Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative sheet, which has a deep pattern, but the thickness of the transparent layer between the printed pattern and the base material is particularly thick for the purpose of expressing a sense of depth. However, increasing the thickness of the web for continuous production is undesirable because the winding becomes huge and excessively heavy, and it is also economically inferior. However, when the thickness of the transparent layer is reduced, the sense of depth is reduced, and it is not easy to express a sufficient sense of depth with the thickness of about 0.05 to 0.3 cm, which is the typical thickness for decorative sheets.

Taking these circumstances into consideration, the inventors of the present invention have studied a decorative sheet that can achieve a depth effect without increasing the thickness, and have succeeded in developing a decorative sheet having the structure described in the claims.

The present invention will be explained in detail below using the drawings with p=z.

FIG. 1 is a sectional view showing one embodiment of the present invention.

In Figure j11, the IFi base sheet is shown, 2 is a transparent layer, and 3 is a light-shielding pattern.

゛As the base sheet 1, any material that is normally used as a base sheet for decorative sheets can be used.

Materials for the base sheet (1) include paper such as tissue paper, bleached kraft paper, titanium paper, linter paper, paperboard, and gypsum board paper, polyethylene film, polypropylene film, polyvinyl chloride film, polyhynylidene chloride film, and polyvinyl alcohol. Film, polyethylene terephthalate film, polycarbonate film, nylon film, polystyrene film, ethylene vinyl acetate copolymer film, ethylene vinyl alcohol copolymer film, plastic film or sheet such as ionomer, and metal foil or sheet such as iron, aluminum, copper, etc. , and any combination of the above-mentioned materials can be used. As for the preferable attributes of the base sheet 1, first, it is preferable that the color thereof is high in brightness, or it is also preferable that the surface exhibits metallic luster or pearlescent luster. Reason why a color with high brightness is preferable When the light-shielding pattern 3, which will be described later, casts a shadow on the surface of the base sheet 1 through the transparent layer 2, which will also be described later, it is considered to be rounded so that the shadow can be easily recognized. Therefore, it is of course preferable for the base sheet 1 to be white, but even if it is not white, there is no problem in use as long as it is light in color.Therefore, when manufacturing the base sheet 1, it is preferable to color it with a coloring agent mainly composed of white pigments. It is desirable to apply a paint containing these coloring agents. In addition, when the surface exhibits metallic luster or pearl luster, when the light-shielding pattern 3 casts a shadow on the surface of the base sheet 10 through the transparent layer 2 as described above, the shadow and the area where the shadow does not occur are made clear. Therefore, it is thought that the visibility of shadows is improved. In order to produce metallic luster or pearlescent luster on the surface of the base sheet 1 for this purpose, metal powder or pearl powder (mica is usually used as a substitute) is added to the base sheet 1 when manufacturing the base sheet 1, or It may be manufactured by kneading Fi or applying a paint containing them, or to produce metallic luster, the metal foil or sheet described above may be used as the base sheet l alone or as a composite, or There is no problem in using a suitable metal thin film or a metal layer provided on the surface of the base sheet 10 by plating, or it is also possible to provide a layer exhibiting metallic luster or pearl luster on the back side of the transparent layer. exhibits an effect.

Next, the transparent layer 2 may be formed using a transparent paint or a transparent film or sheet, or may be formed using a transparent paint or a transparent film or sheet. The transparent coating may be made by laminating sheets as appropriate, and the decorative sheet has flexibility, adhesion, and heat resistance or cold resistance during use.

