Abstract

PURPOSE:To obtain a decorative sheet having excellent designability by applying colored ink in recesses by wiping then providing a transparent resin layer over the entire surface and further forming a transparent matte resin only in the recesses thereon. CONSTITUTION:Colored ink is coated over the entire surface of a synthetic resin sheet 1 having recesses and is scraped away immediately with a doctor blade to form films 2 of the colored ink. Thereafter, a transparent resin layer 4 is formed over the entire surface without filling the recesses. Further transparent matte paint contg. a matting agent such as silica is coated over the entire surface thereon and is immediately scraped away to form films 5 of the transparent matte paint only in the recesses.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wiping decorative sheet, and more particularly to a method for producing a wiping decorative sheet with excellent 4IK design and physical properties. Conventionally, the so-called wiping decorative sheet, which is made by embossing a vinyl chloride sheet or the like and then rubbing a coloring agent into the embossed area, has been used as a high-quality decorative sheet [cabinet parts,
Used for furniture, etc. The present invention relates to a method for manufacturing a wiping decorative sheet that has excellent physical properties in the embossed portion of the wiping soda-containing colored portion and is rich in design.

Conventional wiping decorative sheets are made by applying wiping ink to the entire surface of a vinyl chloride sheet that has been subjected to double-boss processing, then scraping the surface with a doctor blade, rubber roll, etc. to remove excess ink, and applying it only to the concave areas. It left ink behind. At this time, use wiping ink to avoid damaging the surface of the underlying vinyl chloride sheet or printed pattern.
A water-based or alcohol-based ink with low wettability had to be used, and therefore the physical properties of the wiping colored area were weak. Furthermore, when a transparent resin is applied to the entire surface in order to improve physical properties, both concave and convex portions become uniformly glossy, which is unsatisfactory from a design point of view.

The present invention has been made to solve the above problems, and relates to a method for manufacturing a wiping decorative sheet with excellent physical properties in the wiping portion and a high design quality.

The present invention will be described in detail below with reference to the drawings.

First, as shown in Fig. 1, a recess of an arbitrary shape is formed on the surface of a synthetic resin sheet (1) by embossing with pressure, etc.
Colored ink is applied to the entire surface including the recesses and immediately scraped off with a roll, doctor blade, etc. to form a colored ink film (2) only within the recesses. (Hereinafter, this step will be referred to as wiping.) The solvent for the 4114-colored ink used here is water, alcoholic solvent, etc. so as not to significantly dissolve or swell the surface of the synthetic resin sheet (1). It is necessary to select a solvent such as an aliphatic hydrocarbon solvent that has low wetting properties into the synthetic resin sheet.

In addition, when scraping off colored ink with a roll, etc., not only the colored ink attached to the surface of the sheet but also some of the colored ink inside the recesses are scraped off, and the volume of the colored ink is reduced by drying. Therefore, as shown in FIG. 1, the colored ink film (2) does not completely fill the recesses, and therefore the recesses are still formed even after wiping.

□ As the synthetic resin sheet, any synthetic resin sheet that can be embossed can be used, such as a vinyl chloride sheet, a styrene sheet, a polyester sheet, and a polycarbonate sheet.

Next, a colorless transparent or colored transparent resin layer (4) is formed on the entire surface of the sheet on which the colored ink film (2+) has been formed.

The transparent resin layer (4) is made of acrylic urethane, acrylic,
It is formed by applying a transparent resin such as polyester-based or cellulose-based resin, and is formed so as not to fill in the recess 1 where the colored ink coating (2) is formed.

Next, a transparent matte paint containing a matting agent such as silica or polyethylene wax is applied to the entire surface and immediately scraped off to form a film (5) of the transparent matte paint only in the concave portions to form a wiping decorative sheet (6). obtain.

The transparent matte paint used is the aforementioned acrylic urethane type or other transparent resin mixed with a matte agent.

In addition, as shown in Figure 1, any pattern (3) can be applied to the surface of the synthetic resin sheet, and if the pattern harmonizes with the embossed pattern formed by the recesses, it is highly decorative. A decorative sheet is obtained.

The pattern (3) can be applied at any time before forming the recesses, after forming the recesses and before wiping with colored ink, or after wiping with colored ink and before forming the transparent resin layer. . However, if a pattern is applied before wiping, it must be applied using an ink that will not be attacked by the colored ink used for wiping.

The decorative sheet thus obtained has a mattely colored concave portion, and therefore has an extremely rich design and has excellent surface properties.

To summarize the effects of the method of the present invention, since a transparent resin layer is provided on the entire surface of the colored ink coating by wiping, it has excellent physical properties.

Furthermore, since the concave portion is wiped with a matte transparent resin from above, the concave portion becomes matte and has an extremely excellent design.

〔Example〕

After embossing a 0.21111 thick PVC sheet with the oak conduit section, apply water-based oak conduit color wiping ink to the entire surface, immediately scrape it off with a doctor blade, and ink only the conduit section. was left behind. Next, a wood grain pattern of oak wood was printed, and then a transparent acrylic urethane resin was applied to the eating surface and dried.

Next, after applying a water-based acrylic matte transparent paint to the entire surface, it was immediately scraped off with a doctor blade to form a paint film only in the recessed areas. The resulting wiping decorative material has an extremely high design quality because the oak wood conduit portion is colored and matte, and the entire surface is covered with a transparent resin film, so it has excellent physical properties. was.
