Beschreibung
Zusammenfassung:	The present invention relates to a coating composition for top coating, comprising an acrylic polyol resin and a polyisocyanate curing agent, wherein the polyisocyanate curing agent is prepared from acuring agent composition containing a polyfunctional isocyanate compound, and the content of unreacted NCO groups in the polyisocyanate curing agent is 10 to 30% by weight relative to the total weight of the curing agent. 本发明涉及面涂用涂料组合物，包括丙烯酸多元醇树脂及多异氰酸酯固化剂，其中，所述多异氰酸酯固化剂由包含多官能异氰酸酯化合物的固化剂组合物而制备，所述多异氰酸酯固化剂中未反应NCO基团的含量相对于固化剂总重量为10至30重量％。
