摘要： The present invention relates to a process for production of a water-dispersion of polyurethane resin by an organic acid-oxirane ring opening reaction and to an water-borne paint composition containing the resin made thereby, wherein said a water-dispersion of polyurethane resin is obtained by reacting polyisocyanate and the following polyols: a) A polyol grafted with a long chain alkyl group obtained by organic acid-oxirane ring opening reaction; b) Neutralized dimethyl alkyl acid of 0.1 to 100 milliequivalents and polyethylene glycol of 10 to 2,000 number average molecular weight as functional groups for water-dispersion of synthesized resin. c) Polyol having at least one or more hydroxyl groups on termini and a number average molecular weight of 10 to 2,000. The water-borne paint composition containing a water-dispersion of polyurethane resin, of the present invention, has such advantages as realizing a coating layer of rich gloss, excellence in anti-water and anti-chipping resistance, good storability and effective sprayability.
