Patent ID: 8258233

Claim:
An aqueous adhesive comprising an aqueous polymer dispersion that comprises a copolymer wherein the copolymer comprises monomer components of: a) 80 to 95 wt. % of vinyl acetate, vinyl propionate, vinyl butyrate or mixtures thereof; b) 1 to 20 wt. % of acrylic acid, methacrylic acid, crotonic acid, itaconic acid, half ester of itaconic acid, maleic acid, half ester of maleic acid, fumaric acid, half esters of fumaric acid or mixtures thereof; c) 0.01 to 5 wt. % of diallyl, divinyl, di(meth)acrylic or tri or tetraunsaturated compounds; d) up to 20 wt. % of α,β-unsaturated esters of C 2 to C 4 mono- or dicarboxylic acids with branched, linear or cyclic C 2 to C 12 alkanols; and e) up to 10 wt. % of copolymerizable monomers that carry polar functional groups; wherein the sum of the components is 100 wt. % and the wt. % ratio of the components c:b is from 1:10 to 1:400.
