Definitions
- Fog is reduced and speed is maintained during development of v light-sensitive color photographic materials which comprise at [30] Foregn Apphcauon Pmmty Data least one of certain mercaptotetrazole compounds and at least July 10, 1969 Japan ..44/541 16 one of Several hydwquinone compounds.
- the present invention relates to a light-sensitive color -5 (ll-3 (i H photographic material free from formation of fog due to color i; l development and further free from degradation in speed.
- a color photographic material is composed of emulsion layers larger in number than those in the case of a white-black (1)1 film, so that the thickness of the overall emulsion layer Q becomes great to bring about such a drawback that the resulting image is deteriorated in sharpness.
- the (1H thickness of each layer As thin as possible. If the thickness of (fl-- -NOs 11 each layer is desired to be made thin, the color density should i H necessarily be increased, and thus there are required such means as to increase the contents of coupler and silver halide, Ni with the result that fog is liable to be formed at the time of (1)43 color development.
- the amount of fog increases when f fi' S n the temperature or the pH of color developer is increased in N N order to develop the photographic material quickly.
- 01 ⁇ N/ For the prevention of fog due to color development, there have been used a tetrazaindene compound or a compound (D4 Q having a mercapto group.
- the former is insufficient II in fog-inhibiting effect and hence cannot be put into practical use.
- the latter can inhibit the formation of'fog due to l g p N 7 color development of light-sensitive silver halide, it undesirably brings about severe decrease in speed.
- R R and R are individually a hydrogen atom, an (ll-13 CH N C an alkyl aryl or aralkyl group, provided that R, and R; may be same or different, and at least one hydroquinone compound represented by the general formula (II):
- Both the compounds (I) and compounds (ll) of the present invention may be used in admixture of two or more so as to be in conform to the purpose of application of the resulting photographic materials.
- the compounds (I) and (ll) may be incorporated into one layer or may separately be incorporated into adjacent layers. These compounds may be incorporated not only into emulsion layers but also into auxiliary layers such as sub layer, inter layer, protective layer and the like.
- the compounds may be added to a silver halide emulsion at any stage during the preparation thereof, but it is more effective to add the compounds at a stage during the second ripening or a stage prior to coating the emulsion to a support.
- the amounts of the compounds to be added are not particularly limited, and the optimum amounts thereof vary depending on the kinds of the compounds. Generally, however, the amounts of the compounds (I) and (ll) are preferably 10 to 10" moles and 10 to 10* moles, respectively, per mole of silver halide.
- the compounds (I) and (ll) those which are lipophilic are added in the form of solutions in a high boiling organic solvent such as dibutyl phthalate or the like or in a low boiling organic solvent such as chlorofomi, acetone, dimethylformamide or the like, while those which are watersoluble are added in the form of solutions in a water-miscible organic solvent or an aqueous alkali solution.
- the photographic emulsion used in the present invention include AgCl, AgBr, AgClBr, AgBrl and the like.
- the emulsion may be optically sensitization treatment with a cyanine or merocyanine dye or to chemically sensitized treatment with a sulfur-containing compound (sodium thiosulfate), noble metal salt (gold chloride), polyalkylene oxide derivative, reducing compound or the like.
- the emulsion may have been incorporated with such a hardener as formalin and such a coating aid as a synthetic or natural surface active agent, e.g., saponin.
- the color couplers which are used in the present invention are those which develop colors through the reaction with a p-phenylenediamine color developer.
- a yellow coupler having a benzoylacetanilide group there may be used a yellow coupler having a benzoylacetanilide group, a magenta coupler having a pyrazolone or indazolone group, and a cyan coupler having a phenol or naphthol group.
- These couplers may contain in the active methyleneor methine-portion a substituent capable of releasing by color development reaction, e.g., a halogen or an arylazo, aryloxy or the like group.
- the couplers may contain in the molecule either one or both of a ballasting group, e.g. a long chain alkyl group or an alkylphenoxy group,
- a water-solubilizing group e.g., a sulfonic group or a carboxyl group.
- couplers those which are lipophilic may be brought into the form of solutions in a high boiling organic solvent, e.g., dibutyl phthalate, or in a low boiling organic solvent, e.g., chloroform, acetone or dimethylformamide, while those which are water-soluble may be brought into the form of solutions in an alkali or the like, and the solutions may be added directly to a silver halide emulsion or added to a color developer.
- a high boiling organic solvent e.g., dibutyl phthalate
- a low boiling organic solvent e.g., chloroform, acetone or dimethylformamide
- water-soluble may be brought into the form of solutions in an alkali or the like, and the solutions may be added directly to a silver halide emulsion or added to a color developer.
- the light-sensitive layer of the photographic material according to the present invention is composed of, from the top layer, a protective layer, a yellow layer, a yellow filter layer, a magenta layer, an inter layer, a cyan layer, an antihalation layer and a support in this order.
- the light-sensitive layer may be composed of a magenta layer, a cyan layer and a yellow layer in this order. in each case, the photographic material can be used effectively.
- the support employed in the present invention includes natural and synthetic polymer films such as cellulose acetate or polyester film.
- Typical examples of the color developing agent used for the development of the present light-sensitive photographic materials are sulfates, hydrochlorides and sulfites of N,N- diethyl-p-phenylenediamine, N-ethyl-N-hydroxyethyl-p-phenylenediamine, N-ethyl-N-hydroxyethyl-2-methyl-p-phenylenediamine, N-ethyLB-N-methanesulfonamidoethyl-3- methyl-4-aminoaniline, and the like.
- EXAMPLE 1 A high-speed silver bromoiodide photographic emulsion (containing 5.0 mole of Ag! and 180 g./mole AgX of gelatine) was incorporated with 2.5Xl moles/mole AgX of a sensitizing dye having the structure set forth below to prepare a red light-sensitive emulsion.
