摘要： An unsaturated condensate of an alkoxymethylmelamine, an allylic alcohol and an acrylamide wherein the alkoxymethyl group contains from 1 to 4 carbon atoms, wherein the ratio of allylic moieties to acrylamide moieties is in the range of about 3:1 to about 1:3, wherein there is at least about 0.75 allylic moieties and no more than about 3 acrylamide moieties per melamine ring and wherein the total of allylic moieties and acrylamide moieties is in the range of about 2 to about 4 per melamine ring. The unsaturated condensates are used in high solids unsaturated coating systems containing unsaturated oil-modified resins.

摘要： A fast curing coating composition adapted for use as an automotive topcoat, which upon curing forms a hard, glossy, durable coating exhibiting excellent resistance to solvents and water. The coating composition contains greater than about 55 percent by weight of nonvolatile solids and, exclusive of pigments, solvents and other nonreactive components, consists essentially of:
(A) a copolymer bearing pendent epoxy functionality, and being free of pendent hydroxy functionality, having a number average molecular weight (Mn) of between about 1500 and about 10,000 and a glass transition temperature (Tg) of between about -25° and about 70°C; (B) a reactive catalyst comprising at least one phosphonic acid derivative; (C) an amino resin crosslinking agent; and (D) optionally, a hydroxy functional additive. The phosphonic acid derivative catalyst is included in the composition in an amount sufficient to provide between about .8 and about 1.4 equivalents of acid functionality for each equivalent of pendent epoxy functionality of copolymer (A), and the amino resin crosslinking agent is included in the composition in an amount sufficient to provide at least about 0.4 equivalents of nitrogen crosslinking functionality for each equivalent of hydroxy functionality included in the composition.
