  • Patent number: 9150750
    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.
    Type: Grant

    Date of Patent: October 6, 2015
    Assignee: Ferro Corporation

  • Publication number: 20060191625
    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.

  • Publication number: 20050049347
    Abstract: The present invention provides inorganic pigments including cobalt and aluminum having the spinel crystalline structure that exhibit improved color and/or weatherability in paint and polymer applications. Inorganic pigments according to the invention are formed by adding small quantities of a phosphate compound such as aluminum phosphate and, optionally, chromium (III) oxide, to a raw batch that includes a mixture of cobalt-containing and aluminum-containing inorganic pigment precursors, and calcining the raw batch to obtain the inorganic pigment.
