first cured material layer is cured at this stage.

When the decorative material has a substrate B, in step (A2), it is preferable to place substrate B on the surface of the decorative layer opposite substrate A. In other words, when the decorative material has substrate B, it is preferable that the laminate A1 includes substrate B.

If the decorative material 100 has a permeation prevention layer 41, it is preferable to have a step of forming the permeation prevention layer between steps (A1) and (A2). If the ink for forming the permeation prevention layer contains a curable resin composition, it is preferable for it to be cured at this stage.

In step (A3), laminate A is impregnated with a curable resin composition to impregnate the paper with the curable resin composition, thereby obtaining substrate A (10) which is a resin-impregnated paper having optical transparency, and also forming an uncured curable resin composition layer (22a) on the entire surface of the side of laminate A that has the first cured material layer, thereby obtaining laminate B (72) (Figure 4).

In step (A3), it is preferable to dry the curable resin composition contained in laminate B (72).

Step (A4) is a step of obtaining a laminate C (73) by disposing a release film 80 on the uncured curable resin composition layer 22a side of the laminate B (Figure 5).

The release film 80 has a role of removing the second cured material layer on the first cured material layer having a releasable surface from the second cured material layer obtained by curing the uncured curable resin composition layer 22a in steps (A7) and (B9) described later. In other words, when the adhesive strength between the release film and the second cured material layer is x1, and the adhesive strength between the second cured material layer and the layer located on the substrate A side of the cured material layer (the first cured material layer in the first region, and the substrate A in the second region) is x2, the material of the release film 80 is not particularly limited as long as it satisfies the relationship of x1>x2 in the first region and x1<x2 in the second region.

The release film 80 may be a single layer of a sheet of various resins such as polyester resins such as polyethylene terephthalate and polybutylene terephthalate; polyolefin resins such as polyethylene and polypropylene; and acrylic resins; or a resin layer formed on the resin sheet.

When the decorative material has a reinforcing layer, in step (A4), it is preferable to place the reinforcing layer on the surface of the decorative layer opposite the substrate A. In other words, when the decorative material has a reinforcing layer, it is preferable that the laminate C includes the reinforcing layer.

The step (A5) is a step of hot pressing the laminate C (73) with both sides of the laminate C (73) sandwiched between mirror plates to form a second cured material layer 22 by curing the uncured curable resin composition layer 22a.
During the step (A5), the curable resin composition impregnated in the substrate A and the substrate B can also be cured.

The conditions for the heat press can be adjusted appropriately depending on the type of thermosetting resin used, and there are no particular restrictions, but typically the temperature is between 100°C and 200°C, the pressure is between 0.1 MPa and 9.8 MPa, and the time is between 10 seconds and 120 minutes.

Step (A6) is a step of removing the laminate C from between the mirror plates.
Step (A7) is a step in which, when the release film is peeled off and removed from the laminate C, the second cured material layer on the first cured material layer of the second cured material layer is removed together with the release film to form a first region, and a second region is formed in which the second cured material layer formed in the area not having the first region forming layer remains ( FIG. 1 ).
In step (A7), the second cured material layer on the first cured material layer is removed while the second cured material layer remains on the second region, so that after step (A7), the surface of the first region has a lower elevation than the surface of the second region.

The decorative material of the present invention can be produced, for example, by a process including the following (B1) to (B9).
(B1) A step of preparing paper that will serve as the base for the substrate A.
(B2) A step of obtaining a laminate D by forming a first cured material layer having a releasable surface on at least a portion of one side of the paper.

(B4) A step of laminating the surface of the laminate D opposite the first cured material layer and the surface of the laminate E on the decorative layer side to obtain a laminate F.
(B5) A step of impregnating the laminate F with a curable resin composition to impregnate paper with the curable resin composition, thereby obtaining a substrate A which is a resin-impregnated paper having optical transparency, and forming an uncured curable resin composition layer on the entire surface of the side of the laminate F having the first cured material layer, thereby obtaining a laminate G.
(B6) A step of obtaining a laminate H by disposing a release film on the uncured curable resin composition layer side of the laminate G.
(B7) A step of hot pressing both sides of the laminate H between mirror plates to form a second cured material layer by curing the uncured curable resin composition layer.
(B8) A step of removing the laminate H from between the mirror plates.
(B9) A process for forming a first region by removing the second cured material layer on the first cured material layer of the second cured material layer together with the release film when peeling and removing the release film from the laminate H, and forming a second region in which the second cured material layer formed in an area not having a first region forming layer remains.

Step (B1) is the step of preparing the paper that will serve as the base for substrate A.

Step (B2) is a step of obtaining a laminate D by forming a first cured product layer having a releasable surface on at least a part of one side of paper.
Step (B3) is a step of forming a decorative layer on at least a part of one surface of the base material B to obtain a laminate E.

