Abstract

An aqueous styrene-acrylic type polymer dispersion useful as a wet strength adhesive contains at least one copolymer consisting of 0.5 to 5% by weight of N-allylacetoacetamide monomer (A) and 99.5 to 95% by weight of a mixture of monomers (B) consisting of 90 to 99.9% by weight of styrene and of at least one monomer selected from C.sub.1 to C.sub.8 alkyl(meth)acrylates and 10 to 0.1% by weight of at least one monomer selected from acrylic acid, methacrylic acid, acrylamide and methacrylamide.
