Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a novel cyanazo dye image-forming compound and a color photosensitive material containing the same.

(Prior Art) Color diffusion transfer photography using azo dye imaging compounds which, as a result of development under basic conditions, yield azo dyes that develop diffusivity different from that of the imaging compound itself is well known in the art. It is being

For example, as an image forming compound that releases a cyan dye, US, J, 2 Gu, Ri♂ No. 7, [JS.

11.0/J, A33, US, lI, 273.70r
There is one described in No., US, 4T, Za♂, No. 6-3.

However, it has been revealed that the compounds disclosed in these prior documents all have a nitro group at the para position of the azo group, and this has the drawback of being reduced and discolored during development. ′! In addition, since azo dyes having a nitro group generally have photoreducibility, the light fastness of images is not good.

Furthermore, when these image-forming compounds are contained in the same layer as the photosensitive silver halide hole 4J, a phenomenon that inhibits the development of the halogenated parent may be observed, and the cause of this is probably due to the nitro group. It is estimated that

Tokukai Akira! ! No. 662.27 describes a cyanano dye image-forming compound having a trifluoromethanulfonyl group at the para position of the azo group. However, in addition to the synthetic and pollution problems that the compound contains fluorine, further improvements have been desired in terms of the sharpness of the hue and the diffusivity of the released dye. No. 1, No. 1, No. 1, No. 4, and No. No. 5, No. 1999 discloses a magenta azo dye IfI image-forming compound using a diazo component having a plurality of alkylsulfonyl groups. However, in all of these, the 2-position of the naphthol is either unsubstituted or has an electron-withdrawing group introduced, and the hues of all of these are too short wavelengths to be used as cyan dye image-forming compounds.

In other words, no cyan dye image-forming compounds other than those having a dil-o group or a trifluorometa/sulfonyl group at the azo group/position are known.

Recently, a diazo component having no nitro group or trifluoromethane nylphonyl group and -monoacylamino/-
Novel cyanazo image-forming compounds obtained by azocaburi/g with naphthol cautery were disclosed in JP-A-60-23-Hiro J4.

7!It is proposed in the 7th issue. The image-forming compounds described in these documents are Ishikawa's cyan dyes compared to conventional compounds, but they are shallow in hue and do not have sufficient color reproducibility.

Also, since the hue is hypsochromic, an extra amount of image forming compound had to be used to obtain good gray balance.

(Objective of the Invention) The first object of the present invention is to provide a compound that forms images with excellent light fastness. The second object is to provide an image-forming compound that provides a beautiful pigment with a cyan hue. The third object is to provide a color photosensitive material that has excellent light fastness and forms cyan images with excellent hue.

When the color photosensitive material of the present invention is applied to a system that forms images by diffusion transfer of dyes, a light-sensitive element and an image-receiving element or a dye-fixing element are essential. There are two types: a form in which the particles are coated separately on one support, and a form in which they are coated on the same support.

The relationship between the photosensitive element and the dye fixing element, the relationship with the support,
The relationship with the white reflective layer is special! The tr-t page of Turco Otsu♂726 specification and the US patent.

! No. 00,621s! The relationship described in column 7 is also applicable to the present application.

A practical form of a film unit in which a light-sensitive element and an image-receiving element or a dye-fixing element are provided on the same support is:
The image-receiving element' and the photosensitive element are laminated on one transparent support, and there is no need to separate the photosensitive element from the image-receiving element after the transferred image is completed. More specifically, the image-receiving element comprises at least one mordant layer, and in preferred embodiments of the light-sensitive element, a combination of a blue-sensitive emulsion layer, a green-sensitive emulsion layer and a red-sensitive emulsion layer, or a green-sensitive emulsion layer. layer,
A combination of a red-sensitive emulsion layer and an infrared-sensitive emulsion layer, or a combination of a blue-sensitive emulsion layer, a red-sensitive emulsion layer, and an infrared-sensitive emulsion layer, and a yellow dye image-forming compound, magenta in each emulsion layer. A dye image-forming compound and a cyan dye image-forming compound are each comprised in combination (herein "
The infrared light-sensitive emulsion layer has a thickness of 7 mm or more, especially 7 mm.
(refers to an emulsion layer that is sensitive to light with a wavelength of m or more). Each of these photosensitive emulsion layers may be divided into two or more layers if necessary. A white reflective layer containing a solid pigment such as titanium oxide is provided between the mordant layer and the photosensitive layer or the dye image-forming compound-containing layer so that the transferred image can be viewed through the transparent support.

