An organic photoreceptor (&ldquo;OPR&rdquo;) including a barrier layer formed from a barrier layer coating composition including a cellulosic resin, methylvinyl ether/maleic anhydride copolymer, a polyamide, a crosslinker, and a combination thereof, provides sufficient protection to the organic photoreceptor from damage due to corona-induced charge injection; is substantially inert with respect to the organic photoconductive layer; exhibits sufficient resiliency to withstand shear, compressional and tensional forces exerted on the belt as it passes through an electrophotographic system when the photoreceptor is used in an endless belt form; and provides sufficient protection to limit or prevent a liquid toner from contacting the organic photoconductor that may result in crazing and/or cracking of the organic photoreceptor during use.

Organic photoreceptors for liquid electrophotography

A negative-acting silver halide photographic element comprising a hydrophilic colloidal binder containing a silver halide emulsion and from 50 to 1000 milligrams of an anthraquinone per mole of silver halide.

Reduction of the sensitometric toe area of photographic films

Automatic processing equipment for photographic film, particularly radiographic black-and-white film, are required to handle different brands and constructions of film with the same processing chemistry. The Applicants have found that developer chemistry fluctuations seem to be very high when processing conventional films and newer, lower silver coating weight films. It has been found that the addition of an aqueous soluble, non-photosensitive bromide salt into radiographic film reduces the developer chemistry fluctuations.
