COLORED MICROPARTICLES, AND AQUEOUS DISPERSION CONTAINING THE COLORED MICROPARTICLES

摘要

PROBLEM TO BE SOLVED: To provide colored microparticles, as a coloring material to be used as a precursor for inkjet recording ink or as a dispersion of the coloring material, which are excellent in the color developing properties, transparency and glossy feeling of a printed matter, which give an image excellent in the image fastness such as the light resistance, the water resistance and the fixing property, and which are excellent in the storage stability and at the time of preparing ink and also which is excellent in the discharge stability without clogging in head at the time of printing, and to provide an aqueous dispersion containing the colored microparticles.;SOLUTION: The colored microparticles comprise oily dyestuff microparticles in a resin, and are characterized in that the above oily dyestuff microparticles have an average particle diameter of 100 nm or less and the colored microparticles have an average particle diameter of 150 nm or less.;COPYRIGHT: (C)2008,JPO&INPIT
