Abstract

1296862 Photoconductive element INTERNATIONAL BUSINESS MACHINES CORP 8 Dec 1969 [23 Dec 1968] 59767/69 Heading H1K [Also in Division C2] A photoconductive element comprises a photoconductive compound of formula wherein A is X is CH = N, N = CH N = N, CH = CH-CH = N or N = CH-CH = CH, R is hydrogen, nitro, dialkyl amino or dialkyl aminophenylazo and alkyl is methyl or ethyl. The compound is preferably dichroic and may be used in a contact reflex reproduction process as described in Specification 1,244,765. The compound may be applied as an organic solvent solution to a substrate of glass, paper, plastic, aluminium or cellulose acetate coated with aluminium. A resin binder may be used if desired and a coating of polyvinyl carbazole, 1,3-dinitronaphthalene and polymers of esters of acrylic and methacrylic acids applied to the photoconductive coating. In the specific embodiments R is H, NO 2 , dimethylamino, julolidinidene and dimethylaminophenylazo.
