Abstract
Abstract A method for rapidly processing a silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer and a silver halide photographic material therefor are disclosed. The total amount of binder on one side of the support is not more than 3.0 g/m 2 , the photographic materials contains in at least one layer at least one compound selected from the group consisting of compounds represented by formulae (I) and (II): ##STR1## wherein X 1 , X 2 , A, R 11 , R 12 , R 13 , R 14 , R 15 , and R 16 are defined in the specification. Processing may be effected in a total processing time of from 15 to 45 seconds. Pressure sensitivity can be reduced without reducing photographic speed.
