| titleOfInvention | Silver halide emulsion stabilized with isoselenoureas or ketoselenozolidines |
| abstract | AS A FREE BASE OR ITS SALTS IN WHICH THE GROUPS R, R1, R2 and R3 are each hydrogen or hydrocarbon residues. WHERE EACH OF R1, R2, R3, R4 and R5 is hydrogen or a hydrocarbon residue or an acid residue, or combined are not more than one selenourea derivative or its salts, a bisisoselenourea compound and L1, L2 and L3 can be hydrogen or hydrocarbon groups which can be linked together to form a completed heterocyclic ring and m is an integer of from about 0 to about 4 and n is an integer of from about 0 to about 4 such that their combined total is a positive integer of not more than about 8; and -Y- is a divalent group; or Photographic silver halide emulsions and elements comprising said emulsions are stabilized against fog by selenium-containing organic compounds having the formulae: |
