<p>PURPOSE:To obtain the subject homogeneous dispersion, capable of preventing segregation and flooding phenomena and useful as a homogeneous colorant which cannot be obtained by combination of individual pigments, by sealing a core substance of an oily pigment containing two or more pigments, a resin and organic solvent in capsules. CONSTITUTION:The objective dispersion obtained by encapsulating a core substance of an oily pigment dispersion containing two or more pigments, a resin and an organic solvent capable of dissolving the above-mentioned resin with a shell formed by interfacial polymerization and, as necessary, blending an aqueous resin dispersion or aqueous solution of a water-soluble resin. Furthermore, the capsules preferably have 0.2-10mum particle diameter.</p> |
