Definitions
- the present invention relates to a silver halide color photographic material. More particularly, the present invention relates to a silver halide color photographic material comprising yellow colored cyan couplers and pyrazoloazole couplers.
- light-sensitive material One of the properties required for silver halide color photographic materials (hereinafter simply referred to as "light-sensitive material” as necessary) is color reproductivity.
- Couplers are used in, e.g., color negative light-sensitive materials for picture taking, to correct for undesired absorption of colored dye images.
- These colored couplers are disclosed in many publications and patents, for instance Research Disclosure No. 17643, VII-G.
- Colored couplers used for the correction of undesired absorption of cyan images include those which exhibit a maximum absorption wavelength between about 500 nm and 600 nm in the visible light range and undergo a coupling reaction with an oxidation product of an aromatic primary amine developing agent to form a cyan dye image which exhibits a maximum absorption wavelength between about 630 nm and 750 nm.
- a cyan dye image also has an absorption in the visible light range of 400 to 500 nm. If these undesired absorptions are also corrected for by the so-called yellow-colored cyan couplers, an effect which photographically approximates the interimage effect developed from a cyan colored image layer and a yellow colored image layer can be obtained, probably providing an advantage in color reproduction.
- JP-A-61-221748 and JP-A-1-319774 the term "JP-A" as used herein means an "unexamined published Japanese patent application").
- this appoach does not necessarily provide satisfactory properties, due to its low coupling reactivity and small molecular extinction coefficient.
- This approach is also disadvantageous in that photographic properties such as the preservability of light-sensitive material and the stability of latent images are subject to great fluctuation. Thus, this approach is not yet suitable for practical use.
- Magenta couplers for color negative light-sensitive materials for picture taking include, primarily, 5-pyrazolone couplers.
- color negative light-sensitive materials for picture taking usually comprise yellow colored magenta couplers to correct for the undesired absorbption.
- pyrazoloazole couplers have been rapidly developed.
- Examples of such pyrazoloazole couplers include pyrazolotriazole couplers described in U.S. Patents 3,725,067, 4,562,146, 4,607,002, 4,675,280, 4,840,886, 4,621,046, and 4,659,652, and JP-A-61-65243, JP-A-61-65245, JP-A-61-65246, and JP-A-61-65247, pyrazolotetrazole couplers as described in JP-A-60-33552, and pyrazolopyrazole couplers as described in JP-A-60-43659.
- couplers provide colored images having colors ranging from magenta to cyan depending on the substituents incorporated therein. These colored images exhibit no secondary absorption peak in the short wavelength range as observed in the absorption spectrum of colored images obtained from the above mentioned 5-pyrazolone couplers. These colored images have the further great advantage that they exhibit a small absorbance in the short wavelength side in the blue light range. Thus, these couplers can be said to exhibit excellent color reproductivity.
- couplers are disadvantageous in that they do not provide a high coupling reactivity and are subject to great fluctuation in photographic properties after storage at elevated temperature and humidity after preparation of light-sensitive material or after storage at elevated temperature and humidity for a prolonged period of time between the time of picture taking and development. This makes it difficult to put this approach into practical use.
- a silver halide color photographic material comprising a support having thereon (i) at least a silver halide emulsion layer (ii) a yellow-colored cyan coupler capable of undergoing a reaction with an oxidation product of an aromatic primary amine developing agent to release a group containing a water-soluble 6-hydroxy-2-pyridon-5-ylazo group, a water soluble 2-acylaminophenylazo group, a water soluble 2-sulfonamidophenylazo group, a water soluble 5-aminopyrazol-4-ylazo group or a water soluble pyrazolon-4-ylazo group and (iii) a coupler represented by the general formula (A): wherein R a1 represents a hydrogen atom or substituent; Xa1 represents a hydrogen atom or a group capable of being separated therefrom upon a coupling reaction with an oxidation product of an aromatic primary amine developing agent; Za, Zb and Z
- the yellow-colored cyan coupler to be used in the present invention will be further described hereinafter.
- the yellow colored cyan coupler of the present invention is a cyan coupler which exhibits a maximum absorption wavelength between 400 nm and 500 nm in the visible absorption range and undergoes coupling with an oxidation product of an aromatic primary amine developing agent to form a cyan dye having a maximum absorption wavelength between 630 nm and 750 nm in the visible absorption range.
