摘要： The problem of crystallization of organic photoconductive compounds in insulating binder-containing layers, which may impair the capability of those layers to produce high- resolution images, is overcome by using as the photoconductor a mixture comprising at least two compounds of the formula:
wherein R is an alkyl, substituted alkyl, aralkyl, aryl or substituted aryl group;
each of X, X', Y, and Y', which may be the same or different, is hydrogen, alkyl, substituted alkyl, alkoxy, substituted alkoxy, hydroxyl, nitro or halogen;
each of A and 8, which may be the same or different, is hydrogen, alkyl, substituted alkyl, alkoxy, substituted alkoxy, hydroxyl, halogen, unsubstituted or substituted aryl, cycloalkyl having four to ten carbon atoms and cycloalkenyl having four to eight carbon atoms; or
A and B taken together represent atoms which form with the carbon to which they are attached a substituted or unsubstituted carbocyclic ring having from 4 to 10 atoms, any alkyl, substituted alkyl, alkoxy or substituted alkoxy substituent having from 1 to 10 carbon atoms and any aryl or substituted aryl group being an unsubstituted or substituted phenyl, naphthyl or anthryl group, any substituent in a substituted aryl group being an amino, alkylamino, or dialkylamino group or a substituent as defined for X, X', Y and Y'.

摘要： @ An electrophotographic proofing method is described that uses a proofing element (1) comprising a photoconductive layer on an electrically conducting substrate capable of transmitting actinic radiation to which the photoconductive layer is responsive, and a dielectric support (2), releasably adhered to the rest of the element, comprising said photoconductive layer or an overcoat thereof, forming a surface of the element capable of holding an applied electrostatic charge. In the method the dielectric support surface is charged, and the photoconductive layer imagewise-exposed to actinic radiation, thereby forming a developable electrostatic image on the dielectric surface. The electrostatic image, in turn, is developed with toner to form a first color image. A composite color image is formed on the element by repeating the sequence one or more times with image-wise exposure of the photoconductive layer to actinic radiation transmitted through the transparent substrate, and developing over each preceding image with a different color toner. The composite toner image (10,13,14,15) is transferred with the dielectric support (2) to a receiving element (16) to form a color copy such as a three-color filter array or a color proof (19) closely simulating the color print expected from a full press run.

摘要： Electrophotographic color proofs (32) of halftone dot pattern images are made which closely simulate the dot gain of prints made with lithograpic plates and liquid inks. In forming the color proof (32), a thin transparent plastic sheet (21) having on one side an electrophotographic toner dot pattern image is laminated to a reflective support with the toner image side in contact with the support. A thicker transparent plastic sheet (30) is laminated to the other side of the thin sheet (21). The resulting color proof (32) comprising a toner dot pattern on a reflective support and covered by a thin transparent layer (21) and a thicker transparent layer (30) has an apparent increase in dot size which simulates that of a press print.

摘要： A heterogeneous photoconductive composition for use in electrophotographic materials comprises a plurality of aggregate photoconductive particles having a predominant particle size of less than 1 micron dispersed in an electrically insulating polymeric binder comprising a blend of from 50.0 to 99.9 weight percent of a non-aggregating polymer effective to reduce particle size and particle size distribution of the aggregate particles formed in the blend and from 0.1 to 50.0 weight percent of an aggregating polymer having repeating units according to the structure:
wherein

R and R 2 , taken separately are the same or different, and represent hydrogen or alkyl; or R, and R 2 , taken together represent the atoms necessary to form a cyclic hydrocarbon radical having up to 14 ring carbon atoms; and
R 3 and R 4 represent hydrogen or alkyl; provided that when R, and R 2 are both methyl, R 3 and R. must both be alkyl. The low aggregate particle size and size distribution provides high resolution and is achieved by combining a pyrylium dye in solution with the polymeric blend.
