Substrate coated with a clearcoat/basecoat composition comprising an anhydride-functional compound and an hydroxy-functional compound

In a substrate coated with a multi-layer decorative and/or protective coating which comprises:

• (a) a basecoat comprising a pigmented film-fomring polymer;
• and
• (b) a transparent clearcoat comprising a film-forming polymer applied to the surface of the basecoat composition;
• the improvement which comprises utilizing as the clearcoat and/or the basecoat a multicomponent curable composition which is reactive upon mixing of the components, wherein the curable composition comprises:
• (i) an anhydride-functional polymer which is the addition polymerization reaction product of (a) 5 to 40 weight percent of an ethylenically unsaturated monoanhydride and (b) 60 to 95 weight percent of at least one other ethylenically unsaturated monomer copolymerizable with the ethylenically unsaturated anhydride;
• and
• (ii) a hydroxy-functional polymer which is the addition polymerization reaction product of (a) 10 to about 40 weight percent of a hydoxy-functional ethylenically unsaturated monomer and (b) 60 to about 90 weight percent of at least one ethylenically unsaturated monomer copolymerizable with the hydroxy-functional monomer.
