Anthony C. Giudice 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).

  • Lithographic plate with disperse particulate rubber additive
    Patent number: 5853958
    Abstract: The present invention discloses the use of rubber and surfactant to enhance the durability and resolution of on-press developable lithographic printing plates. The rubber is preferably incorporated into a photoresist as discrete particulate rubber. To ensure a uniform and stable dispersion, the rubber is suspended in the photoresist by means of a surfactant having an HLB approximately between 7.0 and 18.0.
    Type: Grant
    Filed: October 17, 1996
    Date of Patent: December 29, 1998
    Assignee: Polaroid Corporation
    Inventors: Chieh-Min Cheng, Anthony C. Giudice, Rong-Chang Liang, William C. Schwarzel, Leonard C. Wan
  • On-press developable lithographic printing plate precursor
    Patent number: 5620827
    Abstract: A lithographic printing plate precursor for use on a printing press, with minimal or no additional processing after exposure to actinic radiation, comprises a printing plate substrate, a polymeric resist layer capable of imagewise photodegradation or photohardening, and a plurality of microencapsulated developers capable of blanket-wise promoting the washing out of either exposed or unexposed areas of the polymeric resist. The microencapsulated developers may be integrated into the polymeric resist layer, or may form a separate layer deposited atop the polymeric resist layer, or may be coated onto a separate sheet support capable of being brought into face-to-face contact with conventional printing plates.
    Type: Grant

  • Printing plate and methods of making and using same
    Patent number: 5407764
    Abstract: A lithographic printing plate for use on a printing press, with minimal or no additional processing after photoexposure, comprises a printing plate substrate; a photosensitive hydrophilic layer having a polymeric hydrophilic binder and a photopolymerizable, photocrosslinkable or photorearrangeable compound capable of promoting insolubilization or hardening in areas of photoexposure; and a photosensitive hydrophobic layer having a polymeric hydrophobic binder and a photopolymerizable, photocrosslinkable or photorearrangeable compound capable of promoting insolubilization or hardening in areas of photoexposure.
