Definitions
- coupler-in-emulsion type color sensitive materials which contain silver halide and color formers (hereinafter referred to as a coupler) which form dyes by reacting with an oxidation product of an aromatic amino photographic developing agent in the photographic emulsion layers, and coupler-in-developer type color sensitive materials which do not contain couplers in the photographic emulsion layers.
- the present invention relates to such a coupler-in-developer type color sensitive material.
- the following treatments are usually practiced in turn after exposing to light, that is, monochromatic white-black development, exposing to a red light at the support side of the sensitive material, cyan color development by a cyan color developer containing a cyan coupler and an aromatic amino photographic developing agent, exposing to a violet light at the emulsion side, yellow development by a yellow color developer containing a yellow coupler and an aromatic amino photographic developing agent, and magenta color development by a magenta color developer containing a magenta coupler and an aromatic amino photographic developing agent.
- the present invention relates to a new process for improving the density of reversal color images in the cyan color development, yellow color development and magenta color development, and especially to a new process for improving the density of the magenta color image.
- a more efiicient color reproduction system can be produced by increasing the density produced in the reversal color images. If the same density is kept, thinner emulsion layers can be produced and consequently it is possible to improve sharpness and to decrease the amount of silver halide in the emulsion layers.
- the new process by this invention for improving the density of the reversal color images comprises treating a silver halide gelatin emulsion containing the following water-soluble polymer as the binder with color developing solutions containing color couplers.
- the water-soluble polymers used for the above-mentioned which have been discovered by the present inventors, are those having a a repeating unit structure represented by the following formula:
- x is within the range 50gx 100, preferably which represents a ratio of both blocks represented by the above-mentioned rational formula.
- Preferable polymers among these polymers are those having a number average molecular weight in a range of 5,000-200,000, especially 20,000100,000.
- the water-soluble polymer used in the present invention may be added solely to a gelatin emulsion or may be added by substituting a part of the gelatin in the emulsion. Though addition of the water-soluble polymer may take place at any step before coating the emulsion, it is preferable to add it any time from after ripening to coating.
- the amount of the polymer used in the present invention is preferably in a range of 1%90%, especially 5%50%, by weight, based on the combined weight of gelatin and said copolymers.
- the gelatin emulsion contans silver iodide bromide as the silver halide.
- the silver halide emulsion may be sensitized by compounds which contain labile sulfur such as a sodium thiosulfate and allyl thiourea etc., and/or complex salts such as this cyanato aurite, and/or reduction sensitizers such as amino compounds and stannous chloride (refer to The Theory of the Photographic Process, 3rd edition, Macmillan Company, New York (1966), pages 113-116), and/or polyalkyleneoxide derivatives.
- the emulsion may include sensitizing dyes which sensitize a wave length range of 500-700 nm, for example, 1,1- diethyl-2,2'-cyanine iodide and 3,3-diethyl 9 methylcarbocyanine iodide (refer to the above-mentioned literature reference, pages 199-232).
- the emulsions may include stabilizers such as 4-hydroxy-6-methy1 1,3,3a,7 tetrazaindene (refer to the above-mentioned literature reference, pages 344-346), hardeners such as formaldehyde and mucobromic acid (the same literature reference, pages 54-60) and wetting agents such as saponin and sodium alkylbenzene sulfonate.
- stabilizers such as 4-hydroxy-6-methy1 1,3,3a,7 tetrazaindene (refer to the above-mentioned literature reference, pages 344-346)
- hardeners such as formaldehyde and mucobromic acid (the same literature reference, pages 54-60)
- wetting agents such as saponin and sodium alkylbenzene sulfonate.
- the multilayer color photographic material comprising silver halide gelatin emulsions which contain the water-soluble polymer is carried out by a common reversal color processing for the coupler-in-developer type sensitive material. Namely, at least a color developing agent and a diffusi ble coupler which colors in cyan, magenta or yellow are included in each color developer.
