ABSTRACT:
An imaging sheet comprising a substrate having an open porous matrix and a photohardenable composition contained within said porous matrix; said imaging sheet being useful in a process wherein said sheet is image-wise exposed to actinic radiation and is subjected to pressure to cause said photohardenable composition to image-wise exude from said porous matrix to a receiver sheet is disclosed. Also disclosed is a process for forming an image by using the inventive imaging sheet, an imaging system including the inventive imaging sheet, and a process for forming a lithographic printing plate by using the inventive imaging sheet.
