PURPOSE:To obtain a charge generating material which forms carriers with visible light and has excellent film formability by providing a specific rhodanine drive. regularly to the side chain of a chain high polymer. CONSTITUTION:The rhodanine deriv. expressed by the formula I is provided regularly in the side chain of the chain high polymer. In the formula I, R1 denotes a lower alkyl group of 1-6C, substd. or unsubstd. aryl group, hydrogen atom, hydroxyl group. The polymer which generates the carriers with the visible light has the rhodanine ring in the molecular chain and a quinoline group intro duced via a 2-butyl diiridene group in the 5-place of the rhodanine ring. This polymer, the rhodanine ring group of which is considered to be an electron acceptor and the quinoline group part is an electron donor, forms a color by forming an intra-molecular charge transfer type complex. The uniform thin film which generates the carriers with the visible light, dissolves in a solvent and is subjected to molecular dispersion by mere coating is thereby obtd. |
