ABSTRACT:
A photosensitive transfer imaging system comprising an imaging sheet and a developer sheet; the imaging sheet incudes a photographic support, a layer of photosensitive microcapsules on one surface of the support wherein the microcapsules have a discrete capsule wall and contain a chromogenic material and a photosensitive composition such as a polyethylenically unsaturated compound and a photoinitiator; the developer sheet includes a support member and a layer of a developer composition such as a salicylic acid salt; the imaging sheet and/or the developer sheet additionally includes a plurality of microcapsules which contain an oil in which the chromogenic material is soluble; images are formed by image-wise exposing the imaging sheet to actinic radiation and rupturing the microcapsules in contact with the developer sheet whereupon the chromogenic material is image-wise transferred to the developer sheet.
