Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color image forming method for obtaining a print from a print document by a color development process following a printing process, and can obtain a print having particularly excellent color reproducibility quickly and at low cost. The present invention relates to a color image forming method.

(Prior art) The demand for color photographs obtained from silver halide color light-sensitive materials is growing more and more.
It is required that color photos can be obtained quickly and inexpensively if they go to an E-store. There is also a strong demand for stabilizing the finish quality of color prints, reducing the failure rate, and improving the image quality of color images, especially color reproducibility.

In recent years, there have been remarkable advances in techniques relating to silver halide emulsions used in color photographic materials, coloring materials used, and color development processing. However, a technique for properly printing a color print photosensitive material through a print original made of a photographed color photosensitive material, that is, a blue-sensitive layer, a green-sensitive layer, or a red-sensitive layer of the color print photosensitive material according to the print original. A technique for independently and balancedly exposing the blue light component, the green light component, or the red light component to exposure can be said to be a key to improving the finish quality.

Conventionally, a method using a color filter for a printer has been proposed in US Pat. No. 2,997,389 (French Patent No. 1248376 and Japanese Patent Application Laid-Open No. 51-113627) to stabilize the finished quality. In particular, a method using an optical filter to improve the spectral sensitivity of a printer sensor that detects the color of a printed document and the separation of blue, green, and red light components for exposure to facilitate application is disclosed in Japanese Patent Laid-Open Showa 53-64037
No. has been proposed. Further, a method of providing a dye-containing filter layer is disclosed in British Patent No. 1,015,683 and French Patent No. 1,248,3.
No. 76, Japanese Patent Publication No. 51-1419, and Japanese Patent Application Laid-Open No. 60-45237.

However, the color mixing between the photosensitive layers of the photographic color light-sensitive material used to make a print original, the spectral transmission characteristics of the color-developed image, the spectral sensitivity distribution of the color print-sensitive material, and the spectral absorption characteristics of the color-developed image, and thus color development There are stains during the processing, residual color of the dye, and inter-layer color mixing during the color development, and the practical use of the color separation filter is not clear. On the other hand, since the spectral transmission characteristics of the filter are not appropriate, the printing time is prolonged, and it is often difficult to adjust each exposure component for achieving color balance.

(Problems to be Solved) A first object of the present invention is to provide a method for printing a color print photosensitive material through a print original without prolonging the printing time so as to obtain a print having excellent finish quality, especially color reproduction. To provide. Secondly, the color mixing between layers occurring during the color development process of the color photographic material or the color print photographic material for photography and the dye image forming material used in the color print photographic material are improved, and this effect is synergistically improved to improve the image quality. It is an object of the present invention to provide an image forming method which improves the bonding method. Other objects will be apparent from the description of the invention.

(Means for Solving the Problems) The present inventors have achieved the object of the present invention as follows.

(1) In a color image forming method for obtaining a color print by performing a color development process following a step of printing a color print original on a color print photosensitive material, a light source used in the printing step and the color print photosensitive material A band stop filter having the following characteristic A is used between the photosensitive layer and the photosensitive layer of the color print photosensitive material. Further, the intermediate layer located between the photosensitive layers or the photosensitive layer of the color print photosensitive material has the following general formula (I): A color image forming method comprising a compound represented by the formula:

(2) In a color image forming method for obtaining a color print by performing a color development process subsequent to a step of printing a color print photosensitive material through a color print original obtained from a photographed color photosensitive material, and using the above print step. A band stop filter having the following characteristic A is used between the light source to be used and the photosensitive layer of the color print photosensitive material, and further, an intermediate layer located between the photosensitive layer of the photographing color photosensitive material or both photosensitive layers. And a compound represented by the following general formula (I).

Characteristic A: At least one photosensitive layer in the color print photosensitive material has a half width of a spectral transmittance curve of a band stop filter in a wavelength region excluding a range of a maximum spectral sensitivity wavelength (λ ^max ) ± 20 nm.

