    摘要： An imageable element comprises: (A) a substrate; and (B) an imageable composition applied to the substrate comprising: (1) a first layer, comprising: (a) a photosensitive composition capable of absorbing actinic radiation; and (b) a photothermal converter; and (2) an ablatable second layer contiguous to the first layer, wherein the second layer is opaque to the actinic radiation. This imageable element advantageously is useful in both positive and negative working printing plate applications, increases the efficiency of use of mask-generating radiation such as IR radiation and eliminates the need for chemicals and additional time to create a mask.

    摘要： 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. The second layer may also contain a photothermal conversion material. Alternatively, the composite layer may be free of photothermal conversion material when thermal imaging is carried out using a thermal printing head.
