Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light-sensitive material for forming a transferred image by utilizing a polymerization-curing reaction which occurs when developing a silver halide. In particular, the present invention relates to a highly sensitive photosensitive material for image transfer which can be drawn by scanning exposure such as laser.

[0002]

A method of forming a polymer image by imagewise exposing a light-sensitive material containing a silver halide, a reducing agent and a polymerizable compound to develop the silver halide, thereby polymerizing the polymerizable compound on the image. However, Japanese Patent Laid-Open Nos. 61-69062 and 61-73145 (US Pat.
676 and European Patent Publication No. 0174634A).
It is described in. In a typical embodiment of this image forming method, an uncured portion of a polymerizable compound containing a colorant is transferred from a photosensitive material to an image receiving material to form an image on the image receiving material. When forming a color image, a light-sensitive material containing two or more types of microcapsules (or packet emulsions) containing different colorants is used.

Although the above-mentioned light-sensitive material has high sensitivity, it destroys the microcapsules to form an image.
The resolution depends on the size of the microcapsule (usually about 10 μm or more). Further, the colorant flows out and diffuses together with the uncured polymerizable compound due to the pressure breakage of the microcapsules, which causes the image to become thick and the resolution to further decrease.

On the other hand, as a means for obtaining an image transfer with high resolution, a light-sensitive material in which a release layer is formed on a support and a photopolymerizable layer is formed thereon is known (JP-A-59).
-97140 and 61-188537). In this system, an image is once formed on a release layer on a support, and then this image is transferred together with the release layer on another support. Since the peeling layer is transferred together, the image can be transferred while maintaining high resolution.

However, since this light-sensitive material is a system in which a cured image is formed by a photopolymerization initiator, it has low photosensitivity (1/1000 or less of the light-sensitive material using silver halide) and is generally UV-sensitive. However, it does not have sufficient sensitivity to a laser light source (generally visible light to infrared light).

As described above, both types are not photosensitive materials for image transfer which satisfy both high photosensitivity and high resolution,
It is said that it is very difficult to realize a photosensitive material for image transfer which satisfies such requirements. Now, the present inventors have disclosed an image forming method and a photosensitive material using silver halide, a reducing agent, and a polymerizable compound (Japanese Patent Application No.
No. 173788, No. 3-173789, No. 3-173
790 and 3-173791). It is described in these specifications that a cured image or toner image formed with high sensitivity can be transferred onto another support. However, a release layer that has been conventionally used in a photopolymerization type light-sensitive material (image transfer was very difficult when using this release layer in a photopolymerization-type light-sensitive material) was replaced with silver halide, a reducing agent, and Even if it is used as it is in the light-sensitive material of the above-mentioned image forming method using a polymerizable compound, the image transfer is difficult and in some cases, it cannot be transferred at all.

As described above, even if the same release layer is used, in the case of a photosensitive material having a different image forming method from that of a conventional photopolymerization type photosensitive material, the image transferability is completely different. . Therefore, the light-sensitive materials disclosed in the above publications are still insufficient in terms of image transfer, and there is a demand for a light-sensitive material capable of more easily and stably transferring images.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to improve a light-sensitive material utilizing a polymerization reaction with silver halide,
It is to provide a light-sensitive material having high sensitivity and easy image transfer.

Another object of the present invention is to provide a light-sensitive material for image transfer, which can directly produce a color proof from digital image data without going through a lith film.

Since the light-sensitive material for image transfer of the present invention uses silver halide as an optical sensor, a high-sensitivity color proof can be directly prepared from digital image data without using a lith film. Silver halide
The advantage is that scanning exposure of lasers, especially long wavelength lasers, can be used as the light source. Further, in the image transfer photosensitive material of the present invention, a release layer is provided between the support and the photosensitive polymerizable layer. By providing the peeling layer, the image formed on the photosensitive material with high sensitivity using silver halide can be directly transferred to another material such as an image receiving material. Therefore, it is possible to form a clear transferred image having extremely high resolution as compared with the conventional photosensitive material for image transfer using microcapsules.

Further, in the present invention, the release layer contains a specific compound represented by the formulas (I) to (V). According to the research conducted by the present inventors, the peeling layer (composed only of a binder and a surfactant) of a conventional image transfer photosensitive material using a photopolymer is used as it is for the image transfer photosensitive material using silver halide of the present invention. When applied, either the non-image area or the image area cannot be transferred, or the non-image area (uncured area) has good releasability, but the releasability of the image area (cured area) deteriorates. It becomes clear that the image transfer becomes difficult, and sometimes the image transfer becomes impossible. Although the cause has not been clarified, it is a phenomenon peculiar to the image transfer photosensitive material using silver halide, which is not known in the image transfer photosensitive material using a photopolymer. As described above, the photosensitive material for image transfer of the present invention, in which the release layer contains the above-mentioned specific compound, solves the problem of deterioration of the releasability and can form a very clear transferred image.

