SUMMARY OF THE INVENTION In a decorative material obtained by combining a printed pattern layer of wood grain and a colored resin layer in a recess of an emboss, generally, a recess by embossing, a filling ink by a wiping treatment, and a pattern printing. Since the layers do not exist on the same level surface and a design property different from that of the original document to be reproduced appears, unnaturalness remains. For example, since the position of the printed pattern layer of the wood pattern and the position of the colored resin layer in the recess expressing the conduit groove are formed deviating in the thickness direction, the wood pattern and the conduit groove of the natural wood board material Compared to the relationship, it looks unnatural and lacks delicacy.

On the other hand, according to the present invention, the printed pattern layer and the surface of the concave portion and the colored resin layer in the concave portion have the same level in the thickness direction of the decorative material, so that the printed pattern layer has, for example, a grain pattern. In the case of a decorative material having a pattern, in which the colored resin layer in the concave portion expresses a conduit groove, a decorative material having a novelty similar to a painted plate of natural wood is provided.

[0005]

The decorative material of the present invention comprises a base thermoplastic resin layer having a recess on the surface thereof, a colored resin layer filled in the recess, and the base thermoplastic resin. A transparent resin layer for the top laminated so as to cover the colored thermoplastic laminate in the recess with respect to the surface of the layer, and a back surface of the transparent resin layer for the top and / or The thermoplastic resin layer for the base has a printed pattern layer on the surface.

In the cosmetic material of the present invention having the above structure,
As the thermoplastic resin layer for the base, one having a thickness of about 25 to 300 μm, which is suitable for embossing, is used, and examples thereof include polyolefin resins such as polyethylene and polypropylene, polyvinyl chloride, polyvinylidene chloride, polyvinyl alcohol, ethylene. Vinyl-based resin such as vinyl acetate copolymer, ethylene / vinyl alcohol copolymer, polyester resin such as polyethylene terephthalate and polybutylene terephthalate, acrylic resin such as methyl polymethacrylate, methyl polyacrylate and ethyl polymethacrylate Films and sheets made of resins such as, polystyrene, acrylonitrile / butadiene / styrene copolymer (ABS), cellulose triacetate, cellophane, polycarbonate, and polyamide are used. Particularly preferred are tributyl phosphate, triphenyl phosphate, dimethyl phthalate, diethyl phthalate, dibutyl phthalate, octyl phthalate, butyl adipate, n-hexyl adipate, n-octyl adipate, dibutyl sebacate, diphenyl chlorate. A polyvinyl chloride sheet containing a plasticizer such as is used.

The thermoplastic resin layer for the base may be a single layer of the thermoplastic resin layer, or may be paper, non-woven fabric,
It may be a composite layer in which a backing material such as a metal plate or another thermoplastic resin layer is laminated. In addition, the thermoplastic resin layer for the base may be colored by kneading a pigment, printing the entire surface of the ink, or the like, if necessary. In particular, in the case of a decorative material that expresses wood grain, it is preferable that coloring that matches the color of the lightest part of the wood grain board material such as yellowish brown, brown, and beige is performed. Also,
When the cosmetic material has a hiding property, it is preferably colored with a colorant mainly containing a highly hiding pigment such as titanium white or carbon black.

The shape of the concave portion on the surface of the base thermoplastic resin layer is arbitrary, but the printing is formed on the back surface of the transparent resin layer for the top and / or the surface of the thermoplastic resin layer for the base described later. The shape is selected corresponding to the pattern layer. That is, when the printed pattern layer is a wood pattern, in the concave portion of the shape expressing the conduit groove or hairline of the plate material,
Further, when the printed pattern layer represents leather, it is formed into a concave portion having a shape representing a leather diaphragm, and when the printed pattern layer represents stones, the uneven surface of the cleaved surface of the granite plate, sand, etc. It is formed in a concave portion that expresses eyes and stucco, and when the printed pattern layer expresses a texture, it is also formed in a concave shape that expresses a stitch of the cloth and the like.

The depressions on the surface of the thermoplastic resin layer for the base are, for example, embossed plates having an embossed pattern of a conduit obtained by copying the unevenness of the wood surface by electroforming, or the unevenness of the wood surface. It is formed by an embossing plate or the like in which an embossed pattern of a conduit is formed by a photoetching method, using an original plate prepared by copying by a photoengraving method.

Further, when the thermoplastic resin layer for the base is a composite layer of thermoplastic resin layers, the resin layer forming the back surface layer and the resin layer forming the surface layer are laminated and at the same time embossed on the surface. It is preferable to form the thermoplastic resin layer for the base, which is the thermoplastic resin layer having the recess, by a so-called doubling embossing method for forming the recess.

