Pigments (used as coloring materials) are aggregates of primary particles. In this condition, they cannot function effectively as coloring materials.
TOKUSHIKI diffuses the solid pigment particles uniformly to the nanometer level during the course of being dissolved into a solution, and can be tailored to a variety of applications and quality requirements.

Coloring agents consisting of particles diffused to the nanometer level make a high purity, high density, and highly permeable mixture. These are widely used in liquid crystal displays, printed circuit boards, and traffic sign boards.
