Abstract
Methods for forming relief images are disclosed employing photosensitive microcapsules; typically, the internal phase of the microcapsules includes a photohardenable composition such as an ethylenically unsaturated compound and a photoinitiator; release of the composition is controlled by exposure and the application of a uniform rupturing force such as pressure; in one embodiment, the released composition functions as a resist image for subsequent processing with an etching agent such as an acid.