Formula (I) (where Cp is a coupler residue which couples with an oxidized form of a color developing agent to form a substantially colorless compound (including a case where the compound becomes colorless by reacting with a developing solution component) X represents a coupler residue which forms a compound which can be coupled out during the development process of the coupler to be eluted or diffused out of the layer in the light-sensitive material, and X is located at the coupling position of the coupler and represents an oxidized form of the color developing agent. Represents a group capable of reacting with, or a group capable of reacting and leaving.

 Next, the features of the present invention will be described.

A first feature of the present invention is that the maximum spectral sensitivity wavelength (λ) of each photosensitive layer of the color print photosensitive material during the printing process is preferably used.
^max ) A band-stop filter having a half-width (W1 _{/ 2} ) of a spectral transmittance curve of the filter in a wavelength region excluding ± 20 nm, preferably λ ^max ± 20 nm. The W _1/2 of the band stop filter used in the present invention is preferably 5 to 60 nm, more preferably 10 to 40 nm. On the other hand, if the spectral transmittance curve is too broad, the sensitivity of the printed photosensitive material becomes substantially low, and a defect that the printing time is prolonged is produced, thereby reducing the effect of improving color reproducibility. 1/4 value width (W) to 3/4 value width ((W _3/4 )) of the spectral transmittance curve of the band stop filter according to the present invention.
Ratio _{1/4) (W 1/4 / W 3/4} ) is dependent on the position of the W _1/2 value and lambda ^max, preferably 0.35 or more, still good properly 0.5
~ 1.0. Incidentally, a band stop filter having this ratio of 0.5 or more is virtually non-existent.

The band stop filter according to the present invention comprises an infrared absorbing filter, a color correction filter or a gray filter between the light source of the printer and the setting position of the color printing photosensitive material, preferably between the light source and the print original. filter).
A method of incorporating these filters into a printer is described in, for example, Japanese Patent Application No. 62-146544.

The band stop filter used in the present invention is a filter in which dielectrics having different refractive indices are provided as a multilayer thin film on a substrate, and reflects light in a specific wavelength range and transmits light in other wavelength ranges.

As the substrate used for the substrate, glass, silicon, sapphire, crystal, surface-treated plastic film or plate is usually used. Dielectrics can be found in Tables 2.6 on page 817, section 2.2, especially page 820, in "Thin Film Handbook" (Ohmsha, published in 1983) edited by the 131st Committee of Thin Films, Japan Society for the Promotion of Science.
Is shown in As an inorganic compound, for example, silicon dioxide, silicon oxide, aluminum oxide, tin oxide, zirconium oxide, titanium dioxide, zinc sulfide, silicon, germanium compound, tellurium compound, and silver as a metal,
Aluminum, neodymium, titanium, thallium, etc. If necessary, select organic dielectrics such as those described in Section 1.2 on page 523, especially polymer dielectrics, such as polystyrene, polypropylene, polyimide, FEP Teflon, pol γ-benzyl glutamate, etc. Can be used.

At least two or more kinds of dielectric materials having different refractive indices can be repeatedly formed by setting the film thickness to provide multiple layers (preferably 5 to 50 layers, and more layers if necessary). The design guideline is described in, for example, the aforementioned “Thin Layer Handbook”, page 823 [4], and in Chapter 6 of “Optical Thin Film”, 2nd Edition (1986, published by Kyoritsu Shuppan Co., Ltd.) edited by Shiro Fujiwara. I have. The multilayer thin film can be provided by a sputtering method, a CVD method, a coating method, or the like, but is preferably provided by a vacuum evaporation method.
Also, a plurality of filters can be attached to each other.

More specifically, it can be manufactured by narrowing the absorption band width according to the band step filter BSF manufactured by Koshin Kogaku Kogyo KK.

The minimum transmittance of the preferred band-stop filter used in the present invention is preferably less than 30%, more preferably less than 20%, more preferably less than 10%.

The band stop filter according to the present invention can be said to be a kind of interference filter described in, for example, Chapter 21 of the Color Science Handbook, edited by the Japan Society of Color Science, Chapter 21, 1985, Tokyo University Press. However, band stop filters having such a low shear and low transmittance have not been realized in practice.

