Description
This application is a continuation of application Ser. No. 08/124,314, filed Sep. 20, 1993, now abandoned.
The present invention relates to a light-sensitive silver halide photographic material for photo-printing. To be more specific. The present invention relates to a color light-sensitive silver halide photographic material which is excellent in gradation and of which is capable of improving the productivity of printing process.
Recently in the field of photographic print, for the purpose of shortening delivery date and improving productivity of printing process, a method of shortening printing time has employed by using silver halide photographic material with high silver chloride content and rapid development. However, since development speed of silver chloride is remarkably fast, it is found that it is difficult to maintain continuous gradation from highlight to shadow portions of the characteristic curve, and that the curve tends to irregularly bend depending upon the processing condition.
Against this disadvantage, a method, whereby it is possible to obtain a characteristic curve with an expanded straight portion from highlight to shadow, by using a silver halide emulsion in which two or more kinds of silver halide grains with different sensitivities are mixed at a suitable ratio, has been proposed and the effect thereof has been recognised.
However, it has been found out when the method for improving gradation characteristics by mixing these emulsions, is applied, especially to a silver halide emulsion sensitized in the blue-light, variation in the gradation at the time of exposure is often seen against the change of the temperature, and thus improvement in the expansion of gradation, which is a main object of the present invention, cannot be achieved.
In view of the state of the art, the appearance of a light-sensitive silver halide photographic material for print which is applicable to rapid process and has improved gradation has long been waited.
The object of the present invention is to provide a light-sensitive silver halide photographic material which is excellent in gradation and stable against external environmental changes such as variations of temperature at the time of exposure.
The silver halide light-sensitive material of the invention comprises a support having thereon a blue-sensitive silver halide emulsion layer, comprising a mixture of at least two kinds of silver halide emulsions each optically sensitized with a blue-sensitizing dye, wherein
(1) the silver halide emulsions each comprise silver chloride grains or silver chlorobromide grains having a silver chloride content not less than 90 mol %,
(2) the silver halide emulsions each have an average grain size, in terms of diameter of spherical grain being within the range of 0.6 μm to 0.9 μm and being different from each other by 0.05 μm or more in the average grain size, and
(3) the coating amount of the blue-sensitizing dye is not more than 7.0×10-4 g/m2.
Silver halide emulsion grain advantageously used in the present invention is one having a silver chloride content of 95-99.95 in terms of mol %. And, more preferably, it is a silver chlorobromide grain which substantially contains no silver iodide. For the purpose of shortening developing time and lowering replenishing amount of the color developer, more preferable silver chloride content is 99.5-99.9 mol %.
As for the crystal shape of the silver halide grain used for the photographic material of the present invention, an arbitary one may be used. According to one preferable embodiment of the present invention, cubic crystals having <100> faces can be mentioned. Moreover, silver halide grains having an octahedral, tetradecahedral or dodecahedral crystal shape, which may be prepared according to the method disclosed, for example, in U.S. Pat. Nos. 4,183,756 and 4,225,666, japanese Patent O.P.I Publications No. 55-26589 (1980), Japanese Patent Publication No. 55-42737 (1980), Journal of Photographic Sciences Vols. No. 21 and 39(1973), etc. may also be used. Farther, grains which have twin plane can also may be used.
Silver halide grains used for the light-sensitive photographic material of the present invention may comprise of a single shape or a mixture of two or more grains of different shapes.
The grain size of the silver halide grains used for the light-sensitive photographic material of the present invention falls within the range between 0.6 and 0.9 microns in terms of diameter when the grain size is converted into an equivalent projection circle.
In the photographic material of the present invention, in order to realize excellent gradation characteristics, it is preferable that the silver halide emulsion is a mixture of two kinds of silver halide emulsions of which average grain size falls within the range between 0.6 and 0.9 μm and the grain size difference between the respective emulsions is more than 0.05 μm. A preferable grain size difference is between a range of 0.07 and 0.15 μm. As a preferable example, a mixture of two kinds of emulsions, of which average grain sizes are 0.7 μm and 0.8 μm, respectively, at a ratio of 65:35 may be mentioned.
The above-mentioned grain size can be measured by various methods used in the photographic field. As typical methods, those described in "Analytical Method for Particle Diameter Measurement" written by Loveland, Symposium on Light Microscopy, A.S.T.M., pp. 94-122(1955) and in "The Theory of Photographic Process, Vol.3" (Mees and James, and published by Mcmillan, 1966) can be mentioned.
When the grains consist substantially of a uniform shape, particle size distribution can be represented considerably accurately as a diameter or an equivalent projection area.
The grain size distribution of the silver halide grains used for the light-sensitive photographic material of the present invention may be either poly-dispersion or mono-dispersion. Preferably, mono-disperse silver halide grains of which variation coefficient of size distribution is not more than 0.22 and, more preferably, not more than 0.15 may be advantageous. Herein, the variation coefficient of grain size distribution is a factor representing the width of particle size distribution and is defined by the following equation.
Variation Coefficient=S/R
In the above, R is standard deviation of particle size distribution and S is the average grain size. The grain size denotes the diameter in the case of spherical silver halide grain and, in the case of the grains of other shape than spherical like cubic grain, it stands for the diameter when the projection image thereof is converted into a circle having equivalent area.
As for preparation of the silver halide emulsion used in the present invention, various methods and equipments which are well known in the art may be employed.
The silver halide emulsion used in the present invention can be the one prepared by either an acid process, a neutral process or an ammonical process. The silver halide grains in the emulsion may be the ones having been grown up either at a time or after forming seed grains. As for the method of making the seed grains and the method for growing the same, it may be either the same or different.
As for the manner of reacting the water-soluble silver salt with the water-soluble halide, either normal precipitaion method, reverse precipitation method, double-jet method, or any combination thereof may optionally be employed, the double-jet mixing method is preferable. Furthermore, as one form of the double-jet method, a method so-called "pAg-controlled double-jet process" described in Japanese Patent O.P.I. Publication No. 54-48521(1979) may also be employed.
Furthermore, an equipment provided with an additional solution-supplying equipment arranged in the mother reaction solution, from which the water-soluble silver salt and the water-soluble halide salt are supplied, which is described in Japanese Patent O.P.I.

