    • According to a method of preparing a lithographic printing plate substantially comprising a step of imagewise exposing a negative lithographic printing plate precursor having an image-recording layer containing (i) a sensitizing dye, (ii) a photopolymerization initiator, (iii) an addition polymerizable compound having an ethylenically unsaturated double bond and (iv) a binder polymer on a support and a step of processing the exposed lithographic printing plate precursor with an aqueous solution containing a carbonate ion, a hydrogen carbonate ion and a surfactant, the processing property is improved, a printing plate free from the tackiness on the surface thereof can be provided, even when the printing plate is stored after the development until printing, deterioration of the printing durability does not occur, and it becomes possible to conduct one solution development with a weak alkaline processing solution.
    • 根据制备平版印刷版的方法,其基本上包括成像曝光具有包含(i)增感染料,(ii)光聚合引发剂的图像记录层的负版印刷版原版的步骤,(iii)可加聚的 具有烯键式不饱和双键的化合物和(iv)载体上的粘合剂聚合物和用含有碳酸根离子,碳酸氢根离子和表面活性剂的水溶液处理曝光的平版印刷版原版的步骤,处理性能得到改善 即使在显影直到印刷之后将印刷版存储起来,也不会发生没有粘合性的印刷版,因此不会发生印刷耐久性的劣化,并且可以以弱的方式进行一个溶液显影 碱性处理液。
