Abstract
A self-contained photohardenable imaging assembly comprising in order: a first transparent support; an imaging layer comprising a developer material and a plurality of photohardenable microcapsules encapsulating a color precursor, and a second support, wherein at least one support comprises a barrier layer that exhibits a low water vapor transmission rate. The imaging assembly has been found to provide better image quality and more consistence sensitometric response to pressure development.
