    Abstract: A planographic printing plate formed of a support having sequentially disposed thereon a first layer, that is structured by a heat-insulating material having a low thermal conductivity, and that is made hydrophilic by being processed with one of an alkali and a silicate in an alkali developing solution after exposure; and a second layer whose alkali developability is changed, without ablation, by being irradiated with an infrared ray. Alternatively, a support that is structured by a heat-insulating material whose thermal conductivity is low, and in which a surface thereof is made hydrophilic by being processed with one of an alkali and a silicate in an alkali developing solution after exposure, may also be used as the support.

    Abstract: Provided is a positive working, wet lithographic printing member comprising a hydrophilic metal substrate having disposed thereon 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.

    Abstract: Presensitized lithographic plates are prepared which permit direct formation of printable images on plates by digital computerization without the intervening formation of a photographic image with a quality that allows the plates to be used for high volume printing applications. The lithographic printing plate has a structure which contains a substrate; a positive or negative working photosensitive layer; and a thermally sensitive masking layer which is opaque to the actinic radiation but which is soluble in an aqueous medium. The masking layer contains a heat softenable disperse phase which is insoluble in the aqueous medium; a polymeric continuous phase which is soluble or swellable in the aqueous medium; and a colorant which strongly absorbs radiant energy and converts the radiant energy to heat. In use the masking layer is digitally exposed to a computer controlled laser image so that exposed image areas of the masking are insolublized in the aqueous medium; soluble areas of the mask layer are then removed to form an opaque image mask on the photosensitive layer which is then exposed to actinic radiation passing through the mask to solubilize or insolubilize exposed areas of the photosensitive layer; the photosensitive layer is then developed with the developer liquid to remove the soluble areas and any overlying mask areas to form the lithographic printing plate. Both wet and waterless lithographic printing plates may be digitally prepared in this manner.
