| abstract |
An object of the present invention is to provide a dye excellent in durability. A merocyanine dye represented by the following general formula (1). (In the general formula (1), R 1 represents an alkyl group, an aralkyl group, an alkenyl group, an aryl group, or a hetero ring, and may have a substituent. R 2 represents an alkyl group, an alkoxy group, or a halogen atom. R 3 and R 4 each represent a hydrogen atom, an alkyl group, an alkoxy group, an alkylthio group, an aryl group, an aryloxy group, an arylthio group, or a hetero ring, and have a substituent. R 5 represents a substituent having an acidic group, X 1 represents a linking group forming a cyclic structure together with an amino group, m represents 0 or 1. The carbon-carbon double bond is represented by E Type or Z type.) [Selection diagram] None |
