    Abstract: PROBLEM TO BE SOLVED: To provide an image formable element in which ablation is suppressed to reduce cleaning frequency of a plate setter and to reduce its cost, noise and size. SOLUTION: The image formable element comprises a hydrophilic substrate, a lower layer, a barrier layer, and an upper layer, wherein the upper layer contains a first polymerized material, the lower layer contains a second polymerized material, the barrier layer contains a third polymerized material, the upper layer is ink-receptive and insoluble in an alkali developing solution, all of the upper layer, barrier layer and lower layer can be removed with an alkali developing solution after exposure of the element to heat, the lower layer contains a photothermal conversion material and the barrier layer and upper layer do not substantially contain a photothermal conversion material.

    Abstract: Positive-working thermally imageable elements, useful as printing plate precursors and having reduced ablation when thermally imaged, and methods for their preparation are disclosed. In one aspect, the elements contain a hydrophilic substrate, an underlayer, a barrier layer, and a top layer. The underlayer comprises a photothermal conversion material.
