ABSTRACT:
Imaging systems employing photosensitive microcapsules having improved film speed are disclosed wherein the microcapsules contain a photosensitive composition in which the photoinitiator system includes a photobleachable sensitizer such as a 3-substituted coumarin compound; the invention is particularly useful in providing self-contained imaging systems which are sensitive at 390-500 nm but which can be photobleached to reduce background yellow; an imaging process including a photobleaching step following exposure and development is also disclosed.
