Abstract of the disclosure A two component polyurethane coating consisting of a principal component (A) comprising a hydroxyl group containing film-forming resin, crosslinked polymer particles and a solvent for said film-forming resin, and a hardener component (B) comprising a polyisocyanate compound, which is characterized by using as said crosslinked polymer particles the composite resin particles each comprising a particulate crosslinked polymer core and a number of substantially linear polymer chains coupled with said core in either way of chemical bonding, semi-interpenetration or both of them, the solid weight ratio of said hydroxyl group containing film-forming resin to said composite resin particles being 99/1 to 40/60 and the equivalent ratio of isocyanate groups in the hardener component (B) to hydroxyl groups in the principal component (A) (if the linear polymer chains contain hydroxyl groups, the sum of said hydroxyl groups and those of the hydroxyl group containing film-forming resin) being 0.5 to 2Ø The coating composition is excellent in dispersion stability, application characteristics and drying fastness and capable of resulting an excellent coat.
