    • A process for making a lithographic printing plate that includes in sequence an exposure step of imagewise exposing by means of an infrared laser a lithographic printing plate precursor that has provided above a support a positive-working recording layer including (Component A) a (meth)acrylonitrile-derived monomer unit- and styrene-derived monomer unit-containing copolymer, (Component B) a water-insoluble and alkali-soluble resin, and (Component C) an infrared absorbing agent and a development step of developing, using an aqueous alkali solution including a betaine-based surfactant or a nonionic surfactant, the aqueous alkali solution having a pH of 8.5 to 10.8, by removing an exposed area of the positive-working recording layer whose solubility in aqueous alkali solution has been increased by the exposure. There is also provided a lithographic printing plate made by the process for making a lithographic printing plate.
    • 一种制备平版印刷版的方法,其中依次包括通过红外激光成像曝光的曝光步骤,所述平版印刷版原版在支撑体上方设置有正性记录层,所述正性记录层包括(组分A)(甲基) 丙烯腈衍生的单体单元和苯乙烯衍生的含单体单元的共聚物(组分B)水不溶性和碱溶性树脂,和(组分C)红外线吸收剂和显影步骤,使用碱水溶液 通过除去其在碱性水溶液中的溶解度的曝光面积已经通过曝光而增加的pH值为8.5〜10.8的碱性水溶液,其含有甜菜碱型表面活性剂或非离子性表面活性剂。 还提供了通过制造平版印刷版的方法制成的平版印刷版。
