Aqueous urethane resin compositions
摘要:
This invention offers an aqueous urethane resin composition which contains a urethane resin obtained through reaction of acrylic polyol formed by copolymerization of carbonyl functional group-containing unsaturated monomer, hydrophilic group-containing unsaturated monomer and, where necessary, still other unsaturated monomer; with polyisocyanate compound and, where necessary, carboxyl group-containing diol; can form film of excellent physical properties such as spreadability and flexibility; and becomes ambient temperature-curable when combined with a crosslinking agent.
