METHOD FOR ELIMINATING WRINKLING IN COMPOSITE COLOR-PLUS-CLEAR COATINGS, AND COMPOSITIONS FOR USE THEREIN |
| 摘要 |
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: My(L)x; wherein M is a metal having an empty or full d orbital and wherein the pk2 of the aqua ion of M is less than or equal to 12; L is a ligand wherein the pka of the parent acid is >/=-10 and is </=4; and x is an integer which is a multiple of the charge of M, y is an integer 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). The method of the invention requires applying a first coating to a substrate; applying a second coating to the first coating to provide a composite coating, the second coating comprising the composition of the invention, and curing the composite coating. |
