Description

The present invention relates to a resin decorative sheet and decorative plate. In particular, the present invention relates to a technique relating to a decorative sheet that can be used as a flooring material and its periphery by being attached to a base material such as a wood-based material, and a decorative sheet thereof.

Decorative sheets have been developed and have been developed in the process of housing construction as an industry. It can be said that prefabricated buildings have played a leading role in apartments, condominiums, and individual houses, which are housing complexes.
Since ancient times, houses used materials that depend on local characteristics such as wood and stone, and people's homes had a style that was rooted in a unique culture.However, with the development of the housing industry, industrialization progressed, and the conversion from natural materials to artificial materials Has been done. Further, in recent years, the heavy use of high-grade wood and stone materials may lead to deforestation and environmental problems, which is one of the factors that increase the demand for decorative sheets.

For example, in recent years, a so-called sheet flooring material in which a decorative sheet is attached to the surface of a wood base material such as plywood, MDF (medium fiber version) or particle board has been widely used as a floor material (Patent Document 1). reference).
A decorative sheet for floors is used by pasting a decorative sheet on the surface of a base material that is a wooden floor material such as houses, stores, offices, gymnasiums, and among them, it is used for members such as climbing frames and stair treads. In that case, in addition to the scratch resistance normally required, bending workability is required so as to follow a curved surface or a right angle portion.

Also, after the completion of the interior decoration work for apartments, condominiums, and private houses, there will be room cleaning by the management company and beautifying companies. Gypsum board, putty such as putty, dust, etc. scattered on the floor are wiped and cleaned using water or detergent.
When wiping and cleaning the sheet flooring floor material, if the dry wiping property after wiping with water is heavy or if unevenness is apt to occur during wiping, there may occur a problem that it takes time to clean.

The present invention has been made in view of the above points, and has both scratch resistance and sliding resistance required as a floor material, and a decorative sheet having excellent cleaning properties as a decorative material, and The purpose is to provide a decorative board.

In order to solve the problems, the decorative sheet according to one embodiment of the present invention has a pattern layer, a transparent adhesive layer, a transparent thermoplastic resin layer, and a surface protective layer in this order on one surface side of a resin base sheet. The outermost layer, which is formed at least on the outermost surface of the surface protective layer, contains a liquid repellent and a spherical filler made of a resin, and the resin spherical filler is added to 100 parts by mass of the resin component of the outermost layer. It is characterized by containing 3 parts by mass or more and 15 parts by mass or less.

According to the aspect of the present invention, it is possible to provide a decorative sheet and a decorative sheet that have both scratch resistance and sliding resistance required as a flooring material and that also have excellent cleaning properties as a decorative material. ..

It is a figure explaining the cross-sectional schematic diagram of the decorative sheet which concerns on embodiment based on this invention.

Embodiments of the present invention will be described below with reference to the drawings.
In the present embodiment, the decorative sheet and decorative plate for the floor will be described as an example, but the decorative sheet and decorative plate used for other parts may be used.
Here, the drawings are schematic, and the relationship between the thickness and the plane dimension, the thickness ratio of each layer, and the like are different from the actual ones. In addition, the embodiments described below exemplify a configuration for embodying the technical idea of the present invention, and the technical idea of the present invention is that the material, shape, structure, etc. of the constituent parts are as follows. It is not specific to one. Various changes can be added to the technical idea of the present invention within the technical scope defined by the claims described in the claims.

As shown in FIG. 1, the decorative sheet 10 of the present embodiment has a pattern layer 2, a transparent adhesive layer 3, a transparent thermoplastic resin layer 4, and a surface protective layer 7 on a resin base sheet 1. It is formed by sequentially stacking. The present embodiment is an example in which the surface protective layer 7 is composed of two layers, a first surface protective layer 5 and a second surface protective layer 6.
A backside resin coat layer 8 made of a resin layer is provided on the surface (backside) of the base sheet 1 opposite to the pattern layer 2.

[Veneer]
Further, the decorative board 20 is configured by laminating the decorative sheet 10 on a base material 11, as shown in FIG.
[Base material 11]
As the base material 11, South Sea wood plywood, particle board, medium density fiberboard (hereinafter MDF), and ordinary plywood specified in Japanese Agricultural Standards can be used. Further, a base material made of an olefin resin added with wood powder can also be used. The thickness of the base material 11 is preferably about 3 to 25 mm. The base material 11 may be a metal plate such as aluminum or a composite plate made of metal.

