Abstract: A self-contained imaging sheet comprising in order:(a) a support;(b) a first layer comprising photosensitive microcapsules having an internal phase, said internal phase comprising an image forming agent and a photosensitive composition which undergoes a physical transformation in response to exposure to actinic radiation;(c) a second layer comprising a developer material; and preferably(d) a third layer comprising an adhesive forming component, said self-contained imaging sheet being useful in forming images on plain paper by a process which comprises imagewise exposing said imaging sheet to actinic radiation, forming an image on said developer material, transferring the image bearing developer layer to said plain paper, and separating said imaging sheet from said plain paper, wherein said image bearing developer layer remains adhered to said plain paper and said microcapsule layer remains adhered to said support.
