Abstract

920,310. Photographic development. TECHNICOLOR CORPORATION. May 1, 1961 [May 17, 1960], No. 15659/61. Drawings to Specification. Class 98 (2). An exposed photographic silver halide emulsion layer is developed by impregnating the layer with a first developing reagent during recurrent intervals, and during alternate intervals impregnating the layer with a second developing reagent which with the first reagent produces an active developer in the emulsion layer. The first reagent may be a developing agent inhibited with an acid, and the second reagent may be an alkali. The film may be rinsed between successive immersions in solutions of the reagents and superficial liquid removed.
