Definitions
- the present invention concerns a color development of a coupler-free type reversal multilayer color photographic sensitive material and especially to a process for increasing an amount of dye produced in reversal color images.
- the following treatments are usually practiced in turn after exposing to light, that is, monochromatic white-black development, exposing to a red light at a support side of the sensitive material, cyan color development by a cyan color developer containing a cyan coupler and an aromatic amine photographic developing agent, exposing to a violet light at an emulsion side, yellow development by a yellow color developer containing a yellow coupler and an aromatic amine photographic developing agent, and magenta color development by a magenta color developer contain- 7 3,745,007 Patented July 10, 1973 ice SUMMARY OF THE INVENTION Detailed description of the invention
- the present invention concerns 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 magenta color images.
- the present invention it is possible to obtain a more efiicient color reproduction system and to produce a thinner emulsion layer by increasing the density obtained in the reversal color images. Accordingly, it is possible to improve sharpness and to econimize silver halide in the emulsion layer.
- the new process for improving the density of the reversal color images by the present invention comprises treating a silver halide gelatin emulsion containing the following water soluble polymer as the binder with color developer containing color couplers.
- the water soluble polymers used for the above-mentioned object which have been found out by'these inventors, are those having a repeated unit structure represented by the following formula:
- R2 latnltoflta R hydrogen atom or methyl group
- X is a range of x 210 which represents a ratio of both blocks represented by the above-mentioned rational formula. When x: 100, it represents polyacrylarnide.
- Especially preferable polymers among these polymers are those having a number average molecular weight in a range of SWIG-3,000,000. (Abbreviated as n.a.m.w.)
- water soluble polymers used are shown, as exemplary, and not as limiting.
- Methacrylamide-rnethacryliccopolymer (preferably 10,000-200,000 in n.a.m.w.)
- Methacrylamide-ethyl methacrylate copolymer (preferably 10,000-200,000 in n.a.m.w.)
- X is greater or equal 75 and smaller or equal 95 concerning from water soluble polymers 2 to 6.
- 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 gelatin in the emulsion. Though addition of the water soluble polymer may take place at any step before coating of the emulsion, it is preferable to add at the step from afterripening to coating.
- a preferable amount is in a range of 1%90% particularly 50% (by weight) based on the combined amount (weight) of said gelatin and said copolymer.
- the silver halide emulsion may be sensitized by compounds which contain labili sulfur such as sodium thiosulfate and allyl thiourea etc., and/or complex salts of monovalent 'gold and thiocyanic acid, and/ or reduction sensitizers such as amino compounds and stannous chloride (refer to The Theory of the Photographic Process: 3rd edition; McMillan Company, New York (1966), pages 113- 116), and/or polyalkylene oxide derivatives.
- the emulsion may include sensitizing dyes which sensitize a wavelength range of 500-700 me, for example, 1,1'-diethyl-2,2'-cyanine iodide and 3,3'-diethy1-9-methyl carbocyanine iodide (refer to the above-mentioned literature, pages 199-232).
- the emulsion may include stabilizers such as 4-hydroxy-6- methyl-l,3,3a,7-tetrazaindene (refer to the same literature, pages 344-346), hardeners such as formaldehyde and mucobromic acid (refer to the same literature, pages 54- 60) and a wetting agents such as saponin and sodium alkylbenzene sulfonate.
- stabilizers such as 4-hydroxy-6- methyl-l,3,3a,7-tetrazaindene (refer to the same literature, pages 344-346)
- hardeners such as formaldehyde and mucobromic acid (refer to the same literature, pages 54- 60)
- a wetting agents such as saponin and sodium alkylbenzene sulfonate.
- the multilayer color photographic material containing silver halide gelatin emulsions which contain a water soluble polymer is carried out by a common reversal color precessing for the coupler-free type sensitive material. Namely, at least a color developing agent and a dilfusible coupler for cyan, magenta or yellow are included in each color developer.
- the color developing agent there are used well-known paraphenylenediarnine derivatives such as 4amino-N,N-diethyl-aniline, 4-amino- N,N-diethyl-3-methylaniline, 4-amino-3-methyl-N-methyl- N (B methylsulfoanmidoethyDaniline and 4-amino-3- methyl-N-ethyl-NQfi-hydroxyethyl) aniline, etc. (refer to the above mentioned literature, page 387).

- EXAMPLE 1 After melting by heating a high-sensitive gelatino silver bromoiodide reversal color emulsion which was sulfursensitized and gold-sensitized (content of silver iodide: 3.5% by mol), it was wetted to a cellulose triacetate film base. Couplers were not included in the emulsion.
- the binder of the silver bromoiodide in the coated emulsion was gelatin which contained polyacrylamide (molecular weight: 3,000,000, and molecular weight: 490,000) in many ratios.
- This emulsion layer was exposed to light by using a NSG II type sensitometer and processed to the following treatments.
- Formulations of the cyan color developer and the yellow color developer used are as follows.
- said color developer containing an aromatic primary amine color developing agent and a photographic color coupler selected from the group consisting of a magenta forming pyrazolone color coupler, a cyan forming phenolic coupler, and a yellow forming open chain kctomethylene color coupler, the improvement which comprises:
- a binder for said silver halide consisting essentially of a gelatin and a water-soluble copolymer exhibiting a molecular weight ranging from 5,000 to 3,000,000, characterized as containing as a repeating unit within said copolymer, a structure of the following formula:
