| titleOfInvention | Dispersion of leuco compound and silver halide photographic material using the same |
| abstract | PROBLEM TO BE SOLVED: To provide a leuco dispersion having good stability as a silver toning agent, and to provide a pure black tone without deteriorating depiction of a low density portion due to an increase in blue density. Provide an improved silver halide photographic light-sensitive material. SOLUTION: By reacting with an oxidized form of a photographic developing agent, A dispersion of a leuco compound, which has a pH of 3.0 to 5.5 after dispersion of the dispersion of a blue dye or a leuco compound forming a blue pigment. A dispersion wherein the leuco compound is in the form of solid fine particles or a high boiling point solvent. The hydrophilic colloid layer contains a leuco compound which forms a blue dye or a blue dye by reacting with the oxidized form of the photographic developing agent, and the pH of the dispersion of the leuco compound and the aqueous dispersion of gelatin is 4.0 to 4.0. 5.5. A silver halide photographic light-sensitive material, which is 5.5. |
