Problems solved by technology

Therefore, similar to the above-mentioned Patent Document 1, a problem arises due to bleeding of the silicone-modified resin
[0012] In addition, in the decorative sheet of Patent Document 2, when the surface is wiped, the silicone-modified resin that forms the antifouling layer on the surface is also wiped off at the same time, so it is difficult to maintain the stain resistance for a long time.

Embodiment 1～3

[0141] As a substrate sheet, a polypropylene-based resin film (thickness: 60 μm, transmittance: 10%) was prepared. After corona discharge treatment was applied to the surface and the back surface, a woodgrain pattern layer was formed on the surface by gravure printing. On the other hand, on the back side, an undercoat layer was formed by gravure printing.

[0142] Next, a coating liquid composed of a two-component curing type polyurethane resin was coated on the pattern layer to form an adhesive layer (thickness: 3 μm). Then, a polypropylene-based thermoplastic elastomer composed of an ethylene-propylene-butene copolymer was melt-extruded and coated with a T die to form a transparent resin layer (thickness: 80 μm).

[0143] A two-component curable polyurethane-based resin consisting of acrylic-urethane block polymer (main agent) and hexamethylene diisocyanate (curing agent) is coated on the transparent resin layer to form a primer layer (thickness 2 μm) .

[0144] Next, usi...

Embodiment 4

[0168] A polypropylene-based resin film (thickness: 60 μm, transmittance: 10%) was prepared as a base material sheet. After corona discharge treatment was applied to the surface and the back surface, a woodgrain pattern layer was formed on the surface by gravure printing. On the other hand, an undercoat layer is formed on the back surface by gravure printing.

[0169] Next, a coating liquid composed of a two-component curing type polyurethane resin was coated on the pattern layer to form an adhesive layer (thickness: 3 μm). Then, a polypropylene-based thermoplastic elastomer composed of an ethylene-propylene-butene copolymer was melt-extruded and coated with a T die to form a transparent resin layer (thickness: 80 μm).

[0170] An undercoat layer is formed on the transparent resin layer. The undercoat layer is formed by coating a substance containing 25% by weight of an antistatic agent (quaternary ammonium salt) and 30% by weight of an antistatic agent (barium sulfate) on a...

Abstract

To provide a decorative sheet improved in anti-staining properties along with abrasion resistance and scratch resistance. In the decorative sheet for use in the state laminated on an adherend material, (1) the decorative sheet has at least a base material sheet, a pattern layer, a transparent resin layer, a primer layer and a surface protective layer in succession, (2) the primer layer includes an antistatic agent and (3) the surface protective layer is formed from a composition containing (a) an ionizing radiation polymerizable oligomer, (b) a reactive silicone acrylate and (c) spherical particles with an apparent specific gravity of 0.3-1 g / cm3.

Description

[0001] This case is filed on September 30, 2005 , the application number is 200580033313.6 , the name of the invention is decorative sheet divisional application technical field [0002] The present invention relates to a surface decoration material used as building materials such as furniture and building equipment, a decorative sheet provided with an effective pattern, and a decorative board laminated with the decorative sheet. Background technique [0003] By attaching the decorative sheet to the surface of the attached material, the surface protection and decoration of the attached material such as a wooden board can be achieved. Furthermore, a decorative board obtained by affixing a decorative sheet to an attached material is used for various building materials, furniture, and the like. [0004] The decorative sheet is provided with a surface protection layer for protecting the outermost surface. The surface protective layer must have excellent abrasion resistance,...
