AQUEOUS URETHANE RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an aqueous urethane resin composition containing the aqueous urethane resin curable by the irradiation of an active energy beam, capable of securing the stability of sufficient emulsification or dispersion and also having good physical properties after the curing.

SOLUTION: This aqueous urethane resin composition is provided by preparing the aqueous urethane resin curable by the irradiation of the active energy beam by at least reacting a polyisocyanate with a polyoxyethylene side chain-containing diol containing 20 to 95 wt.% polyoxyethylene group in the middle of the branched side chain from the main chain having hydroxy groups at both of terminals and a (meth) acrylate ester containing at least one hydroxy group and blending water with the aqueous urethane resin.
