| 摘 要： | 本文研究了由偏二氯乙烯-丙烯酸甲酯共聚合物(VdCl2-MA)和五甲氧基红指示剂组成的酸敏变色记录材料的光谱特性,测定了其光分解量子产率.通过添加光敏剂使原来只有在254nm紫外光下曝光才能发生光分解反应的酸敏变色材料在35nm紫外光下曝光也可发生光分解而变色.酸敏变色材料在254nm处紫外光曝光量子产率为0.032-0.020;在35nm处紫外光曝光量子产率为0.110-0.034.光敏剂的加入使酸敏变色材料量子产率提高了2-4倍.

| Abstract: | The spectral characteristics and photolysis quantum yields of ACRM composed of vinylidene chloride-methyl acrylate(VdCl2-MA) copolymer and pentamethoxyl red were measured.By adding photosensitizer MK,the ACRM that can not only be photolyzed by exposure at 254 nm UV light but can be photolyzed by exposure at 365 nm UV light.The quantum yields of ACRM without photosensitizer at 254 nm is 0.032-0.020,and the quantum yield of ACRM with photosensitizer at 365 nm is 0.11-0.034.The quantum yields of ACRM with photosensitizer is improved by 2-4 times. |