In the band stop filter used in the present invention, the wavelength range occupied by W1 _{/ 2} of the spectral transmittance curve is preferably 480.
540 nm and / or 570-630 nm, and it is preferable to use this filter in combination with an ultraviolet absorption filter having an absorption at a wavelength shorter than 420 nm or an infrared absorption filter having an absorption at a longer wavelength than 750 nm.

By using the band-stop filter according to the present invention, the color mixture of each component of the yellow, magenta and cyan color images can be greatly improved. For example, Japanese Patent Application No. 62-150320
The average color mixture when using Macbeth's color chart as the subject is 0.10 or less as described in the issue, and 0.07 when applied to a normal color negative color paper system.
It can be reduced below. In short, by cutting unnecessary absorption of a color image constituting a print original, it is possible to reduce color mixture that causes the spectral sensitivity of the print photosensitive material as noise. For example, Japanese Patent Application No. 62-15
As described in JP-B-8643, the spectral absorption characteristics of the yellow, magenta and cyan images constituting the print original and the spectral sensitivity characteristics of the blue-sensitive layer, green-sensitive layer and red-sensitive layer of the color print photosensitive material It is possible to improve the color mixture of the color image components, the decrease in the saturation of the color image, and the fluctuation of the finished quality due to poor compatibility with the image quality.

A second feature of the present invention is to improve color mixing between layers which occurs when a color photographic material or a color print photographic material is subjected to color development processing. With this improvement, the effect of the first feature was unexpectedly and more clearly recognized unexpectedly.

Conventionally, as a color mixing inhibitor, hydroquinone derivatives,
Aminophenol derivatives, amines, gallic acid derivatives,
Catechol derivatives, ascorbic acid derivatives, sulfonamidophenol derivatives and the like are known. However, compounds which have been conventionally useful as color mixture inhibitors have strong reducibility, and thus have the disadvantageous side effect of fogging photosensitive silver halide during color development and suppressing color-forming reactions.

In the present invention, in addition to the effect that the compound represented by the general formula (I) has few side effects as described above, the effect of using the band-stop filter according to the present invention becomes more and more remarkable. Was found to be expressed.

Next, the compound represented by formula (I) will be described in detail.

The compound formed immediately after the coupler represented by the general formula (I) is subjected to the coupling reaction with the oxidized form of the developing agent has two types, that is, a colored compound or a substantially colorless compound. In the former case, the dye is not used for image formation in the present invention. That is, the dye formed at the time of development becomes alkali-soluble and diffuses from the photographic layer, or when flowing out into the developer, or reacts with a component contained in the developer, for example, a sulfite ion or a hydroxyl ion. A preferred example is when the color becomes substantially colorless.
They may occur at the same time, but in any case, a colored compound formed during development by coupling of the coupler represented by the general formula (I) with the oxidized developer remains in the photographic layer after the development processing. The amount to be performed is preferably 10% or less,
More preferably, it is at most 5%.

In the above, when the dye becomes alkali-soluble,
This is when the dye has a hydrophilic group, preferably a dissociating group. The degree of alkali solubility greatly varies depending on the environment during the development processing, for example, depending on the pH of the processing solution, the processing time, and the structure of the developing agent. However, Cp of the general formula (I)
Can be adjusted to a desired degree by selecting the substituent contained in the above.

In the above description, the case where the dye reacts with the components contained in the developer to become substantially colorless includes, for example, "The Journal of the Photographic Society of Japan", Vol. 27, p. 172 (1964) and "Journal.
Of the American Chemical Society "(J. Am
er. Chem. Soc.) 84: 2050 (1962). The rate of the colorless reaction depends on the type and amount of the components contained in the developer, but can be adjusted to a desired extent by selecting the structure of the group represented by Cp and the selection of the substituent.

As the group represented by Cp, an ordinary coupler residue can be applied. That is, a yellow coupler residue (for example, open-chain ketomethylene type coupler residue), a magenta coupler residue (for example, 5-pyrazolone type or pyrazolotriazole type coupler residue), a cyan coupler residue (for example, phenol type or naphthol type coupler residue) ) And non-colored coupler residues (e.g., coupler residues of indanone type, acetophenone type, etc.);
315,070, 4,183,752, 3,961,959 or
It may be a heterocyclic coupler residue described in 4,171,223.

