    摘要： 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.
