Color photographic material containing 2-equivalent yellow couplers |
| abstract |
A light-sensitive color photographic material containing at least one silver halide emulsion layer and a 2-equivalent yellow coupler which carries at the coupling position a 5-membered heterocyclic ring with at least one nitrogen atom which nitrogen atom is attached to the coupling position of the yellow coupler and which ring has in the position adjacent to the said nitrogen atom an ethylenic double bond which forms part of an olefinically unsaturated or of an aromatic 5-membered heterocyclic ring, which ring can be split off in the coupling reaction. The new 2-equivalent yellow couplers are easy to prepare, highly reactive and photographically substantially inert. |
