Polyhalide zinc phthalocyanine, polyhalogenated zinc phthalocyanine pigment and color filter having pixel portion thereof

摘要

It is to provide a polyhalogenated zinc phthalocyanine capable of achieving higher brightness when it is used as a pixel portion of a color filter having excellent coloring power.The polyhalogenated zinc phthalocyanines represented by the following formula 1:X1 to x16Chlorine atom independentlyIs bromine or hydrogen atom.The maximum ionic strength in the mass spectrometry range of M / Z 1780 and aboveThe value obtained by the maximum ion intensity in the range of M / Z 1820 or more isThe above problem is solved by providing a polyhalogenated zinc phthalocyanine characterized by 1.00 or less.
