2. Description of the Related Art Conventionally, there have been the following techniques for forming fine irregularities on the surface of a molded article, that is, a matte surface called mat. First, a technique for forming fine irregularities on the surface of the transfer target by the transfer sheet will be described. A transfer sheet is formed by forming a transfer layer consisting of a release layer, a pattern layer, and an adhesive layer on a releasable base film, and this technique involves bringing the transfer sheet into contact with another transfer target. , A technique of transferring an adhesive layer, a pattern layer, and a peeling layer in this order to the surface of the transferred material. Therefore, the surface of the transferred material becomes a release layer. Conventionally, in order to form a fine uneven pattern on the surface of such a transferred material, a substrate having a peelable base film on which a fine uneven pattern is formed in advance is used, and a transfer layer is formed thereon. Then, by transferring the transfer layer to the transfer-receiving body and performing the transfer, a fine uneven pattern is transferred to the surface of the transfer-receiving body so that the surface is processed into a matte shape.

Next, a conventional technique for forming fine irregularities on the surface of a molded body will be described. The molded product includes, for example, a decorative plate, which is obtained by impregnating a decorative base paper with a thermosetting resin and drying the core paper, overlay paper,
It is laminated with a substrate film, sandwiched between upper and lower heating plates via a metal mirror plate, and heated and pressed. In such a decorative board, for example, a melamine resin-impregnated paper is laminated on about four phenol resin-impregnated core papers, and an overlay paper impregnated with a melamine resin is further laminated and heat-pressed. There is a melamine decorative board. As another example, diallyl phthalate (hereinafter abbreviated as DAP) resin-impregnated paper is sequentially stacked on a plate-shaped substrate and heated and pressed to form D.
There is an AP decorative board. When imparting fine irregularities to the surface of these decorative plates, between the mirror-finished plate with the fine irregularities formed on the surface, insert a patterning film and sandwich the plate-shaped substrate, and heat press molding Then, it was released from the mold to obtain a decorative plate having fine irregularities on the surface.

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

[0005]

However, the molded article produced by using the conventional patterning film having a fine uneven pattern formed on the surface thereof, which has a matte surface, is touched. The feeling was smooth and rough, and there was no slimy feeling. Further, there is no patterning film having a gloss-mat formed by mixing fine irregularities and flat surfaces on the surface, but only a patterning film having irregularities on the entire surface. The surface appearance of a product transferred or molded using such a shaped film was visually monotonous.

Therefore, the present invention provides a shaped film capable of forming a gloss-mat in which a fine concavo-convex pattern and a flat surface are mixed on the surface of the molded article, and further, the gloss-mat surface of the molded article. The part where the fine uneven layer is formed is moist, has a slimy feel, and is a suede tone, and it is possible to provide a patterning film with a high design effect in which a fine uneven layer and a flat layer can be mixed on the surface. The purpose is to do.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a gloss (matte ant) -matt (matte ant) in which a fine uneven layer and a flat layer are mixed on the surface of a patterning film. (Matte) It is used as an adjustable film. 1 and 2

[0008]

[Equation 1]

The shaped film of the present invention comprises a base film 1
And a surface layer in which the fine concavo-convex layer 2 and the flat layer 3 are laminated on the base film 1. The surface layer of the present invention in which the fine concavo-convex layer 2 and the flat layer 3 coexist is, as shown in FIG. 1, partially coated with resin on the fine concavo-convex layer 2 formed on the entire surface of the base film 1. It is formed by printing. Furthermore, the fine uneven layer 2
Another means of forming a surface layer in which the flat layer 3 and the flat layer 3 are mixed is
As shown in FIG. 2, it is formed by applying a fine concavo-convex layer forming resin composition on the entire surface of the coating film of the liquid-repellent resin partially applied on the base film 1.

