PHOTOGRAPHISCHE GELBKUPPLER

摘要

A colour-photographic material contains in at least one layer a yellow coupler of the formula <IMAGE> in which G is a coupler radical bound via the active methylene group to the oxygen atom and Z is the complement required to form a radical with the six-membered ring consisting of the phosphorus atom, the two oxygen atoms and three carbon atoms. With the novel colour-photographic material, photographic images with low fog are obtained.
