ε-type copper phthalocyanine pigment, method for producing the same, and coloring composition using the same

摘要

The present invention opens an epsilon type copper phthalocyanine paint, which is provided with the following characters: in the CuK alpha X ray diffraction strength distributing map, set the diffracted intensity value as A when 2 theta=6.8 DEG, set the biggest diffracted intensity value in the scope that the bragg angle 2 theta=9.1DEG+/-0.2DEG as B, and set the minimum diffracted intensity value in the scope that the bragg angle 2 theta=8.6DEG+/-0.2DEG as C when set the line which connects the point of the distribution map that the bragg angle 2 theta=5DEG and the point of the distribution map that the bragg angle 2 theta=12DEG as the zero line, and it satisfies the relation expression -0.05=(A-C)/(A-C+B)= 0.03. The epsilon type copper phtholocyanine paint can be uniformly milled and made using the mixture containing the alpha type copper phthalocyanine, rough epsilon type copper phthalocyanine, water-soluble inorganic salt and the water-soluble organic solvent preferably at the degree from 130 degree to 210 degree in essence. The present invention also opens the dyeing composition containing the epsilon type copper phthalocyanine paint and intermediate medium component.
