  • Patent number: 8354213
    Abstract: The present disclosure provides processes for producing images of excellent color fidelity when incorporating a cyan toner with a lower colorant loading in addition to a first cyan toner. In embodiments, the cyan pigmented particles may be cyan emulsion aggregation toners. In accordance with the present disclosure, a pair of cyan toners are matched in color, wherein the color of a first cyan toner printed at a predetermined halftone area coverage on a substrate substantially matches the color of the solid (100%) printed patch of the second cyan toner, which is lighter than the first cyan toner, thus avoiding a visible hue shift on the print that would otherwise be objectionable. In embodiments, the light cyan toner is color matched by adding a hue-adjusting colorant or combination of colorants which absorb wavelengths of light between 500 and 600 nanometers, and optionally adding a shade-adjusting colorant or combination of colorants which absorb wavelengths of light between 400 and 500 nanometers.

  • Publication number: 20040121255
    Abstract: A fusing-station member, which member can be a compliant fuser roller or a compliant pressure roller, for use in a fusing station of an electrostatographic machine, and which member includes a base cushion layer formed on a core member, with the base cushion layer coated by a thin protective gloss control layer. In certain preferred embodiments, the base cushion layer is a highly cross-linked condensation-polymerized polyorganosiloxane material made by thermal curing of a formulation which includes three types of filler particles, namely hollow flexible microballoon particles, strength-enhancing solid particles, and thermal-conductivity-enhancing solid particles. In other preferred embodiments, expandable microspheres are included in lieu of the hollow flexible microballoon particles in an otherwise similar uncured formulation, which expandable microspheres are transformed into expanded hollow microballoon particles during the thermal curing.

  • Patent number: 6479203
    Abstract: A direct drawing type lithographic printing plate precursor comprising a water-resistant support having provided thereon an image receiving layer, wherein the image receiving layer comprises particles having rough surface composed of core particles having on the surfaces thereof fine particles adhered, and a binder resin comprising a complex composed of a resin containing a siloxane bond in which a silicon atom is connected with an oxygen atom and an organic polymer containing a group capable of forming a hydrogen bond with the resin containing a siloxane bond. According to the use of the direct drawing type lithographic printing plate precursor of the present invention, images free from not only background stain over an entire surface but also dot-like stain can be formed thereon. Also, the direct drawing type lithographic printing plate precursor can prepare a lithographic printing plate providing a great number of printed matter having clear images free from disappearance or distortion of image.

  • Patent number: 6268101
    Abstract: The present invention relates to imaging elements, including photographic elements and recording media, having a protective overcoat that resists fingerprints, common stains, and spills. More particularly, the present invention provides a water permeable overcoat during image formation but that is water resistant in the final processed product. The overcoat, before formation of the image, comprises polyurethane particles in a gelatin-containing matrix. Subsequent to formation of the image, the overcoat is heat fused, resulting in the formation of a water-resistant continuous protective overcoat that provides excellent scratch and spill resistance.

  • Patent number: 5986031
    Abstract: Allylic copolymer resins and processes for making them are disclosed. The resins are made by copolymerizing an ethylenic monomer, a monofunctional allyl monomer, and a multifunctional allyl monomer under free-radical conditions. The multifunctional allyl monomer is used in an amount and manner effective to give a copolymer resin having a polydispersity (Mw/Mn) within the range of about 5 to about 30. The resins, which are easy to make with even bulk polymerization, are particularly valuable, for example, as toner resins, thermoset resins, reactive plasticizers, and rheology modifiers.

  • Patent number: 5773182
    Abstract: A light-stable colored composition which includes a colorant and a radiation transorber. The colorant, in the presence of the radiation transorber, is adapted, upon exposure of the transorber to specific, narrow bandwidth radiation, to be mutable. The radiation transorber also imparts light-stability to the colorant so that the colorant does not fade when exposed to sunlight or artificial light.
