Process for forming a pressure sensitive adhesive on a substrate

A process for forming pressure sensitive adhesive on a substrate which comprises

• (1) applying to a substrate a composition comprising
• (A) an organic polymer having at least one reactive silicon-containing group represented by the formula (I):
• ##STR17## wherein R.sup.2 is a monovalent hydrocarbon group having 1 to 20 carbon atoms or a triorganosiloxy group having the formula (II):
• (R').sub.3 SiO-- (II)
• in which each R' is independently a monovalent hydrocarbon group having 1 to 20 carbon atoms, X is hydroxyl group or a hydrolyzable group, and when more than one X is present, each X is independently hydroxyl group or hydrolyzable group, a is 0 or an integer of 1 to 3, b is 0, 1 or 2 and m is 0 or an integer of 1 to 18, wherein said organic polymer is selected from the group consisting of an alkylene oxide polymer having a main chain consisting essentially of recurring units represented by the formula (III):
• --R.sup.1 --O-- (III)
• wherein R.sup.1 is a bivalent hydrocarbon radical having 1 to 8 carbon atoms and an alkyl acrylate polymer, and
• (B) 0.1 to 20 parts by weight of, based on 100 parts by weight of said organic polymer, at least one curing catalyst selected from the group consisting of an organic aluminum and an organic zirconium, and
• (2) curing said composition.
