Acrylic oligomeric and polymeric durability enhancing agents, method therefore and cured coating compositions containing the same

A coating composition comprising

• a) oligomers and polymers having thereon, a reactive functionally capable of undergoing a crosslinking reaction, wherein the reactive functionality comprises at least one functional group selected from the group consisting of primary carbamate groups, and functional groups convertible to primary carbamate groups, said oligomers having a weight average molecular weight of less than or equal to 2000 and said polymers having a molecular weight of greater than 2000, and mixtures of said polymers and oligomers,
• b) a crosslinking agent having more than one functional group reactive with the carbamate functionality on component (a),
• wherein component a) further comprises at least one ultraviolet light absorbing compound or hindered amine light stabilizer grafted onto component (a), wherein a crosslinked film formed from the cured coating composition demonstrates etch resistance and gloss retention.
