Abstract: A thermal lithographic printing plate, which can be imaged by thermal energy typically by imagewise exposure with an infrared emitting laser, a thermal printing head, etc., is made up of a hydrophilic substrate, and a composite layer structure composed of two layer coatings. Preferably, the first layer of the composite is composed of an aqueous developable polymer mixture containing a photothermal conversion material which is contiguous to the hydrophilic substrate. The second layer of the composite is composed of one or more non-aqueous soluble polymers which are soluble or dispersible in a solvent which does not dissolve the first layer. The plate is exposed with an infrared laser or a thermal print head, and upon aqueous development of the imaged plate, the exposed portions are removed exposing hydrophilic substrate surfaces receptive to conventional aqueous fountain solutions. The unexposed portions contain the ink-receptive image areas. Alternatively, the composite layer may be free of photothermal conversion material when thermal imaging is carried out using a thermal printing head.

Abstract: Provided is a positive working, wet lithographic printing member comprising a hydrophilic metal substrate having disposed theron a hydrophilic layer, an ablative-absorbing, ink-accepting surface layer and, optionally, an ink-accepting overcoat layer that is not ablative-absorbing. Also provided are methods of preparing such lithographic printing plates, and methods of preparing imaged lithographic printing plates from such lithographic printing plates by imagewise exposure to a laser and a subsequent cleaning step to remove residual laser-induced debris and damaged areas from the hydrophilic layer. The use of water-dispersible carbon blacks with polar groups on the surface of the carbon black and water-based polymers, such as a polyvinyl alcohol, in the ablative-absorbing layer, with the optional addition of the durable, ink-accepting overcoat layer that is not ablative absorbing, improves the ease of the cleaning step and also improves the image resolution, adhesion, and durability upon imaging and use of the printing member.