[Reducing Agent] The reducing agent used in the present invention has a function of reducing silver halide or a function of accelerating (or suppressing) the polymerization of the polymerizable compound. There are various kinds of substances as the reducing agent having the above function. Examples of the reducing agent include hydroquinones, catechols, p-aminophenols, p-phenylenediamines, 3-pyrazolidones, 3-aminopyrazoles, 4-amino-5-pyrazolones, 5-aminouracils, 4,5-dihydroxy-6-aminopyrimidines, reductones, aminoreductones, o- or p-sulfonamidophenols, o- or p-sulfonamidonaphthols,

Examples include α-sulfonamidoketones and hydrazines.
By adjusting the type and amount of the reducing agent, it is possible to selectively polymerize the polymerizable compound in any portion of the silver halide latent image formed portion and the latent image not formed portion. . For example, the following system (A), (B) or (C) can be adopted.

The reducing agent (A) develops silver halide and is itself oxidized to an oxidant. When the oxidant decomposes in the layer to generate radicals, polymerization occurs in the portion where the latent image of silver halide is formed. Examples of the reducing agent having such a function include the case where hydrazines are used alone, or the case where hydrazines and other reducing agents are used in combination. (B) When the oxidant of the reducing agent has a polymerization suppressing function, by coexisting a polymerization initiator in the system, the polymerization is suppressed in the portion where the latent image of silver halide is formed. Then, polymerization occurs in the portion where the latent image of silver halide is not formed. Examples of the reducing agent having such a function include 1-phenyl-3-pyrazolidones. (C) When the reducing agent itself has a polymerization inhibiting function, but its oxidant does not have a polymerization inhibiting function (or has a weak polymerization inhibiting function), a polymerization initiator is allowed to coexist in the system. By setting, the polymerization is suppressed in the portion where the latent image of silver halide is not formed, and the polymerization occurs in the portion where the latent image of silver halide is formed. Examples of the reducing agent having such a function include hydroquinones. In the system (B) or (C) described above, it is necessary to add a polymerization initiator that decomposes to generate radicals by heating or light irradiation to any layer of the photosensitive material.

Further, as in the light-sensitive material described in JP-A-62-210446, instead of the reducing agent, a reducing agent precursor capable of releasing the reducing agent under heating conditions or in contact with a base may be used. . The reducing agent and reducing agent precursor described in the above-mentioned publications and documents can be effectively used for the light-sensitive material in the present specification. Therefore, the "reducing agent" in the present specification includes the reducing agents and reducing agent precursors described in the above-mentioned publications, specifications and literatures. Further, among these reducing agents, those having a basicity to form a salt with an acid can be used in the form of a salt with an appropriate acid. These reducing agents may be used alone, or as described in each of the above publications, two or more reducing agents may be mixed and used. When two or more reducing agents are used in combination, the reducing agent's interaction is as follows. Firstly, silver halide (and / or organic silver salt) by so-called superadditivity.
Secondly, via the redox reaction with another reducing agent in which the oxidant of the first reducing agent produced by reduction of silver halide (and / or organic silver salt) coexists. Inducing the polymerization of the polymerizable compound (or suppressing the polymerization) is considered. However, in actual use, it is difficult to specify which of the above actions because the above reactions can occur simultaneously. The reducing agent is 0.1 per mol of silver halide.
Used in the range of 10 to 10 moles, more preferably 0.5
Is in the range of up to 5 moles. Specific examples of the reducing agent are shown below.

As the binder, natural and synthetic polymer compounds can be used. As the synthetic polymer, homopolymers and copolymers of various vinyl monomers can be used among addition polymerization type synthetic polymers such as polystyrene, acrylic resin and methacrylic resin. Also, polycondensation type synthetic polymers and copolymers such as polyester, polyamide, polyurethane and polyester-polyamide can be used. When an alkaline solvent is used as the eluent described below, the binder preferably has an acidic functional group in its molecule. Examples of the acidic functional group, a carboxyl group, an acid anhydride group, a hydroxyl group,
Mention may be made of phenolic hydroxyl groups, sulfonic acid groups, sulfonamide groups and sulfonimide groups.

Specific examples of such a monomer include acrylic acid, methacrylic acid, crotonic acid, maleic acid, phthalic acid, maleic anhydride, p-carboxystyrene, p-hydroxystyrene, p-hydroxyphenylacrylamide, hydroxyethyl methacrylate, hydroxy. Ethylmethacrylamide and p
Mention may be made of vinylbenzenesulfonic acid. The amount of the binder added to the polymerizable layer is not particularly limited as long as it does not hinder the curing reaction of the polymerizable layer, but it is 0 to 80% by weight, preferably 0 to 70% by weight based on the entire polymerizable layer.

[Polymerization Inhibitor] In the case of a layered photosensitive material, a polymerization inhibitor may be added to the polymerizable layer in order to prevent a dark polymerization reaction. As the polymerization inhibitor for this purpose, any conventionally known polymerization inhibitor can be used. Examples of the polymerization inhibitor include nitrosamine compounds, thiourea compounds, thioamide compounds, urea compounds, phenol derivatives, nitrobenzene derivatives and amine compounds. More specifically, cuperon Al salt, N

Nitrobenzene, pyridine, phenathiazine, β-naphthol, naphthylamine, t-butylcatechol, phenothiazine, chloranil, p-methoxyphenol,
Mention may be made of pyrogallol, hydroquinone, and alkyl- or aryl-substituted hydroquinones.

