ABSTRACT:
The invention provides a primary carbamate functional material of the formula:a method of making said materials and curable coating compositions comprising the primary carbamate functional material of the invention. The primary carbamate functional material comprises the reaction product of (1) at least one material P comprising one or more functional groups (i) which are reactive with a functional group Z but which are substantially nonreactive with a primary carbamate group X of monomeric reactive compound (2), and (2) a monomeric reactive compound comprising one or more structures of a particular formula.
