1. A photosensitizer that is a dye represented by the following general formula (I) or its salt:(In formula (I), m represents an integer of 0 through 4, and n represents an integer of 0 or 1, and p represents an integer of 0 to 2. R1 and R2 represent a hydrogen atom, an alkyl group or an aryl group, and may bind to each other to form an aromatic ring or an aliphatic ring. R3 represents an alkyl group, an aryl group, an aralkyl group or a heterocyclic residue. R4, R4′ and R4″ represent a hydrogen atom, an alkyl group, an aralkyl group, an alkoxy group, a substituted amino group or a halogen atom, and may bind at R4′ and R4″ to form a ring structure. R5 and R6 represent a hydrogen atom, an alkyl group, an alkoxy group or an alkylthio group, and may bind at R5 and R6 to form a ring structure. R7, R8 and R9 represent a hydrogen atom, an alkyl group, an aralkyl group, an alkenyl group or an aryl group, and may bind at R7 and R8, or at R8 and R9 to form an aliphatic ring. X represents an oxygen atom, an alkylene group, or a carbonyl group. Z1 and Z2 represent a hydrogen atom, a hydroxyl group, a carboxyl group, an alkoxycarbonyl group, a sulfone group or a substituted amino group, but Z1 and Z2 are hydrogen atoms not at the same time. Here, an acidic group is included as at least one substituent in a molecule). |