[Organic Metal Salt] An organic metal salt can be added to the photosensitive layer of the laminated type photosensitive material together with silver halide. It is considered that the organic silver salt participates in the redox reaction using the latent image of silver halide as a catalyst upon heating, and as a result, the effect of accelerating image formation is recognized. Organic silver salts include organic acid silver salts, triazole silver salts, and the like, "Basics of photographic optics, non-silver salts" (page 247) and JP-A-59-
Organic silver salts described in JP-A Nos. 55429 and 62-3246 can be used. Specifically, it is a silver salt of an aliphatic carboxylic acid, an aromatic carboxylic acid, a thiocarbonyl group compound having a mercapto group or α-hydrogen, an acetylene compound and an imino group-containing compound. Examples of the aliphatic carboxylic acid include acetic acid, butyric acid, succinic acid, sebacic acid, adipic acid, oleic acid, linoleic acid, linolenic acid, tartaric acid, palmitic acid, stearic acid, behenic acid and camphoric acid. Generally, the smaller the number of carbon atoms, the more unstable the silver salt is, and therefore a salt having an appropriate number of carbon atoms is preferable. Examples of aromatic carboxylic acids include benzoic acid derivatives, quinolinic acid derivatives, naphthalenecarboxylic acid derivatives, salicylic acid derivatives, gallic acid, tannic acid, phthalic acid, phenylacetic acid derivatives and pyromellitic acid.

Examples of the thiocarbonyl group compound having a mercapto group or α-hydrogen include 3-mercapto-4-phenyl-1,2,4-triazole, 2-mercaptobenzimidazole, 2-mercapto-5-aminothiadiazole, 2 -Mercaptobenzothiazole, s-alkyl thioglycolic acid (alkyl group having 12 to 2 carbon atoms)
2), dithiocarboxylic acids (eg, dithioacetic acid), thioamides (eg, thiostearoamide), 5-carboxy-
1-methyl-2-phenyl-4-thiopyridine, mercaptotriazine, 2-mercaptobenzoxazole,
Mention may be made of mercaptooxadiazole and 3-amino-5-benzylthio-1,2,4-triazole. The mercapto compounds described in US Pat. No. 4,123,274 can also be used. Examples of the compound containing an imino group include benzotriazole and its derivatives,
1,2,4-triazole, 1H-tetrazole, carbazole, saccharin, imidazole and derivatives thereof can be mentioned. Benzotriazole and its derivatives are described in JP-B Nos. 44-30270 and 45-18416. Examples of benzotriazole and its derivatives include benzotriazole, alkyl-substituted benzotriazoles (eg, methylbenzotriazole), halogen-substituted benzotriazoles (eg, 5-chlorobenzotriazole), carboximidobenzotriazoles (eg, butyl). Carboximidobenzotriazole), nitrobenzotriazoles (described in JP-A-58-18639), sulfobenzotriazole (described in JP-A-58-15638), carboxybenzotriazole and salts thereof, and hydroxybenzotriazole. be able to. 1,
2,4-triazole and 1H-tetrazole are described in US Pat. No. 4,220,709.

In some cases, instead of the organic silver salt, the same effect may be obtained by adding an organic compound constituting the organic silver salt to the photosensitive layer. Two or more kinds of organic silver salts may be used in combination. The above organic silver salt is 0 to 10 per mol of silver halide.
Molar, preferably 0 to 1 mol is used. The total coating amount of silver halide and organic silver salt is 1 mg in terms of silver in the photosensitive layer.
The range of ˜5 g / m ² , preferably 10 mg to 0.5 g / m ² is suitable.

[Binder for photosensitive layer] In the case of a laminated type photosensitive material, the binder used in the photosensitive layer may be any binder as long as the characteristics of the photosensitive layer are not significantly impaired. However, since the photosensitive layer contains silver halide, it is preferable to use a hydrophilic binder. The hydrophilic binder is a binder having a hydrophilic group or / and a bond in the molecular structure. Examples of hydrophilic groups include carboxyl groups, alcoholic hydroxyl groups, phenolic hydroxyl groups, sulfonic acid groups, sulfonamide groups, sulfonimide groups and amide groups. Examples of hydrophilic bonds include urethane bonds,
An ether bond and an amide bond can be mentioned.
It is preferable to use a water-soluble polymer and / or a water-swellable polymer as the hydrophilic binder polymer.
A water-swellable polymer has an affinity for water,
The binder itself does not completely dissolve in water because it has a crosslinked structure and the like. As the water-soluble or water-swellable binder, a natural or synthetic polymer compound can be used. Examples of natural polymers include water-soluble polysaccharides (eg, starch derivatives, cellulose derivatives, alginic acid, pectic acid, gum arabic, pullulan, dextran) and proteins (eg, casein, gelatin). These may be artificially modified if necessary. It can also be used after being modified or crosslinked during coating and drying. As the synthetic polymer, a polymer of a water-soluble monomer or a copolymer of this and another monomer can be used. Examples of the water-soluble monomer in this case include a monomer having a chemical structure such as a carboxyl group, an acid anhydride group, a hydroxyl group, a sulfonic acid (salt) group, an amide group, an amino group, and an ether group. Such monomers are described in "Applications and Markets of Water-Soluble Polymers" (CMC 16-18). A copolymer obtained by polymerizing these monomers or crosslinking a polymer obtained by copolymerizing with another monomer can also be used (for example, the copolymer described in US Pat. No. 4,913,998).

