| 摘 要： | 本文通过GC/MS谱分析研究了重氮负性胶片中醚类封闭偶合剂的解封历程。测定了二种胶片的紫外-可见吸收光谱。讨论了感光特性曲线。结果表明在重氮负片成像过程中使用封闭偶合剂MEM-α-萘醚的重氮胶片由酸催化解封主要是分子内重排。而使用叔丁基-α-萘醚的胶片由酸催化解封主要是脱除保护基的断裂产物。二种胶片相比,前者的感光度比较高,而且它的图像片中染料的吸收峰向长波移动。

| Abstract: | In this paper, two unblocking courses of the ether blocked-couplers in negative diazo type film have been studied by GC/MS analysis.UV-Vis.absorption spectra of imagingfilms have been measured and the photo-sensitive characteristic curves have been discussed.Results showed that the negative film based on the acid-induced rearrangement of blockedcoupler is more photosensitive than the film based on the acid-induced cleavage in theimaging process.The maxinum absorption peak of the former image is shifted towards longer-wavelength. |
