摘要： A method of making a photographic color print using a photographic color material containing low levels of silver halide characterized in that,(a) after image formation and washing and/or stop bath treatment and(b) before non-uniform exposure to adventitious light,the print is uniformly exposed to a light source so that undeveloped silver halide is caused to print out uniformly. Such a uniform density is much more acceptable than a non-uniform density caused by uneven light in normal conditions.

摘要： A process for forming a dye image including the steps of: (a) exposing a photographic element comprising a light sensitive silver halide emulsion layer containing a color coupler compound capable of forming a heat transferable dye upon development; (b) developing the exposed element resulting from step (a) with a color developer solution to form a heat transferable dye image; (c) heating the exposed, developed element resulting from step (b) to thereby transfer the dye image from the emulsion layer to a dye receiving layer which is part of the photographic element or part of a separate dye receiving element brought into contact with the photographic element; and (d) separating the emulsion layer from the dye receiving layer containing the transferred dye image; wherein the color coupler compound is of the following formula (I):COUP--B (I)wherein COUP represents a coupler moiety capable of forming a heat transferable dye upon reaction of the coupler compound with an oxidized product of the developing solution of step (b); and B is hydrogen or a coupling-off group which is separated from COUP upon reaction of the coupler compound with an oxidized product of the developing solution of step (b). The process combines "wet" development with conventional developing solutions and "dry" separation of the developed image from the emulsion layer by heat transfer.

摘要： 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.

摘要： A color transfer imaging element comprising a support having thereon an imaging layer comprising a thermographic, photothermographic, or electrographic material capable of forming an image which absorbs or scatters light or infrared radiation, and a dye layer from which a dye image can be transferred to an image receiver when the imaging element is overall exposed to radiation that is absorbed or scattered by the imaged areas of the imaging layer, thereby causing imagewise heating of the dye. The dye layer is positioned relative to the other layers so as to allow this imagewise transfer of dye to the image receiver.
