连苯三酚与二乙烯基苯缩聚树脂的活性醚化物作为阻溶剂的热敏CTP感热成像液
摘要：
本发明公开了属于光信息记录材料的应用技术领域的一种含连苯三酚与二乙烯基苯缩聚树脂的活性醚化物作为阻溶剂的热敏CTP感热成像液。该成像液包含如下组分：成膜树脂、阻溶剂、红外染料、着色背景染料、产酸剂、添加剂和溶剂。阻溶剂为连苯三酚与二乙烯基苯缩聚树脂的活性醚化物，该阻溶剂在曝光区产生的质子酸的作用下分解释放出碱溶性基团——酚羟基，使得曝光区与非曝光区的溶解差别度很大，提高了版材的显影及成像性能。该阻溶剂能够明显提高热敏CTP板材的感度、耐老化性，也能够改善热敏CTP板材的显影宽容度，提高热敏CTP版材的综合成像性能。
摘要（英）：

The invention discloses thermosensitive CTP thermal-induction imaging liquid taking an active etherate of a pyrogallol and divinylbenzene polycondensate resin as a dissolution inhibitor, belonging to the applied technology field of an optical information recording material. The imaging liquid comprises the following components: film-forming resin, dissolution inhibitor, infrared dye, coloring background dye, photoacid generator, an additive and solvent. The dissolution inhibitor is the active etherate of the pyrogallol and divinylbenzene polycondensate resin, and the dissolution inhibitor candecompose and release an alkali soluble group, namely phenolic hydroxyl under action of protonic acid generated in an exposed area so as to form great dissolution difference between the exposed area and a non-exposed area, thus enhancing developing and imaging performances of a plate. The dissolution inhibitor can obviously enhance sensitivity and ageing resistance of the thermosensitive CTP plate, improve development latitude of the thermosensitive CTP plate, and strengthen comprehensive imaging performance of the thermosensitive CTP plate.
