Description

Detailed Description of the Invention [Field of the Invention] The present invention relates to an image-receiving material used in an image forming method using a photosensitive material having a photosensitive layer containing silver halide, a reducing agent, and a polymerizable compound on a support. .

[Background of the Invention] Conventionally, image-receiving materials have been used in various image-forming methods as materials that allow images to be easily obtained through relatively simple operations such as pressure transfer when forming images using recording materials. has been done. Such image-receiving materials have various configurations depending on their uses.

For example, a support may consist of a simple support (single-layer structure), one or more layers (such as an image-receiving layer) may be provided on one side of the support, or the support may have one or more layers (such as an image-receiving layer) on one side of the support; Examples include those in which a release layer including an adhesive layer is further provided on the back surface of the support.

These image-receiving materials are used in image forming methods such as electrophotography, thermal transfer type thermal recording method, heat sublimation type thermal recording method, etc.
No. 58-88739, No. 58-88740, and No. 59-30537, and photodegradable photosensitive recording materials described in JP-A No. 58-88739. It is used in the image forming method used. In particular, it has recently been found that it can be advantageously used in image forming methods using photosensitive materials using silver halide as photosensors as described in Japanese Patent Application Laid-open Nos. 61-69062 and 61-73145. . That is, in an image forming method in which a photosensitive material having the above structure is irradiated with light to imagewise polymerize a polymerizable compound, and then a color image-forming substance is imagewise transferred to an image-receiving material together with the unpolymerized polymerizable compound. , the image-receiving material allows images formed on the photosensitive material to be easily and efficiently reproduced.

It is desirable that the image-receiving material described above be capable of transferring an image from a light-sensitive material in at least a good condition and that a peeling operation after transfer can be easily performed. It is also desirable that the transferred image obtained on the image-receiving material be of high quality.

For this reason, image-receiving materials are often subjected to treatments such as imparting smoothness to their transfer surfaces. In particular, in image formation using the above-mentioned photosensitive materials, the image-receiving material has a structure on which a support and an image-receiving layer (a layer having a specific function related to image formation and fixation) are provided. It is preferable to use This image-receiving layer is usually formed using a hydrophilic compound as a binder for the purpose of improving transfer characteristics. For this reason,
The transfer surface became sticky, making peeling operations difficult and tending to have an adverse effect on the resulting image. For example, when carrying out an image forming method, a large amount of image-receiving material 8 is prepared in advance in layers corresponding to the photosensitive material, and these are mounted on a transfer device and supplied one after another. However, adhesion occurs between the image-receiving materials, and the two sheets are supplied, causing problems such as stopping subsequent operations. In particular, there have been problems with image formation under high temperature and high humidity conditions.

[Summary of the Invention] An object of the present invention is to provide an image-receiving material in which transfer characteristics are maintained and release characteristics are improved.

Another object of the present invention is to provide an image-receiving material that can be easily expanded by preventing adhesion between image-receiving materials placed in a stacked state.

That is, in the present invention, a photosensitive material having a photosensitive layer containing silver halide, a reducing agent, and a polymerizable compound on a support is developed at the same time as the imagewise exposure, or after the imagewise exposure. An image is formed on the image-receiving material by transferring an unpolymerized polymerizable compound to the image-receiving material by pressing the photosensitive layer side of the photosensitive material and the transfer surface side of the image-receiving material in a superimposed state. In the image receiving material used in the forming method,
The image-receiving material is characterized in that a fine powder layer is provided on the surface of the image-receiving material on the transfer surface side, or on both the surface on the transfer surface side and the surface on the opposite side to the transfer surface side.

[Effects of the Invention] The image-receiving material of the present invention has a fine powder layer (a fine powder layer is included) on both the surface on the transfer surface side, the surface on the transfer surface side, and the surface on the opposite side to the transfer surface side. Because of this layer, IS operation can be performed well, and adhesion with other image-receiving materials can be effectively prevented. That is, by providing a fine powder layer, unevenness due to the contained fine powder appears on the surface of the fine powder layer, which improves the close contact with the image-receiving material at the oblique portion of the photosensitive material without deteriorating the transfer characteristics during image formation. The force is adjusted appropriately, and as a result, the peeling operation is facilitated. In particular, when forming an image using a photosensitive material to which a thermal solvent is added as an image formation accelerator to the photosensitive layer,
This is extremely effective when forming a color image in a two-component coloring system by including one of the coloring components (developer) in the image-receiving layer. In addition, in relation to other image-receiving materials in a stacked state, there are always irregularities between the image-receiving materials due to fine powder.
Since the contact area is reduced, the adhesion force is weakened and adhesion is prevented. In particular, an image-receiving material having a structure in which fine powder layers are provided on both sides of the image-receiving material has a high adhesion prevention effect.

