Patent ID: 7288595

Claim:
In a curable coating composition comprising: (1) a reactive functional group-containing polymer, and (2) a curing agent having functional groups reactive with the functional groups of (1), but when the reactive function groups of (1) comprise epoxy, the curing agent comprises an aminoplast resin, a polyisocyanate, a blocked isocyanate, a polyepoxide, a polyacid, an anhydride, a polyol, or mixtures thereof, the improvement comprising the inclusion in the coating composition of (3) at least one reaction product of the following reactants: (1) at least one polyoxyalkylene amine selected from the group consisting of polyoxyalkylene monoamine, polyoxyalkylene diamine, polyoxyalkylene triamine, wherein the polyoxyalkylene diamine comprises a compound having the following structure (I): H 2 N[R 1 —O] n [R 3 —O] m —R 2 —NH 2 (I) where R 1 , R 2 , and R 3 can be the same or different and each independently represent a C 2 to C 12 alkylene group, and (n+m) represents a value greater than 2, provided that when R 1 and R 3 are different (n+m) represents a value greater than or equal to 2, and (2) at least one cyclic carbonate wherein the ratio of equivalents of polyoxyalkylene amine (A) to equivalents of cyclic carbonate (B) ranges from 1:0.5 to 1:1.5.