A light-shielding layer may be further provided between the white reflective layer and the photosensitive layer so that the development process can be completed in a bright place. Further, if desired, a peeling layer may be provided at an appropriate position so that all or part of the photosensitive element can be peeled off from the image receiving element.

).

In another form that does not require peeling, the photosensitive element described above is coated on one transparent support, a white reflective layer is coated on it, and an image-receiving layer is further laminated thereon. A US patent discloses an embodiment in which an image receiving element, a white reflective layer, a release layer, and a photosensitive element are laminated on the same support, and the photosensitive element is intentionally peeled off from the image receiving element! , No. 730.71I.

On the other hand, there are two types of conventional forms in which a photosensitive element and an image-receiving element are separately coated on two supports.
One is a peelable type, and the other is a type that does not require peeling. To explain these in detail, a preferred embodiment of the peelable film unit has a light-reflecting layer on the back surface of the support, and at least one image-receiving layer is coated on six surfaces thereof. In addition, the photosensitive element is coated on a support having a light-shielding layer, and the surface coated with the photosensitive layer and the mordant layer do not face each other before the end of exposure, but after the end of exposure (for example, during development) the surface coated with the photosensitive layer does not face each other. It is devised so that it turns around and overlaps the surface on which the image-receiving layer is applied. Immediately after the transfer image is completed with the mordant layer, the photosensitive element is peeled off from the image receiving element.

In a preferred embodiment of the peel-free film unit, at least one mordant layer is coated on a transparent support, and a photosensitive element is coated on a support having a transparent or light-blocking layer, The surface coated with the photosensitive layer and the surface coated with the mordant layer are stacked facing each other.

All of the above-mentioned embodiments can be applied to both the color diffusion transfer method and the thermal development method, but especially in the former case, a container (processing element) that contains the entire alkaline processing solution and is rupturable under pressure is combined. You can leave it there. In particular, in a peel-free film unit in which an image-receiving element and a photosensitive element are laminated on one support, the processing element is preferably disposed between the photosensitive element and a cover sheet overlaid thereon.

Further, in the case where a photosensitive element and an image receiving element are separately coated on two supports, it is preferable that the processing element is placed between the photosensitive element and the image receiving element at the latest during development processing. Depending on the form of the film unit, the processing element preferably contains a light blocking agent (such as carbon black or a pH-dependent dye) and/or a white pigment (such as titanium oxide). Further, in color diffusion transfer film units, a neutralization timing mechanism comprising a combination of a neutralization layer and a neutralization timing layer is preferably incorporated into the cover sheet, the receiver element, or the photosensitive element.

Polymer mordants are preferred as the mordants used in the above-mentioned image-receiving element and the dye-fixing element described below. Here, the polymer mordant includes a polymer containing a tertiary amine group, a polymer having a nitrogen-containing heterocyclic moiety, a polymer containing these μ-class cation groups, and the like.

For specific examples of hardening agents, please see Tokugansho! Turco Jr5'J4 statement clerk's information page 1 and Tokkai Sho! Examples include those described in Tar/j7 Otsu No. 36, page (3?), and these can be used alone or in combination.

Further, in order to promote dye transfer, a hydrophilic thermal solvent that is solid at room temperature and soluble at high temperature may be incorporated into the photosensitive element or dye fixing element. The hydrophilic thermal solvent may be incorporated into either the photosensitive element or the dye fixing element, or may be incorporated into both. The built-in layer may also be an emulsion layer, an intermediate layer, a protective layer, or a dye fixing layer, but the dye fixing layer and/or
Alternatively, it is preferable to incorporate it into a layer adjacent thereto. Examples of hydrophilic heat solvents include ureas, pyridines, amides, sulfonamides, imides, alcohols, oximes, and other heterocycles. Further, in order to promote dye transfer, a high boiling point organic solvent may be contained in the photosensitive element and/or the dye fixing element.

