Abstract: Amphipathic copolymers are provided comprising one or more S portions and one or more D portions. The copolymers have a chromophore covalently bonded thereto via a urethane, urea or amide linkage. These copolymers provide exceptionally useful components in toner compositions, because they provide easily prepared color-imparting particles that provide excellent color rendition.

Abstract: Liquid electrographic toner compositions are provided comprising a liquid carrier having a Kauri-Butanol number less than about 30 mL and a plurality of toner particles dispersed in the liquid carrier. The toner particles comprise polymeric binder and a pigment comprising a first ionic dye component ionically complexed with a second ionic dye component in a predetermined ratio to form an ionically complexed colorant compound exhibiting a predetermined color. The colorant compound has a molecular weight of less than about 5000 Daltons and is substantially free of metals that are not covalently bonded to the colorant compound. Toners comprising pigments comprising a ionic dye component and a second ionic dye component complexed to form ionically complexed compounds that together in a colorant composition exhibit a predetermined color are also provided. Methods of making and using these toners are disclosed.

Abstract: This invention related to an intermediate transfer member for electrophotography that includes a substrate; and a polymeric layer on said substrate wherein the polymeric layer comprises an organic titanate and a polymer selected from the group consisting of fluorosilicone, silicone, and a combination thereof.

Abstract: Release compositions include (a) from zero to about 30 parts by weight of a polymer selected from the group consisting of wherein R1, R2, R3, R6, R7, R10, R11, and R12 are each independently selected from an alkyl group, an alkenyl group, an aryl group, and an aralkyl group, such that at least one of R6 and R7 is an alkenyl group, l, m, and n are each independently an integer so long as the polymer contains greater than 3 mol % vinyl-containing siloxane groups; a (vinyl siloxy)(siloxy)-modified silica having a vinyl content of at least about 0.

Abstract: A no-process printing plate forming photosensitive article having a protective top coat layer is described. The top coat layer may be a water soluble or dispersible polymer, sol, salt, or mixture thereof. The protective top coat layer may provide the no-process printing plate with protection from contamination during handling, improved suppression of odors during imaging, and improved roll-up performance on press. The hydrophilic protective top coat is removed on press by action of the fountain solution and/or ink.

Abstract: Acid-sensitive polymers and imageable articles employing them are disclosed. In particular, photosensitive compositions are disclosed comprising: (a) a photoinitiator which generates an acid upon exposure to radiation; and (b) a polymer having acid labile groups pendant from the polymer backbone, said acid labile pendant groups comprising at least one each of A and B wherein A has the formula --T-(C.dbd.O)OCR.sup.1 R.sup.2 OR.sup.3, and B has the formula --T-(C.dbd.O)OR.sup.4 Si(R.sup.5).sub.3, wherein R.sup.1 and R.sup.2 each represent H or an alkyl group with the proviso that at least one of R.sup.1 and R.sup.2 must be hydrogen; R.sup.3 represents an alkyl group; or any two of R.sup.1, R.sup.2, and R.sup.3 may together form a ring group having from 3 to 36 carbon atoms; R.sup.5 represents an alkyl group, aryl group, an alkoxy group, an aryloxy group, an acyloxy group, or a trialkylsiloxy group; and R.sup.4 and T represents a divalent linking group wherein T is bonded to the polymer backbone and R.sup.
