Method for formation of coating film

摘要

The present invention provides a method for forming a multi-layer coating film by applying a colored clear coating (B) containing a color pigment and/or a glittering material, on the film of a leafing type aluminum flake-containing metallic coating (A), wherein the colored clear coating (B) also contains a polymer formed from an unsaturated monomer having a phosphoric acid group represented by -O-PO(OH)(R1) (wherein R1 is a hydroxyl group, a phenyl group or a C1-20 alkyl group) and a hydroxyl group-containing unsaturated monomer. The method can form a multi-layer coating film improved in interlayer adhesivity between the metallic coating film and the colored clear coating film, without reducing the excellent effects and metallic feeling provided by a metallic coating film containing leafing type aluminum flake.