The support used in the photosensitive element and/or dye-fixing element of the present invention is one that can withstand processing temperatures.

Common supports include glass, paper, polymeric films, metals and their analogs, as well as patent applications! Tarsty Octopus No. 6 Specification Nori! The supports described on page 6 can be used.

The photosensitive element and/or the dye fixing element may have a conductive heating layer as a heating means for thermal development or diffusion transfer of the dye.

The transparent or opaque heating element in this case can be made using conventionally known techniques for producing resistive heating elements. As a resistance heating element, there are two methods: a method using a thin film of an inorganic material exhibiting semiconductivity, and a method using a thin film of an organic material in which conductive fine particles are dispersed in a binder. Materials that can be used in these methods are available at Tokugansho! Tah/! /113 specification etc. can be used.

In the present invention, the method of coating the heat-developable photosensitive layer, protective layer, intermediate layer, undercoat layer, ζtack layer, dye fixing layer, and other layers is described in US Pat. 00. The methods described in columns jj to jg of issue A can be applied.

Radiation, including visible light, can be used as a light source for imagewise exposure to record an image on the photosensitive element. In general, the light sources used for normal color printing, such as tungsten lamps, mercury lamps, halogen lamps such as iodine lamps, xenon lamps, laser light sources, CRT light sources, light emitting diodes (LEDs), and special applications such as tungsten lamps, mercury lamps, iodine lamps, etc. No. 6, page 100 and US Patent ≠, No. 100.124! The light sources listed in column 6 can be used.

In the image forming method having a heating step to which the present invention is applied, for example, the heat development and dye transfer steps may be independent of each other or may be simultaneous. Also, −
The process may be continuous in the sense that transfer is performed following development.

For example, (1) after imagewise exposing and heating the photosensitive element,
There are two methods: (2) a method in which the dye-fixing elements are stacked and heated if necessary to transfer the mobile dye to the dye-fixing element; and (2) a photosensitive element is imagewise exposed, and the dye-fixing elements are stacked and heated.

The methods (1) and (2) above can be carried out in the substantial absence of water or in the presence of a trace amount of water.

The heating temperature in the heat development process is about to 0c to about 2zo0
It can be developed at c, but especially at about ♂0°C to about /rO'c
is useful. When heating in the presence of a trace amount of water, the upper limit of the heating temperature is below the boiling point.

When the transfer process is performed after the heat development process, the heating temperature in the transfer process can be in the range from the temperature in the heat development process to room temperature, but especially at a temperature of zo0c or higher and about 100C lower than the temperature in the heat development process. It's even better.

A preferred image forming method in the present invention is image exposure Vk
or at the same time as image exposure, heating is performed in the presence of a trace amount of water and a base and/or a base precursor, and at the same time as development, the diffusible dye generated in the area corresponding to or inversely corresponding to the silver image is transferred to the dye fixing layer. be. According to this method, the production or release reaction of the diffusible dye proceeds extremely quickly, and the movement of the diffusible dye to the dye fixing layer also proceeds rapidly, so that a high-density color image can be obtained in a short time.

The amount of water used in this embodiment is at least 0.1 times, preferably 0.1 times or more, the weight of the total coating film of the light-sensitive element and the dye fixing element, and the amount of the solvent is equivalent to the maximum swelling volume of the total coating film. A small amount of less than the weight (particularly less than the weight of the solvent corresponding to the maximum swelling volume of the entire coating film minus the weight of the entire coating film) may be sufficient.

The state of the film during swelling is unstable, and depending on the conditions, local bleeding may occur.To avoid this, the total coating film thickness of the photosensitive element and dye fixing element must be equivalent to the volume at maximum swelling. The amount of water is preferably less than the amount of water. Specifically, the total area of the photosensitive element and dye fixing element is 1)/2 per square meter.
~30ri, especially Ko f~3! t1 and even 3f-2! A range of t is preferred.