A PET film is used as the material of the base film 1, and the fine uneven layer 2 laminated is used as the base film 1.
The base film 1 used in the present invention is subjected to an easy-adhesion treatment so as not to be peeled off. For such an easy-adhesion treatment, a corona discharge treatment, various known primers are applied to the surface of the substrate film 1, or a heat-sensitive adhesive layer is formed.

The fine particles formed on the base film 1
The uneven layer 2 is made of an inorganic filler and a binder resin.
It is formed using a resin composition. That buy
Resin is mainly cross-linked with polyisocyanate
As an inorganic filler using acrylic polyol
Is calcium carbonate CaCO₃And silica gel SiO
₂Is used. Calcium carbonate and silica gel
The addition weight ratio of is from 10:10 to 29: 1.
Calcium carbonate, a mechanical filler, has a particle size of 2-5μ
m, preferably 3 μm. Also, the average of silica gel
The particle size is about 3 times the particle size of calcium carbonate. That
Rica gel is used to adjust the surface roughness of the patterning film.
It works, and calcium carbonate is added without adding silica gel.
If you use only the
And the desired surface cannot be obtained. Also silica
The gel also acts to prevent calcium carbonate from settling.

Examples of the material of the base film 1 of the shaped film of the present invention include polyester resins such as polyethylene terephthalate (PET), polybutylene terephthalate, polyethylene terephthalate-isophthalate copolymer, polyethylene, polypropylene, poly Polyolefin resin such as methylpentene, polyvinyl fluoride, polyvinylidene fluoride, polytetrafluoroethylene,
Polyethylene fluoride such as ethylene-tetrafluoroethylene copolymer, polyamide such as nylon 6, nylon 66, polyvinyl chloride, vinyl chloride-acetic acid copolymer, ethylene-vinyl acetate copolymer, ethylene vinyl alcohol Copolymers, vinyl copolymers such as polyvinyl alcohol and vinylon, cellulosic resins such as cellulose triacetate and cellophane, acrylic resins such as ethyl polymethacrylate and polybutyl acrylate, polystyrene, polycarbonate, polyarylate. , Synthetic resin such as polyimide, or paper such as high-quality paper, thin paper, glassine paper, and sulfuric acid paper.

The slit reverse coating method is used as a method for coating the fine uneven layer 2 on the base film 1. The reason for using this coating method is
This is because the filler particles in the resin composition forming the concavo-convex layer 2 flow like a ring in a usual coating method such as gravure coating, and form streaks on the shaped film. Therefore, in the present invention, the slit reverse coating method, which can form a certain thickness on the coating film, is applied as a coating method so as not to form such streaks. FIG. 4 shows an outline of the slit reverse coat method. The resin composition discharged from the nozzle coating device 4 is applied to the base material film 1 running on the backup roll 6, and then the squeeze roll 5 regulates the film thickness to apply the resin composition.

In the present invention, a release agent is contained in the surface layer of the shaped film of the present invention. It is desirable that the release agent is contained in both the fine uneven layer and the flat layer constituting the surface layer, but it may be contained in either one of them.
The reason for including the mold release agent is to improve the mold releasability from the molded product when the molded product is molded using this pattern-forming film.

Further, according to the present invention, a gloss-mat shaped film in which a fine uneven layer and a flat layer are mixed on the surface is a base film 1 and a fine uneven layer laminated on the base film 1. And a release agent layer formed on this surface layer and a surface layer in which a flat layer is mixed, and a gloss-mat type film. The reason for forming this release agent layer is to improve the releasability from the molded product when the molded product is molded using this pattern-forming film.

As the release agent, silicone, fluorine resin, various waxes, etc. are used. In the present invention, the transfer layer is easily transferred to the transfer target by using the pattern-forming film as the base film 1 of the transfer sheet and incorporating the release agent in the release layer in the base film 1. Considering the compatibility with the binder resin, the release material should be prevented from bleeding too much. If there is a large amount of bleeding on the surface, unevenness will occur in the uneven layer of the patterning film.

