Conventionally, a decorative molding material is known in which a design layer capable of imparting metallic luster, coloring, printed design and the like is formed on a plastic substrate.
The above decorative molding material can be used as a material for manufacturing various products in addition to the case where the decorative molding material itself can be used as a product, such as a nameplate or a mirror. For example, the decorative molding material is used. Then, by performing vacuum molding, press molding, or the like, it can be used to manufacture various molded products such as housings for audio products and other home appliances.

Examples of the decorative molding material and the manufacturing method thereof include, for example, a decorative molding material, a plastic base material, which is provided with a metallic luster by directly forming a metal thin film layer on a plastic base material as a base material by a vacuum deposition method or the like. A resin thin film (colored layer) mixed with a colorant is formed by coating, or a resin mixed with a colorant is melted and extruded with a T-die, and the plastic substrate itself is mixed with the colorant and colored. Examples of the molding material include a decorative molding material provided with a printed pattern by forming a printed pattern on a plastic substrate.
In addition, using a transfer material formed by appropriately combining the metal thin film layer, the colored layer, the printed layer, etc. on one side of the plastic film, the metal thin film layer, the colored layer, the printed layer, etc. are formed on the plastic substrate. A method for producing the formed decorative molding material can also be exemplified.
The decorative molding material produced in this way has a design property that combines metallic luster, coloring, printed design, and the like.

Furthermore, a method for producing a decorative molding material capable of simultaneously imparting a concavo-convex pattern, metallic luster, coloring, printed design, etc. to a plastic substrate, and a decorative molding material obtained by the production method are known. Yes.
The decorative molding material has a unique design with a combination of a concavo-convex pattern and metallic luster, coloring, printed design, and the like.
Patent Document 1 discloses a metallic luster pattern in which a fabric pattern such as a mesh or a line having the same or different desired marking depth is engraved on the surface of a substrate made of a molding material such as plastic such as a plastic substrate. The material (decorative molding material) is described.
Then, as described in the claims and FIG. 1, an endless belt 9 made of a heat-resistant metal material capable of stamping a fabric pattern laid between the silicon rubber roller 7 and the auxiliary roller 8, Heated by a plurality of heaters 6 installed on the open upper surface side where the belt is stretched, above the base material 2 made of a molding material such as plastic placed on the table 4 (the base material 2 and the belt) The belt 9 is brought into contact with a transfer film (transfer material) 11 (having a metallic luster) that is stretched between the substrate 2 and the surface of the substrate 2 with the same or different desired marking depth. Alternatively, a method of manufacturing a metallic glossy pattern material by engraving a linear (metallic glossy) fabric pattern is described.
It is also described that a heat-resistant fiber fabric such as a polyamide fiber nonwoven fabric can be used as the material of the endless belt 9 in place of the heat-resistant metal material that can be stamped.

