ABSTRACT:
An imaging sheet useful in forming images on plain paper, said sheet comprising a support having a plurality of photosensitive microcapsules and a developer-containing resin on the surface thereof, said microcapsules and said developer-containing resin being present in the same layer or in contiguous layers on the surface of said support, said microcapsules containing an internal phase which includes a photosensitive composition which changes in viscosity in response to exposure to actinic radiation and a color former which is capable of reacting with said developer and forming a visible dye image, said imaging sheet being useful in forming images by a process which comprises image-wise exposing said imaging sheet to actinic radiation, assembling said imaging sheet with a sheet of plain paper, heating said assembly, subjecting the assembly to a uniform rupture and transfer force, and separating said imaging sheet from said paper such that said image areas are area-wise transferred to said plain paper.