Either step (B2) or step (B3) may be carried out first.
The area where the first cured material layer 21 is formed in step (B2) becomes the first region R1 of the decorative material. It is preferable that the curable resin composition used to form the first cured material layer is cured at this stage.

If the decorative material 100 has a permeation prevention layer 41, it is preferable to have a step of forming the permeation prevention layer between steps (B1) and (B2). If the ink for forming the permeation prevention layer contains a curable resin composition, it is preferable for it to be cured at this stage.

Step (B4) is a step of obtaining laminate F (76) by laminating the surface of laminate D (74) opposite the first hardened material layer 21 with the surface of laminate E (75) facing the decorative layer 30 (Figure 6).

In step (B5), laminate F is impregnated with a curable resin composition to impregnate the paper with the curable resin composition, thereby obtaining substrate A (10) which is a resin-impregnated paper having optical transparency, and also forming an uncured curable resin composition layer (22a) on the entire surface of the side of laminate F having the first cured material layer to obtain laminate G (77) (Figure 7).

When the substrate B is a paper substrate or a fiber substrate, the substrate B can also be impregnated with the curable resin composition in step (B5).

Step (B6) is a step of obtaining a laminate H (78) by disposing a release film 80 on the uncured curable resin composition layer 22a side of the laminate G (Figure 8).

The release film 80 in step (B6) may be the same as the release film 80 in step (A4).

When the decorative material has a reinforcing layer, in step (B6), it is preferable to place the reinforcing layer on the surface of the base material B opposite the decorative layer. In other words, when the decorative material has a reinforcing layer, it is preferable that the laminate H includes the reinforcing layer.

Step (B7) is a step of hot pressing the laminate H (78) with both sides of the laminate H (78) sandwiched between mirror plates to form a second cured material layer 22 by curing the uncured curable resin composition layer 22a.
During the step (B7), the curable resin compositions impregnated in the substrate A and the substrate B can also be cured.

The conditions for the heat press can be adjusted appropriately depending on the type of thermosetting resin used, and there are no particular restrictions, but typically the temperature is between 100°C and 200°C, the pressure is between 0.1 MPa and 9.8 MPa, and the time is between 10 seconds and 120 minutes.

Step (B8) is a step of removing the laminate H from between the mirror plates.
In step (B9), when the release film is peeled off and removed from the laminate H, the second cured material layer on the first cured material layer of the second cured material layer is removed together with the release film to form a first region, and a second region is formed in which the second cured material layer formed in the area not having the first region-forming layer remains ( FIG. 2 ).
In step (B9), the second cured material layer on the first cured material layer is removed while the second cured material layer remains on the second region, so that after step (B9), the surface of the first region has a lower elevation than the surface of the second region.

Next, the following curable resin composition for forming a first cured material layer was printed on the other side of the paper, and cured by irradiation with an electron beam (applied voltage: 165 KeV, 3 Mrad (30 kGy)), to obtain a laminate A having a first cured material layer with a thickness t1 of 2.0 μm.
Next, the laminate A was impregnated with the following curable resin composition for forming the second cured material layer and dried to obtain a substrate A, which is a resin-impregnated paper having light transparency, and a laminate B was obtained by forming an uncured curable resin composition layer on the entire surface of the side of the laminate A having the first cured material layer (impregnated so that the amount of the cured resin composition when dried was 80 g/m ² ). The total light transmittance of the substrate A was 40% or more throughout the entire surface, and the haze was 96% or less. In addition, Hz1-Hz2 in the specification was about 10%. [Hz1-Hz2 were calculated as follows. First, the haze of the above paper (KJ Specialty Paper Co., Ltd., product number: OLP-38, basis weight: 42 g/m ² ) itself was regarded as Hz1. Next, the haze of the resin-impregnated paper obtained by impregnating the same paper with the curable resin composition for forming the second cured material layer and drying it was regarded as Hz2. Hz1-Hz2 was calculated from the above Hz1 and Hz2.]
Next, the release film described below was laminated on the surface of Laminate B having the uncured curable resin composition layer, and a reinforcing layer (three sheets of phenolic resin-impregnated core paper (Ohta Core, manufactured by Ohta Sangyo Co., Ltd.) having a basis weight of 245 g/ ^m2 obtained by impregnating craft paper with a liquid uncured resin composition made of phenolic resin) was laminated on the surface of Laminate B having the decorative layer, to obtain Laminate C.
Next, both sides of the laminate C were sandwiched between mirror plates, and a hot press machine was used to perform heat and pressure molding at a molding temperature of 150°C and a molding pressure of 100 kg/ ^cm2 for 10 minutes.