Further, the fine powder layer according to the present invention functions advantageously in a structure having an image receiving layer on a support.

Therefore, by using the image-receiving material of the present invention, an image forming method can be carried out smoothly and excellent images can be obtained. Moreover, there is no trouble mentioned above due to adhesion, and it can be easily handled. Further, even when carrying out an image forming method using the transfer bag a, etc., it can be carried out efficiently without causing defects in the image-receiving material and without stopping the apparatus. It is particularly advantageous for image formation under high temperature and high humidity conditions.

The fine powder layer is prepared by preparing a coating solution using the above binder and fine powder using water or a suitable solvent, and applying this to the surface of the image-receiving layer opposite to the support, or between the surface and the image-receiving layer of the support. can be formed by applying it to both sides (the opposite surface) and drying it. The fine powder is generally used in a dry weight ratio of 0.01 to 1.0 relative to the amount of binder, although it varies depending on the substance constituting the binder. Preferably, it is in the range of O,l to 0.8.

The thickness of the fine powder layer thus formed is in the range of 0.1 to 10 pm. Preferably it is in the range of 0.2 to 5 pm.

By providing the above-mentioned fine powder layer, fine irregularities are always formed on the front and back surfaces of the image-receiving material, thereby preventing adhesion with other image-receiving materials.

The fine powder layer of the present invention refers to a layer in which solid particles such as a matting agent are dispersed in a binder as described above, and this layer is formed by dispersing solid particles such as a matting agent in a binder. It can also be formed by dispersing it. As such a substance, it is useful to use a high-boiling organic compound that is usually used for dispersing photographic couplers, and it is preferable that the high-boiling organic compound has a boiling point of 180° C. or higher at normal pressure, for example,

Further, a slip agent may be further applied to both surfaces of the fine powder layer (the surface of the fine powder layer opposite to the image receiving layer, 3 and the surface of the fine powder layer opposite to the support). I can do it.

Preferred anti-slip agents include higher alkyl sodium sulfate, higher fatty acid higher alcohol ester, carbon wax, higher alkyl phosphate ester, and silicone compounds. In particular, U.S. Pat.
The compounds described in JP-A No. 51-141623, as well as in JP-A-51-141623, etc., are effective alone or in combination of two or more. The amount of the above-mentioned slip agent applied to the fine powder layer is approximately 5 to 2
00 mg/rn' or appropriate.

In addition to the image-receiving materials shown in FIGS. 1 and 2, there may be mentioned, for example, a material like yE shown in FIG.

As seen in FIG. 3, one fine powder layer 14 according to the present invention is provided on the side of the back layer 15 opposite to the support 11. That is, the fine powder layer 14 is always provided on the outermost layer of the image-receiving material on the side opposite to the image-receiving layer 12.

The back layer 15 is a layer made of the binder described above, and may contain the polymer latex described above depending on the case.

Next, the image receiving layer and support will be explained.

The image-receiving layer of the image-receiving material is formed by overlapping a photosensitive material that has been subjected to imagewise exposure and development processing with the image-receiving material and applying pressure, thereby transferring the photosensitive material imagewise to the image-receiving material to form and fix an image. This layer has a mechanical moat.

The image-receiving layer can take various forms depending on the constituent components optionally included in the photosensitive layer of the photosensitive material! ,! , you can configure it as follows. Generally, the image-receiving layer is a layer containing the necessary components in a binder.

Specific components that can constitute the image-receiving layer include:
In addition to binders, color developers, mordants, thermoplastic compounds,
Examples include photopolymerization initiators, thermal polymerization initiators, dyes, and pigments.

As the binder that can be used for the image-receiving layer, the above-mentioned binder for forming a fine powder layer can be used.

Further, as in the image receiving material described in Japanese Patent Application No. 61-53879, the binder has an oxygen permeability coefficient of 1. o
x 10-” crt+'-cm/crrr'-sec・c
m Hg or less polymers may be used. When a polymer with low oxygen permeability is used as described above, the color image-forming substance transferred to the image-receiving layer is not easily deteriorated, and the image obtained on the image-receiving material is not easily damaged during long-term storage or under harsh conditions. The color hardly fades even after storage.

