  • Patent number: 7955470
    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.
    Type: Grant
    Filed: September 28, 2009
    Date of Patent: June 7, 2011
    Assignee: Ferro Corporation

  • Patent number: 7014701
    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.