JP-A-8-197900

However, the metallic gloss pattern material and the manufacturing method thereof described in Patent Document 1 have the following drawbacks.
(1) In the metallic glossy pattern material described in Patent Document 1, the method for forming the fabric pattern is as described above, and the endless belt made of a heat-resistant metal material capable of stamping the fabric pattern is continuously transferred. In the case where the base material that is the transfer object is a single sheet or plate as shown in FIG. The finished fabric patterns of each metallic luster pattern material will be exactly the same. In addition, when the substrate to be transferred is in the form of a roll such as a sheet (roll), the finished fabric pattern of each metallic glossy pattern material has a certain distance in the length direction (the same length as the belt). ), The same pattern was repeated, resulting in a monotonous fabric pattern with no change.
The purpose of this is to produce a metallic luster pattern material with a monotonous fabric pattern that has the same pattern as the fabric and knitted fabric with a monotonous pattern and does not change. In this case, there is no problem, but there is a problem that it is not possible to manufacture a metallic luster pattern material having a different fabric pattern for each product.
For example, using a non-woven fabric pattern characterized by a random fabric pattern, that is, various patterns in which fibers are intertwined and there is no two patterns in the width and length directions, Even if a metal glossy pattern material is manufactured using a non-woven fabric pattern belt for the purpose of producing a metal luster pattern material with a different fabric pattern, the same pattern does not change monotonously. It became a fabric pattern, and the above purpose could not be achieved.
(2) As described above, when a heat-resistant fiber woven fabric such as a polyamide fiber nonwoven fabric is used as the material of the endless belt 9, a seam is inevitably formed when the heat-resistant fiber woven fabric is formed into a belt shape. There was also a problem that the design of the metallic luster pattern material was spoiled and the design was impaired. In addition, when the emphasis is placed on the design, the joint portion of the metallic luster pattern material is removed (discarded), which causes a problem that the productivity is deteriorated.
(3) Furthermore, when heat-resistant fabric is used as the material for the belt, if the transfer is repeated many times, the fabric of the fabric is deformed by the heat and pressure during the transfer, and the desired fabric pattern is imparted to the substrate. There was a problem that made it difficult to do. For this reason, it is necessary to replace the belt with a new belt frequently, and there is a problem that productivity is deteriorated from this point.
(4) It was difficult to heat the belt uniformly because it was a method of heating a belt for imparting a fabric pattern to the substrate rather than heating the substrate itself as a transfer object. As a result, the metallic luster pattern material obtained by the phenomenon that the desired fabric pattern is not transferred, such as the fabric pattern is partially unclear or in some cases the fabric pattern is not transferred at all. In some cases, the fabric pattern was not obtained.
In particular, when the belt is made of a heat resistant fiber fabric, the above phenomenon is remarkable as compared with a belt made of a heat resistant metal material.

  The present invention eliminates all of the above-mentioned drawbacks, and has a concavo-convex pattern obtained by transferring the concavo-convex on the surface of the molding material, a metallic luster, coloring, a printed pattern, etc. The manufacturing method of the decorative molding material which can be provided to a material, and the decorative molding material manufactured by this manufacturing method are provided.

This is a method for producing a decorative molding material.
[2] The present invention relates to a method for producing a decorative molded material in which a design layer is laminated on a plastic substrate, and a transfer material having a design layer formed on one side of a plastic film on the plastic substrate is used as a design layer. Is placed on the plastic substrate side, and a molding material having at least one surface unevenness is placed on the plastic film of the transfer material so that the uneven surface is on the plastic film side. A step of obtaining a laminate in which a base material, a transfer material, and a shaping material are sequentially placed (A), a laminate obtained by superimposing a laminate and a metal plate is a set of polymers, and a plurality of polymers are stacked, The process (B) which heats this from both front and back surfaces to bring the plastic base material into a molten state, and pressurizes both layers of the polymer from both the front and back surfaces to thereby form a laminate in which the plastic base material is in the molten state.

It is.
[3] The present invention is a decorative molded material obtained by laminating a design layer on a plastic substrate, produced by the production method according to any one of [1] or [2] above, wherein the design layer And the uneven | corrugated pattern by which the said unevenness | corrugation of the shaping | molding material was transcribe | transferred is formed in the design layer side surface of a plastic base material at least .

