INJECTION MOLDING SIMULTANEOUS IN-MOLD DECORATIVE SHEET, INJECTION MOLDING SIMULTANEOUS IN-MOLD DECORATING METHOD AND MOLDED PRODUCT

摘要

PROBLEM TO BE SOLVED: To laminate an in-mold decorative sheet with good bonding properties and heat resistance even for a resin molded product of poor bonding properties such as a polyolefin resin in an injection molding simultaneous decorating method. SOLUTION: In the constitution of an injection molding simultaneous decorative sheet S, a pattern layer 2 containing a mixture of an acrylic resin with a vinyl chloride-vinyl acetate copolymer as a main component of a binder resin and a coloring agent is added therein and a bonding agent layer 3 composed of a thermosetting urethane resin using block isocyanate as a main component are laminated respectively on a transparent base sheet 1 composed of an acrylic resin as a main component. In that case, a primer layer 4 can be formed between the pattern layer and the bonding agent layer. The injection molding simultaneous in-molding decorating is carried out by using the above in-mold decorative sheet to manufacture a molded product.
