Abstract

Abstract The present invention provide a novel coating method for forming a metallic coat having excellent appearance. The coating method comprises the successive steps of: (a) coating an article with an sealercoating composition, (b) coating the sealercoated article with an aqueous metallic basecoating composition without curing the sealercoating composition, (c) flashing and/or baking the article obtained in Step (b), (d) coating the article obtained in Step (c) with a thermosetting clear coating composition, and, (e) baking the coated article.

Claims Analysis

Total Claims: 15
Claim 1
Independent Claim 85 words
A coating method for forming a metallic coat comprising the successive steps of: (a) coating an article with an electrocating composition and baking it, (b) coating the thus-baked article with a sealer coating composition, (c) coating the sealer coated article with an aqueous metallic base coating resinous composition without curing the sealer coating composition, (d) flashing and/or baking the article obtained in Step (c), (e) coating the article obtained in Step (d) with a thermosetting clear coating resinous composition, and, (f) baking the coated article.
Claim 2
Dependent Claim 85 words
A coating method for forming a metallic coat comprising the successive steps of: (a) coating an article with an electrocating composition and baking it, (b) coating the thus-baked article with a sealer coating composition, (c) coating the sealer coated article with an aqueous metallic base coating resinous composition without curing the sealer coating composition, (d) flashing and/or baking the article obtained in Step (c), (e) coating the article obtained in Step (d) with a thermosetting clear coating resinous composition, and, (f) baking the coated article.
