ABSTRACT:
Provided is a curable coating composition comprising a reactive compound having one or more structures of the formula:wherein X is a primary carbamate group, Y is a hydroxy or halide group, n is an integer of 2 or more, n′ is an integer of 1 or more, and R0, R1, R2, R3, R4and R5may be H or a group selected from alkyl groups, aliphatic groups, cycloaliphatic groups, aromatic groups and mixtures thereof, with the provisos that at least one R1or R2group is selected from the group consisting of aliphatic groups, cycloaliphatic groups, aromatic groups, and mixtures thereof, and in substantially all structures primary carbamate group X is attached to a carbon atom having a lower degree of substitution than a carbon atom to which functional group Y is attached.
