Abstract

1,254,196. Photoconductive composition. EASTMAN KODAK CO. 3 April, 1969 [8 April, 1968], No. 17499/69. Heading H1K. An organic photoconductor is sensitized by a cyanine dye comprising first and second nitrogen-containing-hetarocyclic nuclei having 5 or 6 carbon atoms in the heterocyclic ring, joined by a dimethine-linkage wherein the first nucleus is a carbazole nucleus joined at the 3-carbon atom thereof to the dimethine linkage and the second nucleus is joined by a carbon atom to the linkage. In the specific embodiment an electrophotographic plate is made by coating a mixture of a polyester, 4,4<SP>1</SP>-bis-(diethylamino) - 2,2<SP>1</SP> - dimethylphenylmethane and 1,3 - diethyl - 2 - # - (9 - methyl - 3 - carbazolyl vinylimidazo - [4,5 - b]- quinoxalinium iodide on an aluminium surface. Other suitable sensitizing dyes and organic photoconductors are specified.
