摘　　要：研究了系列新型亚磺酰胺类化合物与增感染料在实用照相乳剂中的超增感作用。实验结果表明，照相乳剂的感光度有明显的提高，增感效果高于某些常用的超增感剂。通过ＥＳＲ信号及极谱半波电位的测试，对超增感机理进行了解释。The supersensitive combination of new sulfenamide compounds with sensitive dye in practical emulsions was studied.The experimental result shows that the sensitivity of photographic emulsion was increased appreciably.The function of supersensitization was explained by measurement of ESR signal and polargraphic half wave potential.