An equipment as described in the German OLS Patent Publication No. 2921164, in which the water-soluble silver salt solution and the water-soluble halide salt solution are added, while continuously changing the concentration of the salts and an equipment. Further an equipment may also be used in which the silver halide grains are formed while keeping the distance between the silver halide grains constant and taking out the reaction mother solution from the reaction vessel and condensing it by ultrafiltration method, which is described in Japanese Patent Publication No. 56-501776(1981).
Moreover, if necessary, a silver halide solvent such as the thioether can be used. Further, a compound having a mercapt group, a nitrogen-containing heterocyclic compound or a compound like a optical sensitizer may be added at the time or after completion of the formation of silver halide grains.
For the purpose of reduction sensitizing the silver halide emulsion used in the present invention, various conventional methods can be applied. For instance, a method of adding various reducing agents, a ripening method under condition of high silver ion concentration or high pH can be used.

Other than the above, those sulfur sensitizers described in U.S. Pat. Nos. 1,574,944; 2,410,689 and 2,278,974 can also be used. The adding amount of the sulfur sensitizing agent changes over the range considerably depending upon pH, temperature, and various other conditions such as the size of silver halide grains, etc. As the general standard, a range from about 10-3 mols to 10-7 mols per mol of silver halide mol is preferable. More preferably, it is in the range between 10-6 and 10-5 mols.
It is preferable that the silver halide emulsion used in the present invention is undergone the gold sensitization. As the gold sensitizer, various gold complexes such as chloroaurate, auric sulfide and auric thiosulfate may be used as a ligand compound used, for example, dimethyl rhodanin, thiocyanate, mercapto tetrazole, mercapto triazole can be mentioned.

The amount of the blue-sensitizing dye is important for achieving the object of the present invention. It is found that when the amount exceeds 7.0×10-4 g/m2 in the lightsensitive material constituted, the gradation variation depending on the variation in temperature was remarkable in the light-sensitive material with a blue-sensitive emulsion layer comprising the mixture emulsion of two kinds or more.

