Abstract
Vesicular images are formed by thermal imaging of imageable layers containing thermally imageable vesicular imaging compositions. The vesicular images can be used as masks for imaging printing plate precursors. In one aspect, a printing plate precursor made up of a flexible substrate; a photosensitive layer that contains a negative working photosensitive composition; an optional barrier layer; and the imageable layer is thermally imaged to produce an integral mask. Blanket exposure through the mask with ultraviolet and/or visible radiation followed by development produces a printing plate. The method is especially suited for the production of flexographic printing plates.
