Abstract

1316337 Photoconductive compositions KODAK Ltd 22 Oct 1970 [22 Oct 1969] 50276/70 Heading H1K [Also in Division C4] A photoconductive composition for use in electro-photographic materials comprises organic or inorganic photoconductor sensitized with a tris(carbazol-3-yl)methane dye in which the carbazolyl group has an organic substituent in the 9-position. Lists are given of photoconductors, binders, and backings, and of solvents for use in manufacture of the electrophotographic materials.
