Definitions
- a color photographic silver halide light-sensitive material comprising a support having a silver halide light-sensitive emulsion layer thereon wherein a copolymer is incorporated in said light-sensitive emulsion layer or a non-light-sensitive auxiliary layer on said support, said copolymer being represented by the following formula:
- R represents hydrogen or methyl
- R represents hydrogen, methyl, ethyl, propyl or butyl
- R represents hydrogen, methyl, ethyl, propyl or butyl
- x/y varies from 95/5 to 20/80.
- This invention relates to a color photographic light-sensitive material. More particularly, it relates to a color photographic light-sensitive material of improved silver bleaching property.
- a color photographic light-sensitive material When a color photographic light-sensitive material is subjected to exposure and then to color development, a color image and a silver image are formed. The silver image is then removed by a silver bleaching treatment and a fixing treatment, thus obtaining only a dye image. If the step of silver bleaching is incomplete, however, a part of the silver image remains in the material. Such an occluded silver cloud makes the color photographic image obscure and remarkably degrades the color reproduction.
- Some methods have been proposed in order to improve the silver bleaching property. It is well known to incorporate some compounds in a color photographic light-sensitive material for the purpose of preventing such silver occlusion.
- a polymer containing vinylpyrrolidone is described as a silver occlusion inhibitor in British Pat. No. 1,052,487.
- the compound described in this patent has the disadvantage that the development of exposed silver halide grains is markedly suppressed so that a long time is necessary for development, although it has an effect of improving the silver removal.
- the above-mentioned object can be accomplished by incorporating in a color photographic light-sensitive material a copolymer of 2-(N-acyl)aminoethyl acrylate or 2-(N- acyl)aminoethyl methacrylate and N-vinylpyrrolidone.
- the non-lightsensitive auxiliary layer is a layer adjacent to the light-sensitive emulsion layer, for example, a protective layer, an intermediate layer, a filter layer or antihalation layer.
- the effect of the copolymer of N-vinylpyrrolidone and 2- (N-acyl) aminoethyl acrylate or 2-(N-acyl)aminoethyl methacrylate depends on its monomer ratio.
- the effect of improving the silver removing property increases with an in crease in the amount (y) of N-vinylpyrrolidone, whereas the development suppressing property decreases with the decrease of (y).
- acopolymer having an x/y ratio of /5 to 20/80, in particular 90/10 to 40/60, is preferably used.
- the effect of the copolymer-of the present invention is substantially independent from the degree of polymerization of the copolymer. Therefore, any copolymer capable of being dissolved or dispersed in colloidal state in water or aqueous alkaline solution can be used independently of its degree of polymerization.
- the copolymer of the present invention represented by the formula (I), is obtained by polymerizing, in a solvent, vinylpyrrolidone and a monomer represented by the formula:
- a suitable solvent is water or dimethylformamide.
- Potassium persulfate, hydrogen peroxide or azobisisobutyronitrile may be used as a polymerization initiator.
- isopropanol may be used so as to control the degree of polymerization.
- Synthesis of a monomer represented by formula (II) may be carried out by the reaction of (l) 2-(N-acyl)aminoethyl alcohol with acrylic acid or methacrylic acid, (2) the alcohol with acrylic chloride or methacrylic chloride, (3) the alcohol with ,B-propiolactone or (4) the alcohol with acrylic acid ester or methacrylic acid ester.
- Synthetic Example 1 a Synthesis of 2-(N-formyl-N-methyl)aminoethyl acrylate 52 g of 2-(N-formyl-N-methyl)aminoethyl alcohol was charged into a flask of 500 ml equipped with a stirrer with g of triethylamine, 200 ml of acetone and 1.5 g of hydroquinone as a polymerization inhibitor and, while keeping the temperature at 5 C. and stirring, 46 g of acrylic chloride was dropwise added. After the reaction, the salt was removed and l g of hydroquinone was added followed by distillation. The compound obtained had the following structure which was identified by elementary analysis, NMR, mass spectrometry and infrared spectrum.
- the quantity to be added of the copolymer used in the present invention depends on its properties, the variety of layers into which it is added and, the variety and quantity of the coupler and other additives.
- good results can generally be obtained by employing about 5 percent by weight of the copolymer based on the weight of the binder. Ordinarily, 1-5 percent by weight is preferred since the color-forming efficiency and physical properties of the layer decrease when the addition quantity exceeds 20 percent by weight.
- the copolymer of the present invention may be added to a dispersion during the dispersing of the coupler or it may be added with other additives during the preparation of a coating solution.
- a suitable protective colloid may be used, for example, gelatin, polyvinyl alcohol or its derivative, polyacrylamide or its derivative, cellulose derivative, casein or alginate. Gelatin is most suitable.
- Color development solution sodium hexametaphosphate 2 g. sodium sult'tte (anhydrous) 4 gv Z-methyl-4-N, N-diethylaniline sulfate 3 g. sodium carbonate (monohydrate) 20 g. potassium bromide 2 g. water to make I liter Fixing solution sodium thiosulfate (anhydrous) 153 g. sodium sulfite (anhydrous) l5 g. acetic acid 48 g. boric acid 7.5 g. potassium alum l5 g. water to make 1 liter Bleaching solution potassium bromide 20 g. potassium bichromate 5 g. potassium alum 40 g.
- EXAMPLE 2 The same procedure as in Example l was repeated except that 4.3 g of l-(2,4,6-trichlorophenyl)-3-(3-(N-butyltetradecaneamide)-propaneamide) pyrazoline-S-on was used as a magenta coupler in place of the yellow coupler of Example l and a copolymer of 2-(N-formyl-N-methyl)-aminoethyl methacrylate and N-vinylpyrrolidone (monomer ratio: 6 4) was used as the copolymer.
- a color image of magenta was present together with a cloud of silver and was considerably obscure.
- the optical density of the two films was measured by a red light substantially free from absorption of the color image of magenta.
- the film containing no copolymer gives a high optical density due to the absorption of silver.
- Example 2 The same procedure as in Example 1 was repeated except that 2.4 g of l-hydroxy-4-chlor -2-N-dodecylnaphthamide was used as a cyan coupler in place of the yellow coupler of Example 1 and a copolymer of 2-(N-formyl-N- methyl)aminoethyl acrylate and N-vinylpyrrolidone(monomer ratio: 6 4) was used as the copolymer.
- a color image of cyan was present together with a cloud of silver and was considerably obscure.
- the optical density of the two films was measured by a blue light substantially free from absorption of the color image of cyan. As is evident from the results shown in Table 3, the film containing no copolymer gives a high optical density due to the absorption of silver.
- R represents hydrogen or methyl
- R represents hydrogen, methyl, ethyl, propyl or butyl
- R represents hydrogen, methyl, ethyl, propyl or butyl
- x/y varies from /5 to 20/80.
- the color photographic light-sensitive material as A rolidone of a monomer ratio of 6 4.
- copolymer is a copolymer of 2-(N-forrnyl-N-methyl)aminoethyl methacrylate and N-vinylpyrrolidone of a monomer ratio of 6 4.
- copolymer is a copolymer of 2-(N-acetyl)amino-ethyl acrylate and N-vinylpyrrolidone of a monomer ration of 8 2.
