COLORING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a coloring composition which colors stably without using a pigment. SOLUTION: The coloring composition is characterized in that the composition comprises a powder dispersed liquid consisting of a liquid phase and the solid phase containing a urethane resin powder, with the above liquid phase having a refractive index of n1 and the above urethane resin having a refractive index of n2 and with the these refractive indices satisfying the equation (1):|n1-n2|<0.05, consequently in that the composition colors on account of the refractive index difference in the interface between the liquid phase and the solid phase.
