Abstract
Abstract A development method which comprises developing a silver halide photographic ligh-sensitive material in the presence of a compound represented by the following general formula: ##STR1## wherein R 1 , R 2 , R 3 , R 4 and R 5 each represent a hydrogen atom, alklyl group, alkenyl group, aralkyl group or aryl group, X represents an anion, and P is 1 or 2.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
66 words
A method of developing a silver halide photographic light-sensitive material which comprises imagewise exposing said material to light, developing the photographic light-sensitive material with a silver halide developing agent in the presence of a compound selected from the group consisting of ##STR11## said compound being present in a bath prior to development, the developer bath, or a silver halide emulsion layer of the photographic light-sensitive material.
Claim 2
Independent Claim
66 words
A method of developing a silver halide photographic light-sensitive material which comprises imagewise exposing said material to light, developing the photographic light-sensitive material with a silver halide developing agent in the presence of a compound selected from the group consisting of ##STR11## said compound being present in a bath prior to development, the developer bath, or a silver halide emulsion layer of the photographic light-sensitive material.
