DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded article having a gloss-matte pattern on the surface formed using a molding film.

[0002]

2. Description of the Related Art Heretofore, there has been a technique described below for forming fine irregularities on a surface of a molded article, that is, a matte surface called a mat. First, a technique for forming fine irregularities on the surface of a transfer-receiving body using a transfer sheet will be described. The transfer sheet is a peelable base film,
Release layer, pattern layer, is formed by forming a transfer layer consisting of an adhesive layer, this transfer technology, the transfer sheet is brought into contact with another transferred object, the adhesive layer, pattern layer on the transferred object surface, This is a technique of transferring in the order of the release layer. Therefore, the outermost surface of the transfer object becomes a release layer. Conventionally, in order to form a fine uneven pattern on the surface of such an object to be transferred, a material having a fine uneven pattern formed on the surface of a peelable substrate film in advance is used, and a transfer layer is formed thereon. And contact the transfer object,
Transcription was being performed. Due to this transfer, the transfer layer having a fine uneven pattern was transferred to the surface of the transfer object, and a mat-like surface was obtained.

Next, a conventional technique for forming fine irregularities on the surface of a molded article will be described. For molded products, for example,
There is a decorative board, which is made by impregnating a decorative base paper with a thermosetting resin and drying it, laminating it with core paper, overlay paper, and base material, and sandwiching this between the upper and lower hot plates via a metal mirror plate. Heat-pressed. Such a decorative board is, for example, a melamine resin impregnated paper obtained by laminating about 4 sheets of phenol resin impregnated core paper on which melamine resin impregnated paper is further impregnated with overlay paper impregnated with melamine resin and heating and pressing. There is a board. As another example, there is a DAP decorative board in which diallyl phthalate (DAP) resin-impregnated paper is sequentially stacked on a plate-shaped base material and heated and pressed. When fine irregularities are to be provided on the surface of these decorative plates, a shaping film is inserted between mirror-like plates having fine irregularities on the surface, the plate-shaped base material is sandwiched, and heated and pressed to form. And then
A decorative plate having fine irregularities on the surface was obtained by releasing the mold.

Further, as another example of a molded article, an ionizing radiation-curable resin is applied to the surface of an object to be coated, and a molding film is covered thereon and irradiated with ionizing radiation to cure the coating. Then, the shaping film was peeled off to obtain an object to be coated having fine irregularities formed on the surface. Furthermore, as another example of the molded product, the imprint film is covered with the one impregnated with the unsaturated polyester resin, the resin is cured, and the imprint film is peeled off to have fine irregularities on the surface. A molded article was obtained.

[0005]

However, in the case of a molded article manufactured using the above-mentioned conventional molding film having a fine uneven pattern formed on the surface, the surface of the molded article was in a mat shape, but was touched. The feeling was slippery and rough, and there was no slimy feeling. Further, by using the shaped film which irregularities are formed on the entire surface, the surface appearance of the transfer, or the molded product were those visually monotonous.

Accordingly, the present invention provides a molded article having a gloss-mat having a high design effect in which a fine uneven pattern and a flat surface are mixed on the surface. The purpose is to provide a moist, slimy, suede-like surface for the uneven portion.

[0007]

Means for Solving the Problems In order to solve the above-mentioned problems, the molded article of the present invention is molded by a gloss-mat preparation film in which a fine uneven layer and a flat layer are mixed on the surface. The fine irregularities layer of the imprinted film has an average interval of irregularities of 20 to 50 μm and an average surface roughness Ra of irregularities of 0.7 to 2.0 μm. By using the shaping film in which the uneven layer and the flat layer are mixed, the touch of the unevenness of the mat portion of the gloss-matte pattern applied to the surface of the molded article has a moist, slimy feeling. A matte surface can be obtained. This feel is not slick or shiny, but unlike the gritty feeling,
It has a soft, suede-like smoothness and some sort of luxury.

[0009]

FIG. 1 is a cross-sectional view of a shaping film used in the present invention. The shaping film used in the present invention is formed of a base film 1 and a surface layer in which fine uneven layers 2 and flat layers 3 are laminated on the base film 1. The fine uneven layer 2 and the flat layer 3
Is formed by partially printing a resin on the fine uneven layer 2 formed on the entire surface of the base film 1. Further, another means for forming the surface layer in which the fine uneven layer 2 and the flat layer 3 are mixed is to cover the entire surface of the liquid-repellent resin coating film partially applied on the base film.
It is formed by applying a resin composition for forming a fine uneven layer (FIG. 2) .

In order to prevent the laminated fine uneven layer from peeling off from the base film using a PET film as a material of the base film, the base film used in the present invention is subjected to an easy adhesion treatment. ing. Such easy adhesion treatment involves applying a corona discharge treatment or various known primers to the film surface, or forming a heat-sensitive adhesive layer.

