ADHESIVE COMPOSITION, ADHESIVE LAYER, ADHESIVE SHEET, SURFACE PROTECTION SHEET, OPTICAL SURFACE PROTECTION SHEET, AND OPTICAL FILM WITH SURFACE PROTECTION SHEET

摘要

PROBLEM TO BE SOLVED: To provide an adhesive composition that exerts a small adhesive force at high-speed peeling and a high bonding force sufficient enough to prevent a lift or removal at low-speed peeling, the adhesive composition excellent in transparency, and also to provide an adhesive sheet and a surface protective film using the same.;SOLUTION: An adhesive composition contains: 100 pts.mass of a polymer (A) having a glass transformation temperature of less than 0°C; 0.05 to 3 pts.mass of a (meth)acrylic polymer (B) having a weight average molecular weight of 1000 to less than 50000 and a glass-transition temperature of 30 to 300°C; and an organopolysiloxane compound (C) having a polyoxyalkylene chain.;SELECTED DRAWING: None;COPYRIGHT: (C)2017,JPO&INPIT
