Abstract
A colour photographic material which contains at least one pyrrolo[1,2-b]-1,2,4-triazole cyan coupler of the formula (I) in which R1, X and Y have the meaning stated in the description, is distinguished by excellent reproduction of blue and cyan tones if a 2-equivalent yellow coupler is added to the layer containing the couplers of the formula (I).
Claims12
A color photographic print material which comprises at least one red-sensitive silver halide emulsion layer containing at least one cyan coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler and at least one blue-sensitive silver halide emulsion layer containing at least one yellow coupler, which material contains in the red-sensitive layer, of which there is at least one, at least one pyrrolo(1,2-b)-1,2,4-triazole cyan coupler of the formula (I)
- in which
- R1 means hydrogen or a substituent,
- X means a hydrogen atom or a leaving group and
- Y means OR2 or
- wherein
- R2 means
- or alkyl,
- R3 means alkyl,
- R4 means hydrogen or R3,
- R5, R6, R8 and R9 mean are identical or different and are hydrogen or a substituent,
- R7 means a substituent and
- Z means the remaining non-metallic members of a 3- to 8-membered ring, wherein Z may be further substituted,
- wherein a two-equivalent yellow coupler is associated with the red-sensitive layer, of which there is at least one.
