Abstract
The present invention relates to a method for obtaining a silver halide photographic composition for a coating layer. The method consists in individually preparing the various components of the desired layer, comprising at least one silver halide emulsion, and solutions or dispersions containing one or more finishing addenda and/or gelatin, chilling these components to solidify each of them, cutting them into chunks, cold-blending, in a solid state, the components selected according to the formulation of the desired layer, and liquefying the resulting solid composition just before its introduction into the coating station. The method can be applied to all types of silver halide photographic products, for black and white or color photography.
