The effects of introducing gallium and indium metals into phthalocyanine molecules were investigated via temperature and frequency dependent dielectric spectroscopy. The dielectric properties of Ga(III) and In(III) phthalocyanine pellets were measured at frequencies from 1 kHz to 1 MHz in the temperature range 300-530 K. The temperature dependence of the real part of the dielectric constant suggested that these compounds exhibit semiconductor behavior. The activation energy values were calculated from the Arrhenius plots at different frequencies. A distinct transition in these plots indicated the activation of ionic conductivity at higher temperatures.

Raman spectra of evaporated thin solid films (200 nm thickness) are studied using excitation frequencies in resonance and near resonance with the absorption red band of Al, Ga and in phthalocyanine.Depolarization ratios measured on thin films are also dis

Paragraph 0174, (2017/11/15)
PROBLEM TO BE SOLVED: To provide a phthalocyanine pigment that has excellent fastness (heat resistance, light fastness, solvent resistance) and, when used for a color filter or the like, is excellent in color properties (lightness) and the contrast ratio, without causing unusual matter due to association, aggregation or the like of molecules with each other even in a high temperature environment above 230°C. SOLUTION: The invention provides: a phthalocyanine pigment having a specific structure represented by general formula (1) or the like; and a coloring composition and a color filter using the phthalocyanine pigment.
