A coating composition for producing films having improved scratch and mar characteristics.
The coating composition incorporates a polyester polycarbamate resin composition,
a first cross-linking agent, and a cross-linkable resin to form the film. The resin
composition is the reaction product of a first compound having a plurality of hydroxyl
groups with a carbamate compound reactive with the hydroxyl groups of the first
compound and added in an amount sufficient to form a carbamated intermediary. The
carbamated intermediary has at least one primary carbamate group available for
cross-linking and has unreacted hydroxyl groups. Then, a silyl compound having
a terminal isocyanate group is reacted with the unreacted hydroxyl groups of the
carbamated intermediary. The silyl compound also has silylalkoxy groups available
for secondary cross-linking. The first cross-linking agent and the cross-linkable
resin react with the primary carbamate groups and the silylalkoxy groups, respectively,
to produce the film having improved scratch and mar characteristics.
