The protective overcoat is formed by providing a photographic element having at least one silver halide light-sensitive emulsion layer; and applying an aqueous coating comprising polymer particles having an average size of 0.1 to 50 microns at a weight percent of 5 to 50 percent, a soft polymer latex binder at a weight percent of 1 to 3 percent, over the at least one silver halide light-sensitive emulsion layer. The silver halide light sensitive emulsion layer is developed to provide an imaged photographic element. The hydrophobic polymer particles is fused to form a protective overcoat.Type: GrantFiled: July 23, 1997Date of Patent: December 29, 1998Assignee: Eastman Kodak CompanyInventors: Anne E. Bohan, Vito A. DePalma, William K. Goebel, Amy E. Jasek, Thomas H. Whitesides

Patent number: 5766830Abstract: A method for processing an exposed black and white silver halide photographic light-sensitive material includes the steps of: (1) developing the exposed light-sensitive material with a developing solution, (2) fixing the developed material with a fixing solution, (3) washing the fixed material with water which is replenished in an amount of from 0 to 3 liter/m.sup.2 of the exposed light-sensitive material, and (4) drying the washed material. The developing solution is replenished with a solid photographic composition. This solid photographic composition includes a developing agent selected from the group of a dihydroxybenzene developing agent represented by Formula I and a developing agent represented by Formula II (provided that the developing agent represented by Formula II may form a sodium salt, a potassium salt or a lithium salt). Formulae I and II are as follows: ##STR1## In the formulae, R.sub.1, R.sub.2, R.sub.3, and R.sub.Type: GrantFiled: February 26, 1997Date of Patent: June 16, 1998Assignee: Konica CorporationInventors: Akira Shimizu, Shoji Nishio, Yasunori Wada, Iku Metoki
