Is a wood grain conduit pattern layer, 51 is a colored matte wood grain conduit pattern layer, 52
Indicates a transparent matte wood grain conduit pattern layer, and 53 indicates a transparent matte wood grain conduit pattern layer.

As shown in FIG. 1, basically, the laminated structure of the pattern-tuned decorative sheet of the present invention is, in order from the surface, a wood grain conduit pattern layer 5, a gloss adjusting layer 4, a transparent plastic sheet 1, and a wood grain pattern printing layer 2. , The concealing solid layer 3 is laminated, the gloss adjusting layer 4 is composed of a glossy solid layer 41 or a matte solid layer 42, and the wood grain conduit pattern layer 5 is a colored matte wood grain conduit pattern layer 51 or Transparent matte wood grain conduit pattern layer 52, or colored matte wood grain conduit pattern layer 51 and transparent matte wood grain conduit pattern layer 5
Two layers of 3 may be provided at the same time.

The transparent plastic sheet 1 may be, for example, a synthetic resin film such as a polyvinyl chloride film, a polyolefin resin film, a polyester film, or an acrylic resin film. The polyvinyl chloride film is suitable because of its workability and post-processing such as V-cut, and the thickness of the film is preferably 50 to 300 μm, but in order to give a three-dimensional appearance to the design. , 100μ
It is preferably at least m, especially at least 200 μm.

The transparent plastic sheet 1 includes, for example,
The wood grain pattern print layer 2 that reveals grain of wood such as oak, teak, walnut, cedar, and cypress is a known binder of conventional salt / vinyl acetate type, acrylic type, cellulose type, etc. It is formed by gravure printing with a printing ink using a resin for use, and in order to be able to well express the "shine" of wood grain, it is preferable to add a brilliant pigment such as a pearl pigment or metal powder.

Next, as the concealing solid layer 3, for example, 1
An ink comprising a kneaded product of a known binder resin such as a salt / vinyl acetate type, an acrylic type, a cellulosic type containing a white hiding pigment such as about 0 to 20% by weight of titanium oxide, zinc white, antimony oxide, or the like. It is possible to obtain a solid printing layer by gravure printing by using a coloring ink composed of a kneaded material to which a small amount of another pigment or dye is added. In addition,
It is preferable to use a gravure printing plate having a plate depth of about 35 to 60 μm.

The gloss adjusting layer 4 gives a desirable luster to the surface of the decorative sheet and also serves as a protective layer by covering the surface of the transparent plastic sheet 1. Therefore, a resin having good surface physical properties is used as a vehicle. It is better to use the ink. The resin used as the vehicle is preferably a thermosetting resin such as aminoalkyd resin, urethane resin, unsaturated polyester resin, epoxy resin, acrylic resin, or an ionizing radiation curable resin containing various acrylates.

The ink used in the gloss adjusting layer 4 usually has an appropriate amount of a matting agent dispersed therein to give a desired matting degree, but a gloss type ink containing no matting agent may be used. . Examples of the matting agent used include mica, silica, alumina, calcium carbonate, barium carbonate, diatomaceous earth, silica sand, inorganic hollow bodies such as shirasu balloon, and resin beads.

The gloss adjusting layer 4 is formed by solid-printing the above-mentioned ink by a known means such as gravure coating, roll coating, spray coating or flow coating, and heating or ionizing radiation together with the ink printed thereon as described later. It may be carried out by curing by an appropriate means such as irradiation with.

