## Abstract

A mixed crystal consists of a first metallophthalocyanine compound selected from metallophthalocyanine compounds having at least one trifluoromethyl group and having a central metal selected from the group consisting of cobalt, nickel and copper, and a second metallophthalocyanine compound selected from metallophthalocyanine compounds optionally having at least one substituent group other than trifluoromethyl group and having a central metal selected from the group consisting of cobalt, nickel and copper. The mixed crystal exhibits a peak at 2θ of 5.9 to 6.4° in X-ray diffractometry.

## Claims

### Claim 1

A phthalocyanine pigment comprising a mixed crystal consisting of
a first metallophthalocyanine compound
selected from metallophthalocyanine compounds having at least one trifluoromethyl group and having a central metal Me selected from the group consisting of cobalt, nickel and copper, and
a second metallophthalocyanine compound
selected from metallophthalocyanine compounds optionally having at least one substituent group other than trifluoromethyl group and having a central metal Me selected from the group consisting of cobalt, nickel and copper,
the mixed crystal exhibiting a peak at 2θ of 5.9 to 6.4° in X-ray diffractometry.

### Claim 2 (depends on 1)

The pigment according to claim 1, wherein the first metallophthalocyanine compound and the second metallophthalocyanine compound are present at a molar ratio of 1:0.8-1.2 in the mixed crystal.

### Claim 3 (depends on 1)

The phthalocyanine pigment according to claim 1, wherein the first metallophthalocyanine compound comprises tetra(trifluoromethyl)phthalocyaninatometal, fluoro tetra(trifluoromethyl)phthalocyaninatometal, tri(trifluoromethyl)phthalocyaninatometal, nitro tri(trifluoromethyl)phthalocyaninatometal, methoxy tetra(trifluoromethyl)phthalocyaninatometal, or cyano tetra(trifluoromethyl)phthalocyaninatometal, where the metal denotes cobalt, nickel or copper, and the second metallophthalocyanine compound comprises phthalocyaninatometal, chlorophthalocyaninatometal, tetranitrophthalocyaninatometal, phthalocyaninatometal sulfonic acid, and monochlorotetranitro-phthalocyaninatometal, where the metal denotes cobalt, nickel or copper.
