Abstract
PURPOSE:To obtain excellent optical characteristics by fixing a coloring layer with a specific water soluble phthalocyanineazo compd. CONSTITUTION:The coloring layer of a color filter having the coloring layer on a base material surface is fixed by the water soluble phthalocyanineazo compd. expressed by formula I. In formula I, M denotes Cu, Ni, Al-Cl; W denotes an alkali metal, org. amines, ammonium; Pc denotes phthalocyanine skeleton; L denotes formula II, etc.; (k) denotes 1-3, (l) denotes 0-2; (m) denotes 0, 1; (n) denotes 1-3, where k+l+n<=4. In formula II, X denotes a hydrogen atom, SO3W. The coloring layer is thereby colorable (dyeable)) to a green system of the excellent optical characteristics.