The compound represented by formula (I) preferably has a diffusion-resistant group. The diffusion-resistant group is a group for preventing the compound of the formula (I) from migrating from the layer to which the compound is added and diffusing into another layer. Usually, an organic substituent for increasing the molecular weight is used.

In the general formula (I), when the group represented by Cp is a yellow coupler residue, a magenta coupler residue or a cyan coupler residue, the case where the diffusion-resistant group is included in the group represented by X is a preferable example. Here, X may be one containing at least one group represented by Cp, for example, one that forms a bis-type, telomer-type or polymer-type coupler.

When the group represented by Cp in the general formula (I) is a colorless coupler residue, the non-diffusible group may be included in any of the groups represented by Cp or X. Here, Cp may contain two or more non-color coupler residues, or X may form a bis-type, telomer-type or polymer-type coupler containing one or more Cp.

The group represented by X in the general formula (I) represents a coupling-off group, which may be either a group that reacts with the oxidized developing agent or a group that does not react after leaving.
When X represents a group that reacts with an oxidized developing agent, X is Cp
It is a group that becomes a coupler when further cleaved or a group that becomes an oxidation-reduction group after being cleaved from Cp.

When X is a coupler, for example, in the case of a phenol type coupler, it is a group bonded to Cp at an oxygen atom excluding a hydrogen atom of a hydroxyl group. In the case of a 5-pyrazolone-type coupler, it is bonded to Cp at an oxygen atom obtained by removing a hydrogen atom from a hydroxyl group compatible with 5-hydroxypyrazole. In these examples, X is a phenol-type coupler or a 5-pyrazolone-type coupler only after X is separated from Cp. It is a preferred example to have a coupling-off group containing a diffusion-resistant group at the coupling position.

On the other hand, when the group represented by X in the general formula (I) represents a redox group, X is preferably a hydroquinone, a catechol, a pyrogallol, a 1,4-hydroxynaphthol or a 1,2-hydroxynaphthol. It is.

It is a preferable example that these reducing agents have a diffusion-resistant group. The group which does not react with the oxidized developing agent after leaving is an ordinary coupling-off group, such as a halogen atom.

The crystal structure may be uniform, the inside and the outside may be composed of different halogen compositions, or may have a layered structure.Also, silver halides having different compositions are joined by epitaxial bonding. And it may be bonded to a compound other than silver halide such as, for example, silver rhodan or lead oxide.

 Also, a mixture of particles of various crystal forms may be used.

As the silver halide emulsion, usually, those subjected to physical ripening, chemical ripening and spectral sensitization are used. The additives used in such a process are Research Disclosure N
o.17643 and No.18716 (see later chapter).

The color print light-sensitive material used in the present invention is a color photographic paper, a direct positive color light-sensitive material, a reversal color light-sensitive material, and the like. In particular, the spectral sensitivity distribution of each light-sensitive layer provided on a support is a color reproduction according to the present invention. It greatly affects the stability and finish quality.

The silver halide emulsion used in the color print light-sensitive material of the present invention, in particular, GL or RL, preferably does not have strong intrinsic sensitivity in the BL wavelength region and a longer wavelength region.

Silver halide photosensitive emulsions are usually practically used for silver iodobromide emulsions at wavelengths shorter than about 540 nm, for silver bromide at wavelengths shorter than about 500 nm, and for silver chloride at wavelengths shorter than about 420 nm. It gives a latent image by absorbing light, that is, it has photosensitivity. For example, TH Themes of the Photographic proc
It is shown, for example, on pages 39 to 44 of ess (1977, 4th edition). Therefore, the halogen composition of the silver halide grains and the method of crystal formation are important for the present invention.

