2-Equivalent yellow couplers |
| abstract |
Desirable 2-equivalent yellow-forming couplers in which a 1,3-diazolone-2-ring as splittable group is attached by the nitrogen in its 1-position to the coupling position of the 2-equivalent yellow-forming coupler and in which the diazolone ring has a C=C double bond adjacent to the nitrogen atom in its 1-position, have improved photographic properties in particular with respect to improved reactivity on chromogenic development and improved stability of the couplers as well as the dyes produced from them on chromogenic development in a photographic material which has been subjected to storage under moist and/or warm conditions. |
