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

摘要

The present invention addresses the problem of providing a polyhalogenated zinc phthalocyanine which has excellent tinctorial power and is capable of producing higher luminance when used in a pixel portion of a color filter. The problem is solved by providing a polyhalogenated zinc phthalocyanine represented by general formula 1 below (in general formula 1, X1-X16 each independently represents a chlorine atom, a bromine atom, or a hydrogen atom), the polyhalogenated zinc phthalocyanine being characterized in that the value obtained by dividing the maximum ion intensity, as measured with mass spectrometry, in the m/z range of 1780 inclusive to 1820 exclusive by the maximum ion intensity in the m/z range of 1820 inclusive to 1860 inclusive is 1.00 or less.
