Abstract

1446966 Photoconductive polymers XEROX CORP 20 Feb 1974 [20 Feb 1973] 7762/74 Heading C3R [Also in Division G2] Photoconductive material is obtained by polymerizing in situ in a host polymer a cyclic compound of formula where Ar is a polyaromatic radical derived from naphthalene, anthracene, pyrene or carbazole, X and Y are halogen atoms or nitro, amino, alkyl, phenyl, phenoxy, alkoxy, carboxy, hydroxyl or ester radicals, and m and n are 0 or integers. The cyclic compound is mixed with the host polymer and polymerized by heating at above 180‹ C. Compounds which are electron donors or acceptors may be added to the composition as sensitizers; dyestuff sensitizers also may be included. The material is coated on a conductive substrate which is electrically charged, the coated substrate is exposed to a pattern of light and shadow so that the surface charge is selectively dissipated and the latent image is developed or is transferred to another surface and then developed. In examples cyclobis - (anthracene - 9,10 - dimethylene) is polymerized by heating while mixed with polystyrene, polyethylene, polyvinylchloride, styrene / acrylate copolymer, styrene / butadiene block copolymer and poly-(1-vinylnaphthalene); the photoconductive material so-obtained is coated on aluminium plates, a positive electrical charge is applied and then the plates are exposed to light. Other cyclic compounds mentioned are cyclo - bis - (naphthalene - 1,4 - dimethylene) and cyclo - bis - (anthracene - 9,10- dimethylene) compounds substituted in the 1-position by bromine, chlorine, amino, nitro and methyl.
