Abstract
The improved method of processing a silver halide photographic material that has at least one light-sensitive silver halide emulsion layer on one side of a support and which has at least one back coating layer on the other side of the support is characterized in that said silver halide photographic material contains at least one specific dye and at least one anionic surfactant and the development, fixing, washing and/or stabilizing steps are performed within a time period of 40 seconds and at a line speed of at least 1,500 mm/min. The method is capable of processing the silver halide photographic material without producing either substantial or uneven color remnant.
