ABSTRACT:
Heat-sensitive imaging element comprising a support carrying a binder layer, optionally an intermediate adhesive layer, and and a barrier layer that is ablatable by a laser beam or permeabilizable under the influence of a laser beam, wherein said binder layer contains at least one hydrophobizing agent capable of diffusing under the influence of heat through holes made in said barrier layer or through permeabilized parts of said barrier layer and capable of reacting with the oleophobic surface of a printing plate precursor brought in face-to-face contact with said barrier layer. The present invention also relates to a process for producing a lithographic printing plate, wherein use is made of such heat-sensitive imaging element.
