Metallic pigment composition

摘要

Disclosed is a metallic pigment composition which can provide, when used in a coating composition, an ink composition or the like, in particular, a water-based coating, a water-based ink or the like, a coating film having a high storage stability, a good adhesiveness, a good chemical resistance and a good color tone. Specifically disclosed is a metallic pigment composition which comprises at least one kind of compound selected from a heteropolyanion compound and a mixed-ligand heteropolyanion compound, an organic oligomer or polymer, and metal grains.

1. A metallic pigment composition comprising:
metallic particles; 0.01 to 10 parts by weight, based on 100 parts by weight of the metallic particles, of at least one heteropolyanion compound that is at least one selected from the group consisting of H3PWxMo12-xO40.nH2O (phoshotungstomolybdicacid.n-hydrate), H3+xPVxMo12-xO40.nH2O (phosphovanadomolybdic acid.n-hydrate), H4SiWxMo12-xO40.nH2O (silicotungstomolybdic acid.n-hydrate) and H4+xSiVxMo12-xO40.nH2O (silicovanadomolybdic acid.n-hydrate), wherein 1≦x≦11, n≧0; 0.01 to 50 parts by weight, based on 100 parts by weight of the metallic particles, of an organic oligomer or polymer, which is an organic oligomer or polymer having interaction with at least one of the metallic particles and the heteropolyanion compound, which coexist, and is an organic oligomer or polymer that is obtained by performing a polymerization in the presence of the heteropolyanion compound and the metallic particles; and at least one phosphoric acid compound selected from inorganic phosphoric acids or salts thereof.
