Abstract: A thermally sensitive imaging member can be imaged using thermal energy such as from an IR-emitting laser and then used for lithographic printing. The imaging member includes a support having an ink-repellant subbing layer and a thermally sensitive, ink-repellant surface imaging layer. Imaging causes a “switching” in the exposed surface regions to a more oleophilic or ink-accepting nature. Post-imaging processing is unnecessary in this imaging system. The surface imaging layer includes a thermally sensitive copolymer of silicone “soft” segments and thermally sensitive “hard” segments as well as a photothermal conversion material that is IR radiation sensitive.

Abstract: A thermal imaging member can be imaged using infrared radiation such as from an IR-emitting laser and used for lithographic printing. The imaging member includes a support having an ink-repellant thermally sensitive imaging layer and an ink-repellant surface layer that is swellable in waterless ink solvents. Imaging ablates the imaging and surface layers, but minimal debris is generated so wiping or washing is not required. The imaging layer including a thermally sensitive copolymer of silicone “soft” segments and thermally sensitive “hard” segments, as well as a photothermal conversion material that is IR radiation sensitive.

Abstract: A lithographic imaging member, such as a printing plate, has a support having thereon an ink-accepting melanophilic layer and an ink-rejecting siloxane surface melanophobic layer. Within the printing plate is a photothermal conversion material capable of converting irradiation, such as IR radiation, to heat in exposed regions. Also within one of the layers is a compound that upon imaging releases a moiety that facilitates degradation of the surface melanophobic layer. The released moiety can be fluoride ion or a fluoride ion-containing compound. In some imaging members, a barrier layer may be interposed between the two other layers. Such imaging members can be digitally imaged and used for printing without post-imaging processing.

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.

Abstract: A lithographic imaging member has a support having thereon a melanophobic silicone copolymer layer and a contiguous surface melanophilic layer composed of an inorganic or organic polymeric matrix. Either or both layers includes a photothermal conversion material capable of converting irradiation, such as IR radiation, to heat in exposed regions. The imaging member can include in one or more layers a material capable of promoting adhesion across the interface of the contiguous layers. This imaging member can be digitally imaged, for example using a laser, and used for printing without wet processing.
