  • Photographic emulisions improved by peptizer modification
    Patent number: 5733718
    Abstract: A radiation-sensitive silver halide emulsion for use in photographic is disclosed containing an oxidized cationic starch as a peptizer. The oxidized cationic starch facilitates emulsion precipitation and chemical sensitization.
    Type: Grant
    Filed: July 29, 1996
    Date of Patent: March 31, 1998
    Assignee: Eastman Kodak Company
    Inventor: Joe Edward Maskasky

    Assignee: Eastman Kodak Company
    Inventor: Joe Edward Maskasky
  • High bromide ultrathin tabular emulsions improved by peptizer modification
    Patent number: 5667955
    Abstract: An improved spectrally sensitized ultrathin tabular grain emulsion is disclosed in which tabular grains (a) having {111} major faces, (b) containing greater than 50 mole percent bromide, based on silver, (c) accounting for greater than 70 percent of total grain projected area, (d) exhibiting an average equivalent circular diameter of at least 0.7 .mu.m, and (e) exhibiting an average thickness of less than 0.07 .mu.m, show an enhanced capability for chemical sensitization by reason of employing an oxidized cationic starch as a peptizer.
