Self-crosslinking solvent borne pressure sensitive adhesives.

摘要

A pressure sensitive adhesive composition prepared from an organic solvent solution of an interpolymer, the interpolymer containing: i) at least about 80% by weight of at least one alkyl ester of acrylic or methacrylic acid containing 2 to 18 carbon atoms in the alkyl group; or a vinyl ester of an C2-C10 alkanoic acid or combination thereof; ii) 1 to 20% by weight of an ethylenically unsaturated monomer of the general formula: <CHEM> where R1 is H or CH3 with the proviso that (a) when X is NH and R2 is H, R3 is <CHEM> or O-R5 ; (b) when X is NH and R2 is OH; R3 is <CHEM> and (c) when X is O, R2 is H and R3 is <CHEM> where in (a), (b) and (c), R4 is C1-C4 alkyl or (CH2)n and n is 2-4 and R5 is H or C1-C4 alkyl; and iii) 0 to 10% by weight of a hydroxyl containing monomer.
