<P>PROBLEM TO BE SOLVED: To provide a water-dispersible isocyanate composition excellent in water dispersibility and handleability and capable of providing a polyurethane resin composition excellent in water resistance, and an aqueous polyurethane resin composition containing the water-dispersible isocyanate composition. <P>SOLUTION: The water-dispersible isocyanate composition contains a water-dispersible isocyanate obtained from the reaction between: an allophanate-trimmer modified isocyanate obtained from the reaction between a low molecular weight monool and a 1,3-bis(isocyanatomethyl)cyclohexane, and containing an allophanate variant and a trimmer, wherein the content of the allophanate variant to those total weight is 15-75 mass%; and a hydrophilic compound that contains at least one active hydrogen group and a polyoxyethylene unit. <P>COPYRIGHT: (C)2013,JPO&INPIT |