The silver halide emulsion used in the present invention, particularly for color printing, is described in Japanese Patent Application Nos. 62-39825 and 62-8.
Nos. 6163, 62-86164 and 62-86165, silver chloride and silver bromide mainly surrounded by the (100) plane as described in JP-A-62-86165.
Alternatively, a silver chlorobromide emulsion containing substantially no silver iodide and comprising a mixed crystal thereof is preferred. As described in Japanese Patent Application Laid-Open No. 62-47225 and Japanese Patent Application No. 62-150320, (11)
1) A silver chlorobromide emulsion substantially free of silver iodide and composed of silver chloride, silver bromide or a mixed crystal thereof having a surface is preferred.

Substantially free of silver iodide means that the content of silver iodide is 2 mol% or less, preferably 1 mol% or less, based on the total silver halide amount. More preferably 0.
It is at most 5 mol%, and most preferably contains no silver iodide. Including silver iodide has many useful points such as increasing light absorption in terms of photosensitivity, enhancing adsorption of spectral sensitizing dyes, or weakening desensitization by spectral sensitizing dyes. When a short-time rapid phenomenon is performed in a system using the technology of the present invention, a low development speed results in a slow development speed of the entire silver halide grains, and the average color mixing degree of the present invention is also improved. Brings a great disadvantage. In some cases, it is advantageous to contain 0.4 mol% or less of silver iodide for the adsorption of a separation sensitizing dye, but in the present invention, a silver halide emulsion essentially free of silver iodide is used. Is preferred.

The effect of the band stop filter according to the present invention can be exerted by using various silver bromide, silver chlorobromide and silver chloride.
However, in order to improve the color reproducibility according to the present invention, the silver chlorobromide having a silver bromide content of 30 mol% or less or the silver bromide content having a silver iodide content of 0.4 mol% or less in the color print photographic material is required. Silver bromochloride or silver chloride emulsions of 10 mol% or less are preferred.

The halogen composition of the silver halide emulsion used in the present invention,
Further, it is related to the residual color and desilvering property of the dye in the color development processing, and it is disadvantageous particularly when the content of silver iodide is large. The characteristics related to the halogen composition are not determined only by the halogen composition of the whole grain, but also by the kind of halogen distribution in the grain. Therefore, in the present invention, the silver halide emulsion can have a distribution or a structure with respect to the halogen composition in the grains.
A typical one is a multi-structure type particle having a halogen composition in which the inside of the particle and the whole or part of the surface layer have different halogen compositions. In such particles, for example, the shape of the core and the overall shape with shells may be the same or different. Specifically, the core part may be cubic and the shape of a shell-attached particle or cube, or the core may be octahedral and the shell-attached particle may be cubic. is there. In addition, although the core portion is a clear regular particle, the shape of the shelled particle may be slightly collapsed. Instead of a simple double structure, a triple structure or a multi-layer structure of a triple structure or more can be used, and silver halide having a different composition can be thinly applied to the surface of a core shell double structure grain.

In order to provide a structure inside the particle, not only the above-described wrapping structure but also a particle having a so-called bonding structure can be produced. The fine crystal to be bonded can be formed by bonding to the edge, corner, or face of the host crystal with a composition different from that of the host crystal. Such a junction crystal can be formed regardless of whether the host crystal has a uniform halogen composition or has a structure such as a core shell type. The host particles having these structures may have, for example, a core-shell type particle having a high silver bromide content in the core portion and a low silver bromide content in the shell portion, or vice versa. Similarly, the grain itself having the bonding structure may be a grain having a high silver bromide content of the host crystal and a relatively low silver bromide content of the bonding crystal, or may be the reverse grain. .

In addition, the boundary portion having a different halogen composition of the grains having these structures may be a clear boundary, or may be an unclear boundary by forming a mixed crystal due to a composition difference. It may have a structural change.

In the present invention, an emulsion composed of the above-mentioned core shell grains or bonded grains having any structure with respect to the halogen composition rather than having a uniform composition within the grains is preferably used.

Japanese Patent Application Nos. 62-86163, 62-86164, 62-86165 and 62-150320 describe silver halide grains and sensitizing dyes whose development starting point is controlled as described in the specification. Emulsions containing silver halide grains with suppressed halogen conversion are preferably used.

