Problems solved by technology

[0005] However, in the conventional decorative sheet, due to heat and pressure during injection molding in insert molding, etc., or during pre-molding (vacuum molding) before injection molding, the concave-convex shape formed by the presence of a transparent resin layer becomes gentle. Or become smaller, so it is easy to damage the high three-dimensional effect of the decorative sheet

[0160] (production of decorative sheets)

[0161] On an ABS resin film (thickness 400 μm) as a base layer, a pattern layer (thickness 5 μm) was formed by gravure printing using an ink containing vinyl chloride-vinyl acetate-acrylic copolymer resin. The pattern of the pattern layer is a wood grain pattern. Next, using a resin composition having a composition described in Table 1, a first protective layer (thickness: 3 μm) was formed on the pattern layer by gravure printing. Next, using the resin composition having the composition shown in Table 1, on the first protective layer, the position of the duct part corresponding to the wood grain pattern of the pattern layer is a non-formed part, and the second pipe part matching the wood grain pattern is placed on the first protective layer. A protective layer (thickness: 3 μm) was formed in a pattern. Next, electron beams were irradiated from the second protective layer side (acceleration voltage 165kV, irradiation dose 50kGy (5Mra...

[0163] (production of decorative sheets)

[0164] On an ABS resin film (thickness 400 μm) as a base layer, a pattern layer (thickness 5 μm) was formed by gravure printing using an ink containing vinyl chloride-vinyl acetate-acrylic copolymer resin. The pattern of the pattern layer is a wood grain pattern. Next, using a resin composition having a composition described in Table 2, a third protective layer (thickness: 3 μm) was formed on the pattern layer by gravure printing. Next, using a resin composition having a composition described in Table 2, a first protective layer (thickness: 3 μm) was formed on the third protective layer by gravure printing. Next, on the first protective layer, using a resin composition having the composition shown in Table 2, the position of the duct part corresponding to the wood grain pattern of the pattern layer is a non-formed part, and the second layer matching the wood grain pattern is placed on the first protective layer.

Abstract

The present invention provides a decorative sheet exhibiting excellent moldability and scratch resistance, and having a good texture, even when molded into a decorative resin molded article. The resin sheet has, in the following order, at least a base layer, a first protective layer, and a second protective layer formed over part of the first protective layer. The first protective layer is formed using an ionizing radiation-curable resin containing a multifunctional polycarbonate (meth)acrylate.

Description

technical field [0001] The present invention relates to a decorative sheet having high formability, scratch resistance, and high three-dimensional effect, a decorative resin molded article using the decorative sheet, and a method for producing the same. Background technique [0002] Conventionally, decorative resin molded products in which a decorative sheet is laminated on the surface of a resin molded product have been used for interior and exterior parts of vehicles, interior materials for building materials, housings of home appliances, and the like. When manufacturing such a decorative resin molded product, a molding method in which a decorative sheet to which a design has been given in advance is integrated with a resin by injection molding is used. As a typical example of a method of manufacturing such a decorative resin molded product, for example, an insert molding method is known. The insert molding method is a method in which a decorative sheet is preliminarily m...
