发明名称 CURABLE RESIN COMPOSITION FOR THERMOFORMING FILM, AND THERMOFORMING FILM MADE BY LAMINATING THE RESIN COMPOSITION
摘要 <P>PROBLEM TO BE SOLVED: To provide a thermoforming film and a laminated product thereof equipped with surface hardness, not causing cracks on the film surface when molded into a deep-drawn shape molding, and excellent in chemical resistance so that the surface of the acrylic film remains free from roughening even when the molding attached with e.g. lotion or hand cream used for sunscreening is exposed as it is for long hours under a high temperature. <P>SOLUTION: This curable resin composition for a thermoforming film contains a vinylic polymer (A) having a carboxy group and a hydroxy group, the acid value of its solid content is 15-150 mg-KOH/g and the hydroxyl value of its solid content is 2-80 mg-KOH/g, and its glass transition temperature is 70-140&deg;C and a polyisocyanate compound (B), where the content of the polyisocyanate compound (B) is one reacting with the 2-80 mg-KOH/g hydroxyl value of the solid content of the vinylic polymer (A). The thermoforming resin film is obtained by laminating the curable resin composition in a thickness of 1-20 &mu;m on one side the thermoforming film as the outermost layer. <P>COPYRIGHT: (C)2012,JPO&INPIT
