Summary:PURPOSE:To obtain polyisocyanate particles which have a high isocyanate group content and are water-dispersible by using a nonaq. dispersion polymn. using a specific dispersion stabilizer and a specific polyethylene oxide deriv. CONSTITUTION:This particles are obtd. by mixing 100 pts.wt. polyisocyanate, a solvent, and a reaction product of 100 pts.wt. unsatd. polyol with 20-400 pts.wt. ethylenically unsatd. monomer having a 2C or higher alkyl group as the side chain and reacting the resulting mixture with 0-100 pts.wt. active hydrogen compd. and 1-20 pts.wt. polyethylene oxide deriv. of the general formula: RO(CH2 CH2O)n(R'O)mH (wherein R is 1-4C alkyl; R' is 3-4C alkylene; n is an integer of 3-120; and m is an integer of 0-10).