In order to eliminate such unevenness, it is important to use a combination having good compatibility with the binder resin for forming the uneven layer. For example, when acrylic polyol is used as the binder resin, amino-modified silicone oil having good compatibility with it is used. Further, if the amount of the release agent added is too small, the peeling will be heavy, and if it is too large, the adhesion between the uneven layer forming resin and the substrate film 1 will be reduced, so that it is 0 to 8% by weight, preferably 0.1 to 5. 5% by weight is good.

Then, a transfer layer is formed on the imprint film of the present invention to form a transfer sheet, and the sheet is brought into contact with the transfer target to transfer the transfer layer to the transfer target, whereby fine irregularities are formed on the surface. Gloss with mixed parts and flat parts
A molded product having a matte surface can be obtained. Moreover, it is possible to obtain a transfer body surface in which the fine irregularities of the molded body have a soft and smooth feel to the touch and are soft and smooth like suede. By the way, as a method for forming a transfer layer on the pattern-forming film and transferring the image on the transfer target, a known method, for example, the method shown in the section of the above-mentioned prior art can be applied.

According to the present invention, the shape-imparting film of the present invention is inserted between the pressure plate and the molded product formed by pressing between the heating pressure plates to form a fine uneven portion and a flat surface. It is possible to obtain a press-molded product having a gloss-matte surface with mixed parts. Examples of such a molded product include a melamine decorative board and a DAP decorative board. In order to produce a melamine decorative board having a gloss-matte surface, about 4 pieces of phenol resin-impregnated core paper are laminated with a melamine resin-impregnated sheet, and an overlay paper impregnated with a melamine resin is further laminated thereon to form 2 sheets of It is sandwiched between mirror-finished metal plates, and the shape-imparting film of the present invention is inserted into the mirror-like metal plate to insert, for example, 100 kg / cm ² , 135
A melamine decorative board having a gloss-matte surface in which fine uneven portions and flat portions are mixed is obtained by performing heat pressing at 20 ° C. for 20 minutes. The fine irregularities give a soft, smooth, suede-like surface to the touch.

A DA having a gloss-matte surface
In order to produce a P decorative board, DAP resin-impregnated paper is sequentially stacked on a plate-shaped substrate, and the shape-imparting film of the present invention is used between mirror-like metal plates in the same manner as in the method for producing a melamine decorative board. 140 to 150 ° C., 15 kg / cm ² , heating and pressing for about 10 minutes to obtain a DAP decorative plate having a gloss-matte surface having a surface in which fine uneven portions and flat portions are mixed. The fine irregularities give a soft, smooth, suede-like surface to the touch.

Further, according to the shaped film of the present invention,
Ionizing radiation curable resin is applied to the surface of the object to be coated, and the patterning film of the present invention is covered therewith to irradiate ionizing radiation such as ultraviolet rays and electron beams to cure the coating film, and then the patterning By peeling off the film, a coated article having a gloss-matt surface in which fine irregularities and flat portions are mixed can be obtained. The uneven portion of the surface of the coated article has a soft and smooth feel to the touch, and is soft and smooth like suede.

Further, in order to make the above-mentioned ionizing radiation-curable coating material into an ultraviolet-curable coating material, acetophenones, benzophenones, Michler benzoyl benzoate, α-amyloxime ester, tetramethyl are used as photopolymerization initiators therein. Thiuram monosulfide, thioxanthone, and n-butylamine, triethylamine, tri-n-butylphosphine and the like can be mixed and used as a photosensitizer. Particularly in the present invention, polyester acrylate to which DAP is added is preferable.

The method for curing these ionizing radiation-curable coating materials can be a usual curing method, that is, a method of irradiating with an electron beam or an ultraviolet ray. For example, in the case of electron beam curing, it is emitted from various electron beam accelerators such as Cockloft-Walton type, Van de Graaff type, resonance transformer type, insulating core transformer type, linear type, dynamitron type and high frequency type.
An electron beam having an energy of up to 1000 KeV, preferably 100 to 300 KeV is used, and in the case of ultraviolet curing, ultra-high pressure mercury lamp, high pressure mercury lamp, low pressure mercury lamp, carbon arc, xenon arc, ultraviolet rays emitted from light rays such as metal halide lamps. Is available.

