(57) [Summary] (Modified) SOLUTION: A β-substituted aminocarbonyl phthalocyanine compound represented by the general formula 1, a dye for a filter containing the compound, a filter composition and a filter. [R 1 is hydrogen, a C3-10 branched alkyl group, C3-1 0 branched alkoxyalkyl group, cycloalkyl group, aryl group having a substituent, R 2 represents a C3-10 branched alkyl group, C3-10 branched alkoxyalkyl group, cycloalkyl group, an aryl group having a substituent Further, R 1 and R 2 may be bonded to each other to form a ring of the general formula 2, and Met represents a divalent metal or a trivalent or tetravalent substituted metal or oxymetal. (R 3 represents the same group as R 1. ) [Effect] It is possible to provide a filter having excellent solubility in solvents and binder resins, transmittance characteristics, and durability. |
