Abstract
A method for forming images on a non-reactive substrate such as plain paper is disclosed, comprising the steps of: image-wise exposing an imaging sheet, said imaging sheet comprising a support having a layer of photosensitive microcapsules on the surface thereof, said microcapsules containing a photohardenable or photosoftenable composition including a photoinitiator, and a color precursor; assembling said image-wise exposed imaging sheet with a developer-donor sheet; subjecting said assembly to a uniform rupturing force to cause said photosensitive microcapsules to rupture and transfer an image-wise pattern of said color precursor to said developer-donor sheet thereby forming an image thereon; separating said imaging sheet from said developer-donor sheet; assembling said developer-donor sheet bearing said image with a sheet of plain paper to form a second assembly; and subjecting said second assembly to heat and a uniform force to transfer said developer to said non-reactive substrate.
