一种高分辨力高感光度的阳图平印版感光组合物
摘要：
一种高分辨力高感光度的阳图平印版感光组合物。该本发明提供感光组成物以至少含有如下三种结构的内防光晕化合物中的一种为特征，组合应用215重氮萘醌磺酸酯和214重氮萘醌磺酸酯，同时含有一种或多种线型酚醛树脂，一种光产酸源，一种或多种显影促进剂，一种背景染料等。使用该感光组合物制备的感光平印版，具有感光速度快，分辨率高，曝光宽容度大，弱碱显影性能好，耐印力较高等特点，版材适于UV-CTP制版。结构I 结构II 结构III
摘要（英）：

The invention relates to a positive lithograph plate photosensitive composition with high resolution and high sensitivity. The photosensitive composition provided by the invention is characterized by comprising at least one of three-structure antihalation compounds, uses 215 diazonaphthoquinone sulphonate and 214 diazonaphthoquinone sulphonate jointly, and has one or more of linear phenolicresin,one photoacid generator, one or more of development accelerator, one background dye and the like. The photosensitive lithograph plate manufactured by the photosensitive composition has the characteristics of rapid photosensitive speed, high resolution, large exposure latitude, good weak base development performance, higher pressrun and the like, and the plate is suitable for UV-CTP platemaking.
