Abstract

1,166,451. Photoconductive element. KODAK Ltd. 15 Sept., 1966 [16 June, 1965], No. 25496/65. Heading H1K. [Also in Division G2] A layer having a differential conductivity pattern is made by image-wise exposure of a layer containing a photoconductor and a photolysable compound which modifies the sensitivity of the photoconductor to a greater or lesser amount than its photolytic products, thereby decomposing the photolytic compound in an imagewise pattern. The photolysable compound may modify either the intrinsic or spectral sensitivity of the photoconductor. The photoconductor may be ZnO, polyvinylcarbazole or a polyester. The photolysable compound may he a pyrilium or thiapyrilium compound, CBr 4 , CHI 3 or C 2 HBr 5 whose photolytic products combine with diphenylamine, triphenylamine or a benzothiazole to give a sensitizer. Trimethylchlorosilane, alkyl thiourea, leuco Crystal Violet or a benzopyran may be used as additives. A1 or Al-coated paper may be used as a substrate. After forming the differential conductivity pattern, the remaining photolysable compound must be reduced or heated to render it insensitive to further photolysis, alternatively the light source used to produce the charge-pattern image must not induce photolysis, e.g. a medium or low intensity tungsten lamp may be used. After image-wise exposure of the initial layer a second overall exposure is given after electrostatic charging, thus giving a charge-pattern image which is developed by particle deposition. Alternatively the initially exposed layer may be uniformly exposed on one side and electrolytically developed on the other.