[Base material sheet 1]
The resin base sheet 1 is made of, for example, a colored thermoplastic resin. As the thermoplastic resin, for example, vinyl chloride resin, acrylic resin, polyolefin-based polypropylene resin or polyethylene resin can be used. Of these, polyolefin resins can be preferably used in view of environmental compatibility, processability, and price. In addition, the grade and composition of the resin can be selected in consideration of ease of sheeting, printability and suitability for bending.
When the base material sheet 1 is colored, the base material to which the decorative sheet 10 is attached can be hidden, and the hue can be appropriately selected as the base color of the pattern layer 2. For example, coloring can be performed by mixing and kneading a colorant such as a pigment during sheeting of the thermoplastic resin. Alternatively, a colored layer may be provided as a solid ink layer before providing the pattern layer 2 by using a coating or printing method under the pattern layer 2.

[Pattern layer 2]
The picture pattern layer 2 can be provided using a known printing method. When the base material sheet 1 can be prepared in a wound state, printing for forming the pattern layer 2 can be performed by a roll-to-roll printing device. The printing method is not particularly limited, but if productivity and the quality of the pattern are taken into consideration, for example, the gravure printing method can be used.
As the design pattern, any design pattern may be adopted in consideration of the design as a flooring material, and in the case of wood-based design, various wood grain is often used. Can also be For example, if it is an image of a floor of a stone material such as marble, it may be used as a pattern pattern such as marble stones. Further, in addition to the picture patterns of natural materials, artificial picture patterns such as artificial picture patterns and geometric patterns using them as motifs can also be used.

The printing ink is not particularly limited, but an ink corresponding to the printing method can be appropriately selected. In particular, it is preferable to select it in consideration of adhesion to the resin base sheet 1, printability, and weather resistance as a floor material.
In addition, if necessary, an adhesive layer (non-adhesive layer) is formed on the pattern pattern layer 2 for the purpose of improving the adhesiveness between the pattern pattern layer 2 and the transparent adhesive layer 3, and between the transparent adhesive layer 3 and the transparent thermoplastic resin layer 4. (Illustration) may be provided. The resin used for this adhesive layer (not shown) is not particularly limited, but, for example, a two-component curing type urethane resin or the like can be used, and can be provided by using, for example, a coating device or a gravure printing device.

[Transparent adhesive layer 3]
The transparent adhesive layer 3 is provided for the purpose of strengthening the adhesion between the base sheet 1 and the pattern layer 2 and the transparent thermoplastic resin layer 4. By virtue of this strong adhesion, it is possible to give the decorative sheet 10 bendability that follows a curved surface or a right-angled surface.
[Transparent thermoplastic resin layer 4]
For the transparent thermoplastic resin layer 4, for example, vinyl chloride resin, acrylic resin, polyolefin-based polypropylene resin or polyethylene resin, or the like can be used. Of these, polyolefin resins can be preferably used in view of environmental compatibility, processability, and price.

In addition, the grade and composition of the resin can be selected in consideration of ease of sheeting, printability and suitability for bending. In particular, in terms of bending workability, it is important to select in consideration that whitening or cracking of the bent portion does not occur.
The transparent adhesive layer 3 and the transparent thermoplastic resin layer 4 can be formed, for example, by co-extruding both.
By the transparent thermoplastic resin layer 4, the decorative sheet 10 has an effect of having a thickness and a depth in design, and can also improve weather resistance and abrasion resistance of the decorative sheet 10.

[Surface protection layer 7]
A surface protection layer 7 is provided on the transparent thermoplastic resin layer 4. The surface protective layer 7 may be a single layer, or a plurality of layers may be stacked to form the surface protective layer 7. In the decorative sheet 10 of the present embodiment, as shown in FIG. 1, as the surface protective layer 7, two layers of a first surface protective layer 5 and a second surface protective layer 6 are provided. The surface protective layer 7 may be composed of one layer. In this case, the second surface protective layer 6 becomes the surface protective layer 7.
In order to provide the surface protective layer 7 composed of the first surface protective layer 5 and the second surface protective layer 6, the respective layers are formed by known coating devices, heat drying devices, and ultraviolet irradiation devices depending on the type of curable resin. Can be used for coating and curing of the coating film.

The surface protective layer 7 has an important role in determining the superiority and inferiority of bending workability, scratch resistance, and cleanability. The surface protective layer 7 contains a curable resin as a main component. That is, it is preferable that the resin component is substantially composed of a curable resin. Substantially means, for example, 80 parts by mass or more when the entire resin is 100 parts by mass. The surface protective layer 7 may contain a weathering agent, a plasticizer, a stabilizer, a filler, a dispersant, a dye, a colorant such as a pigment, a solvent, or the like, if necessary.
Irregularities may be formed on the surface of the surface protective layer 7 in order to impart a given design property. Usually, an uneven pattern is formed by embossing. The embossing method is not particularly limited. A known sheet-fed or rotary embossing machine is used for the embossing. Examples of the concavo-convex shape include a wood grain board conduit groove, a stone board surface irregularity (granite cleaved surface, etc.), a cloth surface texturer, a satin finish, a sand grain, a hairline, a line groove, etc.

[Second surface protective layer 6]
The second surface protective layer 6 is the outermost layer located on the outermost surface of the surface protective layer 7. The second surface protective layer 6 contains an ionizing radiation curable resin. A liquid repellent agent and a spherical filler made of resin are added to the second surface protective layer 6. In addition, in this embodiment, as the ionizing radiation curable resin, an ultraviolet curable resin is appropriately described as a representative.
The second surface protective layer 6 may further contain a thermosetting resin. However, even in this case, the content ratio of the curable resin is 50% or more of the total amount of the ionizing radiation curable resin.
Here, it is important to make a selection especially in consideration of cleanability. As a result of intensive studies on this point, we were able to find the following findings.
That is, the main component of the second surface protective layer 6, which is the outermost layer of the surface protective layer 7, is a mixture of an ultraviolet curable resin and a thermosetting resin, so that scratch resistance when used on a floor is satisfied. At the same time, it was found that whitening and cracking of the surface protective layer 7 are less likely to occur during bending.

From this knowledge, it is preferable that at least the second surface protective layer 6, which is the outermost layer, of the surface protective layer 7 is made of a mixture of an ultraviolet curable resin and a thermosetting resin. Of course, other additives may be appropriately added to the mixture. In particular, the mixing ratio of the ionizing radiation curable resin and the thermosetting resin is set to be in the range of 7:3 to 9:1 by mass ratio, that is, the ultraviolet curable resin is 70 to 90 in the mixture. % Mass, and the thermosetting resin is preferably 10 to 30% mass. The above-mentioned main component refers to, for example, 70% or more of the total amount of the mixture of the ultraviolet curable resin and the thermosetting resin.
In this way, the main component of the second surface protective layer 6, which is the outermost layer of the surface protective layer 7, is a mixture of an ultraviolet curable resin and a thermosetting resin, so that scratch resistance when used for a floor. At the same time, the surface protection layer 7 is less likely to be whitened or cracked during bending.

Here, the ionizing radiation curable resin is not particularly limited, and a prepolymer (including an oligomer) and/or a radically polymerizable double bond in the molecule capable of undergoing a polymerization and crosslinking reaction by irradiation with ionizing radiation such as ultraviolet rays or electron beams, and/ Alternatively, a transparent resin containing a monomer as a main component can be used. These prepolymers or monomers may be used alone or in combination of two or more. The curing reaction is usually a crosslinking curing reaction.
Specifically, the prepolymer or the monomer is a compound having a (meth)acryloyl group, a radically polymerizable unsaturated group such as a (meth)acryloyloxy group, or a cationically polymerizable functional group such as an epoxy group in the molecule. Are listed. A polyene/thiol-based prepolymer obtained by combining polyene and polythiol is also preferable. Here, the (meth)acryloyl group means an acryloyl group or a methacryloyl group.

Examples of the prepolymer having a radically polymerizable unsaturated group include polyester (meth)acrylate, urethane (meth)acrylate, epoxy (meth)acrylate, melamine (meth)acrylate, triazine (meth)acrylate, and silicone (meth)acrylate. Etc. The molecular weight of these is preferably about 250 to 100,000.
Examples of the monomer having a radically polymerizable unsaturated group include, as monofunctional monomers, methyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, phenoxyethyl (meth)acrylate and the like. Examples of polyfunctional monomers include diethylene glycol di(meth)acrylate, propylene glycol di(meth)acrylate, trimethylolpropane tri(meth)acrylate, trimethylolpropane ethylene oxide tri(meth)acrylate, dipentaerythritol tetra( Examples thereof include (meth)acrylate, dipentaerythritol penta(meth)acrylate, and dipentaerythritol hexa(meth)acrylate.

Examples of the prepolymer having a cationically polymerizable functional group include prepolymers of bisphenol type epoxy resins, epoxy resins such as novolac type epoxy compounds, and vinyl ether resins such as fatty acid vinyl ethers and aromatic vinyl ethers. Examples of thiols include polythiols such as trimethylolpropane trithioglycolate and pentaerythritol tetrathioglycolate. Examples of the polyene include those obtained by adding allyl alcohol to both ends of polyurethane made of diol and diisocyanate.

As the ionizing radiation used to cure the ionizing radiation curable resin, electromagnetic waves or charged particles having energy capable of causing a curing reaction of molecules in the ionizing radiation curable resin (composition) are used. Usually, ultraviolet rays or electron rays may be used, but visible rays, X-rays, ion rays or the like may be used.
As the ultraviolet ray source, for example, a light source such as an ultra-high pressure mercury lamp, a high pressure mercury lamp, a low pressure mercury lamp, a carbon arc lamp, a black light, a metal halide lamp can be used. The wavelength of ultraviolet rays is usually preferably 190 to 380 nm.

As the electron beam source, for example, various electron beam accelerators such as Cockcroft-Walton type, Van de Graft type, resonance transformer type, insulating core transformer type, linear type, dynamitron type, high frequency type and the like can be used. Among them, those capable of irradiating with an electron having an energy of 100 to 1000 keV, preferably 100 to 300 keV are preferable.
The two-component curing type urethane resin is not particularly limited, but among them, a polyol component having an OH group as a main component (acrylic polyol, polyester polyol, polyether polyol, epoxy polyol, etc.) and an isocyanate component as a curing agent component (tolylene diene) Isocyanate, hexamethylene diisocyanate, meta-xylene diisocyanate, etc.) can be used.

[Liquid repellent]
The liquid repellent preferably has at least oil repellency. The liquid repellent is composed of, for example, at least one of a silicone compound and a fluorine compound.
It is preferable that the liquid repellent is contained in an amount of 0.1 part by mass or more and 30 parts by mass or less based on 100 parts by mass of the resin component forming the second surface protective layer 6.
Examples of the fluorine-based compound include tetrafluoroethylene, tetrafluoroethylene-ethylene copolymer, polyvinylidene fluoride, and the like, and many other derivatives can be used.
Examples of silicone compounds include modified silicones. In particular, when silicone is used, modified silicone is preferably used because of problems of adhesion and compatibility with the surroundings.

Modified silicones can be classified into reactive modified silicones and non-reactive silicones. Examples of the heat-reactive modified silicone include monoamine-modified silicone, diamine-modified silicone, epoxy-modified silicone, carbinol-modified silicone, carboxy-modified silicone, mercapto-modified silicone, silanol-modified silicone, alcohol-modified silicone and diol-modified silicone. Examples of the ionizing radiation-reactive modified silicone include acrylic modified silicone and methacrylic modified silicone. Further, non-reactive modified silicones such as polyether modified silicone, aralkyl modified silicone, long chain alkyl modified silicone and higher fatty acid ester modified silicone can be exemplified.
When the curable resin forming the second surface protective layer 6 is an ionizing radiation curable resin, the modified silicone is preferably an ionizing radiation reactive modified silicone. When the curable resin forming the second surface protection layer 6 is a mixture of an ionizing radiation curable resin and a thermosetting resin, the modified silicone has at least one of ionizing radiation reactivity and heat reactivity. It is preferably a modified silicone.

[Spherical filler]
The spherical filler made of resin is made of resin such as polyethylene or polypropylene.
The addition amount of the spherical filler is adjusted so as to be in the range of 3% by mass or more and 15% by mass or less based on 100 parts by mass of the resin component forming the second surface protection layer 6. The size (diameter) of the spherical filler made of resin is, for example, in the range of 3 μm to 8 μm in average particle diameter. The spherical filler may be added to the first surface protective layer.
By containing 3% by mass or more and 15% by mass or less of the spherical filler made of resin, it becomes possible to provide a decorative floor sheet having good sliding resistance and scratch resistance.
Here, by making the material of the spherical filler resin, since the filler has elasticity compared to the spherical filler made of glass, it is better to make the material of the spherical filler resin is a glass spherical filler. The sliding resistance and the scratch resistance are improved as compared with the case of In the case of a spherical filler made of glass, the transparency is good, but depending on the particle size, the contacted object may be unnecessarily damaged or the scratch resistance may be deteriorated.