A vehicle selected based on weather resistance and suitability for processing is used. Examples of the vehicle include ethyl cellulose, ethyl hydroxyethyl cellulose, cellulose acetate propionate, nitrocellulose,
Cellulose derivatives such as cellulose acetate, polyprene,
Styrene resins such as polyα-methylstyrene, ethylene copolymer resins, acrylic or methacrylic resins alone or copolymer resins such as polymethyl methacrylate, polyethyl methacrylate, polyethyl acrylate, polybutyl acrylate, rosin, rosin Modified maleic acid resin, rosin modified phenol resin, rosin ester resin such as monopolymerized rosin, polyvinyl acetate resin, coumaron resin, vinyl toluene 111]L vinyl chloride resin, saturated or unsaturated polyester resin, polyurethane resin, butyral resin, polyamide resin , vinyl chloride-vinyl acetate copolymer resin, amino alkyd resin, etc., and in addition to the vehicles mentioned above, color agents for dyes and pigments; plasticizers, stabilizers, surfactants, and waxes.・Additives for grease, desiccants, auxiliary desiccants, curing agents, emulsifiers, thickeners, fillers and dispersants; Add appropriate solvents and diluents and knead them using known coating methods. Gravure coat, cr-ru coat, air knife coat, kiss coat, spray coat, chip coat, dip coat, spinner coat, wheeler coat, brush coat, peta coat by silk screen, wire bar code, flow coat)
4, it can be provided. Further, when a transparent film or sheet is used, the material of the base sheet 1 may be the above-mentioned plastic, black film, or transparent sheet. 5 In the present invention, the term "transparent" in a transparent layer includes not only colorless and transparent but also colored and transparent, and can be used as long as it is transparent and allows the pattern placed underneath to be seen through the transparent layer. In this case, it is also possible to use a material in which metal powder or pearl powder (mica) is added to such an extent that transparency is not lost.In this case, ii) a more complex reflection effect can be obtained. To form the transparent layer 2 using the transparent film or sheet as described above as the transparent layer, the surface y of the base sheet 1 is laminated using an appropriate contact agent, preferably a transparent contact agent. Alternatively, it may be formed by heat fusion, high frequency method, etc. The thickness of the transparent layer is preferably 01wll1 or more, and a thickness of α2 or more gives a noticeable sense of depth.

Next, the light-shielding pattern is formed using an ink with a high pigment content.
Gravure printing, which is a known printing method, is carried out using a layer selected in consideration of weather resistance, etc., and further mixed with the above-mentioned colorants, additives, solvents and diluents as appropriate.
Produced by gravure offset printing, lithographic printing, letterpress printing, intaglio printing, jet printing, silk screen printing, electrostatic printing, etc.

Here, as described in the case of the base sheet 1, it is preferable that the light-shielding pattern is clearly distinguished and the light-shielding pattern is easily recognized, and in that sense, the light-shielding pattern should be white. Most desirable. However, in practice, it is acceptable to use a light color colored with a coloring agent containing white pigment as a living body, and the shape of the light-shielding pattern is not particularly limited, but the shadow cast by the light-shielding pattern on the base sheet can be clearly seen. It is necessary to have an appropriate cutout area so that it can be removed.

As described above, the cosmetic notebook of the present invention essentially consists of a base sheet 1. It consists of a transparent layer 2 and a light-shielding pattern 3, but it also has a layer 4 in Figure 2 for the purpose of reducing surface gloss and improving the physical and chemical properties of the surface, similar to general decorative sheets. A transparent sleeping layer as shown may be provided. As the transparent protective layer 4, a material similar to the above-mentioned transparent layer can be used, but since it directly affects the surface properties of the decorative sheet, it must be selected to have surface properties suitable for the purpose. In addition to the above-mentioned flexibility, heat resistance or cold resistance in use, weather resistance, and processability, abrasion resistance, gloss, surface texture, stain resistance, water resistance,
To adjust the gloss with a transparent protective layer, which preferably has solvent resistance, a known matting agent such as finely powdered silica or calcium carbonate may be added, or surface Kal
Fine irregularities may be imparted by mechanical embossing, and when the transparent protective layer is formed by thermal fusing of a transparent film, surface texture can be imparted and gloss can be adjusted simultaneously with the thermal fusing. Further, when a transparent protective layer is provided, the light-shielding pattern appears to be recessed by the thickness of the transparent protective layer, thereby improving the sense of depth. The surface gloss of the transparent protective layer can be arbitrarily determined, but a glossy surface is preferable to a matte surface since it does not reduce the effects of the present invention.

