  • Patent number: 6497961
    Abstract: A ceramer composition is provided that comprises a plurality of colloidal inorganic oxide particles and a free-radically curable binder precursor. The free-radically curable binder precursor comprises a fluorochemical component that further comprises at least two free-radically curable moieties and at least one fluorinated moiety. By virtue of the inclusion of the fluorochemical component, the ceramer compositions of the present invention can be used to provide ceramer composites and ceramer composite structures with excellent stain, oil and/or water repellency characteristics as well as a high level of abrasion resistance and hardness.

  • Patent number: 6458462
    Abstract: A sporting goods article with a coating on a surface of the article for abrasion resistance and/or a high gloss appearance. The outer layer of the surface is a polymer, wood, metal, non-polymeric ink, non-polymeric colorant, non-polymeric dye, or a combination thereof The coating is a cured ceramer composition. The cured ceramer composition, in its simplest embodiment, is derived from a composition including inorganic oxide particles and a curable organic matrix, with the curable organic matrix including at least one ethylenically unsaturated monomer and at least one organofunctional silane monomer coupling agent.

  • Patent number: 6132861
    Abstract: A retroreflective article comprising a substrate and a cured ceramer coating provided on at least a portion of a surface of the substrate. The coated portion of the surface is retroreflective. The coating comprises a cured ceramer composite derived from ingredients comprising a free radically curable binder precursor and a plurality of surface treated, colloidal inorganic oxide components. The colloidal inorganic oxide components are surface treated with a surface treatment agent comprising a fluoro/silane component comprising a hydrolyzable silane moiety and a fluorinated moiety, and a crosslinkable silane component comprising a hydrolyzable silane moiety and a free radically crosslinkable moiety. The weight ratio of the crosslinkable silane component to the fluoro/silane component is from about 4:1 to 20:1, and the weight ratio of the free radically curable binder precursor to the colloidal inorganic oxide components is from about 1:10 to 8:10.

  • Patent number: 5604083
    Abstract: The invention is directed to an antistatic polymeric film base comprising a polymeric film having coated on at least one side thereof an antistatic layer comprising the reaction product of (1) a water-soluble, electrically conductive polymer containing carboxylic groups and (2) a water-soluble polymer containing oxazoline groups, and to a photographic element comprising at least one silver halide emulsion layer on said antistatic polymeric film base. This antistatic layer may be present as a backing layer on the side of the film base opposite the silver halide emulsion layer, as a subbing layer between the film base and the emulsion layer in a single or double side coated photographic element, and/or as a subbing layer between the film base and a different backing layer.
