Abstract
A method of producing an article with a color-plus-clear composite coating is described. The method comprises the steps of applying a colored coating composition to a substrate, and applying a clear coating composition over the colored coating composition, wherein the clear coating composition is a curable coating composition comprising: (a) a first component comprising a polymer backbone having appended thereto at least one carbamate functional group, and (b) a second component comprising a compound having a plurality of functional groups that are reactive with said carbamate group.

A method of producing a color-plus-clear composite coating on a substrate comprising the steps of applying a colored coating composition to said substrate, and applying a clear coating composition over the colored coating composition, wherein the clear coating composition is a curable coating composition comprising:
- (a) a first component comprising a polymer backbone having appended thereto at least one carbamate functional group, said first component represented by randomly repeating units according to the formula:
- ##STR4## R.sub.1 represents H or CH.sub.3, R.sub.2 represents H,
- L represents a divalent linking group,
- A represents repeat units derived from one or more ethylenically unsaturated monomers,
- x represents 10 to 90 weight %, and
- y represents 90 to 10 weight %, and
- (b) a second component comprising a compound having a plurality of functional groups that are reactive with said carbamate group.
