Provided is a metallic-pigment composition which is usable in coating compositions or ink compositions, in particular, in water-based coating compositions or aqueous inks, and which gives coating compositions having excellent storage stability. The metallic-pigment composition gives a coating film having excellent performances with respect to brightness, hiding properties, flip-flop feeling, etc., causes no colorant or organic-pigment discoloration, and has excellent adhesion and chemical resistance. The metallic-pigment composition comprises one or more mixed-coordination-type heteropolyanion compounds, a hydrolyzate of a silicon compound and/or a condensate thereof, and metal particles.
本发明提供了一种金属颜料组合物,它可用于涂料组合物或油墨组合物,特别是用于水基涂料组合物或水性油墨,并使涂料组合物具有优异的储存稳定性。该金属颜料组合物所制成的涂膜在亮度、遮盖力、翻转感等方面性能优异,不会导致着色剂或有机颜料变色,并具有出色的附着力和耐化学性。金属颜料组合物由一种或多种混合配位型杂多阳离子化合物、硅化合物的水解物和/或其缩合物以及金属颗粒组成。
