This invention relates to a phosphoric acid group-containing non-aqueous dispersion wherein polymer particles are dispersed in a solution of a macromolecular dispersion stabilizer dissolved in an organic solvent, said polymer particle being a particle of polymer comprising a phosphoric acid group-containing polymerizable unsaturated monomeric unit as a constituent component. With use of said phosphoric acid group-containing non-aqueous dispersion, there can be improved interlayer adhesivity between a metallic coating film, which is formed from a leafing type aluminum flake pigment, and another coating film adjacent thereto, without reducing the excellent effects such as dense metallic feeling of the coated surface, a chrome plating-like finish, and strong brightness feeling and strong flip-flop perperties, which are produced by such a metallic coating film.

Phosphoric acid group-containing non-aqueous dispersion and a process for the application thereof

This invention relates to a method for forming a multi-layer coating film which is characterized by applying a base coating (A) which contains a phosphoric acid group-containing resin composition, and, without curing the same, applying a leafing type aluminum flake pigment-containing metallic composition (B), and, after curing both of said base coating (A) and said metallic composition (B), applying, on the coated surface of said metallic composition (B), a composition (C) which contains a phosphoric acid group-containing non-aqueous dispersion which comprises polymer particles dispersed in a solution of macromolecular dispersion stabilizer dissolved in an organic solvent, said polymer particle being a particle of polymer which is composed of a phosphoric acid group-containing polymerizable unsaturated monomeric unit as a constituent component, and applying a clear coating (D). With use of said method, there can be improved interlayer adhesivity between a metallic coating film, which is formed from a leafing type aluminum flake pigment, and another coating film adjacent thereto, without reducing the excellent effects such as dense metallic feeling of the coated surface, a chrome plating-like finish, and strong brightness feeling and strong flip-flop properties, which are produced by such a metallic coating film.

Method for forming multi-layer coating film

This invention is directed to an aqueous colored coating composition which is applied with a spray device having a fine-orifice nozzle(s), the composition comprising a neutralized acrylic copolymer containing an alkoxysilyl group and a carboxyl group and a coloring pigment.

Aqueous colored coating composition

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)(R.sub.1) (wherein R.sub.1 is a hydroxyl group, a phenyl group or a C.sub.1-20 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.
