  • Patent number: 11346052
    Abstract: A surface treatment composition for paper, board or other fibrous webs. The composition of the invention comprises particles which comprise an active material and a supporting material. The active material comprises a salt of a multivalent metal, such as a divalent or trivalent metal. In accordance with the invention, the supporting material is adapted to release the active material from the particles when subjected to heat and/or pressure and/or a change in pH. Consequently, the active material's adverse effects on the rheology of the composition are avoided while its desired effects on the surface characteristics are retained or enhanced.

  • 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.

  • Patent number: 7008740
    Abstract: The present invention provides a transfer member containing a polyimide resin and carbon black. The carbon black has a pH value of no more than 5 and a volatile component of at least 3.5%, and the content of carbon black is 22 to 30 parts by weight relative to 100 parts by weight of the polyimide resin. The invention also provides a method for manufacturing a transfer member comprising the steps of: dividing a poly(amic acid) resin solution containing carbon black into plural portions, and mixing the divided solutions by allowed the solutions to collide with each other at a pressure of at least 150 MPa; and forming a transfer member containing the polyimide resin using the poly(amic acid) resin solution, which has the carbon black mixed therein. The invention further provides an image forming apparatus using the transfer member above.

    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.

    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.
