1. A pressure-sensitive adhesive composition comprising:
100 parts by mass of a polymer (A) having a glass transition temperature lower than 0° C.; 0.05 parts by mass to 3 parts by mass of a (meth)acrylic polymer (B) having a weight average molecular weight (MWB) of 1000≦MWB<50000 and a glass transition temperature of 30 to 300° C.; and an organopolysiloxane compound (C) having a polyoxyalkylene chain, represented by any one of the following general formulae (C1) to (C3). [In Formula (C1), R1 is a monovalent organic group, each of R2, R3, and R4 is an alkylene group, R5 is a hydrogen or an organic group, each of m and n is an integer of 0 to 1000 (however, they are not 0 at a time), and each of a and b is an integer of 0 to 1000 (however, they are not 0 at a time)]; [In Formula (C2), R1 is a monovalent organic group, each of R2, R3, and R4 is an alkylene group, R5 is a hydrogen or an organic group, m is an integer of 1 to 2000, and each of a and b is an integer of 0 to 1000 (however, they are not 0 at a time)]; and [In Formula (C3), R1 is a monovalent organic group, each of R2, R3, and R4 is an alkylene group, R5 is a hydrogen or an organic group, m is an integer of 1 to 2000, and each of a and b is an integer of 0 to 1000 (however, they are not 0 at a time).] |
