ABSTRACT:
A method for processing silver halide photographic materials comprising the step of: processing imagewise exposed silver halide photographic material using a developer containing at least one compound represented by general formula (X): ##STR1## wherein R.sub.1 and R.sub.2 each represents a hydrogen atom, an alkyl group containing from 2 to 8 carbon atoms, an alkenyl group containing from 3 to 8 carbon atoms, or an aralkyl group containing from 7 to 12 carbon atoms; or R.sub.1 and R.sub.2 are combined to form a ring; R.sub.3, R.sub.4, R.sub.5, and R.sub.6 each represents a hydrogen atom, or an alkyl group containing from 1 to 4 carbon atoms: and n represents an integer from 3 to 20. A developer for processing silver halide photographic materials comprising at least one compound represented by general formula (X), described above. A silver halide photographic material comprising: at least one compound represented by general formula (X'): ##STR2## wherein R'.sub.1 and R'.sub.2 each represents a hydrogen atom, an alkyl group containing from 1 to 30 carbon atoms, an alkenyl group containing from 3 to 30 carbon atoms, or an aralkyl group containing from 7 to 30 carbon atoms; or R'.sub.1 and R'.sub.2 are combined to form a ring; R.sub.3, R.sub.4, R.sub.5, and R.sub.6 are the same as described above; and n' represents an integer from 2 to 50. A method for processing silver halide photographic materials comprising the step of: processing imagewise exposed silver halide photographic material comprising at least one compound represented by general formula (X'), described above.
