In a substrate coated with a multi-layer decorative and/or protective coating which comprises: (a) a basecoat comprising a pigmented film-forming 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 acid-functional polymer having an average of at least two carboxylic acid groups per molecule wherein the acid-functional polymer is obtained by the half-ester reaction of a hydroxy-functional polymer and at least one cyclic anhydride having one anhydride group per molecule to form acid and ester groups; and (ii) an anhydride-functional compound having an average of at least two cyclic carboxylic acid anhydride groups per molecule; and (iii) an epoxy-functional compound having an average of at least one epoxy group per molecule; and (iv) a hydroxy-functional compound which is different from epoxy functional compound (iii) and which has an average of at least two hydroxyl groups per molecule; wherein at least one of the compounds (i), (ii), (iii) or (iv) comprises a film forming polymer.
