Abstract
The invention is generally accomplished by a method wherein a dry photographic image is formed in an imaging-forming donor layer. The formed image is allowed to diffuse to a receiver layer. A dry acceptor layer is brought into contact with the image-forming layer and then separated such that the image-forming layer is adhered to the acceptor layer. It is preferred that the contact of the acceptor layer and the image-forming layer is under heat and pressure and the preferred material for both layers is dry gelatin.