The average size (average of the diameter of a sphere equivalent to a volume) of a silver halide emulsion used for a color print photosensitive material is preferably 2 μm or less and 0.1 μm or more. Especially preferred is 1.4μ or less
It is 0.15μ or more.

The narrower the particle size distribution, the better, a monodispersed emulsion is preferred. Particularly, a monodisperse emulsion having a regular shape is preferable in the present invention. ± 20% of average particle size by number or weight of particles
Emulsions within 85 ° C of all grains within, and especially
Emulsions containing 90% or more are preferred.

In particular, the iridium salt or its complex salt is preferably 10 ^-9 to 10 ^-4 mol / mol, more preferably 10 ^-8 to 10 ^-5 , based on silver halide.
Mol / mol is used. This is because, compared to an emulsion prepared without using an iridium salt or a complex salt thereof, in order to obtain rapid developability and stability when performing exposure at high or low illuminance outside the proper exposure illuminance range, Useful.

Known silver halide solvents (e.g., ammonia, potassium thiocyanate, U.S. Pat. No. 3,271,157, JP-A-51-12360, JP-A-53-82408, JP-A-53-144319)

To remove the soluble silver salt from the emulsion after the physical ripening, it is possible to use Nudel washing, flocculation sedimentation method, ultrafiltration method or the like.

The silver halide emulsion used in the present invention can be chemically sensitized by sulfur sensitization, selenium sensitization, reduction sensitization, noble metal sensitization, etc., alone or in combination. That is, a sulfur sensitization method using active gelatin or a compound containing sulfur capable of reacting with silver ions (eg, thiosulfate, thiourea compound, mercapto compound, rhodanine compound, etc.), a reducing substance (eg, stannous salt) , Amine salts, hydrazine derivatives, formamidinesulfinic acid, silane compounds, etc.) and metal compounds (eg, gold complex salts, Pt, I

In order to improve the color reproducibility by making the spectral luminous intensity distribution of the light received by each photosensitive layer independent from each other at the time of printing of a color print photosensitive material, as described in Japanese Patent Application No. 62-206589, it is preferable. More preferably, J-type spectral sensitization is applied to the blue-sensitive layer of the color print photosensitive material, and J-type or M-type spectral sensitization is applied to the green-sensitive layer or the red-sensitive layer.

For such spectral sensitization, a cyanine dye, a merocyanine dye, a complex cyanine dye, a complex merocyanine dye, a holopolar cyanine dye, a hemicyanine dye, a styryl dye, and a hemioxonol dye can be selected and used. .

pm or less) The effect of improving color reproducibility according to the present invention is described in Japanese Patent Application No. 62-1503.
It can be indicated by the degree of color mixture using Macbeth Color Chart described in the specification of No. 20.

The color print photosensitive material of the present invention is a color photographic paper,
A direct positive color light-sensitive material, a reversal color light-sensitive material, etc., but generally a blue-sensitive silver halide light-sensitive layer having a spectral sensitivity substantially in the wavelength range of 390 nm to 485 nm on a support, 48
A green-sensitive silver halide photosensitive layer having a spectral sensitivity in the wavelength range of 0 nm to 600 nm, preferably substantially 485 nm to 570 nm, and a red-sensitive silver halide photosensitive layer having a spectral sensitivity in the wavelength range of 570 nm to 740 nm for practical use. Become. The main role of the color print photosensitive material is to convert the image information of the three primary colors of the color print original into blue, green, and green layers of the color print photosensitive material according to the spectral transmittances of yellow, magenta, and cyan. To be faithfully reproduced independently of each other in response to the spectral sensitivity of the red-sensitive layer.

Generally, in order to evaluate the color reproducibility, a Mac Vestart comprising 18 chromatic colors and 6 achromatic colors can be used.
For example, it is described in CSM MaCamy et al., J. Appl. Phot. Eng. 2, pp. 95-99 (1976).