- the color developing agent there are used well-known paraphenylenediamine derivatives such as 4-amino-N,N- diethylaniline, 4 amino-N,N-diethyl 3 methylaniline, 4 amino 3 methyl-N-methyl-N- (B-methylsulfonamidethyl) aniline and 4 amino-B-methyI-N-ethyl-N-(fi-hydroxyethyl) aniline (refer to the above-mentioned literature reference, page 387).
- paraphenylenediamine derivatives such as 4-amino-N,N- diethylaniline, 4 amino-N,N-diethyl 3 methylaniline, 4 amino 3 methyl-N-methyl-N- (B-methylsulfonamidethyl) aniline and 4 amino-B-methyI-N-ethyl-N-(fi-hydroxyethyl) aniline (refer to the above-mentioned literature reference, page 387).
- the diffusible cyan coupler there are used'wellknown phenolic couplers such as 2 chloro l-naphthol, 2,4 dichloro 1 naphthol, 2 (o-acetamide-fi-phenyD- l-hydroxy naphthamide, etc. (refer to above-mentioned literature reference, page 387).
- the difiusible magenta coupler there are used openchain methylene type couplers such as amylacetonitrile, 2 cyanoethyl benzofuran and benzylacetonitrile and cyclic methylene couplers such as 1 phenyl 3 (4-chlorobenzamido) 5 pyrazolone, 1 phenyl 3 (3-nitrobenzoylamino) 5 pyrazolone and 1-(2,4,6-trichlorophenyl) 3 (4 nitroanilino)-5-pyrazolone.
- openchain methylene type couplers such as amylacetonitrile, 2 cyanoethyl benzofuran and benzylacetonitrile
- cyclic methylene couplers such as 1 phenyl 3 (4-chlorobenzamido) 5 pyrazolone, 1 phenyl 3 (3-nitrobenzoylamino) 5 pyrazolone and 1-(2,4,6-trichloroph
- acylacetamide type open-chain methylene couplers such as 2 acetanilide, 2 aceto 2', 4' dichloroacetanilide, 2 benzoyl-acetanilide, 2 tbenzoyl 2'-methoxyacetanilide and 2 methyl 4 (methyl sulfonamide-ethyl) ethylaniline (refer to the above-mentioned literature reference, page 389 and G. H. Brown et al., Journal of the American Chemical Society, 79, pages 2917-2927 (1957)).

- Example 1 the ratio (by weight) of silver bromoiodide to the binder in the initial emulsion was 6 g. of binder (100% gelatin)/11 g. of silver iodide bromide.
- the gelatin of this binder was substituted by a vinyl acetate-vinyl alcohol copolymer in many ratios. Results are shown in Table 1.
- the cyan and yellow developers had the following compositions:
- YELLOW DEVELOPER Sodium sulfite ..g 5.0 N,N'-diethyl paraphenylenediamine hydrochloride g 1.2 Sodium carbonate (monohydrate) ..g 20.0 Potassium bromide g 0.3 0.1% potassium iodide cc 20 Z-benzoyl-(4'-parato1uenesulfonamide) acetanilide g 1.0 Sodium hydroxide g 4.0 Water to make 1 liter.
- a photographic reversal color process employing a photographic element containing three photographic silver halide emulsion layers, comprising first exposing said element to light to produce a latent image therein, developing the exposed element in a photographic black and white developer to produce a black and white negative image, exposing the element to a light of a color to which the first exposed silver halide emulsion layer is sensitive, and developing the resulting element in a color developer for producing a colored image, said color developer containing an aromatic primary amino color developing agent and a photographic color coupler selected from the group consisting of a magenta-forming pyrazolone color coupler, a cyan-forming phenolic color coupler and a yellow-forming open chain keto-methylene color coupler, the improvement which comprises utilizing a binder for said silver halide comprising gelatin and a water-soluble copolymer having a number average molecular weight of from about 5,000 to about 200,000 having repeating units represented by the formula:
- gelatino silver halide emulsion layer to which said copolymer is added is a magenta color-forming emulsion layer.