Since the decorative molding material and the manufacturing method thereof according to the present invention have the above-described characteristics, the following excellent effects are obtained.
In the method for producing a decorative molded material of the present invention, the molding materials used in the steps (A) to (D) such as woven fabric, knitted fabric and nonwoven fabric are not used again in the steps (A) to (D). In order not to use it again, i.e., to make the molding material an endless belt like the manufacturing method described in Patent Document 1, and not to use it again (reuse),
1. As a molding material, the decorative molding material of the present invention manufactured using a molding material having random irregularities such as a nonwoven fabric, the plastic base material to be transferred is a sheet or plate of a sheet, The concavo-convex pattern of each finished decorative molding material becomes a random pattern that differs for each decorative molding material, and the concavo-convex patterns of all the decorative molding materials are not exactly the same. In addition, when the plastic base material to be transferred is a sheet (roll) in the form of a roll, the uneven pattern of each decorative molding material is the same uneven pattern in the width and length directions. There is no random uneven pattern, and there is no monotonous uneven pattern with no change in which exactly the same pattern is repeated at regular intervals (the same length as the belt).
2. Although the usage method of a shaping material is mentioned later, in the manufacturing method of this invention, the once used shaping material is not used again. Therefore, since the endless belt is not used for the purpose of reusing the shaping material, the decorative molded material produced by the production method of the present invention can not be seamlessly formed into a concavo-convex pattern. In addition, since it is not necessary to remove the seam portion, productivity does not deteriorate.
Furthermore, since it is not necessary to replace the belt with a new one, the productivity does not deteriorate from this point.
3. In the manufacturing method of the present invention, since the shaping material is used only once, the shaping material whose irregularities are once deformed by heat and pressure during transfer is not used again. Therefore, since the irregularities on the surface of the molding material are not deformed by heat or pressure during transfer, the decorative molding material produced by the production method of the present invention does not blur the irregular pattern. A desired concavo-convex pattern in which the concavo-convex is clearly transferred can always be formed on the decorative molding material of the present invention.
Moreover, in the method for producing a decorative molding material of the present invention, since the plastic substrate itself that is the transfer object is directly heated,
4). Since the plastic substrate is heated more uniformly than in the case of heating only the shaping material, the present invention manufactured by the manufacturing method of the present invention does not cause problems such as a desired uneven pattern not being partially transferred. The decorative molding material is surely formed with a clear uneven pattern.

The decorative molded material of the present invention produced by the method for producing a decorative molded material of the present invention described later is formed by laminating a design layer on a plastic substrate.
And, the decorative molding material of the present invention is characterized in that a concavo-convex pattern to which the concavo-convex of the surface of the molding material described later is transferred is formed on the design layer side and at least the design layer side surface of the plastic substrate. To do.
Here, the unevenness of the surface of the shaping material means the surface shape of the woven fabric, knitted fabric, nonwoven fabric or the like as the shaping material, that is, the fibers constituting the woven fabric, knitted fabric, nonwoven fabric or the like as the shaping material are the surfaces of the woven fabric, knitted fabric, nonwoven fabric, etc. This refers to the surface shape formed by exposing to the surface.
And, on the design layer side of the decorative molding material of the present invention manufactured using the molding material and at least the design layer side surface of the plastic base material, a concavo-convex pattern formed by inverting and transferring the surface shape of the molding material is formed. Will be.
Therefore, the concavo-convex pattern referred to in the present invention refers to a pattern in which the concavo-convex pattern on the surface of the shaping material is just inverted and transferred.
That is, a concave pattern is formed on the decorative molding material of the present invention by transferring the convex portions on the surface of the molding material, and formed on the decorative molding material of the present invention by transferring the concave portions on the surface of the molding material. Become a convex pattern.

First, the laminated body in which the plastic base material, the transfer material, and the shaping material used in order in the manufacturing method of the decorative molding material of the present invention will be described.
The laminate is placed on a plastic substrate with a transfer material having a design layer formed on one side of the plastic film so that the design layer is on the plastic substrate side, and further on the plastic film of the transfer material, It is obtained by placing a shaping material having irregularities on at least one surface so that the irregular surface is on the plastic film side.

The plastic base material used for the decorative molding material of the present invention is ABS (acrylonitrile butadiene styrene) resin, PS (polystyrene) resin, PP (polypropylene) resin, PC (polycarbonate) resin, PVC (vinyl chloride) resin, A resin such as an acrylic resin such as an AS (acrylonitrile) resin and a PMMA (polymethyl methacrylate) resin can be used, and among them, a thermoplastic resin is preferable.
The plastic substrate can be in the form of a sheet or plate.
Further, the plastic substrate may be either a single sheet or a long one that can be continuously produced.
The thickness, width, and length may be appropriately determined depending on the desired size of the decorative molded material of the present invention.

The transfer material used for producing the decorative molding material of the present invention is such that a design layer is formed on one side of a plastic film.
Here, the design layer refers to a decorative layer for imparting metallic luster, coloring, printing pattern, etc. to the decorative molding material of the present invention, that is, a metal thin film layer for imparting metallic luster, a colored layer for coloring In addition to the printed layer for imparting the printed pattern, the adhesive layer for bringing the decorative layer into close contact with the plastic substrate, and after transferring the design layer to the plastic substrate, the surface of the design layer is not damaged or corroded. It is a general term for all layers necessary for forming a desired decorative molding material by forming it on a plastic substrate, such as a protective layer to be protected.

A single layer may be sufficient as said metal thin film layer, a colored layer, and a printing layer which comprise a decorating layer, and in order to obtain a desired design, it is good also as a several layer combining these layers suitably.
For example, each of the decorative molding materials of the present invention can be a transfer material formed with a design layer combining a metal thin film layer and a colored layer, or a transfer material formed with a design layer combining a metal gloss layer and a printing layer. Colored metallic luster or printed pattern and metallic luster can be imparted respectively.
Further, the design layer may be formed on the entire surface of the transfer material, or may be partially formed.
Furthermore, each layer constituting the design layer, such as the metal thin film layer, the colored layer, the printed layer, the other protective layer, and the adhesive layer constituting the decorative layer, may be formed on the entire surface of the transfer material. It may be formed.
Which layer is formed on the entire surface or partially formed may be appropriately determined depending on the desired design of the decorative molded material of the present invention.
In this way, by forming each layer constituting the design layer entirely or partially on the transfer material, the decorative molded material produced by the production method of the present invention is also the design layer itself or each layer constituting the design layer. The decorative molding material is formed on the entire surface or a part thereof, and the decorative molding material of the present invention has a variety of design properties.

The metal thin film layer is not particularly limited as long as it can impart a metallic luster to the decorative molding material of the present invention. An aluminum thin film layer, a silver thin film layer, a copper thin film layer, a chromium thin film layer, a nickel thin film layer, tin A thin film layer or the like can be used.
What is necessary is just to determine the thickness of a metal thin film layer suitably by desired metal luster.
As a method for forming the metal thin film layer, a known method such as a vacuum deposition method can be used.

The colored layer is a thin film in which a colorant such as a dye or pigment is mixed in a resin such as an acrylic resin or a polyester resin, and can be formed by a known method such as a gravure coating method or a reverse coating method.
The amount of the colorant and the thickness of the colored layer may be appropriately determined depending on the desired degree of coloring.

The printing layer is a thin film formed by printing ink using a known method such as screen printing or gravure printing.
What is necessary is just to determine the design of a printing layer suitably with a desired printing design.

The adhesive layer is a thin film made of a resin, and is a layer for bringing the decorative layer into close contact with the plastic substrate.
The resin used for the adhesive layer is not particularly limited as long as it is a resin that can adhere to the plastic substrate, and resins such as acrylic resin, polyester resin, vinyl chloride resin, and vinyl chloride vinyl acetate copolymer resin can be used. What is necessary is just to determine suitably with the kind of plastic base material which is a transcription | transfer material.

The protective layer is a thin film made of resin and protects the surface of the design layer from scratches, corrosion, and the like.
The protective layer may be a layer having a hard coat property that is not particularly easily scratched.
The protective layer may be a layer that can be easily peeled off from the plastic film.
In such a case, it is not necessary to use a releasable plastic film in which a release layer described later is formed on the plastic film.
The resin used for the protective layer is not particularly limited as long as the surface of the design layer can be protected from scratches and corrosion, and resins such as acrylic resin, polyester resin, vinyl chloride resin, vinyl chloride vinyl acetate copolymer resin, etc. Can be used.

The plastic film is peeled off from the plastic substrate on which the design layer is formed after the transfer, and conventionally known plastic films such as polyethylene terephthalate film, polypropylene film, polyethylene film, polyamide film and the like can be used.
The thickness of the plastic film is preferably 3 to 50 μm.
When the thickness is less than 3 μm, it is not preferable because the plastic film is wrinkled when the decorative molded material of the present invention is manufactured. When the thickness is more than 50 μm, the surface of the molding material is uneven. Or the design layer cannot be clearly transferred, and as a result, a desired uneven pattern may not be formed on the decorative molding material of the present invention.

It is preferable to form a release layer made of a resin (between the plastic film and the design layer) on the plastic film so that the design layer can be easily peeled off from the plastic film.
The releasable plastic film having the release layer formed as described above is also included in the plastic film of the present invention.
In the case of a transfer material in which a release layer is formed on a plastic film, the release layer is peeled off from the plastic substrate on which the design layer is formed together with the plastic film after transfer.

Examples of the structure of the transfer material include structures of plastic film / release layer / protective layer / decorative layer / adhesive layer, plastic film / release layer / decorative layer / adhesive layer, and the like.

Further, the transfer material may be either a single sheet or a long length that enables continuous production of the decorative molding material of the present invention.
The thickness, width, and length may be appropriately determined depending on the desired size of the decorative molded material of the present invention.

The molding material used for producing the decorative molding material of the present invention is an irregularity in which irregularities on the surface of the molding material are transferred to the design layer side of the decorative molding material of the present invention and at least the design layer side surface of the plastic substrate. It is used to form a pattern.
The shaping material is a woven fabric, a knitted fabric, a non-woven fabric, or the like, and has at least one surface uneven.
Therefore, it does not matter if there are irregularities on both sides of the surface of the shaping material.

The material of the woven fabric or knitted fabric may be any of natural fibers such as cotton, wool, hemp and silk, or chemical fibers made of polyester resin, polypropylene resin, polyethylene resin, polyamide resin, acrylic resin and the like.
Examples of the weaving structure include plain weave, twill weave, and satin weaving. Examples of the knitting structure include weft knitting, flat knitting, rubber knitting, pearl knitting, and the like.
As the material for the nonwoven fabric, natural fibers and chemical fibers similar to those for woven fabrics and knitted fabrics can be used.

For example, when the molding material is woven or knitted fabric, the surface shape (unevenness) of the molding material can be easily adjusted by combining various weaving structures, knitting structures, fiber thicknesses to be used, etc. Moreover, it can be made into a wide variety, and as a result, the uneven pattern of the decorative molded material of the present invention produced using the shaping material can be easily made into a wide variety.
If the surface of the woven fabric or knitted surface is a monotonous surface that does not change by repeating the same pattern, such as making the woven or knitted fabric woven or knitted into a plain plain or flat knitted fabric, the woven fabric The decorative molding material of the present invention produced using a knitted fabric or knitted fabric has a monotonous uneven pattern having no change in which exactly the same pattern is repeated.
In addition, various woven and knitted patterns such as floral patterns and polka dots, or three-dimensional patterns by embroidery (a more three-dimensional pattern than a woven or knitted pattern) are formed on a part of the surface of a woven or knitted fabric. It may be used as a shaped material.
The decorative molding material of the present invention manufactured using such a molding material is a combination of the surface shape of the fibers constituting the woven fabric or knitted fabric and the design pattern to which the above-mentioned woven design, knitted design, and three-dimensional design are transferred. It will be something with a taste.
Furthermore, the decorative molding material of the present invention may have a taste that combines the surface shape of the fibers constituting the woven fabric or knitted fabric and the design pattern to which a flat design is transferred.
In order to form the above-mentioned design pattern on which a flat design has been transferred, a design in which a part of the surface of the woven fabric or knitted fabric is flattened is formed by coating a part of the surface of the woven fabric or knitted fabric with resin or the like. Alternatively, a method of cutting out a part of the woven fabric or the knitted fabric in a pattern shape can be mentioned.
The surface of the shaping material has unevenness (the depth of the recesses, the height of the protrusions, the shape of the recesses and protrusions, etc.), depending on the desired uneven pattern of the decorative molding material of the present invention. What is necessary is just to determine suitably by combining various the thickness etc. of the fiber to do.

