Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is a decorative sheet used as a decorative wall material for construction or a material for furniture fittings, in particular, reproduces the texture and taste of the material as close as possible. This invention relates to a method for manufacturing a decorative sheet developed for the purpose of.

(Prior art) Conventional decorative sheets are decorative sheets printed with colored patterns or wood-grain decorative sheets with wood-like printing and embossing, and three-dimensional visual effects.
Alternatively, various efforts have been made to give the texture of a cosmetic material, but going through many processes to obtain the material's original texture is expensive in terms of materials and manufacturing costs, so , a decorative sheet with rich material texture is desired.

(Problems to be Solved by the Present Invention) Taking these points into consideration, the present invention aims to provide a method for producing a decorative sheet with a rich texture at a relatively low cost.

(Means for Solving the Problems) In order to achieve this object, the invention according to claim 1 provides a printing ink layer 2 with a wood grain pattern and a base colored ink layer 3 of a pearl solid layer on the back side of a transparent or translucent resin sheet 1. Then, if necessary, a translucent to opaque resin layer 4 is formed on the ink layer side, and then a hairline embossing 5 is applied to the back side of the resin sheet 1 from the ink layer or resin layer side, and finally, an adhesive is applied. Provided is a method for producing a decorative sheet, which is characterized in that a backing material layer 7 such as a colored opaque resin layer or a paper layer having a hiding power is laminated through the wafer.

In addition, the invention of claim 2 forms a printing ink layer 2 with a texture pattern and a base coloring ink layer 3 of a parallel pearl layer on the back surface of the transparent or translucent resin sheet 1, and then, if necessary, makes the resin sheet semitransparent or opaque. The resin layer 4,
After forming on the ink layer side, embossing 5 with rough satin finish or cloth grain etc. is applied to the back side of the resin sheet 1 from the ink layer side or the resin layer side, and finally, with an adhesive, a natural fiber or synthetic fiber etc. Backing material layer 7
To provide a method for producing a decorative sheet, which is characterized by pasting together.

Hereinafter, the manufacturing method according to claim 1 will be explained with reference to the drawings. As shown in FIG. . Next, in order to hide and cover the ink layer 2 and the parts other than the printing ink layer 2, pearl ink is printed solidly as a base color for the wood grain pattern ink layer 2 to form an ink layer 3.

Next, if necessary, a semitransparent to opaque resin layer 4
While solid printing or sheet laminating, a hairline-like embossing process is performed on the back surface of the resin sheet 1 from the ink layer or resin layer side, as shown in FIG. 2, to form an embossing 5.

As shown in FIG. 3, the embossed decorative sheet thus formed is bonded with a colored opaque resin layer or a paper layer with hiding power to the resin layer 4 via an adhesive 6 to form a backing layer 7. It is something to do.

The decorative sheet according to the present invention has a pattern printing ink layer 2 and a base ink layer 3 observed from the sheet surface side.
The color tone and the unevenness of the fine embossing 5 that reflects light by adjusting the reflection angle give the ink layer and the decorative sheet woodgrain pattern a three-dimensional texture with unevenness, and the surface wood texture and fine light reflection. The brilliance of the embossed grains makes the wood stand out even more effectively, giving it a soft and deep wood texture that is not monotonous or flat.

Further, the invention according to claim 2 provides a printing ink layer 2 having a grain pattern on the back surface of the transparent or translucent resin sheet 1.
and a base colored ink layer 3 for the line pearl layer, and if necessary, a semi-transparent to opaque resin layer 4,
After forming this ink layer side by solid printing, or while laminating the resin layer 4, embossing 5 with rough satin finish or silk texture is applied to the back side of the resin sheet 1 from the ink layer or resin layer 4 side,
A backing material layer 7 made of natural fibers or synthetic woven fibers is applied to the back side of the backing material layer 7, and like the earlier wood grain decorative sheet, the texture of the grain of cloth such as silk can be more faithfully expressed in the fiber. It is extremely valuable for its texture and design effect as a decorative sheet.

Furthermore, the decorative sheet according to the invention of claim 2 is as follows:
As shown in FIG. 3, when bonding a backing material layer 7 such as a resin layer, a paper layer, or a fiber layer through an adhesive 6, an embossing plate with a fine matte texture is used to emboss the surface of the transparent resin sheet 1. By applying a pattern, a matte decorative sheet can be obtained, and the surface of the transparent resin sheet 1 can be matted as required.

(Effects) 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 pearl solid layer reflects light at different angles according to the unevenness, and reflects light on that part. The shine of the embossed grains caused by the reflection of light creates a deep, warm and soft textured decorative sheet in the case of wood-grain printed decorative sheets, and the shine of the embossed grains due to the reflection of light, while in the case of cloth-grain printed decorative sheets, the fine texture of silk grains It can express excellent texture and design effects when laminated onto base materials such as plywood and used as interior materials such as architectural wall materials or as materials for furniture and furnishings. .

(Example) On the back of a 0.15 mm transparent vinyl chloride sheet, using gravure ink with salt-vinyl acetate copolymer resin as a binder, a 4-color pattern of Karamatsu straight grain including pearl solid (using a plate with a plate depth of 55 μm) was printed. The pattern was printed in reverse to the normal printing order.

Next, a hairline-like embossing with a depth of 30 to 100 microns is applied to the printed surface, giving the surface a glossy, painted look.
It was possible to obtain a decorative sheet with a three-dimensional effect and an excellent design. Furthermore, in order to reduce the luster on the surface of the decorative sheet obtained in the above example and make it matte, when laminating 100 g/m ² of synthetic resin-impregnated paper as a backing material with adhesive, fine satin-like embossing was applied. An embossed pattern was applied using a printing plate to obtain a matte decorative sheet.

Claims (1)

[Scope of Claims] 1. After forming a printing ink layer 2 with a wood grain pattern on the back side of a transparent or translucent resin sheet 1, a base colored ink layer 3 of a pearl solid layer is formed, and from the ink layer side on the back side of the resin sheet 1, A method for producing a decorative sheet, which comprises applying hairline embossing 5 and finally pasting a backing material layer 7 such as a colored opaque resin layer or paper layer with hiding power through an adhesive. 2 After forming a printing ink layer 2 with a texture pattern on the back side of the transparent or translucent resin sheet 1, a base coloring ink layer 3 of the line pearl layer is formed, and a rough satin finish is formed on the back side of the resin sheet 1 from the ink layer side. Alternatively, a method for producing a decorative sheet is characterized in that embossing 5 such as cloth grain is applied, and finally a backing material layer 7 made of natural fibers or synthetic fibers is bonded together via an adhesive.
