ABSTRACT:
A pressure sensitive adhesive composition is described, comprising the reaction product of a copolymer and a bisamide crosslinking agent, (A) the copolymer comprising the reaction product of (i) a (meth)acrylate ester of a non-tertiary alcohol in which the alkyl group contains between 1 and 4 carbon atoms, inclusive, and (ii) a carboxylic acid-functional, ethylenically unsaturated co-monomer, and (B) a bisamide crosslinking agent having the formula:where,R1and R3independently, are selected from the group consisting of H and CnH2n+1,n is an integer ranging from 1 to 5,R2is a divalent radical selected from the group consisting of benzeno (—C6H4—), substituted benzeno, triazine, CmH2m, and combinations thereof,m is an integer ranging from 1 to 10, andthe relative amounts of the carboxylic acid-functional, ethylenically unsaturated co-monomer and the bisamide crosslinking agent providing a ratio of the number of equivalents of amide groups to the number of equivalents of carboxylic acid groups of less than about 0.1. Articles made with the pressure sensitive adhesive composition and methods for its use are also described.
