N,N′-二(芳磺酰)亚磺酰胺-S-(2-苯并咪唑)钠作为稳定剂的研究

STUDY OF SODIUM S (2 BENZIMIDAZOLYL) N,N′ DI (ARYL SULFONYL)SULFENAMIDE AS STABILIZER

研究了新型感光稳定剂Ｎ，Ｎ′－二（芳磺酰）亚磺酰胺－Ｓ－（２－苯并咪唑）钠（芳磺酰基为苯磺酰，对甲苯磺酰，对氯苯磺酰）与增感染料在实用照相乳剂中的超增感与防灰雾作用。实验结果表明，在多种不同组分的卤化银乳剂中，可提高感光度，抑制灰雾或对感光度和灰雾具有一致的理想效果。

The supersensitive combination of new photographic stabilizer sodium s (2 benzimidazolyl) N,N′ di(benzoylsulfonyl) sulfenamide,sodium s (2 benzimidazolyl) N,N′ di(p toluylsulfonyl) sulfenamide and sodium s (2 benzimidazolyl) N,N′ di(p chlorobenzolsulfonyl) sulfenamide with sensitive dye and as antifoggant in practical emulsions were studied.The experimental result shows that the sensitivity was increased and fog was suppressed,even exhibits consistent superior perfomances in sensitivity and in fog,when used in the silver halides photogrephic emulsions of different halides.
