The presensitized lithographic printing plate comprises a hydrophilic support and the image-forming layer. The image-forming layer contains a compound or a polymer having o-quinodimethane structures or precursor structures thereof. The lithographic printing plate is prepared by a reaction of the o-quinodimethane structures.Field of SearchLithographic plate making, and processes of making or using copy elements, and elements per seMaking plate surface portions ink repellent or ink receptive By use of radiant energy or heat MICROCAPSULE, PROCESS, COMPOSITION, OR PRODUCT Radiation sensitive composition or product or process of making Radiation sensitive composition comprising ethylenically unsaturated compound Resin or prepolymer containing ethylenical unsaturation Lithographic Relief Post imaging process THERMOGRAPHIC PROCESS POST IMAGING PROCESSING Developing INCLUDING EXPOSURE STEP OR SPECIFIED PRE-EXPOSURE STEP PERFECTING EXPOSURE INFRARED LASER BEAM |
