ABSTRACT:
A process for forming a colored image comprising, in order: (a) applying at least one aqueous permeable colorant-containing composition to a photosensitive element comprising a permanent carrier element having a carrier surface, and an unpigmented, first photosensitive layer consisting essentially of an aqueous liquid developable photosensitive composition, wherein the aqueous permeable colorant-containing composition is applied to the unpigmented, first photosensitive layer; (b) imagewise exposing to actinic radiation the photosensitive element having applied thereon the permeable colorant-containing composition to form imagewise exposed and unexposed regions in the unpigmented, first photosensitive layer and the overlying permeable colorant-containing composition; and (c) developing the exposed element by washing with an aqueous liquid, thereby removing either the imagewise exposed or imagewise unexposed regions, to produce a first colored pattern is described.
