Problems solved by technology

Specifically, if sufficient weather resistance is to be obtained with benzophenone-based ultraviolet absorbers and benzotriazole-based ultraviolet absorbers, there is a problem that the added amount of ultraviolet absorbers increases and the ultraviolet absorbers tend to bleed out.
In addition, benzophenone-based ultraviolet absorbers and benzotriazole-based ultraviolet absorbers deteriorate greatly with time, making it difficult to maintain weather resistance over a long period of time.

Embodiment 1～14、 comparative example 1～3

[0217] A polypropylene resin sheet (thickness: 60 μm) subjected to double-sided corona discharge treatment was used as a substrate, and a two-component curable acrylic-urethane resin was coated on one surface of the substrate by gravure printing. As a binder, a printing ink containing 30 parts by mass of a colorant relative to 100 parts by mass of the binder resin is provided with a decorative layer (thickness: 3 μm) of a wood grain pattern, and the other surface is coated with two-component curing Type urethane-nitrocellulose mixed resin composition to form a back primer layer (thickness: 3 μm).

[0218] Apply a transparent polyurethane resin adhesive on the decorative layer to form an adhesive layer (thickness after drying: 3 μm), and heat and melt transparent polypropylene resin with a T-die extruder to form a transparent resin layer (thickness: 80 μm).

[0219] Next, after performing corona discharge treatment on the surface of the transparent resin layer, a coating solut...

Embodiment 15

[0262] In Example 1, the base layer was made of a polypropylene-based resin sheet (thickness: 80 μm, crystallinity: 70%, propylene-ethylene random copolymer (ethylene content: 4.5% by mass or less)), and In the same manner as in Example 1, the decorative sheet of Example 15 was obtained.

Embodiment 16

[0264] In Example 1, the base layer was made of a polypropylene resin sheet (thickness: 60 μm, crystallinity: 50%, propylene-ethylene random copolymer (ethylene content: 4.5% by mass or less)), and In the same manner as in Example 1, the decorative sheet of Example 16 was obtained.

Abstract

Provided are: a cosmetic sheet and cosmetic material that can inhibit bleed-out and maintain long-term weather resistance to a very good extent; and a resin composition for a surface protection layer. This cosmetic sheet has at least a base layer and a surface protection layer, wherein the contained amount of an all-ultraviolet absorber in the surface protection layer is 10 parts by mass or less with respect to 100 parts by mass of a resin, and the surface protection layer satisfies [1] or [2]. The present invention also provides a cosmetic material and a resin composition for a protection layer. [1] The surface protection layer contains, as the ultraviolet absorber, a hydroxyphenyl triazine compound represented by general formula (I) and a hydroxyphenyl triazine compound represented by general formula (II), and the contained amount of the hydroxyphenyl triazine compound represented by general formula (II) is 50 mass% or less with respect to a total of 100 mass% of the contained amount of the hydroxyphenyl triazine compound represented by general formula (I) and the contained amount of the hydroxyphenyl triazine compound represented by general formula (II). [2] The surface protection layer contains, as the ultraviolet absorber, the hydroxyphenyl triazine compound represented by general formula (I) and a hydroxyphenyl triazine compound represented by general formula (III).

Description

technical field [0001] The present invention relates to a decorative sheet, a decorative material using the same, and a resin composition for a surface protective layer. Background technique [0002] Conventionally, decorative sheets have been used to decorate or protect interior and exterior members of buildings, interior and exterior members of vehicles such as automobiles, or surfaces of furniture, decoration members, and home appliances. The decorative sheet has, for example, a configuration in which a surface protection layer is provided on a base material layer. [0003] When these decorative sheets are used outdoors, or even indoors, when they are used in a place exposed to sunlight such as a window, the color tone changes and the resin deteriorates due to the influence of ultraviolet rays. Therefore, in order to improve weather resistance, a decorative sheet in which an ultraviolet absorber is added to the decorative sheet has been proposed. [0004] As ultraviolet...
