Abstract
A thermally imagable element suitable for use as a lithographic printing plate is disclosed. Imagable element contains an ink repellent, thermally sensitive surface layer on a substrate. The surface layer contains an ink repellent, thermally sensitive co-polymer which is both thermally sensitive and has the physical properties needed for handling and printing. The thermally sensitive co-polymer contains two types of segments: (a) soft silicone segments, which repel ink, and (b) hard segments, which provide physical integrity and impart thermal sensitivity to the co-polymer. The element can be imaged by imagewise expose either by infrared radiation or by heat. The process requires no wet development step and no wiping. Thermally labile crosslinked polymers are also disclosed.
