Abstract: An inorganic oxide particle having an organic coating is provided. The invention also provides a process for preparing an organic coated inorganic oxide particle comprising forming an organic coating on the inorganic oxide particle. Specifically, a process for preparing an organic coated inorganic oxide particle, comprising obtaining a mixture of at least one inorganic oxide particle and at least one coating agent in at least one solvent, agitating the mixture, and removing the solvent is provided. The invention also provides an inorganic oxide particle prepared by the claimed processes, as well as the use of the inorganic oxide particle in a composition. A composition comprising the inorganic oxide particles of the invention, such as an electroconductive composition comprising the inorganic oxide particles, conductive metallic particles, and an organic vehicle is also provided.

Abstract: An acrylate-based curable printing medium is disclosed. Acrylates, in the form of monomers, dimers, trimers and oligomers, as well as resins, form an interpenetrating polymer network by crosslinking, which is effected by heat, and optionally peroxide curing agents. Formulations can be tailored to achieve desired properties of the cured polymer including film hardness, burnout properties, and adhesion to glass. Such properties are adjusted by manipulating the relative proportions of the acrylic monomers, oligomers and resins that are used as a ceramic medium or vehicle.

Abstract: The present invention provides methods of forming and detecting non-visible marks and articles marked in accordance with the methods. In accordance with the methods of the invention, a marking material is applied to a substrate to form a mark that is contrastable from the substrate in one or more regions of the infrared portion of the electromagnetic spectrum. The mark is covered with a film, which can be a bonded coating or a non-bonded covering sheet, that comprises an amount of one or more inorganic pigments such that the film appears opaque in the visible portion of the electromagnetic spectrum but is sufficiently transmissive in one or more regions of the infrared portion of the electromagnetic spectrum to facilitate the detection of the mark covered by the film. The non-visible marks can be applied to articles such as automobile parts, aircraft parts and other articles of manufacture to deter counterfeiting.

Abstract: A method of decorating laminated glass is disclosed. A pigment package composition comprising a cross-linkable thermoset resin, a crosslinker capable of crosslinking the thermoset resin, and a pigment is applied to a glass substrate. The crosslinker and thermoset resin are cured at a relatively low temperature (ca. 400° F.). The use of an organic based pigment composition allows use of thinner glass sheets than with traditional ceramic enamel pigment compositions.

Abstract: A method of laser marking substrates such as glass, ceramic, metal and plastic is disclosed. A marking material is applied to the surface of the substrate, followed by irradiation of a portion of the marking material to form a permanent marking on the substrate. The non-irradiated portion of the marking material is then removed from the substrate. The marking material may comprise glass frit or precursors thereof, inorganic pigments or precursors thereof, silicates, metal oxides, sulfides, nitrides and carbides, organometallic materials or metal powders. The marking method is highly versatile, can be performed quickly, and produces permanent marks of high resolution and contrast without damage to the substrate.

Abstract: Overprintable thermoset decorating inks and methods of applying such inks to substrates are disclosed. The decorating inks include a reactive polymeric binder resin and a crystalline crosslinker. The reactive polymeric binder resin may comprise acrylics, epoxies, polyesters, urethanes and the like which possess high Tg values. The combination of high glass transition temperature resins and crystalline crosslinkers avoids the necessity of using diluents in the coating compositions. The coating composition is applied to a substrate by heating the composition to a first temperature below the curing temperature of the coating, applying the heated coating composition to the substrate, allowing the applied coating composition to cool sufficiently so it at least partially hardens, and heating the applied coating composition to a second temperature above the first temperature for a sufficient to cure the coating composition.

Abstract: A water reducible resin for use in a coating composition is produced by grafting in organic solvent a thermoplastic polymer onto a thermosetting polymer that has been copolymerized with acid group-containing monomers to render the resultant polymer water soluble. Thermoplastic polymer is also grafted onto a phosphatized polyepoxide for the sake of adhesion of a coating to a substrate. A film formed from a waterborne coating composition containing the grafted polymers as a binder has both the toughness properties characteristic of a thermoplastic and the flexibility properties of a thermosetting resin.

Abstract: Disclosed herein is a coating composition for coloring transparent containers such as glass bottles, the composition comprising a combination of a film-former such as an acrylic resin, a metal-free polymeric dye reactive with the resin, an adhesion promoter (and optionally an ultraviolet light absorber). Also disclosed are a method of coating containers with such a composition and the resulting product.

Abstract: Disclosed herein is a combination of a film-former, a metal-free, reactive colorant, ultraviolet light absorber and an adhesion promoter in an effective combination to substantially block transmission of light through a container in order to reduce lightstruck phenomenon.

Abstract: Disclosed herein are thermosetting coating compositions comprising high Tg acrylic polymers which are substantially free of crosslinking groups, in combination with melamine resins in small but effective amounts to produce drawable cured coatings. These coating compositions are particularly useful in can coating where stringent fabricating properties and high film integrity are conjointly required.
