Nicolo Bellanca has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Laked high molecular weight dyes
    Patent number: 4167422
    Abstract: Organic pigment lakes are prepared by adsorption of a high molecular weight or polymeric dye onto suitable substratum or extender therefor. The properties of the resultant polymeric lakes approach those of true pigments, and said lakes exhibit maximized dye loading capacities and are exceptionally free of bleed. Thus, the applicability of lake colors is extended in the various food systems and their use is also permitted as industrial pigments.
    Type: Grant
    Filed: August 30, 1974
    Date of Patent: September 11, 1979
    Assignee: Dynapol
    Inventors: Nicolo Bellanca, Thomas E. Furia
  • Zoned coloration
    Patent number: 4113505
    Abstract: Viscoelastic materials are differently colored in zones with polymric dyes. When a polymeric dye is added to a zone of a viscoelastic material it does not migrate from the zone; thus permitting an essentially permanently multizoned colored product.
    Type: Grant
    Filed: May 23, 1977
    Date of Patent: September 12, 1978
    Assignee: Dynapol
    Inventors: Nicolo Bellanca, Thomas Edward Furia
  • Coloring process and colored articles
    Patent number: 3940503
    Abstract: Translucent substrates such as foodstuffs are colored by adding polymeric dyes. The dyes contain from 0.1 to 2.0 parts of nonchromophoric material for each part by weight of chromophore and are added in a weight amount equivalent to from 0.4 to 0.9 times the weight of monomeric chromophore required to give the equivalent visual shade.

  • Zoned coloration
    Patent number: 3937851
    Abstract: Viscoelastic materials such as gelled food products are differently colored in zones with polymeric dyes. When a polymeric dye is added to a zone of a viscoelastic material, such as a gelled food product, it does not migrate from the zone; thus permitting an essentially permanently multizoned colored product.