The colored resin layer filled in the recesses on the surface of the thermoplastic resin layer for the base is, for example, natural resin such as shellac, cobal, dammar, rosin, rosin ester or its modified resin, nitrocellulose, acetyl. Cellulose, ethyl cellulose, cellulose derivatives such as benzyl cellulose, phenol resin, urea resin,
Phthalic acid resin, maleic acid resin, melamine resin,
Polyvinyl chloride / vinyl acetate copolymer resin, polyvinyl chloride resin, acrylic resin, polyvinyl alcohol, polyvinyl butyral, epoxy resin, silicone resin, polyester resin, polyamide resin, polyurethane resin, other synthetic resins 1, rubber derivatives such as chlorinated rubber, cyclized rubber, and synthetic rubber, and further ionizing radiation curable resins composed of prepolymers and / or monomers such as acrylates, esters, epoxies having a polymerizable unsaturated bond, etc. One or a mixture of two or more kinds as a vehicle, a coloring ink or paint in which carbon black, titanium white, rouge, ultramarine, colorants such as quinacridone, cyanine blue, extender pigments such as precipitated barium sulfate, and plasticizers are mixed. Formed by.

In order to fill the colored resin layer with the coloring ink to the paint in the concave portion on the surface of the base thermoplastic resin layer, the coloring ink to the paint is applied to the entire surface of the base thermoplastic resin layer. For example, a so-called wiping method is used in which after coating by roll coating, knife coating or the like, it is scraped off with a doctor blade or wiping paper, and the colored paint to ink is left only in the recesses. In this wiping step, the colored paint to the ink is filled and left only in the concave portion of the surface of the thermoplastic resin layer for the base,
It is necessary to adjust the viscosity of paint to ink, the rotation speed of the roll, the angle of the doctor, the thickness, the sheet speed, the speed of the wiping paper, the hardness of the rubber roll, and so on.

In the case of using a colored ink or a paint that uses an ionizing radiation-curable resin as a vehicle, a predetermined electron beam or ultraviolet ray irradiation treatment is performed following the wiping step, and the thermosetting resin is used. When using a resin as the vehicle, it goes without saying that the wiping step is followed by a thermosetting treatment. Especially colored inks that use electron beam or ultraviolet curable resin as a vehicle.
When a paint is used, the quality of the product can be stabilized and the production efficiency can be improved by forming a resin layer having a high crosslinking density and shortening the time required for drying.

Further, a transparent resin layer for the top is laminated on the entire surface of the thermoplastic resin layer for the base so as to cover the colored resin layer filled in the concave portion of the surface of the resin layer. It The transparent resin layer for this top is, for example,
It is composed of a colorless or colored transparent layer having a thickness of about 0.1 to 100 μm made of the above-mentioned ionizing radiation-curable resin or the like, such as polyester, polyvinyl chloride, acrylic resin, epoxy resin and the like. The transparent resin layer for the top can be formed, for example, by a coating method such as roll coating, knife coating, and air knife. In particular, a method of laminating a ready-made film to a sheet by dry lamination or thermal bonding is used. In that case, a transparent resin layer for a top having excellent surface physical properties is formed.

The printed pattern layer formed on the back surface of the transparent resin layer for the top and / or on the surface of the thermoplastic resin layer for the base is, for example, a wood grain pattern such as cedar board grain, a stone grain such as granite or marble. It is a pattern, a cloth pattern, a pattern on the surface of leather, an abstract pattern such as a lattice or a polka dot pattern, and a printed pattern layer corresponding to the shape of the concave portion on the surface of the thermoplastic resin layer for the base is attached.
When the printed pattern layer has a wood grain pattern, it is preferable to express the luster of the wood grain by using a print layer made of a glitter ink such as pearl ink.

[0016]

The decorative material of the present invention comprises the concave portion on the surface of the thermoplastic resin layer for the base, the colored resin layer filled in the concave portion, the rear surface of the transparent resin layer for the top and / or the base material. Since the surface of the printed pattern layer formed on the surface of the thermoplastic resin layer has the same level in the thickness direction of the decorative material, the concave portion, the colored resin layer filled in the concave portion, and Novelty is expressed in the design expressed by the printed pattern layer.For example, when the printed pattern layer has a wood grain pattern, the surface of the colored resin layer in the concave portion expressing the conduit groove or hairline of the plate material and the wood grain pattern. Since the printed pattern layer and the printed pattern layer have the same level in the thickness direction, the layer structure is extremely similar to that of a decorative material obtained by coating a natural plate material.
