| titleOfInvention | Developer composition and process for developing photographic film |
| abstract | A composition useful as a developer for high-contrast, extremely fine and microfine grain silver halide-containing emulsions comprises at least one 3-pyrazolidone compound, at least one hydroxybenzene compound, and p-methylaminophenol sulfate, at least one accelerator and at least one alkaline preservative. This composition is a semi-compensating, low contrast, fine grain, developer for producing normal contrast photographic negatives from exposed film emulsions generally considered to be capable of reproducing only black or white with repression of almost all gray tones found in normal tone-graduated subjects. |
