Zusammenfassung: | PROBLEM TO BE SOLVED: To improve weatherability, while preventing whitening due to the bleeding of an ultraviolet absorbent, in addition to a feel of coating, a feel of transparency, etc., in simultaneous injection molding with decoration. SOLUTION: In a decorative sheet S, a transparent primer layer 2 containing an acrylic resin as a main component, the ultraviolet absorbent (a) such as benzotriazole, and a hindered amine light stabilizer such as a sebacate radical scavenger as a light stabilizer (b); a decorative layer 3 in which a binder resin contains a mixture of an acrylic resin and a vinyl chloride-vinyl acetate copolymer as a main component; and an adhesive layer 4 using a mixture of an acrylic resin and a vinyl chloride-vinyl acetate copolymer, etc.; are laminated on the back of a transparent base material sheet 1 containing an acrylic resin as a main component, no ultraviolet absorbent, and no light stabilizer (b). A desired decorative molding can be obtained by the simultaneous injection molding with decoration of the decorative sheet. |
