摘要： A lithographic printing plate for use on a printing press, with minimal or no additional processing after photoexposure, comprises a printing plate substrate; a photosensitive hydrophilic layer having a polymeric hydrophilic binder and a photopolymerizable, photocrosslinkable or photorearrangeable compound capable of promoting insolubilization or hardening in areas of photoexposure; and a photosensitive hydrophobic layer having a polymeric hydrophobic binder and a photopolymerizable, photocrosslinkable or photorearrangeable compound capable of promoting insolubilization or hardening in areas of photoexposure.

摘要： A lithographic printing plate for use on a printing press, with minimal or no additional processing after exposure to actinic radiation, comprises a printing plate substrate, a polymeric resist layer capable of imagewise photodegradation or photohardening, and a plurality of microencapsulated developers capable of blanket-wise promoting the washing out of either exposed or unexposed areas of the polymeric resist. The microencapsulated developers may be integrated into the polymeric resist layer, or may form a separate layer deposited atop the polymeric resist layer, or may be coated onto a separate sheet support capable of being brought into face-to-face contact with conventional printing plates.
摘要翻译： 用于印刷机的平版印刷版在暴露于光化辐射之后具有最少的或没有额外的处理，包括印版基板，能够成像光降解或光硬化的聚合物抗蚀剂层，以及能够覆盖 - 明智地促进从聚合抗蚀剂的暴露或未曝光区域中的洗涤。 微囊化的显影剂可以整合到聚合物抗蚀剂层中，或者可以形成沉积在聚合物抗蚀剂层顶上的单独的层，或者可以涂覆到能够与常规印刷版面对面接触的单独的片材载体上。

摘要： The present invention discloses the use of rubber and surfactant to enhance the durability and resolution of on-press developable lithographic printing plates. The rubber is preferably incorporated into a photoresist as discrete particulate rubber. To ensure a uniform and stable dispersion, the rubber is suspended in the photoresist by means of a surfactant having an HLB approximately between 7.0 and 18.0.
摘要翻译： 本发明公开了使用橡胶和表面活性剂来提高印刷可印刷的平版印刷版的耐久性和分辨率。 橡胶优选作为离散的颗粒状橡胶掺入到光致抗蚀剂中。 为了确保均匀和稳定的分散体，橡胶通过HLB约为7.0至18.0的表面活性剂悬浮在光致抗蚀剂中。
