SELF-ADHESIVE COMPOSITION, SELF-ADHESIVE SHEET, AND SELF-ADHESIVE LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a self-adhesive composition having high self-adhesive power to an adherend such as metal, short seasoning period and giving a self-adhesive layer extremely low corrosiveness on metal; and to provide a self-adhesive sheet and a self-adhesive laminate made of the same. SOLUTION: The self-adhesive composition includes an acrylic copolymer obtained by polymerization of a monomer composition containing an N-vinyl cyclic lactam monomer and an acrylic monomer and no carboxy-containing monomer, and a polyisocyanate compound. The self-adhesive sheet and the self-adhesive laminate are made of the self-adhesive composition. COPYRIGHT: (C)2010,JPO&INPIT
