Abstract
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.
