Abstract:
A polymer composition comprising a film-forming a copolymer formed by polymerization of a monomer mixture comprising:a) at least one monomer selected from the group of monomers consisting of (C1 to C18) alkyl (meth)acrylates, (C5 to C10) cyclo-alkyl (meth)acrylates, styrene, substituted styrene, acrylonitrile, butadiene, isoprene, isobutylene, ethylene, propylene, and vinyl acetate and other vinyl esters of (C1-C12) carboxylic acids, b) 1 to 3% by weight of said monomer mixture of acrylamide, c) at least 1% by weight of said monomer mixture of at least one hydroxy-(C1 to C8)alkyl (meth)acrylate, wherein the total quantity of b) and c) constitutes from 2 to 7.5% by weight of said monomer mixture, andd) 0 or up to 1% by weight of said monomer mixture of at least one polymerizable compound comprising acid groups, wherein said monomer mixture includes no N-vinyl pyrrolidone.