As other synthetic polymers, polyvinyl alcohol, polyvinyl ether, polyvinylpyrrolidone, polyethylene oxide and derivatives or modified products thereof can be used. For example, in the case of polyvinyl alcohol, those having various degrees of saponification can be used. Further, copolymer modified polyvinyl alcohol can also be used. The copolymerization modification is a method in which a copolymer of vinyl acetate and another monomer is saponified to obtain modified polyvinyl alcohol. As the monomer to be copolymerized, any monomer can be used as long as it is copolymerized with vinyl acetate. Examples of copolymerizable monomers include ethylene, higher vinyl carboxylates, higher alkyl vinyl ethers, methyl methacrylate and acrylamide. Further, post-modified polyvinyl alcohol can also be used. The post-modification is a method in which a compound having reactivity with a hydroxyl group of polyvinyl alcohol is modified by a polymer reaction. Specifically, the hydroxyl group is modified by etherification, esterification, acetalization, or the like. Furthermore, it is also possible to use crosslinked polyvinyl alcohol. In this case, an aldehyde as a crosslinking agent,
Polyvinyl alcohol is cross-linked using a methylol compound, an epoxy compound, a diisocyanate, a divinyl compound, a dicarboxylic acid or an inorganic cross-linking agent (eg boric acid, titanium, copper). These modified polyvinyl alcohols and cross-linked polyvinyl alcohols are described in "Poval", Vol. 3, Vol. 28, pp. 281-285 and 256-26.
Page 0). The molecular weight of these hydrophilic polymers is preferably in the range of 3000 to 500,000. The coating amount is 0.05 to 20 g / m ² , more preferably 0.1.
The range is from 10 g / m ² .

Oxygen that has penetrated into the polymerizable layer during heat development inhibits radical polymerization or crosslinking. Therefore, the photosensitive layer preferably has a function of preventing the influence of oxygen in the air on the polymerizable layer. For this function, the hydrophilic binder needs to be a substance having a low oxygen permeability, and its oxygen permeability coefficient is 1.0 ×.
It is preferably 10 ⁻¹¹ cc · cm / cm ² · sec · cm · Hg or less. As the polymer having low oxygen permeability, a polyvinyl alcohol polymer, a copolymer of gelatin and vinylidene chloride is preferable. Here, the polyvinyl alcohol-based polymer means polyvinyl alcohol and modified polyvinyl alcohol (for example, saponified block copolymer of polyvinyl acetate and another monomer). The molecular weight is not particularly limited, but is preferably in the range of about 3000 to 500,000. As a polymer with low oxygen permeability, saponification degree is 5
0% or more, more preferably 80% or more, even more preferably 85% or more polyvinyl alcohol is particularly preferable.

[Heat Development Accelerator] The light-sensitive material used in the present invention may contain a heat development accelerator in any layer in order to accelerate heat development and to carry out heat development processing in a shorter time. .
It is not clear why the heat development accelerator has the above-mentioned action, but whether the heat development accelerator gives a plasticizing effect to the binder of the light-sensitive material or gives a plasticizing effect to the binder at the time of heating, By fusing in the layer, it promotes the movement or diffusion of substances that contribute to the reaction in each layer within the layer, and as a result, various reactions (decomposition of base precursor, reduction of silver halide) occurring during thermal development in the light-sensitive material. , Polymerization or curing reaction).

[Colorant] In the present invention, a colorant can be added to the light-sensitive material for the purpose of preventing halation. As the colorant for this purpose, a pigment or a pigment may be used as long as it does not significantly hinder the polymerization and curing reaction of the polymerizable layer or the light sensitivity and developability of the silver halide.
Any known colorant can be used regardless of the dye. When a colorant is added to prevent halation, the colorant must be capable of absorbing light at the exposure wavelength. As the colorant for this purpose, any substance that can be used as a colorant in the present invention can be used. When the colorant is a dye and it is contained in the photosensitive layer or a layer adjacent to the photosensitive layer, the anti-irradiation dye referred to in the silver salt photosensitive material can be used. For these anti-irradiation dyes,

The content of the colorant is not particularly limited as long as it does not significantly hinder the polymerization reaction of the polymerizable layer or the light sensitivity and developability of the silver halide. In addition, the appropriate addition amount changes depending on which layer contains the pigment, the pigment or the dye is used. Also, since the appropriate addition amount changes depending on the absorbance of the colorant,
Although it is difficult to unconditionally specify the optimum addition amount,

^{Is 2} . In the mode of forming an image using a colorant,
When a colorant is used in the polymerizable layer for a light-sensitive material, the color tone of the image changes due to the mixing of the color with the colorant, so the amount added should be kept to the minimum or the amount added to the polymerizable layer should not be added. Addition should be avoided. This is not a limitation in a mode in which an image is formed using toner. These colorants can be contained in any layer of the light-sensitive material. It is also possible to provide a new layer in the light-sensitive material such as a back layer or an intermediate layer, and introduce the new layer into these layers. It can also be added to each of a plurality of layers of the light-sensitive material. Further, two or more kinds of colorants can be used together.