Publication No. 4-114154(1992) can be mentioned. To be more specific, Exemplified compounds CC-1 through CC-9 disclosed on pages 18 through 21 in the same may be mentioned.
In the light-sensitive material of the present invention, various dyes having absorption in various wavelength resions can be used for the purposes of anti-irradiation and anti-halation. Any well-known compounds can be used fo this purpose. Especially, as a dye which has absorption in the visible spectral region, dyes AI-1 through AI-11 disclosed on pages 117 and 118 in Japanese Patent O.P.I. Publication No. 3-251840(1991) are preferable.

When a dye-forming coupler used for the silver halide light-sensitive photographic material of the present invention is added to photographic emulsion by oil protect emulsification process, after dissolving a dye-forming coupler in a warer-immiscible high boiling point organic solvent and, if necessary, together with a low boiling point organic solvent and an water-soluble organic solvent, the mixture is emulsion-dispersed in a hydrophilic binder such as gelatin using a surface active agent to form an oil in water type dispersion. As dispersing means, a stirring machine, a homogenizer, a colloid mill, a flow jet mixer, and a ultrasonic homogenizer can be used. A step of eliminating the low boiling point organic solvent may be put during or after emulsification process. As high boiling point organic solvent which can be used to dissolve coupler and to disperse the dye-forming coupler, phthalic acid esters such as di-octyl phosphate and phosphates such as tri-cresyl phosphate can be mentioned. Among these, phthalic acid ester can exert the effect of the present invention more effectively. Moreover, in stead of the method of using the high boiling point organic solvent, a method in which a coupler and a certain polymeric compound, which is immiscible with water and soluble in the organic solvent, are dissolved, if necessary, in a low boiling point organic solvent and/or in a water-soluble organic solvent and then the mixture is emulsified by various dispersion means and using a surfactant in a hydrophilic binder such as aqueous gelatin solution, may also be employed.

*Characteristic curve has a plateau at an intermediate density region.
The following have been understood from the result in Table 1.
Samples 1-5 using the emulsion having the average grain size smaller than the claimed value, 0.6 μm, in the blue sensitive layer is too lower in both of the sensitivity and the gradation. Besides, Samples 30-33, in the blue-sensitive layer of which an emulsion having an average grain size larger than the upper limit of the claimed grain size, 0.9 μm, is used, are high in the sensitivity but undesirably too lower in the gradation because of lower developability thereof.
The samples in which the difference of the average grain size between two emulsions used in the blue-sensitive emulsion layer is 0.05 μm or less, Sample Nos.17 to 21, are not suitable for the light-sensitive material for printing because the contrast is too high and the latitude is too narrow.
Moreover, in the samples with the coating amount of the sensitizing dye falling without of the range of the invention, the gradation is remarkably varied depending on the temperature at the time of exposure and insufficient in the stability in the gradation even though the sensitivity and gradation are sufficient under the ordinary condition.
On the other hand, the color light-sensitive material which was excellent in sensitivity and gradation and had gradation stability extremely excellent furthermore for the variation in temperature found out the sample within the range in the combination of grain sizes in the present invention as for the coated amount of the sensitizing dye.
Experiments were carried out in the same manner as in Example 1 except that the kind of the sensitizing dye and the kind of the stabilizing agent in chemical ripening were changed like showing Table 2. The coated amount of the stabilizing agent was adjusted to the same to STAB-1 used by example 1 amount. The result was shown in the table.

It is found out from the results of Tables 7 and 8 that the sensitivity, the gradation and the stability of gradation to the variation of the temperature at the time of exposure of the samples are sufficient when the mixed emulsion satisfying the requirements of the invention as to the average grain size is used in the blue-sensitive emulsion layer. Such effects have been established also in Example 1.
Moreover, it is found that the gradation variation depending on the temperature at the time of exposing is considerably lowered in Sample Nos. 50, 51, 56, 57, 59 and 60 in which stabilizers of Formula 3 were used together with the sensitizing dye. These samples also have sufficient sensitivity and gradation.
Experiments shown in Examples 1 and 2 were repeated except that yellow coupler YC-8 or Y-12 were used in place of the yellow coupler used in Examples 1 and 2.
As the results of the experiments, the same effects as in Examples 1 and 2 were reproduced. Moreover, it was found that the samples were excellent because of the yellow couplers have sharp spectral adsorption and superior in the color reproduction.