The decorative sheet of the present invention is formed as described above.

As shown in FIG. 3, for example, the light incident on areas other than the light-shielding horizontal pattern is reflected on the surface of the 5Fi base sheet, and the light 6 incident on the light-shielding pattern area is reflected on the surface of the light-shielding pattern 3. Since shadows are produced on the surface of the base sheet 1 and each shadow is visible, a sense of depth is obtained, creating so-called depth. However, the decorative sheet of the present invention has a depth of 2 and can be obtained by using the decorative sheet alone, and can also be used as a substrate for the decorative board, V, E, various types of plastic, laminated board, wooden base materials such as wooden board, particle board, etc. , gypsum base materials such as gypsum board and gypsum slagnate, pulp cement board 1 asbestos i-ment board, wood chip cement board, etc.) Temporary, G) TC and metal plates such as concrete, iron, aluminum, and gulls, etc. The sense of depth will not be lost even if it is pasted on the screen.

Examples that more specifically illustrate the present invention are listed below.

Example 1 Transparent polyvinyl chloride film (35P) was applied to white polyvinyl chloride film (35PH, R% thickness 0.07M).
After bonding HR, J# (0, 2) with heat fusion properties, flowers were printed on the surface of the transparent polyvinyl chloride film using a white ink containing titanium oxide using a vinyl chloride-vinyl acetate copolymer as a vehicle. Printing was done using a gravure plate that expressed the pattern as a line drawing. The resulting decorative plate had a flower pattern that cast a shadow on the white polyvinyl chloride film that was the base sheet when illuminated, giving it a sense of depth. This embodiment corresponds to FIG.

Example 2 A light yellow colored polyvinyl chloride transparent film (35PHR1 thickness α1) was applied to the printed surface of the decorative sheet obtained in Example 1.
When the intestine was heated under heat, the stain resistance of the surface was as high as that of Example 1.
This is an improvement over the previous decorative sheet, and the sense of depth has also been improved. This embodiment corresponds to FIG. 2.

Example 3 Gravure was applied to the surface of a white polyvinyl chloride film similar to that used in Example 1 using a pearl luster ink made of a vinyl chloride/vinyl acetate copolymer vehicle and kneaded mica strips. Using a peta plate (plate depth 60 μm), a layer exhibiting a pearlescent luster as shown by 7 in FIG.
Similar to ゛, a decorative sheet was created with a transparent white pattern. Since the surface of the base sheet of the obtained decorative sheet 9 had a glossier surface than the decorative sheet V-) obtained in Example 1, the sense of depth was improved.

Example 4 Similarly to Example 2, a pale yellow colored polyvinyl chloride film (thickness 0.1
m, 35 PHR) was subjected to thermal fusion. The resulting decorative sheet had improved surface stain resistance compared to the decorative sheet obtained in Example 3, and an actual example of zero light with improved depth perception corresponds to FIG.

Example 5 Nine thin paper with white peta printing (manufactured by Sanko Paper Co., Ltd., 23F/&
) A transparent pearl paint made of a PVC/vinyl acetate copolymer resin with Kmm parent metal added as a vehicle was roll coated to a thickness of 0.15 mm, and a transparent pearl layer was provided, but the procedure was the same as in Example 1. A decorative sheet was obtained by providing a white pattern. The obtained cosmetic 1\-t had a sense of depth and shine due to the reflection of the mica flakes.

Example 6 A decorative sheet was made in the same manner as in Example 5, except that a colorless transparent layer with a thickness of α15 was provided between the transparent pearl layer and the white pattern using a colorless transparent paint containing a PVC/vinyl acetate copolymer resin as a vehicle. The sheet produced and obtained had deeper depth than the decorative sheet of Example 5.
