摘要：
An aqueous emulsion which comprises as a resin component a self-emulsifiable copolymer in which at least one ethylenically unsaturated monomer and at least one urethane prepolymer having at least one mercapto group and at least one hydrophilic, polar group are bonded by radical polymerization or in which at least one ethylenically unsaturated monomer, at least one organic polyisocyanate, at least one compound having at least one mercapto group and at least one active hydrogen-containing group and at least one compound having at least one hydrophilic, polar group and at least one active hydrogen-containing group are bonded by urethanization reaction and radical polymerization. The aqueous emulsion is better in storage stability than conventional ones.
