| 摘 要： | 热敏CTP版材的热敏涂层主要包括成膜树脂、阻溶/促溶剂、红外染料、热生酸剂和背景染料等,选用的间酚和混酚两种成膜树脂需要具有一定程度的抗碱性能,才能满足版材显影的需求。采用紫外分光光度法,并选择结晶紫作为示踪染料,考察成膜树脂的碱溶性规律,并逐步考察阻溶/促溶剂、红外染料以及两者共同作用对成膜树脂碱溶性的影响。结果表明,混酚树脂的抗碱性大于间酚树脂;通过添加各种组分,发现各组分对混酚树脂抗碱性的影响大于间酚树脂。混酚树脂可以满足版材对成膜树脂抗碱性的要求。

| Abstract: | The thermal sensitive coatings of the CTP plate included film-forming resin,inhibitational/accelerational resin,infrared dyes,thermal acid generator and background dye and so on,besides both m-cresol resin and mixed cresol resin must have certain anti-alkaline to ensure the development latitude of plate.This study chose crystal violet as indicator and adopted ultraviolet spectrophotometry method to investigate alkaline solubility of the film-forming resin,and then gradually studied inhibitational/accelerati... |
