Pressure-sensitive adhesive composition

Abstract

Abstract PURPOSE:To provide a pressure-sensitive adhesive composition having excellent pressure-sensitive adhesivity and containing a moisture-curing rubbery organic polymer having reactive silicone functional group, a specific silicone compound and a tackifier resin. CONSTITUTION:The objective composition contains (A) 100pts.(wt.) of a moisture- curing rubbery organic polymer having one or more reactive silicone functional group of formula [R<1> is 1-12C alkyl or aryl; X is OH or hydrolyzable group; (a) is 0-3; (b) is 0-2 1<=a+b<=4; n is 0-19], etc., (preferably an alkoxysilyl group), preferably an alkylene oxide (especially polypropylene oxide (co)polymer, (B) 0.1-50pts. of a compound containing one Si atom having 2 OH or hydrolyzable groups attached thereto and/or a compound having <=1 OH or hydrolyzable group per one Si and containing 2-20 Si atoms having 2-5 OH or hydrolyzable groups in total and (C) 5-120pts. of a takifier resin.
