Title:
SOLID SOLUTION PIGMENT NANOPARTICLES
Document Type and Number:
Japanese Patent JP2012126893
Kind Code:
A
Abstract:

To provide solid solution pigment nanoparticles having a homogeneous solid-solution ratio.

The solid solution pigment nanoparticles are produced by mixing at least one kind of a pigment solution obtained by dissolving at least two kinds of pigments into a solvent, or at least two kinds of pigment solutions obtained by dissolving at least one kind of pigment into a solvent, with a solvent for depositing the pigments, to thereby deposit at least two kinds of pigments. In the solid solution pigment nanoparticles, a solid-solution ratio of at least two kinds of pigments in primary particles of the deposited solid solution pigment nanoparticles to the ratio of at least two kinds of pigments in the pigment solution mixed with the solvent for depositing the pigment has a precision of ≤25%.
