Abstract
Abstract A novel method for processing a silver halide color photographic material is provided, which comprises processing a silver halide color photographic material having at least one silver halide emulsion layer on a reflective support with a color-developing solution substantially free of benzyl alcohol and containing at least one compound represented by formula (I) ##STR1## wherein R 1 represents a hydrogen atom, --CH 2 COOH, or ##STR2## R 2 represents a hydrogen atom or --COOH; n represents an integer of 0 or 1; and Z represents atoms necessary for the formation of an aromatic ring.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
125 words
A method for continuous processing silver halide color photographic material, which comprises processing a silver halide color photographic material having at least one silver halide emulsion layer on a reflective support with a color-developing solution containing benzyl alcohol in a concentration of 0.5 ml/l or less, and containing at least one compound represented by formula (I) ##STR29## wherein R 1 represents a hydrogen atom, --CH 2 COOH, or ##STR30## R 2 represents a hydrogen atom of --COOH: n represents an integer of 0 or 1; and Z represents atoms necessary for the formation of an aromatic ring; and subsequent to color-developing, bleach-fixing said material for a time of 1 minute or less and then rinsing said material for a time of 2 minutes or less.
Claim 2
Independent Claim
125 words
A method for continuous processing silver halide color photographic material, which comprises processing a silver halide color photographic material having at least one silver halide emulsion layer on a reflective support with a color-developing solution containing benzyl alcohol in a concentration of 0.5 ml/l or less, and containing at least one compound represented by formula (I) ##STR29## wherein R 1 represents a hydrogen atom, --CH 2 COOH, or ##STR30## R 2 represents a hydrogen atom of --COOH: n represents an integer of 0 or 1; and Z represents atoms necessary for the formation of an aromatic ring; and subsequent to color-developing, bleach-fixing said material for a time of 1 minute or less and then rinsing said material for a time of 2 minutes or less.