The fine uneven layer formed on the substrate film is formed using a resin composition comprising an inorganic filler and a binder resin. The binder resin is mainly an acrylic polyol crosslinked with a polyisocyanate, and the fillers are calcium carbonate CaCO ₃ and silica gel SiO ₂ . The addition weight ratio of calcium carbonate to silica gel is 20:10 to 29: 1, and the particle size of the main filler calcium carbonate is 2 to 5 μm, preferably 3 μm.
And The average particle size of silica gel is about three times the particle size of calcium carbonate. The silica gel works to adjust the surface roughness of the imprinted film, and when only calcium carbonate is used without adding silica gel, the obtained surface becomes almost flat, and the above-mentioned object is achieved. No surface is obtained. Silica gel also serves to prevent calcium carbonate from settling.

Examples of the material of the base film of the imprinting film used in the present invention include polyester resins such as polyethylene terephthalate (PET), polybutylene terephthalate, polyethylene terephthalate-isophthalate copolymer, polyethylene, polypropylene, and the like. Polyolefin resins such as polymethylpentene, polyvinyl fluoride, polyvinylidene fluoride, polytetrafluoroethylene, polytetrafluoroethylene resins such as ethylene-tetrafluoroethylene copolymers, polyamides such as nylon 6, nylon 66, Polyvinyl chloride, vinyl chloride-acetic acid copolymer, ethylene-vinyl acetate copolymer, ethylene vinyl alcohol copolymer, polyvinyl alcohol, vinylon,
Such as vinyl copolymers, cellulose triacetate, cellophane,
Cellulose resin such as, polyethyl methacrylate, acrylic resin such as polybutyl acrylate, etc., polystyrene, polycarbonate, polyarylate, polyimide,
Synthetic resin such as high-quality paper, thin paper, glassine paper, parchment paper and the like are used.

The method of applying the fine uneven layer to the substrate film is performed by slit reverse coating. The reason for adopting this coating method is that in the case of a normal coating method such as gravure coating, the filler particles in the resin composition forming the uneven layer flow like a circle,
This is because streaks are formed on the shaping film. Therefore, in the present invention, the coating film can be formed to a certain thickness so as not to form such streaks.
That is obtained by applying by slits reverse coating method. FIG. 4 shows an outline of the slit reverse coat. The resin composition discharged from the nozzle coating device 4 is applied to a sheet-like material running on a backup roll 6 , and then the coating is performed by the squeeze roll 5 with the coating thickness regulated.

Further, the imprinting film used in the present invention contains a release agent in the uneven layer on the surface.
As the release agent, silicone, fluorine resin, various waxes and the like are used. In the present invention, the transfer layer can be easily transferred to the object by using the release film as the base film of the transfer sheet and adding a release agent to the release layer in the base film. The release agent must be designed not to bleed much on the surface in consideration of compatibility with the binder. If there is a large amount of bleed on the surface, unevenness occurs in the uneven layer of the molding film.

In order to eliminate such unevenness, a combination having good compatibility with the binder resin for forming the uneven layer is important. For example, when acrylic polyol is used for the binder, an amino-modified silicone oil having good compatibility with the binder is used. Further, if the amount of the release agent is too small, the peeling becomes heavy, and if the amount is too large, the adhesion between the resin for forming the concavo-convex layer and the base film is reduced.
Preferably, the content is 0.1 to 5% by weight.

Next, an example in which the above-mentioned surface is formed by using a gloss-mat preparation film will be described.
This is to form a transfer layer on the shaping film, contact the shaping film with an object to be transferred, transfer the transfer layer to the object to be transferred, and obtain a molded article having a gloss-matte pattern on the surface. Is what you do. The mat-like portion of the gross-matte pattern of this molded product is formed by the above-described average spacing of the unevenness and the flatness of the unevenness.
Because of the fine irregularities having a uniform surface roughness, it is possible to obtain a soft and smooth suede-like surface of the transfer body with a moist, slimy feel when touched.

Also, the present invention provides a molding film which is inserted between a pressing plate and a molded product formed by pressing between heating and pressing plates to form fine irregularities and flat portions on the surface. It is intended to obtain a press-formed body having a mixed gloss-matte surface. Examples of such a molded body include a melamine decorative board and a DAP decorative board.
In order to produce a melamine decorative board having a gloss-matte surface, a melamine resin-impregnated sheet is laminated on about four phenolic resin-impregnated core papers, and an overlay paper impregnated with the melamine resin is further laminated thereon. Insert the above-mentioned imprinting film having a gloss-matte pattern formed on the surface between the mirror-finished metal plates and insert, for example, 100 kg / c

By peeling off the shaping film, a coated article having a surface in which fine uneven portions and flat portions are mixed is obtained. The unevenness of the surface of the painted product has a soft touch and a smooth, suede-like surface with a soft touch.
The method of interposing an ionizing radiation-curable resin between the shaping film and the base material includes applying the ionizing radiation-curable resin to the base material surface in advance, and covering the applied surface with the shaping film, or This is performed by covering the application surface of the shaping film coated with the ionizing radiation curable resin so as to face the substrate surface.
