Abstract:
1. A composition comprising a stable aqueous dispersion of acrylic or styrene-acrylic polymer particles imbibed with a thermoplastic step-growth polymer which is a polyhydroxyamino ether, a polyhydroxythiol ether, a polyhydroxyamino ester, a polyester, a polyurethane, a polyurea, or a polysiloxane, with the proviso that when the thermoplastic step-growth polymer is a polyurethane or a polyurea, the step-growth polymer has less than 0.1 percent by weight of acid groups based on the weight of the polyurethane or polyurea and the polymer particles have less than 0.1 by weight of pendant amine groups, based on the weight of imbibed polyurethane or polyurea in the pre-reacted state.
