A pressure sensitive adhesive composition which comprises (A) an organic polymer containing a hydrolyzable silyl group which has 1.3 or more pieces o f a hydrolyzable silyl group in one molecule thereof and has a number average molecular weight of 15,000 to 100,000, (B) a an organic polymer containing a hydrolyzable silyl group which has 0.3 to 1.3 pieces of a hydrolyzable silyl group in one molecule thereof, has a number average molecular weight of 500 to 15,000, and has a main chain consisting essentially of a recurring unit represented by the general formula: -R1-O- [wherein R1 represents a divalent alkylene group] and (C) a tackifier resin. The above pressure sensitive adhesive composition can be applied in a state wherein no organic solvent is contained and also exhibits excellent adhesive characteristics. |
