Definitions
- the present invention relates to a method of producing colored photographic images, more particularly such images which are free from unwanted secondary images due to undesired absorptions of the dyestuffs.
- Another means to obtain the desired mask image consists in converting, after color development, the residue of the color coupler into a colored compound with adequate absorption. This often requires supplementary baths and has in no case given satisfactory results.
- the oxidizing substance can be present in a special bath or in one of the baths normally used.
- the oxidizing substance normally present in the bleaching bath is used.
- the mask-forming compound can be present in a bath between the color developer and the bleaching bath, or in one of the sensitive or non-sensitive layers of the photographic material. It may be advantageous that it be fast to difiusion and preferably it corresponds to the following general formula:
- R hydrogen or any substituent, e.g. alkyl including aralkyl, aryl, carboxyl including esterified carboxyl or amino including acyl amino;
- R alky1 including aralkyl, aryl, or a heterocyclic residue
- Mask-forming compounds are for instance:
- EXAIVIPLE 1 A strip of negative multilayer material, the underlying red-sensitive layer of which contains l-hydroxy-Z- naphthoic acid hexadecylarnide-4-sulphonic acid as color coupler is exposed to a wedge through a red-filter. This exposed film is successively: color developed in a devel- I oper containing N:N diethyl para phenylenediamine, fixed, rinsed, treated for 2 minutes in a bath composed of:
- EXAMPLE 2 A film support is coated with an emulsion layer which besides theusual red sensitizer and l-hydroxy-Z-naphthoic acid-hexadecylamide-4-sulphonic acid as color coupler also contains 2-(p-alpha-hexadecenyl-succinyl-imidophenyl) -3-1nethyl-4-aminopyrazolone-5.
- a strip or" this film is exposed through a wedge and after color development, fixed, rinsed, bleached in the same bath as in Example 1, fixed, rinsed and dried. On measurement, a decrease of the greenand blue-filter densities is observed for an increase of the red-filter densities, not observed in a test strip containing no pyrazolone derivative.
- EXAMPLE 3 A film support is coated with an emulsion layer which besides a green sensitizer and 4-hexadecenyl-succinylimido-indazolone as color coupler also contains 2-(p-hexadecenylsuccinylimidophenyl) -3-methyl-4-amino pyrazolone-5. After exposure of a strip as in Example 1, color development, fixing, rinsing, bleaching for instance in a bath mentioned in Example 1, again fixing, rinsing and drying, at strong yellow-brown color is observed all over the surface. On measurement of the wedge, a much greater proportion of green to blue-filter density than in a comparable material coated without the pyrazolone derivative is observed.
- Photographic element having superposed silver halide emulsion layers sensitive to different regions of the visible spectrum, at least one of said layers containing a color coupler for color development, which is reactive with the oxidation product of an aromatic amino developing agent to form by color development a primary dye image which absorbs a major proportion of light in one region of the visible spectrum, and undesirably absorbs a minor proportion of light in at least one other region of the visible spectrum, at least said one layer also containing a 4-amino-5-pyrazolone derivative of the formula l Ra wherein R is a member selected from the group consisting of alkyl, phenyl, and benzoylamido, R is a member selected from the group consisting of alkyl, phenyl, and p-(a-hexadecenyl-succinyl-amido)-phenyl, R is a member selected from the group consisting of hydrogen, phenyl, and p-(succinyl-amido-methylest
