发明名称 Boundary control of developer diffusion in photographic elements.
摘要 <p>A method of forming a chromogenic photographic image comprising the steps of: providing an aqueous developable photographic element coated on a single dimensionally stable support, wherein said element comprises in reactive association (1) a developing agent, where said developing agent is a primary amine or a precursor of a primary amine, (2) radiation sensitive silver halide, (3) a color coupler compound that forms or releases a dye upon reaction with the oxidation product of a primary amine developing agent, and (4) a hydrophilic binder; exposing said element to actinic radiation; and developing said image by contacting said element with an applied volume of an aqueous processing solution, wherein said applied volume is limited to less than 800% of the swell volume of said element in equilibrium-mechanical contact with said processing solution or the temporal duration of said contacting is limited to a time less than 500% of the time necessary for said element to swell to 90% of said swell volume. Also, an aqueous developable chromogenic photographic element coated on a single dimensionally stable support wherein said element comprises in reactive association (1) a developing agent, where said developing agent is a primary amine or a precursor of a primary amine, (2) radiation sensitive silver halide, (3) a color coupler compound that forms or releases a dye upon reaction with the oxidation product of a primary amine developing agent, (4) a hydrophilic binder, and (5) one or more contiguous overcoat layers devoid of silver halide and devoid of developer or developer precursor wherein said overcoat layers comprise hydrophilic binder at a level of at least 3 g/m<2>.</p>
