【摘要】 用光敏剂４，４′二（Ｎ，Ｎ′二甲基氨基）苯甲酮（简称米氏酮，ＭＫ）、引发剂邻氯代六芳基双咪唑（ｏＣｌＨＡＢＩ）和氢给体助引发剂十二烷基硫醇（ＳＨ）组成光敏引发体系．研究了在高压汞灯照射下，甲基丙烯酸甲酯（ＭＭＡ）光聚合速率和该敏化体系每一个组分，包括ＭＫ、ｏＣｌＨＡＢＩ、ＳＨ和ＭＭＡ的关系，还研究了该体系在ＰＳ版材上的应用，并获得了很好的效果更多还原

【Abstract】 The ultraviolet photosensitive initiating system is composed of 4,4’bis(N,N’dimethylamino) benzophenone (MK), 2chlorohexaarylbiimidazole (oClHABI) and a hydrogen donor coinitiator ndodecyl mercaptan (SH). Under the irradiation by high pressure mercury lamp, the relationship between the photopolymerization rate of MMA and the concentration of each component of the system, including MK, oClHABI, SH and MMA, was studied. The excellent results have been obtained through studying the system’s application on PS printing plate.\=更多还原