Furthermore, according to the patterning film of the present invention, a sheet laminated on a substrate film is impregnated with an unsaturated polyester resin liquid, and the patterning film of the present invention is coated thereon and cured. Then, by peeling off the shape-imparting film, it is possible to obtain a press-molded article having a gloss-matte surface in which fine uneven portions and flat portions are mixed. In addition, it is possible to obtain a molded product having a fine textured surface, in which the unevenness has a soft and smooth feel to the touch and is soft and smooth like suede.

Example 1 A silicone-based liquid-repellent resin (Dainichi Seika Kogyo Co., Ltd.) was placed on a PET film (TE, product name, thickness 38 μm, manufactured by Diafoil Co., Ltd.) that had already been subjected to easy adhesion treatment.
(Manufactured by: REP, trade name) was printed by gravure printing, and the pattern layer was partially provided in spots. Next, the resin composition coated on this was prepared as follows. Calcium carbonate CaCO ₃ having a particle size of 3 μ and silica gel SiO ₂ having a particle size of 10 μ were mixed at a weight ratio of 28: 2 to form an inorganic filler. The binder resin was composed of 100 parts by weight of acrylic polyol and 8.5 parts by weight of polyisocyanate. 52 parts by weight of the inorganic filler, 48 parts by weight of the binder resin, and 4 parts by weight of amino-modified silicone oil as a releasing agent were used to prepare a resin composition for forming a fine uneven layer.

One sheet of ultraviolet light of 80 W / cm was irradiated at 20 m / min to obtain a transfer sheet.

Next, using this transfer sheet, ABS
Transfer was performed on the sheet by a hot roll transfer machine to obtain a transfer body having a pattern in which uneven surfaces having a mat-like surface and flat areas having a glossy surface were mixed. The surface of the transfer body thus obtained had exactly the same surface shape as the base film of the transfer sheet used. The Ra of the matte portion on the surface was 1.2 μ, the maximum height difference between the convex portion and the concave portion was 8.0 μm, the average interval between the irregularities was 30 μm, and the average inclination angle of the irregularities was 14 °.

Ra of the matte portion on the surface is 1.2 μ, the maximum height difference between the convex portion and the concave portion is 8.0 μm, and the average interval between the concave and convex portions is 3
It was obtained that the average inclination angle of the unevenness was 0 μm and 14 °. In addition, in Example 6, a polypropylene film was used as the base film for the shaped film for the following reasons. The PET film used in each of the above-described examples absorbs when irradiated with a wavelength region of 365 nm or less, so that there is a defect that curing is insufficient when curing the ultraviolet curable resin coating film. On the other hand, polypropylene film is superior to PET film in transmittance in the wavelength region of 200 nm or more, and a mercury lamp having a wavelength of about 254 nm is usually used for ultraviolet irradiation,
For the curing of the ultraviolet curable resin, it is preferable to use a polypropylene film having excellent transparency at 365 nm.

Then, when the surface of the molded body is shaped, a gloss-matte surface having a high design effect can be formed.

In the uneven layer portion of the patterning film, the average spacing of the unevenness is 20 to 50 μm, the average surface roughness Ra of the unevenness is 0.7 to 2.0 μm, and the 60 ° gloss value of the surface is 2.0 or less. Therefore, the surface of the uneven layer was able to obtain a matte surface with a moist and slimy feel.
This feel was not slippery or shiny, yet unlike the gritty feel, it had a soft, suede-like smoothness, giving it some sort of luxury feel.

In the transfer body or molded product transferred or molded using the shape-imparting film of the present invention, the same surface shape as that of the shape-imparting film of the present invention is transferred, and the feel of the surface is The same feel was obtained.
