Definitions

  • each R can be hydroxy, alkoxy or halogen and each R can be hydrogen, alkyl, aryl, hydroxy, alkoxy or halogen.
  • a useful range for the concentration of the stabilizer is from about 0.5 gram to about 20 grams per mole of silver halide.
  • suitable compounds include 3,4 dihydroxy 3 cyclobutene 1,2 dione, 3 methoxy- 4 phenyl 3 cyclobutene 1,2 dione, 3 hydroxy 4- phenyl 3 cyclobutene 1,2 dione, 3,4 diethoxy 3- cyclobutene 1,2 dione, 3,4 diethoxy cyclobutane 1,2/- dione, 3 bromo 4 phenyl 3 cyclobutene 1,2 dione, and 3,4-dihydroxycyclobutane-1,2-dione.
  • Photographic silver halide emulsions and elements stabilized as described can be chemically sensitized, e.g., with noble metal sensitizers alone or in combination with sulfur or selenium sensitizers. They can contain spectral sensitizers, incorporated color forming couplers, incorporated developing agents, other antifoggants, hardeners, plasticizers, coating aids, and other suitable photographic addenda, such as described in US.
