    摘要: A lithographic printing plate precursor 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: 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.