The binder is contained in the image-receiving layer from 1 g/m'' to 10 g/m''.
It is preferable to use it within a range of 0.7 m''.

A more preferable usage range is 0.1g/rn' to 10g
/m''.

When using a system that develops color by contacting two or more components, such as a color former and a color developer, as a coloring system for a color image forming substance, - or more of the above components are used as the color image forming substance, and the remaining One of the above components can be included in the image-receiving layer as a color developer. The above-mentioned coloring system has the advantage of providing highly sensitive and clear color images.

Systems that develop color through contact of two or more components include various systems that develop color through acid-base reactions, redox reactions, coupling reactions, chelate formation reactions, etc. between two or more components. For example, pressure-sensitive copying paper (pages 29-58), Azography (pages 87-95) described in "Introduction to Special Paper Chemistry" (published in 1975) by Hiroyuki Moriga.
Page), known coloring systems such as thermosensitive coloring by chemical change (pp. 118-120), or the preliminary proceedings of the seminar ``Latest Pigment Chemistry - Attractive Utilization and New Developments as Functional Pigments - 1'' hosted by the Kinki Chemical Industry Association. 26-32, (June 19, 1980), etc. can be used.Specifically, the partial structure of dichthone, lactam, spiropyran, etc. used in pressure-sensitive paper can be used. A coloring system consisting of a coloring agent and an acidic substance (acidic color developer) such as acid clay or phenols: aromatic diazonium salts, diazotates, diazosulfonates, and naphthols,
Systems using azo coupling reactions such as anilines and active methylenes; reactions of hexamethylenetetramine with ferric ions and gallic acid, reactions of phenolphthalein-combrecranes with alkaline earth metal ions, etc. Chelate formation reaction; redox reactions such as the reaction between ferric stearate and pyrogallol and the reaction between silver behenate and 4-methoxy-1-naphthol can be used.

In addition, as an example of a system that develops color through contact of two or more components to a light-sensitive material, there is a patent application filed in 1983.
Reaction between a leuco dye and an acidic color developer described in Japanese Patent Application No. 1987-53876: Reaction between a triazene compound, an acidic color developer, and a coupler described in Japanese Patent Application No. 1983-96339: Japanese Patent Application No. 1983
Examples include the reaction between the yellow color-forming leuco dye and an acidic color developer described in the specifications of No. 1-133091 and No. 61-133092.

When the image-receiving layer contains at least one of two or more types of components, it is preferable that the image-receiving layer contains a color developer (or a component corresponding to the color developer).

When dyes or pigments are used as the color image-forming substance, a mordant may be included in the image-receiving layer. In addition,
A photosensitive material characterized by using a dye or a pigment as a color image forming substance is described in Japanese Patent Application No. 1987-29987. The mordant that can be used in the image-receiving layer can be selected from compounds known in photographic technology and the like, taking into consideration conditions such as the type of dye or pigment. Incidentally, if necessary, two or more image-receiving layers may be constructed using a plurality of mordants having different mordant powers.

The image-receiving layer may contain a thermoplastic compound. When a thermoplastic compound is contained in the image-receiving layer, it is preferable to form the image-receiving layer itself as an aggregate of thermoplastic compound fine particles. The image-receiving layer having the above structure has the advantage that a transferred image can be easily formed, and a glossy image can be obtained by heating after image formation. The above thermoplastic compound is not particularly limited and can be arbitrarily selected from known plastic resins (plastics), waxes, and the like. However, the glass transition point of the thermoplastic resin and the melting point of the wax are preferably 200° C. or lower. Regarding an image receiving material having an image receiving layer containing thermoplastic compound fine particles as described above, Japanese Patent Application No. 61-1249
No. 52, specification 61-124953.

The image-receiving layer may contain a photopolymerization initiator or a thermal polymerization initiator. In image formation using the image-receiving material of the present invention, the color image-forming substance is transferred together with the unpolymerized polymerizable compound as described below. Therefore, a photopolymerization initiator or a thermal polymerization initiator can be added to the image-receiving layer for the purpose of smoothly proceeding with the curing process (fixing process) of the unpolymerized polymerizable compound. Further, regarding an image receiving material having an image receiving layer containing a photopolymerization initiator, see Japanese Patent Application No. 61-3025, and regarding an image receiving material having an image receiving layer containing a thermal polymerization initiator, see Japanese Patent Application No. 61-55502. There are descriptions for each.

A dye or pigment can be included in the image-receiving layer for the purpose of writing characters, symbols, frames, etc. on the image-receiving layer, or for the purpose of making the background of an image a specific color. Further, a dye or a pigment may be included in the image-receiving layer for the purpose of making it easier to distinguish between the front and back sides of the image-receiving material. As the dye or pigment, various known substances including dyes or pigments that can be used in image formation may be used, but the dye or pigment may damage the image formed in the image-receiving layer. If there is a risk, it is preferable to lower the dyeing density of the dye or pigment (for example, reduce the reflection density to 1 or less), or to use a dye or pigment that has the property of decolorizing by heating or light irradiation. . An image-receiving material having an image-receiving layer containing a dye or pigment that has the property of being decolored by heating or light irradiation is described in Japanese Patent Application No. 1983-96339.

Furthermore, when a white pigment such as titanium dioxide or barium sulfate is added to the image-receiving layer, the image-receiving layer can function as a white reflective layer. When the image-receiving layer is used as a white reflective layer, the white pigment is O, I per 1 g of the thermoplastic compound.
It is preferable to use it in a range of 100 g to 100 g.

When the dye or pigment described above is contained in the image-receiving layer, it may be contained uniformly or unevenly distributed in a portion. For example, a portion of one reflected image can be made into a projected image by constructing the support described later from a light-transmitting material and including the above-mentioned white pigment in a portion of the image-receiving layer. By doing this, image information that is unnecessary in the projected image can be written as a reflected image in the image-receiving layer portion containing the white pigment.

The image-receiving layer may be composed of two or more layers depending on the R layer as described above. Further, the layer thickness of the image-receiving layer is 1 to 1
It is preferably 100 pm, and more preferably 1 to 20 pm.

Note that it is possible to improve the releasability by incorporating the above-mentioned fine powder into the image-receiving layer. However, in practice, in order to improve the peelability, it is necessary to add a considerable amount of the above-mentioned fine powder, which, on the other hand, results in a decrease in image quality.

Materials that can be used for the support of the image-receiving material include:
Glass, paper, E-quality paper, coated paper, cast coated paper, baryta paper, synthetic paper, metals and their analogs, polyester, acetylcellulose, cellulose ester, polyvinyl acetal, polystyrene, polycarbonate, polyethylene terephthalate, etc. films, and resins. Examples include paper laminated with materials or polymers such as polyethylene.

Note that when a porous material such as paper is used as the support for the image-receiving material, it is preferable that the material has a certain degree of smoothness. Specifically, regarding the above-mentioned smoothness, the surface of the support on which the image-receiving layer is provided has a filtered waviness curve derived from a cross-sectional curve measured in accordance with JIS-B-0610 under the condition of a cutoff value of 0.8 mm. When the maximum filtering wave is measured at 100 arbitrary measurement points with a reference length of 0.2 mm, it is preferable that the surface has a surface property in which the maximum filtering wave is 4 pm or less. Regarding the image receiving material using the smooth support specified above, Japanese Patent Application No. 61-529
It is described in the specification of No. 90. Further, in order to obtain a transparent image, the support of the image-receiving material may be made of a light-transmitting material. When obtaining a transparent image, the light transmittance of the support of the image-receiving material is preferably 30% or more, and 50% or more.
% or more is more preferable. For image-receiving materials using a transparent support, please refer to Japanese Patent Application No. 61-52991.
It is stated in the specification of the issue.

For the image-receiving layer, prepare a coating solution or paint by dissolving, emulsifying, or dispersing the constituent components of the image-receiving layer using an arbitrary solvent, apply this coating solution or paint to one side of the support, and dry it. By doing this, it can be easily formed.

Although the image-receiving material of the present invention has been described using the above representative embodiments, it is as described above that any layer may be provided in the image-receiving material of the present invention.

