A system and method for producing photographic-like output. In the method, an image is formed from image forming agent(s) on a specially coated substrate, after which the combination is fused to preferably form a uniform glossy finish on the substrate. A preferred application is in an electrostatographic process, comprising a system comprising (a) toner comprising a resin component having a glass transition temperature T.sub.gT ; and (b) a coated substrate comprising a coating having a glass transition temperature T.sub.gC, where the resin component has a characteristic chemical compatibility with the coating.

High gloss electrostatographic substrates

The invention relates to a process for producing multi-layered carbonless sheets on which indicia can be xerographically produced with little or no non-specific development. The process involves coating a sheet with a CB composition containing a carboxymethyl cellulose polymer, a crosslinker, a salt of a polyvalent metal ion and a small amount of a wall forming acrylic resin. The CB coating formed resists breakage and release of dye when non-specific pressure is applied to the sheet thereby resulting in CF copies having improved brightness and reduced non-specific development.

Xerographable carbonless forms

Disclosed is a coating composition for producing a high solids content carboxymethylcellulose based 'CB' coating for use in pressure sensitive carbonless copy systems. The formulation comprises carboxylmethylcellulose, a wall-forming carboxylated acrylic resin, an organic cross-linker, a polyvalent metal salt, and an oil containing color-forming dye. The composition has a solids content of at lesat 30% and a viscosity within the range of 50 to 5000 centiposes. The CB paper exhibits the ability to produce improved imaging on computer and dot matrix printers because of better release efficiency and may be manufactured using less energy.

The formulation comprises carboxylmethylcellulose, a wall-forming carboxylated acrylic resin, an organic cross-linker, a polyvalent metal salt, and an oil containing color-forming dye. The composition has a solids content of at least 30% and a viscosity within the range of 50 to 5000 centiposes. The CB paper exhibits the ability to produce improved imaging on computer and dot matrix printers because of better release efficiency and may be manufactured using less energy.
