PRODUCTION OF POLYURETHANE HYBRID DISPERSION, COATED PREPARATION, ITS PRODUCTION AND COATED MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a polyurethane hybrid dispersion good in gloss, stimulation and hardening rate. ;SOLUTION: This method for producing a polyurethane hybrid dispersion comprises a radical polymerization of at least one kind of a compound having at least one olefinically unsaturated double bond in the presence of at least one kind of polyurethane in a mixture of water and one or more organic solvents, at least one kind of which is the solvent compatible with water, includes no olefinically double bond, has 100°C boiling point and is capable of being removed after radical polymerization.;COPYRIGHT: (C)1998,JPO
