WATER-RESISTANT ALUMINUM PIGMENT DISPERSION, AQUEOUS INK COMPOSITION CONTAINING THE SAME, AND METHOD FOR PRODUCING WATER-RESISTANT ALUMINUM PIGMENT DISPERSION

摘要

PROBLEM TO BE SOLVED: To provide a water-resistant aluminum pigment dispersion which prevents whitening when blended with aqueous paint or an aqueous ink composition and which has superior water dispersibility and metallic gloss.;SOLUTION: The water-resistant aluminum pigment dispersion is obtained by dispersing a water-resistant aluminum pigment, formed by covering an aluminum pigment with a silica film, in an aqueous solution containing at least one selected from a copolymer A including a structural unit represented by general formula (1) or formula (2) and a structural unit represented by formula (3); a copolymer B including a structural unit represented by the general formula (1) or formula (2) and a structural unit represented by general formula (4); and a copolymer C including a structural unit represented by the general formula (1) or formula (2) and a structural unit represented by general formula (5).;COPYRIGHT: (C)2011,JPO&INPIT
