PURPOSE: To obtain the title dispersion with little separation and sedimentation and requiring no defoaming agent by dispersing a plurality of specified compd. in an aq. medium besides a polyisocyanate compd. blocked with an active hydrogen compd. n CONSTITUTION: A compd. (A) of the formula (wherein x is 10-60; y is 0-60; n is 1-3), at least one compd. (B) selected from an alkali metal alkylnaphthalenesulfonate (a), an alkali metal alkyl sulfosuccinate (b), an alkylphenol-ethylene oxide adduct (c) and a higher alcohol-ethylene oxide adduct, an ammonium salt of a partially hydrolyzed polyalkyl acrylate (C) and a polyisocyanate compd. (D) blocked with a compd. having an active hydrogen are dispersed in a medium wherein water is the main component. The obtd. dispersion causes little separation, fixation to the bottom of a container and sedimentation after storage for a long time and little foaming when mixed with an aq. soln. and stirred or squeezed after being applied to woven or knitted fabric and is suitable for paints and adhesives. n COPYRIGHT: (C)1990,JPO&Japio |
