PURPOSE:To improve the storage stability of the dispersion coating liquid and to improve the various characteristics, such as high sensitivity and high durability, of the above device by incorporating a specific phthalocyanine deriv. into the coating liquid. CONSTITUTION:The phthalocyanine expressed by formula I or II is incorporated into the coating liquid. In formulas I and II, Me denotes two hydrogen atoms or group I to group VIII metal atoms of periodic law table; iota denotes 0 or 1 integer; Y denotes oxygen atom or sulphur atom; m denote 0 or 1 integer; R denotes a hydrogen or substd. or unsubstd. alkyl group, aryl group or heterocyclic group; n denotes 0 or 1 integer; a denotes 0 to 16 integer' X denotes a halogen atom, such as chlorine atom or bromine atom; b denotes 0 to 4 integer; PC denotes a phthalocyanine group. The storage stability of the dispersion coating liquid is improved in this way and in addition, the various performances of the photoelectric device are correspondingly improved. |
