PURPOSE: To improve a preservable property by incorporating titanyl phthalocyanine having a peak at a specific Bragg angle in X-ray diffraction spectra and a specific multilayered type phthalocyanine deriv. into the above coating liquid.
CONSTITUTION: The multilayered type phthalocyanine deriv. expressed by formula I or II is incorporated into the titanyl phthalocyanine having the peak at 27.2±0.2° of the Bragg angle 2θ in one diffraction pattern to the characteristic X-ray (1.541) of the CuKα ray, more preferably the titanyl phthalocyanine dispersion having the peaks at 9.5±0.2, 24.1±0.2° and 27.2±0.2° of the Bragg angle 2θ. In the formulas I, II, M1 denotes a quadrivalent metal atom; M2 denotes a trivalent metal atom; X1 to X4 denote a hydrogen atom, etc.; Y denotes an oxygen atom or sulfur atom; Z denotes a residual org. group; p, q, r, s denote an integer from 0 to 4; n denotes an integer ≥0. The preservable property is improved in this way.
