METAL-FREE PHTHALOCYANINE HAVING NOVEL CRYSTAL TYPE AND COLORING COMPOSITION USING THE METAL-FREE PHTHALOCYANINE

摘要

PROBLEM TO BE SOLVED: To provide a high chroma metal-free phthalocyanine pigment and a coloring composition using the pigment.;SOLUTION: The above described problem is solved by a metal-free phthalocyanine pigment having a novel crystal type having diffraction peaks at diffraction angle (2θ±0.2 degree) to an X ray of CuKα of 7.4, 9.0, 13.6, 16.7, 17.1, 20.1, 20.7, 22.0, 23.8, 27.3 and 28.4, and a coloring composition containing the pigment and a resin.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