[Polymerization Initiator] The reducing agent used in the light-sensitive material used in the present invention, or the oxidant of the reducing agent produced when the reducing agent reduces silver halide suppresses the polymerization of the polymerizable compound. If it is a working compound,
It is necessary to add a polymerization initiator that generates radicals by heating or light irradiation to at least one layer of the light-sensitive material. As these thermal polymerization initiators or photopolymerization initiators, conventionally known ones can be used.
When a photopolymerization initiator is used, it is necessary to irradiate the entire surface with light after thermal development. The thermal polymerization initiator is, for example, “addition polymerization / ring-opening polymerization” edited by the Society of Polymer Science and the Society for Polymer Experimental Studies Editorial Committee.

[Adhesive Layer] Depending on the mode of image formation,
An adhesive layer may be provided on the photosensitive material. The adhesive layer needs to be a layer that does not completely dissolve in the eluate during the elution operation. It must also have the ability to adhere colored toner to its surface. The adhesive layer can be constructed of any known substance as long as it satisfies the above two points. As an example of such a layer, a mixed layer of any conventionally known polymer and a compound exemplified as a substance having a plasticizing effect among heat development accelerators, or
A mixed layer of any conventionally known polymer and an oligomer of any conventionally known polymer, or a second-order transition temperature of -1
A layer containing an elastomeric polymer at 0 ° C. or lower can be mentioned. In the last example, the polymer alone can provide the necessary properties, which is advantageous, but the polymer may be used as a mixed layer in which a plasticizer, an oligomer and the like are further added. Specific examples of the polymer used in the adhesive layer include natural rubber and synthetic rubber. As an example of synthetic rubber,
Isobutylene, nitrile rubber, butyl rubber, chlorinated rubber, polyvinyl isobutyl ether, silicone elastomer, neoprene and copolymer rubber (eg, styrene-butadiene copolymer, styrene-isobutylene copolymer)
Can be mentioned. When the polymer is a copolymer, it may be a random, block or graft copolymer.
The thickness of the adhesive layer is preferably 0.01 to 10 μm,
0.05 to 5 μm is more preferable.

[Arbitrarily provided layer] Regardless of the single-layer type photosensitive material and the laminated type photosensitive material, an additional layer can be provided in any part of the photosensitive material. For example, a protective layer (or a cover film layer) for surface protection or prevention of polymerization inhibition by oxygen in the air, a back layer for preventing halation or preventing adhesion when the photosensitive materials are stored together. If necessary, an intermediate layer or the like may be provided to improve adhesion between layers or peeling property or prevent halation. Further, when performing transfer to the image receiving material or laminating with the image receiving material, in order to prevent bubbles from being unable to adhere uniformly due to inclusion of a matting agent in the layer in contact with these image receiving materials, A new layer containing a matting agent may be provided. As the matting agent in this case, a conventionally known matting agent can be used. The matting agent may be incorporated in the image receiving material. When the photosensitive material has an overcoat layer, the overcoat layer can be formed as a layer containing an arbitrary polymer by coating in advance. There is no particular limitation on the material of the polymer used for these overcoat layers. For example, a hydrophilic binder polymer that can be added to the photosensitive layer can be used. Of these, various polyvinyl alcohols are particularly preferably used. When it is desired to impart a function of reducing oxygen permeation to the overcoat layer, the saponification degree of polyvinyl alcohols is 85%.
When it is desired to impart higher oxygen impermeability to the above polyvinyl alcohol, it is preferable to use polyvinyl alcohol having a saponification degree of 95% or more. Also,
The overcoat layer is not limited to only one layer, but 2
It is also possible to stack and install more than one layer.

Next, each aspect of the image forming method using the photosensitive material for image transfer of the present invention will be described. The light-sensitive material of the present invention is preferably used for a method of transferring an image from a light-sensitive material to an image receiving material, particularly for producing a color proof.

In the transfer step or peeling step of each of the above embodiments, the peeling layer of the present invention functions to transfer the image formed on the photosensitive material with high sensitivity to the image receiving material while maintaining high resolution. it can. After the transfer image is formed on the image receiving material for a certain color as described above, the same processing is further performed for another color to form a two-color image on the image receiving material. It is also possible to form a color image on the image receiving material by repeating this operation for other colors. Among the above aspects, the release layer of the present invention is particularly effective in the first aspect and the third aspect. Hereinafter, the first aspect and the third aspect will be described in more detail with reference to the drawings.

In 2), there is no substantial change in silver halide (34).
Although the image exposure process has been described with reference to FIG. 3 using the laminated type photosensitive material shown in FIG. 2 as an example, the same process can be performed with the single layer type photosensitive material as described in FIG.

FIG. 4 is a schematic sectional view showing the developing step in the first embodiment of the image forming method. When the photosensitive material is heated (41), the reducing agent causes the polymerizable layer (42 and 43)
To the photosensitive layers (44 and 45) to develop the silver halide latent image in the exposed areas (45) of the photosensitive layer. The silver halide is developed into a silver image (49),
At the same time, the reducing agent is oxidized to form an oxidant radical (47). The oxidant radicals (47) of the reducing agent move from the exposed areas (45) of the photosensitive layer to the exposed areas (43) of the polymerizable layer. The polymerizable compound is cured by the action of this radical to form a cured portion (43). On the other hand, there is no substantial change in the reducing agent (46) contained in the unexposed portion of the polymerizable layer and the silver halide (48) contained in the unexposed portion of the photosensitive layer. The unexposed area (42) becomes an uncured area. It should be noted that although the thermal development process is described as an example in FIG. 4, a wet phenomenon process using a developing solution may be performed. Further, in FIG. 4, the system in which the polymerizable compound in the exposed area is selectively cured is described as an example, but by changing the conditions such as the type of the reducing agent as described above, the polymerizable compound in the unexposed area is changed. It is also possible to employ a system that selectively cures. Similarly, in each of the drawings for explaining the following development processing, a system in which the polymerizable compound in the heat development processing and the exposed area is selectively cured will be described as an example, but the wet development processing and the polymerizable compound in the unexposed area are A system of selective curing is of course also feasible.

As described above, a transfer image is formed on the image receiving material.

FIG. 7 is a schematic sectional view showing an exposure step in the third embodiment of the image forming method. A latent image (75) of silver halide is formed in the exposed part (73) of the photosensitive layer irradiated with light (71). On the other hand, the unexposed part (7

The polymerizable compound is cured by the action of this radical to form a cured portion (83). On the other hand, there is no substantial change in the reducing agent (86) contained in the unexposed portion of the polymerizable layer and the silver halide (88) contained in the unexposed portion of the photosensitive layer. The unexposed area (82) becomes an uncured area.

FIG. 9 is a schematic sectional view showing an elution step in the third embodiment of the image forming method. The eluate (91) is used to remove the uncured portion of the polymerizable layer, thereby forming a colored image on the cured portion (92). The photosensitive layer is peeled off and removed before the elution step, or is removed together with the uncured portion of the polymerizable layer in the elution step using an eluent.

FIG. 10 is a schematic sectional view showing a transfer step in the third mode of the image forming method. FIG. 10 shows a state after transfer. The light-sensitive material (102) is transferred to the image receiving material (10
The colored image (103) formed on the cured part of the polymerizable layer is transferred to the image receiving material together with the peeling layer (104).

The above is a typical embodiment of the image forming method using the light-sensitive material of the present invention. In image formation, in addition to the above steps, additional steps can be added if necessary. In the case of a laminated type light-sensitive material, a step of removing a layer disposed above a polymerizable layer such as a photosensitive layer is necessary before the elution step (after the development step) or at the same time as the elution step. This layer may be removed by peeling. Alternatively, the layer above the polymerizable layer may be removed by elution or swelling with a liquid that does not dissolve the polymerizable layer. Further, in the elution step, an eluent may be used to remove together with the uncured portion of the polymerizable layer. Further, the step of transferring the monochromatic image formed on the image receiving material to another image receiving material may be further performed. A step of transferring a color (multicolor) image formed on the image receiving material to another image receiving material can also be performed. When transferring an image, the image is turned over (reverse image). When the final color image is formed on the transparent support, the image may be turned over, but when the color image is formed on the opaque support, the final image needs to be formed as a desired normal image. Is. For this reason, it is necessary to appropriately perform an operation such that the exposure is performed inside out, or another transfer is performed to return the reverse image to the normal image. When adding the above-mentioned improper transfer step, it is necessary to consider such a relationship between the normal image and the reverse image. In addition, optional steps such as a step of removing additional layers such as an intermediate layer and a back layer, a matting step on the surface of the image-receiving material on which an image is formed, and a step of applying a matting agent to the image-receiving material are added. be able to.

Each step of the image forming method will be described in more detail. [Exposure Step] Image exposure in the exposure step may be performed from the surface side of the light-sensitive material (the side opposite to the support) or from the support side. Examples of the exposure method for performing image exposure include reflection image exposure using a xenon lamp, tungsten lamp, fluorescent lamp or the like as a light source, contact exposure through a transparent positive film, and laser beam, scanning exposure with a light emitting diode or the like. The light-sensitive material of the present invention is
The feature is that an image can be formed by drawing by scanning exposure. Therefore, the present invention is particularly advantageous when using scanning exposure. Scanning exposure includes helium-neon laser, helium-cadmium racer, argon ion laser, krypton ion laser, YAG laser, ruby laser, nitrogen laser, dye laser, excimer laser, semiconductor (eg, GaAs / GaAlAs, InGaAsP) laser. , Alexandrite laser, copper vapor laser,
A laser light such as an erbium laser can be used as the light source. Further, scanning exposure using a light emitting diode or a liquid crystal shutter as a light source (including a line printer type light source using a light emitting diode array, a liquid crystal shutter array, etc.) is also possible. The light source or exposure wavelength that can be used for image exposure depends on the light-sensitive region of the silver halide emulsion used in the light-sensitive material, and the wavelength region of near-ultraviolet light, visible light, and near-infrared light can be used. The amount of exposure depends on the sensitivity of the silver halide emulsion and is 0.01 to 100.
It can be exposed with light energy of 00 erg / cm ² . By performing the above image exposure, a latent image of silver halide is formed in the exposed portion.

