Abstract:
1. A pressure-sensitive adhesive composition comprising: (A) 100 parts by weight of a (meth) acrylic copolymer obtainable by copolymerizing (a) 90 to 99.9 parts by weight of a (meth) acrylate ester monomer having an alkyl group having 1 to 12 carbon atoms and (b) 0.1 to 10 parts by weight of at least one of a vinyl monomer and (meth) acrylic monomer each of which contains a crosslinkable functional group, (B) 0.01 to 10 parts by weight of a polyfunctional crosslinking agent, and (C) 0.01 to 9 parts by weight of an organosilicon compound represented by the following formula (3): wherein R is a hydrolyzable group, R′ is an alkyl group having 1 to 4 carbon atoms, A is a linear or branched alkylene group having 1 to 6 carbon atoms, X is an oxygen atom or sulfur atom, Z is —NH—, an oxygen atom or a sulfur atom, R 8 to R 11 are each independently a hydrogen atom, an alkyl, alkoxy or fluoroalkyl group having 1 to 6 carbon atoms, or an amino group, R 9 and R 10 may directly bond together to form a double bond between the carbon atoms to which they are bonded and at the same time R 8 and R 11 may bond together to form an aliphatic or aromatic ring skeleton together with the carbon atoms to which they are bonded, m is an integer of 1 to 3, and n is an integer of 0 to 3.