The surface printing layer of the transparent plastic sheet 1 is preferably a combination of the glossy solid layer 41 or the matte adjusting layer 4 of the matte solid layer 42 and the wood grain conduit pattern layer 5 as described above. The matte solid layer 41 is for making the matte wood grain conduit pattern layers 51, 52 formed thereon stand out, and the matte wood grain conduit pattern layers 51, 52 are the wood pattern pattern on the back surface of the transparent plastic sheet 1. The pattern is formed in synchronization with the print layer 2. When the design has a wood grain pattern, it is formed in a pattern in synchronization with the wood grain pattern conduit part or the spring wood part, and the matte layer 4 has a matteness higher than that of the gloss adjusting layer 4 in order to make it appear as if it is a recess. Use high ink. As the ink to be used, an ink in which a delusterant is dispersed in a vehicle similar to that of the gloss adjusting layer 4 and a color pigment such as carbon black is further added in order to bring it closer to the color tone of the conduit of natural wood may be used.

When expressing a broad-leaved tree having a conduit, such as oak, teak, walnut, etc., as shown in FIG. 2, the gloss adjusting layer 4 is a glossy solid layer 41 and the wood grain conduit pattern layer 5 is a colored matte wood grain conduit. The handle layer 51 may be used,
The colored matte wood grain conduit pattern layer 51 expresses a conduit pattern pattern and is formed so as to be in synchronization with the wood pattern pattern printed layer 2. Since the matte ink layer is formed on the glossy solid layer 41, the contrast between the ink layer and the solid layer becomes conspicuous, and as a result, the conduit pattern portion made of the matte ink layer becomes a recess. It does not require embossing, which makes it look like what you see, and is therefore cumbersome and costly.

When it is desired to express so-called bark (spring material part) such as coniferous trees having different fiber specific gravities, for example, white wood patterns such as cedar and cypress, and fibrous fine irregularities on the surface of wood grain boards, matting without addition of color pigments The wood grain conduit pattern layer may be exposed using transparent ink. That is, as shown in FIG. 3, the gloss adjusting layer 4 is composed of a glossy solid layer 41, and the wood grain conduit pattern layer 5 is composed of a transparent matte wood grain conduit pattern layer 52.

When it is desired to express a wood grain pattern having spots such as spots, tiger spots and the like, which is a fibrous tissue found in a broad-leaved tree having a conduit, the conduit of the wood grain pattern printing layer 2 on the back surface of the transparent plastic sheet is used. The portion to be synchronized is colored with a matte wood grain conduit pattern layer 51 to be a concave portion, and the portion to be synchronized with the spots of the wood grain pattern print layer 2 is transparent and has a glossy wood grain conduit pattern layer 5
It is expressed as 3 in a convex pattern, and the complicated and delicate design of natural wood can be revealed. That is, as shown in FIG. 4, the gloss adjusting layer 4 is a matte solid layer 42, the wood grain conduit pattern layer 5 is a colored matte wood grain conduit pattern layer 51 and a transparent luster wood grain conduit pattern layer 53.
Composed of layers.

Further, as shown in FIG. 5, a glossy solid layer 41 is provided by using a printing plate in which the gloss adjusting layer 4 is synchronized with the wood grain pattern printing layer 2 and the wood grain conduit pattern layer 5 is removed. By forming the conduit pattern layer 5 by printing registration so as to fill the gap of the gloss adjusting layer 4, the matte portion looks relatively concave due to the difference in thickness between the conduit portion and the non-conduit portion and the gloss difference. Although the unevenness of the conduit is better expressed by a synergistic effect with the visual effect, when the gloss adjusting layer 4 is formed,
By manipulating the plate depth to make the thickness of the gloss adjusting layer 4 slightly thicker than the thickness of the ink of the wood grain conduit pattern layer 5, the three-dimensional appearance of the surface can be further enhanced.

Example 1 On the back surface of a transparent polyvinyl chloride film having a thickness of 200 μm, a wood grain pattern of oak grain pattern was printed with a vinyl chloride resin type ink, and then a titanium oxide coated mica type pearl pigment was used.
A luster pattern which is synchronized with the wood grain pattern is printed with a glittering ink containing 1% by weight, and a pattern in which a luster pattern is extracted is printed, and finally a concealing solid layer is printed. Subsequently, the film was inverted using a turn bar, and urethane ink containing 5% by weight of a matting agent as a gloss adjusting ink was solid printed on the surface of the transparent polyvinyl chloride film, and then the matting agent content was 20% by weight.
After printing a pattern synchronized with the matte ink of acrylic black containing carbon black on the wood grain pattern of the conduit, it was heated and cured to obtain a pattern-tuned decorative sheet having an uneven pattern due to the difference in gloss on the surface. .

