| titleOfInvention | Photographic coupler having ballast containing sulfone or sulfoxide groups |
| abstract | (57) [Summary] [Objective] It shows increased coupler reactivity, improved contrast and improved development speed, and also gives maximum dye density and shows sufficient solubility, dispersibility and deep color hue. Provide a new coupler. ## STR1 ## Formula (I): (In the formula, K is a pyrazolone to which a ballast group is bonded, Novel photographic silver halide materials containing dye-forming couplers represented by phenol, naphthol, enamine or acylacetamide based coupler units) are useful in photographic materials and processing. The contained couplers exhibit increased coupler activity and provide improved maximum magenta image dye density, contrast and development speed. |
