| titleOfInvention | ELEMENT AND PROCESS BASED ON PHOTOGRAPHICALLY EFFECTIVE SILVER HALOGENIDS. |
| abstract | New photographic pyrazolone couplers contain at the coupling position a decoupling group represented by the formula (I) in which: L1 and L2 are each methylene or ethylene substituted or unsubstituted; m and n are each 0 or 1; Y is R1 or ZR2; R1 is a substituted or unsubstituted heterocyclic or aryl group, or is a secondary or tertiary carbon group represented by formula (II), in which R3 and R4 are also in the group formed by halogen, R2 and Z1Rb where Z is O, S or NRa; Z1 is O, S or NRc; and R2 is a heterocyclic, aryl or substituted or unsubstituted alkyl group. R5, R6, Ra, Rb and Rc have the definition given in the specifications. R3 optionally binds with at least R4 or R5, forming one or two heterocyclic or acyclic chains, which in turn are optionally substituted; and X represents atoms selected from the group consisting of carbon, oxygen, nitrogen and sulfur atoms sufficient to complete on an unsaturated chain with 5, 6 or 7 members. This chain optionally contains other substituents, in addition to the above mentioned, including other chains fused with the chain containing X. These couplers are useful in elements and photographic methods. |