Further, by using polyethylene or polypropylene as the resin spherical filler, it is possible to ensure transparency close to that when using a glass spherical filler.
Further, by adding a matting agent such as silica to the second surface protective layer 6 and adjusting the composition of the matting agent and the amount thereof to be added, a 60-degree mirror surface of the second surface protective layer 6 according to JIS Z 8741. The gloss value may be adjusted to have a desired gloss level according to the purpose of the decorative sheet 10. For example, the desired 60-degree specular gloss is in the range of 5 or more and less than 20, or in the range of 20 or more and 35 or less.

In this way, by setting the value of the 60-degree specular gloss of the second surface protective layer 6 according to JIS Z 8741 to 5 or more and 35 or less, unevenness after wiping during cleaning becomes conspicuous as described later. ..
Here, as the glossiness becomes higher, the wiping-off property is improved, but the designability is impaired accordingly. The value of the 60-degree specular gloss is set to 5 or more and 35 or less in consideration of improving the wiping-off property and imparting a design property more than required. At this time, when relatively importance is attached to the design property, it may be adjusted to 5 to 20, and when relatively importance is attached to the improvement of the wiping property, it may be adjusted to 20 to 35.

[First surface protective layer 5]
For the first surface protective layer 5, a resin having the same composition as that of the second outer surface protective layer 6, which is the outermost layer, may be used, or different types, compositions, and ratios of the resins may be used. ..
The decorative pattern layer 2 side of the decorative sheet 10 is as described above, but when the decorative sheet 10 is attached to a wooden base material to be used as the decorative board 20 or further processed into a member, a resin base material sheet is used. The back surface resin coat layer 8 which is a resin layer containing silica powder may be provided on the surface opposite to the pattern layer 2 of both the front and back surfaces of No. 1 to improve the adhesive strength with the wooden base material 11. As the adhesive used for this bonding, for example, an emulsion type adhesive of ethylene vinyl acetate copolymer can be used.
The decorative sheet 10 of the present embodiment having the above-described material configuration has cleanability, scratch resistance and bending workability as a floor material, and is particularly suitable as the decorative sheet 10 for a floor material. is there. The decorative sheet 10 of the present embodiment is not limited to being applied to a floor material, but can be applied as a decorative sheet for a decorative material used around the floor surface such as a step board of stairs.

This embodiment has the following effects.
(1) In the surface protective layer 7, at least the outermost second surface protective layer 6, which is the outermost layer, contains a liquid repellent agent and a resin spherical filler.
According to this configuration, the liquid repellent agent is added to at least the outermost surface of the surface protective layer 7, and the wiping property is improved. Further, by adding a spherical filler made of resin, the spherical filler made of resin suppresses the falling of the liquid repellent and improves the sliding resistance.
Further, when the addition amount of the spherical filler made of resin is large, the scratch resistance is adversely affected. In view of this, the spherical filler made of resin is specified to be contained in an amount of 3 parts by mass or more and 15 parts by mass or less.
As a result, the decorative sheet of the present embodiment has an effect that both the sliding resistance and the scratch resistance are achieved, and the cleaning property is easily maintained.

Hereinafter, the present invention will be described more specifically and in detail with reference to Examples, but the present invention is not limited to these Examples.
<Example 1>
A polyethylene film (“FZ” manufactured by RIKEN TECHNOS CORPORATION) was used as the base sheet. On one surface of the base sheet, a grain pattern was printed with a gravure printing machine using a gravure ink (“Lamistar” manufactured by Toyo Ink Mfg. Co., Ltd.) as a pattern layer to provide a pattern layer.
Further, a resin layer was formed on the surface of the substrate sheet opposite to the pattern layer by gravure coating of a two-component urethane type primer resin containing silica powder so that the thickness after drying would be 1 μm.

Further, a two-component urethane resin adhesive containing polyester polyol as a main component and isophorone diisocyanate as a curing agent was coated on the pattern layer so that the coating amount after drying was 2 g/m ² .
After that, a transparent adhesive layer (maleic acid-modified polypropylene resin) 10 μm and a transparent thermoplastic resin layer 115 μm containing polypropylene having a 95% isotactic pentad fraction (made by Prime Polymer Co., Ltd.) as a main component are transparently adhered. Coextrusion lamination was performed so that the layer was on the pattern layer side.

