摘要： An aqueous urethane resin composition which contains a urethane resin obtained through reaction of 50-90 mass% of an acrylic polyol formed by copolymerization of carbonyl functional group-containing unsaturated monomer, such as diacetone (meth)acrylamide, a hydrophilic group-containing unsaturated monomer, such as a carboxyl group-containing unsaturated monomer, such as (meth)acrylic acid and, optionally, still another unsaturated monomer, such as a carboxyl group containing diol, such as dimethylol-propionic acid, dimethylol-butanoic acid or dimethylol-valeric acid. The acrylic polyol is mixed with 10-50 mass% of polyisocyanate compound forming a film having excellent physical properties such as spread-ability and flexibility; and becomes ambient temperature-curable when combined with a cross-linking agent, such as a hydrazine or a hydrazide compound.