[Developing Step] In the image forming method, it is preferable to use a dry developing process for heating the photosensitive material. The developing process can be performed at the same time as the exposing process. The imagewise exposed light-sensitive material is heated by a conventionally known heating means. For heating, the photosensitive material is brought into contact with a heated object (eg, roller, flat plate, etc.), or the photosensitive material is heated by infrared irradiation, or the photosensitive material is left in a heated zone or passed through the zone. Contact-type and non-contact-type heating means such as heating can be used. Further, at the time of heating, the surface of the light-sensitive material may be brought into close contact with an arbitrary object without being exposed to the air, and the surface may be covered and heated. The temperature and heating time required for heating depend on the characteristics of the photosensitive material used. Generally, the heating temperature is preferably in the range of 70 ° C to 200 ° C. The heating time is preferably in the range of 1 to 180 seconds. In addition, in image formation, a wet development process using a developing solution can be performed. In the developing step, the silver halide on which a latent image has been formed by exposure is developed, and at the same time, an oxidant of the reducing agent is formed at that portion. When the oxidant of the reducing agent has a polymerization accelerating effect, the exposed area is selectively cured, and when the oxidant of the reducing agent has a polymerization inhibiting effect, the polymerizable compound in the unexposed area is selectively cured. When a photosensitive material containing a photopolymerization initiator as a polymerization initiator is used in a system for curing a portion where a latent image is not formed (unexposed portion), the photosensitive material is entirely exposed after the developing step.

[Elution Step] (Third to Eighth Modes) In the developing step, the photosensitive polymerizable layer (polymerizable layer in the case of a laminated type photosensitive material) is selectively cured in exposed or unexposed areas. . As a result, the solubilities of the cured part and the uncured part with respect to the eluent change, and the cured part is not eluted with the eluent, but the uncured part is eluted with the eluent to form an image on the photosensitive material. As the eluent (or etching solution) for removing the uncured portion, any solvent can be used as long as it can remove the uncured portion of the (photosensitive) polymerizable layer. Preferably an alkaline solvent is used. The alkaline solvent is an aqueous solution containing an alkaline compound, an organic solvent containing an alkaline compound, or a mixture of an aqueous solution containing an alkaline compound and an organic solvent.
As the alkaline compound, various organic and inorganic compounds can be used. Examples of alkaline compounds include sodium hydroxide, potassium hydroxide, sodium carbonate, sodium silicate, potassium silicate, sodium metasilicate, potassium metasilicate, sodium phosphate,
Mention may be made of potassium phosphate, ammonia and amino alcohols (eg monoethanolamine, diethanolamine, triethanolamine). As the solvent of the eluate, water or various organic solvents can be used as described above. The solvent of the eluate is preferably mainly composed of water. If necessary, an organic solvent can be added to the eluate mainly containing water. As the organic solvent, alcohols or ethers are preferable. Examples of alcohols include lower alcohols (eg, methanol,
Ethanol, propanol, butanol), alcohols having an aromatic group (eg, benzyl alcohol, phenethyl alcohol), polyhydric alcohols (eg, ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol) and amino alcohols (eg, monoethanol). Amine, diethanolamine,
Triethanolamine). Examples of ethers include cellosolves. The eluate may contain a surfactant, an antifoaming agent, and other various additives as required.

[Removing Step] (Ninth to Fourteenth Modes) In the developing step, the photosensitive polymerizable layer (in the case of a laminated type photosensitive material, the polymerizable layer, the same applies hereinafter) is selectively exposed or unexposed. Hardens. As a result, the adhesive force between the photosensitive polymerizable layer and the interface of the photosensitive material on the support side changes between the uncured portion and the cured portion. When the removing sheet is brought into close contact with the surface of the photosensitive polymerizable layer of the photosensitive material, the adhesive force between the photosensitive polymerizable layer and the interface of the removing sheet also differs between the uncured portion and the cured portion. When the photosensitive material and the removal sheet are peeled off,
The adhesive force at the interface between the uncured portion and the photosensitive material support side is greater than the adhesive force at the removal sheet side, and the adhesive force at the interface between the cured part and the photosensitive material support side is greater than the adhesive force at the removal sheet side. When small, only the hardened portion is transferred to the removal sheet. Conversely, the adhesive force at the interface between the uncured portion and the support side of the photosensitive material is smaller than the adhesive force at the removal sheet side, and the adhesive force at the interface between the cured portion and the support side of the photosensitive material is at the removal sheet side. When it is larger than the adhesion, only the uncured portion is transferred to the removal sheet. Whether the cured part is transferred or the uncured part is transferred depends on the property of the polymerizable compound in the photosensitive polymerizable layer, the amount of the polymerizable compound added, the property of the binder in the photosensitive polymerizable layer, the photosensitive property. The adhesive force may vary depending on the properties of other components in the polymerizable layer and the addition amount thereof, as well as various conditions of the removal process (heating temperature, time, pressurizing temperature, etc.). . As a result of the above, the cured portion or the uncured portion selectively remains in an image form. In the ninth and tenth aspects, a color image is formed on the photosensitive material. In the eleventh and twelfth aspects, the adhesive layer is imagewise exposed, and colored toner is adhered to this to form a toner image. In the thirteenth and fourteenth aspects, the uncured portion having adhesiveness is formed in an image shape, and the colored toner is attached thereto. The removal sheet used in the removal step may be art paper, coated paper, printing paper, or plastic sheet. The surface of these may be coated with a resin binder, a plasticizer, a surface treatment agent, a matting agent, or the like in a single layer or multiple layers. The removal sheet can be made using the same material as the image receiving material described later.