The base and/or base precursor used in this embodiment can be incorporated into both the photosensitive element and the dye fixing element. It can also be supplied dissolved in water.

In the above embodiment, the image forming reaction system contains, as a base precursor, a basic metal compound that is sparingly soluble in water and a compound that can undergo a complex formation reaction with metal ions constituting the sparingly soluble metal compound using water as a medium; Preferably, the pH of the system is raised by reaction of these two compounds upon heating. Here, the image reaction system means a region where an image forming reaction occurs. Specifically, layers belonging to both the photosensitive element and the dye fixing element can be mentioned. If there are λ or more layers, any one of them may be used.

The poorly soluble metal compound and the complex forming compound need to be added at least in separate layers in order to prevent them from reacting before the development process. For example, in a so-called monosheet material in which a photosensitive element and a dye-fixing element are provided on the same support, it is preferable that the above-mentioned two additive layers are separate layers, and seven or more layers are further interposed between them. Furthermore, a particularly preferred embodiment is one in which the poorly soluble metal compound and the complex-forming compound are contained in layers provided on separate supports. For example, it is preferable to contain the poorly soluble metal compound in the photosensitive element and the complex-forming compound in a dye fixing element having a support separate from the photosensitive element. The complex-forming compound may be supplied after being dissolved in water to be coexisting. Slightly soluble metal compounds are disclosed in Japanese Patent Application Laid-Open No. 2003-120010.
30, J3-10 Core No. 33, etc., it is desirable to contain it as a fine particle dispersion prepared by the method described in
The average particle size is preferably 20 microns or less, especially 1 micron or less. The poorly soluble metal compound may be added to any layer of the photosensitive element, such as the photosensitive layer, intermediate layer, or protective layer.
It may be added by dividing into more than one layer.

The amount of a poorly soluble metal compound or complex-forming compound to be added to the layer on the support depends on the initial draft of the compound, the particle size of the poorly soluble metal compound, the complex-forming reaction rate, etc. Convert it! It is suitable to use less than 9 cents by weight of O, and more preferably a range of 0.0/weight percent to .mu.O by weight is useful. In addition, when the complex-forming compound is dissolved in water and supplied, the amount per liter! +, 0.00! From mo I! mo
1. In particular, a concentration of O, Ojmol to -mol is preferred. Furthermore, in the present invention, the content of the complex-forming compound in the reaction system is expressed as a molar ratio to the content of the poorly soluble compound.
/ 00 to 100 times, particularly preferably //10 to 20 times.

The method for adding water to the photosensitive layer or dye fixing layer is as follows:
For example, page 10 of the patent application No. 2-2 try Jt.
There is a method described on page 10, line μ.

As heating means in the development and/or transfer process, hot plates, irons, hot rollers, etc. can be used. Tar 24
There is a means described on page 10-/Hiroyuki to page 103// line of No. 1 PJt. Alternatively, a layer of conductive material such as graphite, carbon black, metal, etc. may be applied to the photosensitive element and/or the dye fixing element, and the conductive layer may be heated directly by passing an electric current through the layer. .

The pressure conditions and method of applying pressure when overlapping the photosensitive element and the dye-fixing element and bringing them into close contact are all covered by Tokuhan Sho! The method described on pages 103 to 104 of Tar 2TR No. 26 can be applied.

0H (a) The results of examining the maximum reflected cyan density are shown in Table 7-2.

These results show that the image forming material of the present invention has a high density and can provide good images.

Furthermore, this colored sheet was subjected to a photobleaching test (/7,000 lux/4L days) using a fluorescent lamp fading tester, and the remaining dye concentration was examined relative to the initial concentration.The results were calculated as the residual rate. The values are shown in Table 73.

Table 73 The color-treated sheet was dried at 4tOoC for one week,
Thereafter, a photobleaching test similar to that described above was conducted, and the results are shown in Section 1.

Table 1 shows that the compounds of the present invention are significantly more robust to light than the comparative compounds, and the images remain vibrant even when exposed to light for long periods of time.
