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.
Claims35
A method of imaging comprising forming an image in at least one image-forming layer of a donor-receiver element, allowing said image to diffuse to a receiver layer in said donor-receiver element, bringing a dry acceptor layer of a removal element into contact with said donor-receiver element, and separating said removal element from said donor-receiver element such that said image-forming layer is adhered to said acceptor layer and wherein said acceptor layer comprises less than 15 percent by weight water.
A method of imaging comprising forming an image in an imaging layer of a donor-receiver element, said donor-receiver element comprising an upper dry gelatin containing layer, allowing said image to diffuse to a receiver layer of said donor-receiver element, bringing a dry gelatin acceptor layer of a removal element into contact with the upper dry gelatin containing layer of said donor-receiver element with heating and pressure, and separating said donor-receiver element and said removal element such that said imaging layer is adhered to said acceptor layer and separates from said image receiver layer.
A method of delaminating donor-receiver layers in a dry donor-receiver photographic element, wherein said element comprises a plurality of image forming layers and an image receiving layer, said method comprising bringing a dry acceptor layer of a removal element into contact with said donor-receiver element, and separating said removal element from said donor-receiver element such that said image forming layers adhere to said acceptor layer, such that said image receiver layers are separated from said image forming layers, and wherein said acceptor layer comprises less than 15 percent by weight water.
