ABSTRACT:
Curable N-acylurea polymers and coating compositions are provided which cure by reaction of ethylenic unsaturation of the acyl group. The subject polymers are prepared by reaction of a polymeric carbodiimide with an ethylenically unsaturated monocarboxylic acid. Coating compositions so provided may have N-acylurea polymer solids contents of about 30% to about 95% by weight, exclusive of pigment.
