Process for producing photographic color images |
| abstract |
2-equivalent couplers for forming cyan dye images in color photography of the naphthol type and characterized by a sulfonyl or sulfinyl group in the coupling position are provided. Such couplers have the inherent advantages of 2-equivalent color couplers and, additionally, a high degree of reactivity, little or no tendency to produce stains by nonimagewise coupling and have all of the desirable attributes of prior art cyan-forming couplers. |
