Description

[Detailed Description of the Invention] The present invention was developed with the aim of reproducing as closely as possible the texture and taste of decorative sheets used for architectural wall decorative materials or furniture fitting materials, especially materials. Regarding decorative sheets.

Conventional decorative sheets are decorative sheets printed with colored patterns or wood grain printed decorative sheets printed and embossed with a wood texture to give an uneven three-dimensional visual effect or texture as a decorative material. Although various efforts have been made, obtaining the original texture of the material is expensive in terms of materials and manufacturing costs, so there is a desire for a decorative sheet that is inexpensive and has a rich texture.

The present invention is a decorative sheet manufactured with these points in mind, which is relatively inexpensive and has a rich texture.

The present invention provides a printing ink layer 2 with a wood grain pattern or cloth grain pattern on the back side of a transparent or translucent resin sheet 1.
and a base colored ink layer 3 for the pearl solid layer, and if necessary, a semi-transparent to opaque resin layer 4,
After forming on the ink layer side, it is a decorative sheet in which hairline embossing, or embossing 5 of rough satin finish or cloth grain, etc. is applied to the back side of the resin sheet 1 from the ink layer or resin layer 4 side, and furthermore, the resin layer 4 is formed on the ink layer side. A two-layer or three-layer backing material 7 made of a thermoplastic resin sheet laminated on one or both sides of a nonwoven fabric is attached to the side using an adhesive 6.

The present invention will be explained in detail below with reference to the drawings.
As shown in FIG. 1, first, a wood grain pattern or a cloth grain pattern is printed on the back side of a transparent or translucent resin sheet 1 to obtain an ink layer 2. Next, ink layer 2 and ink layer 2
In order to cover the other parts, pearl ink is printed solidly as a base color for ink layer 2.
A base colored ink layer 3 is formed. Note that this solid pattern includes a line-shaped solid pattern. Furthermore, after forming a translucent to opaque resin layer 4 on the base colored ink layer 3 side as necessary, as shown in FIG. In the case of a cloth grain pattern, an embossing 5 of rough satin finish or cloth grain is applied. Next, as shown in FIG. 3, a backing material 7 made by laminating a thermoplastic resin sheet 9 on one or both sides of a nonwoven fabric 8 is attached to the embossed surface via an adhesive 6 to obtain a decorative sheet. .

In the case of a decorative sheet obtained by the present invention, in the case of a wood grain pattern, the color tone of the printing ink layer 2 and the base colored ink layer 3 observed from the sheet surface side, and the unevenness of the fine embossing 5 that reflects light, It gives an uneven, three-dimensional texture to the wood grain pattern of the ink layer and decorative sheet, and can further effectively enhance the surface wood texture with the brilliance of the embossed grains that reflect fine light. It gives a soft and deep wood texture that is not monotonous and flat, and in the case of cloth grain patterns, it is possible to more faithfully express the texture of cloth such as silk in the fiber. It is extremely valuable as a decorative sheet due to its texture and design effect.

The backing material 7 is made by laminating a thermoplastic resin sheet 9 such as a vinyl chloride sheet or a polyethylene sheet on one or both sides of a nonwoven fabric 8. When laminated only on one side, the backing material 7 is made by laminating a thermoplastic resin sheet 9 such as a vinyl chloride sheet or a polyethylene sheet on one or both sides of the nonwoven fabric 8. The sheets may be laminated with the surface facing the embossed surface, or the surface of the thermoplastic resin sheet 9 may be laminated with the surface facing the embossed surface as shown in FIG.

In addition, as for the method of lamination, whether it is on one side or both sides, it may be laminated with an adhesive, or it may be laminated while forming a resin film on the surface of the nonwoven fabric by extruder coating. . Moreover, in the case of both sides, it is also possible to adopt a method of heat fusing.

As the nonwoven fabric, glass nonwoven fabric, polyester nonwoven fabric, or other materials with good heat resistance are used. The degree of heat resistance may be such that dimensional changes do not occur during the process of laminating it to the back side of the resin sheet or during the process of using it as a decorative sheet, that is, as a product.

In addition, a matte decorative sheet can be obtained by applying an emboss pattern on the surface of the transparent or semi-transparent resin sheet 1 using a fine satin-like embossing plate as necessary, and the embossing is applied in a separate process. Alternatively, it may be applied at the same time as the backing material is laminated.

According to the present invention, since the colored pearl solid layer, which is the base ink layer, has an embossed uneven pattern such as hair lines, the embossed pattern shines due to the reflection of light in that area, and in the case of a wood grain printed decorative sheet,
A richly textured decorative sheet with depth and warm softness can be obtained, and the textured decorative sheet can express the delicate texture of silk grain, and can be laminated to a base material such as plywood for construction purposes. It exhibits excellent texture and design effects when used as an interior material such as a wall surface material or as a material for making furniture. Furthermore, since a nonwoven fabric is used as the backing material, it is possible to obtain an embossed decorative sheet that is excellent in dimensional stability, reduction in discoloration, and the like.

<Example> On the back of a transparent vinyl chloride sheet with a thickness of 0.15 m/m,
Using gravure ink with salt-vinyl acetate copolymer resin as a binder, we printed a four-color Karamatsu straight-grain pattern including pearl solids (plate depth 55μ) and colored transparent solids (plate depth 55μ) in reverse of the normal printing order. It was printed by printing.
Next, the printing surface is embossed in a hairline shape with a depth of 30 to 100μ, and a backing material is made by laminating a 0.15 m/m thick vinyl chloride sheet on both sides of the glass nonwoven fabric on the embossed surface by heat fusion. By laminating them together with an adhesive, we were able to obtain a decorative sheet with a glossy surface, a painted feel, and a three-dimensional effect that was excellent in terms of design. Furthermore, in order to reduce the luster on the surface of the decorative sheet and make it matte, when laminating the backing material, an embossed pattern was applied using a fine satin-like embossing plate to obtain a matte decorative sheet.