For example, a layer made of aggregates of thermoplastic compounds may be further provided on the image-receiving layer. When a layer made of an aggregate of a thermoplastic compound is provided on the image-receiving layer, it is easy to form a transferred image, as in the case where the image-receiving layer contains a thermoplastic compound, and after image formation, It has the advantage that a glossy image can be obtained by heating. Further, the thermoplastic compounds that can be used in the layer made of aggregates of thermoplastic compounds are also the same as the thermoplastic compounds that can be included in the image-receiving layer described above. An image-receiving material in which a layer made of an aggregate of a thermoplastic compound is further provided on the image-receiving layer is described in Japanese Patent Application No. 61-55503. In this case, the fine powder layer is provided on the upper surface of the layer consisting of aggregates of thermoplastic compound. .

An image forming method using the image-receiving material of the present invention as described above will be described below.

In the image forming method using the image-receiving material of the present invention, as described above, the photosensitive material is developed at the same time as or after the imagewise exposure, and the photosensitive material and the image-receiving material are superimposed. This is done by applying pressure with the photosensitive material and transferring the image obtained on the photosensitive material onto an image-receiving material.

Various exposure means can be used as the exposure method for imagewise exposure of the photosensitive material, but generally a latent image of silver halide is obtained by imagewise exposure to radiation including visible light.

The type of light source and the amount of exposure can be selected depending on the sensitivity wavelength of silver halide (in the case of dye sensitization, the sensitized wavelength) and sensitivity. Further, the original image may be a black and white image or a color image.

When forming an image on the image-receiving material of the present invention, the photosensitive material is subjected to a development treatment simultaneously with the imagewise exposure or after the imagewise exposure. As for development processing, Japanese Patent Publication No. 45-11149,
It is also possible to perform a development process using the developer described in JP-A-47-20741, JP-A-49-10697, JP-A-57-1'38632, JP-A-58-169143, etc. In addition, JP-A-61-69 which performs heat development processing
The method described in No. 062 and 61-73145 specification is as follows:
- Since it is a dry process, it is easy to operate and has the advantage of being able to be processed in a short time. Therefore, the latter method is particularly preferable for developing photosensitive materials.

As the heating method in the heat development process, various conventionally known methods can be used. Also, JP-A-61-
Like the photosensitive material described in Japanese Patent No. 294434, the photosensitive material may be provided with a heating layer and used as a heating means. The heating temperature is generally 80°C to 200°C, preferably i
oo°C to 160°C. The heating time is generally 1 second to 5 minutes, preferably 5 seconds to 1 minute.

The photosensitive material is developed as described above, and the polymerizable compound in either the area where a silver halide latent image is formed or the area where a latent image is not formed is polymerized. In addition, in photosensitive materials, the polymerizable compound in the area where the latent image of silver halide is generally polymerized in the above-mentioned development process, but as in the photosensitive material described in Japanese Patent Application No. 60-210657, photosensitive materials are By adjusting the type, amount, etc. of the reducing agent used in the material, it is also possible to polymerize the polymerizable compound in the area where the latent image of silver halide is not formed. As described above, the polymerizable compound in the area where the latent image is formed (or the area where the latent image is not formed) can be polymerized and cured.

FIG. 4 is a schematic cross-sectional view showing a state in which an image is formed on a photosensitive material by performing a development process after imagewise exposure. Here, 21 is a support, and 22 is a photosensitive layer. The photosensitive layer 22 contains silver halide, a reducing agent, and a polymerizable compound.

As seen in FIG. 4, the photosensitive layer 22 includes a portion 3 in which a polymerizable compound is polymerized and hardened by imagewise exposure and development.
5 and a portion 36 in which the polymerizable compound is in an uncured state is generated.

Next, the above-mentioned photosensitive material is superimposed on the image-receiving material of the present invention (see FIG. 1) and pressed. Note that various conventionally known methods can be used as the pressurizing means.

FIG. 5 shows a state in which the above-obtained photosensitive material is superimposed on the image-receiving material of the present invention and pressure is applied to transfer the uncured portion 35 of the polymerizable compound onto the image-receiving material (image-receiving layer). FIG. As shown by the arrow in FIG. 5, a portion 35 of the polymerizable compound in an uncured state is transferred and formed as an image on the image-receiving layer of the image-receiving material.

After the image on the photosensitive material has been transferred in this manner, the photosensitive material is peeled off from the image-receiving material, and image formation is completed. Since the image-receiving material of the present invention has a fine powder layer provided on the upper surface of the image-receiving layer, the peeling operation can be carried out very well. Therefore, an excellent transferred image can be obtained with almost no influence on the image.

FIG. 6 is a schematic cross-sectional view showing the image-receiving material of the present invention after image formation has been completed.
