Phthalocyanine compound and production method therefor, and coloring composition containing the phthalocyanine compound

摘要

Provided is a phthalocyanine compound which is halogen-free and which has a green hue, excellent resistance to organic solvents and acids, and high chroma. Also provided are a metal-free phthalocyanine compound or a metal phthalocyanine compound represented by specified general formula (1-1) or (1-2) and having a N,N′-disubstituted imidazolone structure or piperazinedione structure introduced therein, and a coloring composition including the compound and a synthetic resin. The phthalocyanine compound of the present invention exhibits a clear green color and is halogen-free, and is thus useful as a clear green pigment for coloring materials such as a coating material, plastic, a printing ink, rubber, leather, textile printing, a color filter, a jet ink, a heat transfer ink, etc.;
