Patent ID: 6893718

Claim:
A pressure sensitive adhesive composition 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, R 1 and R 3 independently, are selected from the group consisting of H and C n H 2n+1 , n is an integer ranging from 1 to 5, R 2 is a divalent radical selected from the group consisting of benzeno, substituted benzeno, triazine, C m H 2m , and combinations thereof, m is an integer ranging from 1 to 10, and the 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 0.05.