Generally, among the blue-sensitive layer, the green-sensitive layer, and the red-sensitive layer in the color print photosensitive material, the green-sensitive layer has a defect that the color reproducibility is most deteriorated. Therefore, here, the green layer of the color print photosensitive material will be described in detail. The spectral transmittance distribution of the color negative dye obtained by shooting the color chart i
(Λ), the spectral sensitivity distribution of the green sensitive layer of the color print photosensitive material is S (λ), and the energy distribution of the printing light source is P (λ).
The exposure amount that the green sensitive layer receives is given by the following formula (I) for the color chart i. Given by

Usually, a color print photosensitive material is printed so that a medium-density achromatic color is finished to a predetermined density on a print, and the achromatic color chart (i is 2
2, as the exposure amount E ₂₂ of the optical density of about 0.7) is 1.0, when determining the exposure amount Ei of other Chiyato, is defined by the following formula (2)
Hi indicates that the exposure amount Ei of the color of the chart i is larger or smaller than the reference achromatic color.

Hi = Ei / E ₂₂ (2) The main maximum sensitivity wavelength of the green sensitive layer is set as the ideal spectral sensitivity distribution, and a delta function type spectral sensitivity distribution having a sensitivity of 5 nm at the center is set. Is set to Hi ⁰ . Αi defined by the following equation (3) indicates the magnitude of deviation of the exposure amount of the color of the chart i from the ideal.

αi = Hi / Hi ⁰ (3) Then, the color mixing degree βi of the color of the chart i can be defined as in the following equation (4).

βi = αi−1.0 (4) As shown in the following (5), the color mixing degree β of the color of the chart i
The average of 18 chromatic chart colors of the mathematics of i can be averaged, and this can be defined as the average color mixture degree γ.

The average color mixture of the blue sensitive layer and the red sensitive layer also has an effective wavelength range.
Defined similarly instead of 390nm-485nm and 570nm-740nm,
It can be easily obtained.

Using the samples 101 and 102 and the samples 103 and 109, a Macvestiat was photographed under a standard light source for photographing (about 5,500 ° K). Next, a color negative film was obtained by developing according to the color developing method A described above. The color negative film was baked on color photographic paper samples 201 and 202 by using a printer through a color negative film.
A color development process was performed by adjusting the development time according to the processing method B, and a print was obtained.

With respect to this print, the color mixing degree βi of the above-mentioned MacVestiat color was determined.

 The results obtained are shown in Table 3.

From the values of the color mixing degree βi = 16 in Table 3, the sample 101 for comparison was used.
It can be seen that Samples 103 and 109 according to the present invention are yellow Y (i = 16) and have less color mixture than Samples 102 and 102 when the same color printing paper is used. In addition, as is clear from the values of the degree of color mixture in Table 4, the same can be said for the samples 104, 105, 106, and 107 as for the sample 103.

Next, the band stop filter A having the spectral transmittance distribution shown in FIG. 1 was mounted on a printer (between the light source and the color negative film), and the degree of color mixing (β ^F _i) = 16 was evaluated in the same manner as printing. The bandstop filter had the following characteristics:

Wavelength range occupied by W1 _{/ 2} : 488 to 530 nm W1 / ₄ / W3 / ₄ = 0.76 The results are shown in Tables 3 and 4.

From the above table, the color photographic light-sensitive material of the present invention (sample 10
3 to 107 and 109), it can be seen that the color mixture of magenta is small in yellow, and that the color mixture of magenta is further small when a band stop filter is used. In addition, the results of separately evaluating green Gi = 14 show that using a sample according to the present invention and further using a band stop filter,
It was learned that it was reproduced with a high saturation and bright freshness.

In addition, Fujifilm's FAP-3500 auto printer
The band-stop filters A and B shown in FIGS. 1 and 2 are attached to the type and printed on the samples 201 and 203 of the color print photographic material of Example 1 according to Fujifilm standard color development processing CP-20. A color development process was performed at the same color development time to obtain a print. For these prints, the color reproduction of yellow Yi = 16 and green Gi = 14 was evaluated. In both cases of using the color negative samples 101 and 103, it was found from the naked eye observation that the print using the sample 203 had less magenta color mixing in the yellow and green images than the print using the sample 201.