In the transfer step, the release layer is transferred to the image receiving material together with the photosensitive polymerizable layer (in the case of a laminated type photosensitive material, the polymerizable layer, the same applies hereinafter). Other adjacent layers (such as an undercoat layer) may be simultaneously transferred to the image receiving material. The transfer conditions such as transfer temperature and transfer pressure in this transfer process are

It is preferably 0 kg / cm ² . In the transfer step in the first, fifth, seventh, eleventh and thirteenth aspects,

In the transfer step, what is transferred to the image receiving material is the colored toner, the photosensitive polymerizable layer and the peeling layer. Further, another layer (undercoat layer or the like) adjacent to the photosensitive polymerizable layer may be simultaneously transferred to these. The transfer temperature and transfer pressure vary greatly depending on the material of the image receiving material, the material of the colored toner, and the properties of the photosensitive material.
Generally, the transfer temperature is preferably 10 ° C. to 200 ° C., and the transfer pressure is preferably 0 to 2000 kg / cm ² . As the image receiving material used in the transfer step, art paper, coated paper, printing paper and plastic sheet can be used. The surface of these may be coated with a resin binder, a plasticizer, a surface treatment agent, a matting agent, or the like in a single layer or multiple layers.

[Evaluation of Releasability] After determining the optimum exposure amount of the obtained photosensitive material for image transfer, the releasability was quantitatively evaluated as follows. The optimum exposure amount for each image transfer photosensitive material is 3 μJ on the photosensitive surface with light passed through a 500 nm bandpass filter (half-value width 50 nm).
Was / cm ² . 4.5 cm for each photosensitive material for image transfer
After cutting into a width of 12 cm and a size of 12 cm, it was exposed with the above optimum exposure amount. Next, a thickness of 7 is applied to the overcoat layer side.
While applying a 5 μm polyethylene terephthalate film, an iron plate heated to 140 ° C. was pressed against the back surface of the support to heat it. This reduces the silver halide and simultaneously hardens the polymerizable layer. After washing the photosensitive layer and the overcoat layer with water, the polymerizable layer was immersed in an alkaline aqueous solution (DN-3C manufactured by Fuji Photo Film Co., Ltd. diluted 1/3 with water) for 60 seconds and dried at room temperature. . Since the polymerizable layer was cured, it did not dissolve in the alkaline aqueous solution (exposed sample). The sample which was not exposed was similarly heated, washed with water, immersed in the above alkaline aqueous solution for 60 seconds, and dried at room temperature. Since the polymerizable layer was not cured, it was dissolved in an alkaline aqueous solution, and only the release layer remained on the support (unexposed sample). As described above, an exposed sample and an unexposed sample were prepared for each photosensitive material for image transfer. A Mylar tape having an adhesive tape was attached to the surface of each of the obtained samples. This was subjected to a 180 degree peel test using a peel strength tester (Tensilon UTM-II-20 type, manufactured by Orientec Co., Ltd.) to measure the force required to peel the support and the peel layer ( (Fig. 1). The above results are shown in Table 1.

As shown in Table 1, in the image transfer light-sensitive material using silver halide, the unexposed sample requires a small force for peeling, but in the exposed sample, the peeling layer is
In the case of using the binder and the surfactant (Comparative Example 1), the force required for peeling was very large and the peeling could not be performed well. However, when the peeling layer contained the compound according to the present invention (Examples 1 to 11), both the unexposed sample and the exposed sample required a small force for peeling and could be peeled easily.

Next, each of the obtained photosensitive materials for image transfer was imagewise exposed through a lith film. The exposure was performed under the optimum exposure conditions described above. Next, perform development processing under the above conditions,
A sample having a cured image formed on the release layer was prepared.

On the other hand, the photosensitive material for image transfer according to the present invention, which has a peeling layer containing the specific compound according to the present invention in the above constitution (Example 1)
In the case of using (1) to (11), both the exposed and unexposed areas were easily peeled off and a good transferred image could be formed on the image receiving material.
