    摘要： Novel yellow image dye-forming couplers are disclosed. The couplers comprise an active open-chain keto-methylene group, an anilide group attached to the keto-methylene group, and a cyclic ether group attached to the keto-methylene group. The cyclic ether group comprises two oxygen atoms. Either the anilide group or the cyclic ether may carry a ballast group capable of immobilizing the coupler in the layer in which it is contained. Color photographic elements incorporating the novel couplers are also disclosed.

    摘要： A photographic element including a support bearing a silver halide photographic emulsion and an image dye-forming coupler, wherein the image dye-forming coupler includes a ballasted arylidene pyrazolone which is also a filter dye that upon exposure and processing of the element is destroyed in both exposed and unexposed areas of said element or a masking coupler that upon exposure and processing is destroyed only in exposed areas of the element. The arylidene pyrazolone compound includes an oxygen-inclusive electron donating group in conjugation with the arylidene function, preferably positioned para to the arylidene function.
