BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface decoration method for wood and metal plates. More specifically, it is used for decoration or surface of household appliances, office machines, vehicle interior materials, other various furnitures, building interior materials, etc. The present invention relates to a decorative material in which the uneven surface layer used for the purpose of protection has a change in matte degree.

[0002]

2. Description of the Related Art Conventionally, household appliances, furniture and interior materials for construction,
For decorative materials such as wood and metal plates used for interior materials such as automobiles, a picture layer is printed on a plastic film, a transparent film is laminated if necessary, and an uneven pattern is given to the surface, or the gloss is changed. It is constructed by providing a topcoat layer over the entire surface. When the top coat layer was provided on the entire surface, it was not possible to express the gloss difference in synchronization with the uneven pattern layer. There is also a decorative material in which a concave portion of the uneven pattern layer is filled with a paint so that the pattern layer and the uneven pattern layer are synchronized with each other to give an appearance similar to a natural material.
However, although this type of decorative material is said to be similar in appearance to natural materials, it does not have so-called "shining" from the inside of the material, has a poor three-dimensional effect, and has a gloss difference close to that of natural materials. There was a problem that it was not expressed.

[0003]

DISCLOSURE OF THE INVENTION The present invention provides a matte topcoat layer having a gloss change corresponding to the uneven pattern of a decorative material, that is, a so-called "shining" from the inside of the material, and a three-dimensional object close to natural. It is an object of the present invention to provide a matte cosmetic material which has a feeling and which sufficiently expresses the difference in gloss.

[0004]

In order to achieve the above object, in the decorative material of the present invention, a matting agent is provided on the topcoat layer in the decorative material in which concave portions and a topcoat layer are sequentially formed. Of which the particle size is larger than that of the concave shape and the particle size of which is smaller. A second invention is that the topcoat layer of the above invention is composed of an ionizing radiation curable resin.

The decorative material K of the present invention is, as shown in FIG. 1, a decorative material in which a concave shape 5 and a top coat layer 4 are sequentially formed on the surface of a decorative sheet provided with a pattern layer 3 if necessary. The particle size of the matting agent in the top coat layer 4 is larger than the diameter of the concave shape [M1] 41.
And a small matting agent [S1] 43. The top coat layer is made of an ionizing radiation curable resin.

The colored film 1 constituting the decorative sheet 12 shown in FIG. 2 is not only a film made of almost all thermoplastic resins but also paper, synthetic paper, and non-woven fabric, similar to those used in conventional decorative materials. Etc. can be used. For example, polyamide such as 6 nylon and 66 nylon, polyethylene,
Polyolefins such as polypropylene, polyvinyl chloride, vinyl resins such as polyvinyl butyral, ethylene / vinyl acetate copolymers, ethylene / vinyl alcohol copolymers, ethylene / acrylic acid copolymers, ethylene /
Polyolefin-based copolymers such as acrylic acid ester copolymers, polyethylene terephthalate, polyesters such as polybutylene terephthalate, polymethacrylic acid methyl, polymethyl acrylate, acrylic resin such as polymethacrylic acid ethyl, polystyrene, Acrylonitrile-butadiene-styrene copolymer (AB
S), cellulose triacetate, polycarbonate and the like are single layer or laminated films colored with a normal coloring material having excellent durability. A preferred colored film is polyvinyl chloride or polystyrene having a thickness of 50 to 150 μm, which is excellent in moldability of an uneven pattern and processability such as lamination.

The printing ink for forming the pattern layer 3 may be an ink which has been conventionally and generally used and has excellent light resistance while firmly adhering to the colored film, and preferably capable of being heat-bonded to the transparent film to be laminated. Is. For example, when printing on a polyvinyl chloride film, heat lamination can be performed by selecting a polyvinyl chloride film as a transparent film by using an ink having a thermoplastic vinyl chloride / vinyl acetate copolymer as a binder. And the printing method of the method of forming the pattern layer is
Although any of sheet-fed, winding planographic, intaglio, stencil, and letterpress can be used, it is preferable to use gravure printing or flexographic printing capable of ordinary winding printing due to the variety of ink binders and ease of post-processing. , Silk screen printing.

As the transparent film 2 which constitutes the decorative sheet 12 shown in FIG. 2, it is possible to select and use the transparent film 2 which is made of almost all the thermoplastic resin, similar to the conventional transparent film. For example, polyamide such as 6-nylon and 66-nylon, polyolefin such as polyethylene and polypropylene, vinyl-based resin such as polyvinyl chloride and polyvinyl alcohol, ethylene / vinyl acetate copolymer, ethylene / vinyl alcohol copolymer, ethylene / acrylic acid Copolymers, olefinic copolymers such as ethylene / acrylic acid ester copolymers, polyesters such as polyethylene terephthalate and polybutylene terephthalate,
In addition to acrylic resins such as methyl polymethacrylate, methyl polyacrylate, and ethyl polymethacrylate, single layers of polystyrene, acrylonitrile-butadiene-styrene copolymer (ABS), cellulose triacetate, polycarbonate, etc. or There are laminated films. Preferred is a film of polyvinyl chloride having a thickness of 50 to 150 μm, which is excellent in moldability of an uneven pattern and processability such as lamination.

The transparent film and the colored film provided with the pattern layer are laminated by a usual method such as dry lamination by applying an adhesive, wet lamination, or heat lamination by heating the film to adhere it in a molten state. Can be adopted. Heat lamination of a pattern layer of a colored film printed with an ink using a vinyl chloride / vinyl acetate copolymer as a binder and a transparent polyvinyl chloride film is preferable. And
In this lamination, the concave shape 5 can be simultaneously formed at the time of pressure bonding.

