Definitions

  • the internally doped high chloride silver halide grains are surface chemically sensitized with gold sensitizers employed alone or in combination with other conventional chemical sensitizers.
  • the internally doped high chloride silver halide grains can be surface gold sensitized with one or a combination of conventional gold sensitzers.
  • Illustrative gold sensitizers include gold hydroxide, gold chloride, potassium aurate, potassium auriaurite, potassium auricyanide, potassium aurithiocyanate, gold sulfide, gold selenide, gold silver sulfide, gold iodide, potassium chloroaurate, ethylenediamine-bis-gold chloride and various organic gold sensitizers, as more fully described by U.S. Patents 2,642,361 and 3,297,447.
