摘要： WHERE R1, R2, R3 and R4 individually represent hydrogen atoms or alkyl or aralkyl groups, and R1 and R3 may combine, respectively, with R2 R4 to form cycloalkyl groups. The sensitizing effect of the sensitizer compound can be improved by using the compound in combination with a compound which will liberate a thiosulfate ion, without increasing fog formation.

摘要： ANTI-FOGGING AGENTS FOR SILVER HALIDE PHOTOGRAPHIC EMULSIONS CONSISTING OF A COMBINATION OF (A) AN NITRATED BENZIMIDAZOLE, INDAZOLE OR BENZOTRIAZOLE COMPOUND REPRESENTED BY THE GENERAL FORMULA 1,2-(-X=Y-NH-),(O2N-)BENZENE WHEREIN X AND Y INDIVIDDUALLY REPRESENT N OR CR, WHEREIN R REPRESENTS A HYDROGEN ATOM OR ALKYL GROUP CONTAINING 1 TO 4 CARBON ATOMS, AND (B) AT LEAST ONE MEMBER SELECTED FROM POLYMERS CONTAINING GREATER THAN 50 MOL PERCENT OF RECURRING UNITS REPRESENTED BY THE GENERAL FORMULA -(CH2-CH(-N(-R1)-CO-R2))WHEREIN R1 AND R2 INDIVIDUALLY REPRESENT A HYDROGEN ATOM OR AN ALKYL GROUP CONTAINING 1 TO 4 CARBON ATOMS OR FORM, WHEN TAKEN TOGETHER WITH THE NITROGEN AND CARBON ATOMS TO WHICH THEY ARE ATTACHED, A 5- OR 7-MEMBERED HETEROCYCLIC RING. THE ANTI-FOGGING AGENT MAY BE INCORPORATED IN SILVER HALIDE EMULSION LAYERS OR IN ANOTHER LAYER ADJACENT TO THE EMULSION LAYER TO REDUCE FOG IN THE EMULSION LAYER WITHOUT A SACRIFICE IN THE SENSITIVITY OF THE PHOTOSENSITIVE MATERIALS.