The concave shape of the present invention forms an uneven pattern of an embossing plate on the surface of a transparent film laminated on a colored film by heat and pressure. A machine such as a lithographic press or a roll embossing machine can be used as a method for imprinting the uneven pattern. Roll embossing machines are preferred when processing the windings of the present invention. The heating and pressurizing conditions of the material differ depending on the thermocompressive behavior of the transparent film, but in the case of a normal thermoplastic resin, heating to an appropriate temperature between the softening point, heat distortion temperature, and melting temperature, Press the embossed plate to shape,
Cool to fix shape. For heating during embossing, infrared irradiation, hot air blowing, conduction heat from the heating roller,
A known method such as dielectric heating is used. The concave pattern is
There are natural patterns such as wood grain, stone grain, cloth grain and sand grain, letter symbols, lines, wave patterns, various abstract pattern patterns and matte surfaces.

The depth and width of the concave shape are determined in consideration of the design to be expressed and the particle size of the matting agent used.
The depth of the concave shape is 5 to 10 μm, and its diameter is
Alternatively, the width is preferably 3 to 30 μm. The width of the concave shape is 3μ
When it is m or less, a matting agent having a small particle size cannot be deposited in the concave portion, and when it is 30 μm or more, the particle size is large or small.
The matting agent is evenly distributed and the difference in gloss cannot be exhibited. By providing the concave shape with a width of 5 to 30 μm, a matting agent having a small particle diameter is deposited in the concave portion, and a matting agent having a large particle diameter is removed from the convex portion to form particles on the surfaces of the concave portion and the convex portion. By depositing matting agents having different diameters, the difference in matting degree is realized.

The resin forming the top coat layer is classified into a solvent drying type and a reaction curing type. Examples of the solvent-drying type include, in addition to cellulose derivatives such as ethyl cellulose and cellulose acetate butyrate, acrylic resins, vinyl polymers such as vinyl chloride / vinyl acetate copolymers, polyesters, and urethane resins. However, these dry coating films are often redissolved in a solvent, and the surface strength thereof is inferior to that of the reaction-curing type in many cases. Further, the reaction curable resin includes a heat curable resin, a two-component reactive resin, an ionizing radiation curable resin, and the like. Thermosetting resins include natural oil-modified resins such as amino alkyds and dry oil-modified alkyds, and two-component reactive resins include
There are urethane type resins such as polyester isocyanate and polyether isocyanate which are cured by polyisocyanate.

Examples of the ionizing radiation curable resin include urethane acrylate, polyester acrylate, epoxy acrylate and siloxane which have a polymerizable unsaturated bond in the molecule. The ionizing radiation-curable resin can form a coating film having hardness and excellent scratch resistance and chemical resistance. The topcoat layer composed of these reactive resins can exhibit the characteristics of the coating film by completing the reaction with a dedicated coater having a cured portion. When a large amount of coating is required, the coating can be performed by a method such as reverse coating.

As the matting agent, fine powder of calcium carbonate, barium sulfate, silica, alumina, glass balloon, polyethylene or the like is used. Further, a bead pigment composed of spherical fine particles of resin may be used which is internally colored with a pigment or a dye, if necessary. In particular, for pigments with a matte effect and excellent scratch resistance, iron oxide, titanium oxide, calcium carbonate, quinacridone, and other commonly used pigment fine powders are used as polyurethane, epoxy, acrylic, polyester, nylon, fluororesin, and vinyl chloride. -Resilient resin such as vinyl acetate copolymer, and further dispersed in a composition to which a plasticizer, stabilizer, surfactant and the like are added, if necessary, or coated with these compositions To obtain spherical particles or particles similar to spherical particles. The particle size of the matting agent is 5 to 80 μm, and the particle size is appropriately sieved before use.

The coating liquid for the top coat layer used in the present invention contains two or more kinds of a matting agent having a large particle size distribution and a matting agent having a small particle size distribution, and a large one is similar to the diameter of the concave portion. . And the particle size of the smaller one is
It is preferable to provide the recess not more than ⅓ of the diameter of the recess. A matting agent having a particle size smaller than that of the concave portion is applied to the concave portion and the convex portion, but a matting agent having a larger particle diameter is not deposited in the concave portion,
It is applied only to the convex portion. Therefore, as a whole, the matting agent having a large particle diameter is concentrated on the convex portion and the matting agent having a small particle diameter is concentrated on the concave portion to form a surface design having a different degree of matting.

The top coat layer needs to have a coating amount such that 30 to 80% of the particles of the matting agent are projected on the surface of the topcoat layer.
In the above case, the matting agent cannot be retained in the top coat layer, and the abrasion resistance is impaired. Therefore, the ratio of the matting agent in the coating liquid is 5 to 3 by weight with respect to the binder.
The coating amount is set to 0%, and the coating amount is 10 to 40 g / m ² (solid content conversion, hereinafter, the coating amount in the present specification is calculated and described as the solid content).

[0017]

As described above, the top coat layer containing two or more kinds of matting agents of large and small size provided on the decorative sheet having the concave shape has a high proportion of the matting agent having a small particle size in the concave parts.
Therefore, it acts to increase the degree of matting. And, the convex portion acts so as to increase the proportion of the matting agent having a large particle diameter, and the degree of matting is lower than that of the concave portion,
Therefore, there is an effect that the degree of matting of the convex portions is different. Further, the one using an ionizing radiation curable resin as the binder of the top coat layer has a surface property excellent in chemical resistance and scratch resistance.
