Abstract: The invention provides composite color-plus-clear coatings having improved appearance, especially with respect to wrinkling, and to methods and compositions for providing such coatings. The method of the invention utilizes a second coating composition comprising (A) a film forming component comprising (a) a first component comprising a compound having appended thereto at least one carbamate or urea functional group, or a group convertible to a carbamate or urea group, and (b) a second component comprising a compound reactive with said carbamate or urea groups on component (a), (B) a cyclic anhydride, and (C) a catalyst.

Abstract: The curable coating composition of the invention comprises a film forming component (A) and a wrinkle reducing catalyst (B) comprising a compound of the formula:M.sub.y (L).sub.xwherein M is a metal having an empty or full d orbital and wherein the pk.sub.a of the aqua ion of M is less than or equal to 12; L is a ligand wherein the pk.sub.a of the parent acid is .gtoreq.-10 and is .ltoreq.4; and x is an integer which is a multiple of the charge of M, y is an interger which is a multiple of the charge of L, x and y selected so that ML is charge balanced. Film forming component (A) has first component (a) with a compound having appended thereto at least one carbamate or urea functional group, or a group convertible to a carbamate or urea group, and a second component (b) with a compound reactive with said carbamate or urea groups on component (a).

Abstract: The invention provides a method for providing a low bake repair to a cured coating, especially a composite coating and low bake repair compositions for use therein. The method of the invention involves the provision of a cured coated surface and the application of a low bake repair coating to at least a portion of the cured coated surface. The low bake repair coating of the invention has (A) a film forming component comprising (a) a first component comprising a compound having appended thereto at least one carbamate or urea functional group, or a group convertible to a carbamate or urea group, and (b) a second component comprising a compound reactive with said carbamate or urea groups on component (a), and (B) a catalyst comprising a compound selected from the group consisting of Al(ClO.sub.4).sub.2, Zr(ClO.sub.4).sub.2, and Al(NO.sub.3).sub.2. The low bake repair coating is cured at a temperature of less than 200.degree. F. for a time sufficient to cure the low bake repair coating.
