Abstract

Photoconductive resinous compositions contain zinc oxide, a synthetic resinous insulating binder therefor and, as sensitiser, a methine or polymethine dyestuff containing a mercapto group (or enolizable equivalent thereof such as -CS-NH-) in a heterocyclic ring. Many suitable dyestuffs are mentioned, these being merocyanines or homopolar trinuclear carbocyanines. Specified resins are silicones, siliconealkyds, styrene-butadiene copolymers, styrenealkyds, soya-alkyds, polyvinyl chloride and polyvinyl acetate. The compositions are made as in Specification 885,716. Specifications 188,030, 450,958, 466,097, 489,335, 528,803, 740,770, 751,318, 885,717 and 954,018 also are referred to.
