Abstract
Hydroxy-functional esters of substituted imidazolidinediones have the formula: ##STR1## where X is hydrogen, ##STR2## provided both X's are not hydrogen, where R and R' are independently hydrogen or hydrocarbon groups having 1 to 8 carbon atoms, with one Y being hydrogen, one Z being hydrogen and the other Y and Z being ##STR3## where the R' groups are independently hydrocarbon groups having from 1 to 17 carbon atoms. The novel compounds are especially useful when formulated with a crosslinking agent and used in low organic solvent-containing coating compositions.