Further, as a first surface protective layer, a thermosetting polyfunctional acrylic urethane resin (manufactured by DIC Graphics Co., Ltd.) was applied on the surface of the transparent thermoplastic resin layer in a thickness of about 9 μm after drying, 1 A surface protective layer was formed.
Then, as the second surface protective layer, a thermosetting polyfunctional acrylic urethane resin (manufactured by DIC Graphics Co., Ltd.) and an ultraviolet curable polyfunctional urethane acrylate resin (DIC graphics ( Co., Ltd.) as a main component and containing a spherical polyethylene filler and a modified silicone (oil repellent component) with a thickness of about 6 μm after drying to form a second surface protective layer. Here, the content of the spherical polyethylene filler was adjusted to 3 parts by mass and the content of the modified silicone was adjusted to 5 parts by mass with respect to 100 parts by mass of the resin component.
Subsequently, the ultraviolet curable resin was cured by irradiation with ultraviolet rays to obtain the floor decorative sheet of Example 1.

<Example 2>
A floor decorative sheet of Example 2 was obtained by the same procedure as in Example 1 except that the amount of the spherical polyethylene filler contained in the second surface protective layer was adjusted to 10%.
<Example 3>
A floor decorative sheet of Example 3 was obtained by the same procedure as in Example 1 except that the amount of the spherical polyethylene filler contained in the second surface protective layer was adjusted to 15%.
<Comparative Example 1>
A floor decorative sheet of Comparative Example 1 was obtained by the same procedure as in Example 1 except that the second surface protective layer did not contain the spherical polyethylene filler.
<Comparative example 2>
A decorative sheet for floor of Comparative Example 2 was obtained by the same procedure as in Example 1 except that the amount of the spherical polyethylene filler contained in the second surface protective layer was adjusted to 20%.

[Performance evaluation]
The floor decorative sheets of Example 1, Example 2, Example 3, Comparative Example 1 and Comparative Example 2 were used as a two-liquid aqueous emulsion adhesive (Chuo Rika Kogyo ( Co., Ltd. “Rica Bond” (mass ratio BA-10L/BA-11B=100:2.5)) was applied in a wet state to 100 g/m ² and then bonded together, and cured for 24 hours to obtain a floor decorative plate. did. These decorative floor boards were evaluated by the following methods.
<Hoffman scratch test>
Using a Hoffman scratch hard nester (manufactured by BYK-Gardner), the load was changed from 200 g to 2000 g in 200 g increments, and scratched.
As an evaluation method, the case where the minimum load for peeling off the coating film was 1400 g or more was "O", and the case where it was 1200 g or less was "X".

<Steel wool test>
Bonsters #0-1 were made to reciprocate 20 times with the load of 250 g/cm< ² >.
As an evaluation method, "○" was given when the surface was not scratched, and "x" was given when the surface was scratched.
<Slipper sliding test>
Sliding motion of 200,000 reciprocating motions was applied to a slipper made of vinyl chloride material under a load of 45 g/cm ² .
As an evaluation method, a sample having no significant change in appearance was rated as "good", and a sample having a scratch on the surface or having a gloss change of 5 or more was rated as "bad".

<Magic wiping test>
A line was written on the surface of the floor decorative material with a commercially available oil-based black magic marker, and then wiped dry with a bencott.
As an evaluation method, “○” means that the magic was wiped off after wiping off, and “x” means that the magic remained without being wiped off.
The evaluation results are shown in Table 1.

By adding an oil-repellent component to the second surface protective layer and adding an oil-repellent component, the magic wiping property is advantageous, but if spherical fillers are not added as in Comparative Example 2, after the slipper sliding test is performed. Does not last because the oil repellent component falls off. On the other hand, as in Examples 1 to 3, by containing the spherical filler made of resin, the sliding resistance is advantageously exerted, and the effect of the oil repellent component is maintained. Sex is considered to be advantageous.
In addition, when a large amount of spherical filler is contained as in Comparative Example 2, the scratch resistance represented by the steel wool test is adversely affected. However, as in Examples 1 to 3, when the content of the resin spherical filler is in the range of 3 to 15%, it can be seen that the deterioration of scratch resistance can be suppressed.
That is, it is understood that in Examples 1 to 3, both scratch resistance and sliding resistance are compatible with each other, and the cleaning property represented by the magic wiping property is maintained.
