摘要： PURPOSE:To obtain the subject composition capable of outputting input light in the form of digital signal and, accordingly, useful as a sensitive material for digital recording electrophotography by mixing three specific kinds of phthalocyanine derivatives at specific ratios and heating the mixture in a specific solvent. CONSTITUTION:The objective composition is produced by mixing (A) 100 pts.wt. of a compound of formula I (M is H, atom or compound capable of forming covalent bond or coordinate bond with phthalocyanine) with (B) 0.001-5 pts.wt. of a compound of formula II (R to R are H, halogen or nitro and at least one of R to R is not H) and (C) 0.01-10 pts.wt. of a compound of formula III (R to R are H, halogen or electron-attracting group and at least four of R to R are not H) and heating the obtained mixture in an organic solvent excluding aromatic organic solvent. This composition is produced generally by producing phthalocyanines using a phthalocyanine ring-forming compound and the above raw material compound substituted with halogen or nitro and heating the obtained mixture of the components A and B together with the component C in the above organic solvent.

摘要： PURPOSE:To obtain an anisotropic photoconductive thin film element having excellent photoconductive anisotropic and a large area by forming a specific high crystal polydiacetylene thin film on a board. CONSTITUTION:Diacetylene monomer represented by a formula [R and R are -(CH2)4OCONH-CnH2n+1, (n) is integer number of 1-20] is deposited, and a monomer thin film is formed on its board. Then, the film is irradiated with ultraviolet rays by using an ultrahigh pressure mercury lamp, and solid polymerized to obtain a diacetylene polymer thin film. The surface is rubbed only in one direction parallel to a voltage applying direction by using a silicon cloth. Then, diacetylene monomer is further deposited on the rubber film, similarly irradiated with ultraviolet rays, solid polymerized to obtain a photoconductive thin film element made of the film. Dichroic constant is molecular-oriented to three or more, and photoconductive anisotropy is oriented to two or more.