Example 2 A grain pattern of cedar board pattern was printed on the back surface of a transparent polyvinyl chloride film having a thickness of 200 μm with a vinyl chloride resin type ink, and then 15% by weight of titanium oxide-coated mica type pearl pigment was contained. The luster pattern which is synchronized with the wood grain pattern is printed with the glittering ink to print the pattern, and finally the concealing solid layer is printed. Subsequently, the film was inverted using a turn bar, and urethane ink containing 5% by weight of a matting agent as a gloss adjusting ink was solid printed on the surface of the transparent polyvinyl chloride film, and then the matting agent content was 15% by weight. With a transparent and transparent urethane matte ink, a pattern that is synchronized with the spring grain material pattern of the cedar board pattern is printed, then heated and cured, and the surface has a rough pattern due to the difference in gloss. Got

Example 3 On the back surface of a transparent polyvinyl chloride film having a thickness of 200 μm, a wood grain pattern of an oak grain pattern was printed with a vinyl chloride resin type ink, and then a titanium oxide coated mica type pearl pigment was used.
A luster pattern which is synchronized with the wood grain pattern is printed with a glittering ink containing 1% by weight, and a pattern in which a luster pattern is extracted is printed, and finally a concealing solid layer is printed. Subsequently, the film was inverted using a turn bar, and urethane ink containing 15% by weight of a matting agent as a gloss adjusting ink was solid printed on the surface of the transparent polyvinyl chloride film, and then the matting agent content was 5% by weight.
After printing a pattern that is synchronized with the mottled pattern of oak board pattern with clear and transparent urethane-based glossy ink, the matte agent content is 20% by weight and the acrylic black matte ink containing carbon black is used to create the wood grain pattern. After printing the pattern synchronized with the conduit portion, it was heated and cured to obtain a pattern-tuned decorative sheet having unevenness patterns and spots due to the difference in gloss on the surface.

Example 4 A wood grain pattern of oak grain pattern was printed on a back surface of a transparent polyvinyl chloride film having a thickness of 200 μm with a vinyl chloride resin type ink, and then a titanium oxide-coated mica type pearl pigment was used.
A luster pattern which is synchronized with the wood grain pattern is printed with a glittering ink containing 1% by weight, and a pattern in which a luster pattern is extracted is printed. Subsequently, the film is inverted using a turn bar, and a conduit groove pattern layer having an oak grain pattern is formed on the surface of the transparent polyvinyl chloride film with an acrylic black matte ink containing 20% by weight of a matting agent and carbon black. A pattern is printed in synchronism with the wood-grain-shaped conduit portion using a printing plate from which the conduit groove pattern layer has been removed, and a glossy solid layer is formed using a urethane-based ink containing 5% by weight of a matting agent. After forming a layer with a printing register, it was heated and cured to obtain a pattern-tuned decorative sheet having an uneven pattern due to the difference in gloss on the surface.

[0028]

As described above, the cosmetic composition of the present invention is used.
Since the viewer can feel as if the wood grain conduit handle is a recess, embossing and wiping processes that are troublesome and costly are unnecessary.

Since the wood pattern printed pattern was printed on the back surface of the transparent plastic sheet on which the embossed conduit pattern was formed, both patterns were in good synchronism, and a single layer of the base material sheet was formed between the front and back patterns. Since a thick transparent or semi-transparent layer is provided and the back surface is hidden, a deep expression can be realized based on the difference in the pattern positions on the front and back surfaces, and a natural and complicated delicate state can be reproduced.