As described above, since the material of the shaping material is natural fiber or chemical fiber, the shaping material is heated once in steps (A) to (D) in the method for producing the decorative molded material of the present invention described later. When the pressure is applied, the unevenness on the surface of the shaping material may be deformed.
For this reason, if the molding material of this invention is manufactured again by the manufacturing method of this invention, if the shaping material in which the unevenness | corrugation of the surface deform | transformed is used again, the decorative molding material of this invention will obtain a desired uneven | corrugated pattern. May be difficult.
Therefore, in order for the decorative molding material of the present invention to obtain a desired concavo-convex pattern with certainty, the shaping material should not be used again in steps (A) to (D) in the method for producing the decorative molding material of the present invention. Is preferred.
In addition, if the shaping material used in the steps (A) to (D) in the method for producing a decorative molding material of the present invention is not used again in the steps (A) to (D), the once-used shaping material is used as it is. This means that it is not used again in steps (A) to (D).
Accordingly, the molding material whose irregularities have been deformed by heat or pressure once used in the steps (A) to (D) is heated and humidified with, for example, steam (high-temperature steam), and thus deformed. When the molding material that reproduces the original irregularities in the original irregularities is used again in the steps (A) to (D) in the method for producing the decorative molded material of the present invention, the molding material that has been used once is left as it is. If not used, it will not be used again in steps (A) to (D).
Therefore, the molding material that reproduces the irregularities that have been deformed by heat and pressure after being used once into the original irregularities is used again in steps (A) to (D) in the method for producing a decorative molded material of the present invention. Such a case is also included in the production method of the present invention.

In addition, the shaping material may be either a single sheet or a long length that enables continuous production of the decorative molding material of the present invention.
The thickness, width, and length may be appropriately determined depending on the desired size of the decorative molded material of the present invention.

Next, the manufacturing method of the decorative molding material of this invention is demonstrated.
As described above, the method for producing a decorative composition according to the present invention is a method for producing a decorative molding material in which a design layer is laminated on a plastic substrate, and the design layer is provided on one side of the plastic film on the plastic substrate. The formed transfer material is placed so that the design layer is on the plastic substrate side, and a molding material having at least one surface unevenness is placed on the plastic film of the transfer material, and the uneven surface is on the plastic film side. A step (A) for obtaining a laminate in which a plastic substrate, a transfer material, and a molding material are sequentially placed, a step (B) for heating the plastic substrate to a molten state, and a plastic substrate Step (C) of obtaining a transfer laminate by pressing the laminate in which the material is in a molten state from at least the shaping material side and transferring the irregularities to the transfer material and at least the design layer side surface of the plastic substrate. An uneven pattern in which the unevenness of the shaping material is transferred to the design layer and at least the surface of the design layer of the plastic substrate by peeling the plastic film and the shaping material of the transfer material from the transfer laminate after cooling the transfer laminate. And forming the material used in the steps (A) to (D) is not used again in the steps (A) to (D).
The order of the steps (A) to (D) is as follows:
(1) Step (A), Step (B), Step (C), Step (D) Order (2) Step (B), Step (A), Step (C), Step (D) Order (3) The order in which step (A) is first performed, step (B) and step (C) are performed simultaneously, and step (D) is finally performed.

First, each step will be described.
<Process (A)>
First, a transfer material having a design layer formed on one side of a plastic film is placed on a plastic substrate so that the design layer is on the plastic substrate side.
Next, on the plastic film of the transfer material, a shaping material having irregularities on at least one surface is placed so that the irregular surface is on the plastic film side.
In this way, this is a step of obtaining a laminate in which the plastic substrate, the transfer material, and the shaping material are sequentially placed.
The plastic substrate, the transfer material, and the shaping material may be either a single wafer or a long sheet. In the case of a long sheet, it is preferable in handling that the sheet is wound around a roll.

