Abstract
The present invention relates to a reverse coating process which comprises coating a substrate with a first coating composition containing a fine synthetic resin powder which is solid at a room temperature but can be melted at an elevated temperature, heating the thus obtained coating, electrodeposition coating the coating with an ionic coating composition and subsequently heating the same, the improvement wherein the heating step following the first coating of the substrate with said resin powder-containing coating composition is carried out at a temperature which is high enough to melt the thus formed coating, but not so high to effect cross-linking curing of said coating, and wherein the coating, after said heating or electrodeposition coating step, is subjected to sanding, and the last heating step is carried out at a temperature which is high enough to effect a cross-linking cure reaction in the coating.
