Abstract
The present invention provides (i) a novel composition which is the polyol reaction product polyol made by mixing together a polyhydroxyl-tertiary amine, at least two of the hydroxyl groups of said amine being indirectly bonded to a nitrogen atom of said amine through a chain containing at least two carbon atoms, with an organic polyisocyanate, essentially all the isocyanate groups of said polyisocyanate being reacted with hydroxyl groups of said amine, and (ii) a coating composition containing a film forming binder and a volatile organic liquid carrier, said binder containing (I) hydroxyl-containing acrylic polymer and (II) the novel composition (i).
Claims5