<Process (B)>
This is a step of bringing the plastic substrate into a molten state by heating.
The purpose of bringing the plastic substrate into a molten state is to make the plastic substrate soft, so that in the step (C) and step (D) described later, desired irregularities on the design layer and at least the surface of the plastic substrate on the design layer side This is to form the pattern clearly.
Therefore, the molten state of the plastic substrate is only required to be soft enough to achieve the above object while maintaining the shape of the plastic substrate.
In addition, the entire plastic base material does not necessarily need to be in a molten state, and at least the design layer side surface of the plastic base material may be in a molten state as long as the above object can be achieved.
The heating temperature may be a temperature at which the plastic substrate is in a molten state, and may be appropriately determined depending on the type of the plastic substrate and the degree of the molten state (whether the molten state is the entire plastic substrate or only the surface).
The following method can be illustrated as a process (B).
(B-1) A method of heating the laminate with a heater such as infrared to bring the plastic substrate into a molten state (B-2) A method of heating the plastic substrate with a heater such as infrared to bring it into a molten state (B- 3) A method in which a laminated body (preferably the plastic substrate side of the laminated body) is placed along a heated rubber or metal roll to heat the plastic substrate to a molten state (B-4) A method of heating a plastic base material along a metal roll or the like to be in a molten state (B-5) Using an extrusion molding machine or the like, the resin used as the material for the plastic base material is melted and extruded from a T-die for melting. To obtain a plastic substrate in a state

<Process (C)>
In this step, the laminate in which the plastic substrate is in a molten state is pressed from at least the shaping material side, and the unevenness is transferred to the transfer material and at least the design layer side surface of the plastic substrate to obtain a transfer laminate.
Here, transferring the unevenness of the surface of the molding material to the design layer side surface of the transfer material and at least the plastic substrate means that the unevenness of the surface of the molding material is just inverted to the surface of the design layer side of the transfer material and at least the plastic substrate. Forming irregularities that can be formed, in other words, forming the surface of the transfer material and at least the design layer side of the plastic substrate into irregularities that are formed by inverting the irregularities of the surface of the shaping material.
Therefore, in the transfer laminate in the step (C), a concavo-convex pattern is formed on the transfer material (plastic film and design layer) and at least on the design layer side surface of the plastic base material, and the concavo-convex pattern on the surface of the molding material is just reversed. It has a structure.
In order to transfer the irregularities on the surface of the molding material to the surface of the transfer material and at least the design layer side of the plastic substrate, it is necessary to apply pressure from at least the molding material side.
The following method can be illustrated as a process (C).
(C-1) Method of pressurizing from the molding material side of the laminate with rubber or metal roll (C-2) Method of sandwiching the laminate with two rubber or metal rolls and pressing from the front and back sides (C- 3) A method in which a laminate and a metal plate are overlapped to form a set of polymers, a plurality of sets of the polymers are stacked on another metal plate, and this is pressed from both the front and back sides. Step (C) If the plastic substrate is not cooled and maintained in a molten state, the irregularities on the surface of the molding material cannot be reliably transferred to the transfer material and at least the design layer side surface of the plastic substrate.
Therefore, in order to reliably transfer the irregularities on the surface of the shaping material to the transfer material and at least the surface of the plastic base material on the design layer side, it is necessary that the plastic base material is maintained in a molten state during pressurization.
Examples of a method for maintaining the molten state of the plastic substrate during the pressurization include a method of heating a rubber or metal roll in the above (C-1) and (C-2).
Thus, in order to maintain the molten state of the plastic base material, the case where the apparatus for pressurizing at the time of pressurization is heated is also included in the pressurization referred to in the present invention.

<Process (D)>
After pressurization, after cooling the transfer laminate, the plastic film and the molding material of the transfer material are peeled off from the transfer laminate, and the unevenness of the molding material is transferred to the design layer and at least the design layer side surface of the plastic substrate. This is a step of forming the uneven pattern.
