Abstract
An air drying latex coating composition, curable under ambient conditions, is described having copolymer particles consisting essentially of copolymerized monoethylenically unsaturated monomers dispersed in an aqueous emulsion. The copolymer particles have 0.5-30% by weight of ethylenically unsaturated monomers bonded thereto through reacted C.sub.1 -C.sub.6 N-alkylol functionalities. Curing agents or curing catalysts are also present to cure the deposited composition. The coating compositions are provided by forming an aqueous dispersion of the copolymer particles, bonding an ethylenically unsaturated monomer thereto through a C.sub.1 -C.sub.6 N-alkylol functionality, and admixing therein a curing catalyst or curing agent.
