Furthermore, a method capable of polymerizing a polymerizable compound in a portion where a latent image of silver halide is not formed was disclosed in Japanese Patent Application Laid-Open No.
It is described in No. 260241. In this method, by heating, a reducing agent is caused to act on the area where the silver halide latent image has been formed, thereby suppressing the polymerization of the polymerizable compound and at the same time promoting the polymerization of other areas.

On the other hand, paper is sometimes used as a support for the image-receiving material because it is inexpensive, easily disposable, lightweight, and easy to handle. However, when an image is obtained on an image-receiving material by the above-mentioned transfer-type image forming method using a paper support, if the transfer pressure is low, the concentration of the polymerizable compound is low in the area where the polymerizable compound is to be transferred by several millimeters. There were cases where some degree of uneven transfer occurred. In addition, even if the transfer pressure is high, if the image used for imagewise exposure has gradation, if the original is exposed from the middle tone to high density area and transfer unevenness occurs in the area with low transfer density. was there.

[Summary of the Invention] An object of the present invention is to provide an image forming method in which the above-mentioned transfer unevenness hardly occurs even though a paper support is used as an image-receiving material.

In the present invention, a photosensitive material comprising a photosensitive layer containing silver halide, a reducing agent, and a polymerizable compound is provided on a support, and a latent image of silver halide is formed by imagewise exposure. At the same time or after imagewise exposure, development is performed, and an image receiving material having an image receiving layer on a paper support is superimposed on the developed photosensitive material and pressure is applied to the unpolymerized polymer. An image forming method for transferring a chemical compound to an image-receiving material, wherein the paper support of the image-receiving material has a total coefficient of variation of a laser light transmittance distribution curve obtained by He--Ne laser scanning of 15% or less. The present invention provides an image forming method characterized in that the paper support uses a base paper having a texture distribution.

Furthermore, the present invention imagewise exposes a photosensitive material comprising a photosensitive layer containing a photopolymerizable composition or a photopolymerizable compound on a support, and then applies paper to the imagewise exposed photosensitive material. An image forming method in which an unpolymerized photopolymerizable composition or a photopolymerizable compound is transferred to an image-receiving material by pressing an image-receiving material having a 4T image-receiving layer layered on a support, the method comprising: The paper support of the image-receiving material was scanned with a He-Ne laser to give an image of 11? The present invention also provides an image forming method characterized in that the paper support uses a base paper having a texture distribution such that the total variation coefficient of the laser light transmittance distribution curve is 15% or less.

Note that the present invention has particularly remarkable effects in embodiments using a photosensitive material containing silver halide and a polymerizable compound in microcapsules, or a photosensitive material containing a photopolymerizable composition or a photopolymerizable compound in microcapsules. There is.

[Effects of the Invention] The image forming method of the present invention is characterized in that a base paper having the above-described texture distribution is used as the paper support of the image-receiving material.

Through research conducted by the present inventors, it has been found that the occurrence of transfer unevenness that appears to occur at high speed when using an image receiving material having a paper support is
This problem can be solved by using a paper support using a base paper having the above-defined uniform texture distribution. In other words, if a base paper with uneven texture distribution is used,
If the pressure at the time of transfer 71 is low, or if the image used for imagewise exposure has gradation even if the transfer pressure is high,
It has been found that unevenness in the transfer pressure valve IIT occurs due to uneven formation, and as a result, unevenness in transfer occurs on the image-receiving material as if it were traveling at a high speed.

In the image forming method of the present invention, He
- Because we use a base paper with a uniform texture distribution such that the total variation coefficient of the laser light transmittance distribution curve obtained by Ne laser scanning is 15% or more, uneven transfer occurs even in the case of 1νf as described above. It is possible to obtain a clear transferred image.

Note that in the embodiment of using a photosensitive material containing silver halide and a polymerizable compound in microcapsules, or a photosensitive material containing a photopolymerizable composition or a photopolymerizable compound in microcapsules, transfer during image formation is required. The uncured microcapsules (the ITj-polymerizable compound, the photopolymerizable composition, or the photo-11-polymerizable compound are in an unpolymerized state) are destroyed by pressure. Therefore, in the embodiment using microcapsules as described above, if unevenness occurs in the transfer pressure distribution, unevenness also occurs in the broken state of the microcapsules, so that the transfer unevenness is further amplified. When the paper support according to the present invention is used as a support for an image-receiving material, it is possible to reduce the occurrence of unevenness in the fracture state of the microcapsules. As a result of the above, the present invention can obtain particularly remarkable effects in the embodiment using microcapsules as described below.

[Detailed Description of the Invention] The image-receiving material used in the image forming method of the present invention is struck onto a paper support. In this specification, "r-paper support" refers to base paper whose main component is wood pulp (r-base paper in this specification i!F).
(abbreviated as ), or a sheet-like product in which a coating layer of a certain amount is provided on a base paper.

The base paper used for the paper support of the image-receiving material of the present invention is He-N
It has a formation distribution such that the total variation coefficient of the laser light transmittance distribution curve obtained by e-laser scanning is 15% or less. In the present invention, the total coefficient of variation of the laser light transmittance distribution curve obtained by the above He-Ne laser scanning is the value of the total variation rate (%) measured using a sheet formation desk manufactured by Toyo Seiki Seisakusho ■. 1- An outline of the measurement method using the sheet formation tester is described below.

The sheet formation tester device consists of an optical section (laser light source, mirror, detection element, etc.) and a measurement section (No. 111 amplification/conversion, analysis A/D conversion, data processing, etc.).

A He-Ne laser (λ=632.8 nm) is used as a light source, and the laser beam is focused by a collimating lens and is applied to a vibrating mirror via a reflecting mirror.

A light beam swung left and right by a vibrating mirror that vibrates with a triangular wave with a frequency of 6.25 Hz is reflected parallel and perpendicularly by a scan mirror (arc-shaped mirror), and scans the surface of the sample paper placed on a reciprocating stage. .

The spot diameter of the light beam scanning the page is approximately 0.
．． Since the stage moves at a constant speed with a width of 160 mm at 1 mm, its locus has a triangular wave shape.

Furthermore, the light beam transmitted through the paper is incident on a light receiving element (silicon photocell) attached at the top.

The light receiving element converts fluctuations in transmitted light into electric current. The detection signal waveform becomes a complex waveform containing various frequency components due to variations in surface area (i) of each portion of the paper scanned by the light beam (ground unevenness). This waveform is the formation signal that represents the formation, and if the scanning speed of the light spot of the beam is V based on this formation signal, the formation unevenness can be expressed as wavelength 1, so the corresponding frequency f is as follows. It can be determined by formula (I).

f=v/11 ()Iz) (I) The device converts the current obtained by the light receiving element as a ground signal into voltage, amplifies it, and corrects the level.
The signal is passed through a filter arranged in 1/3 octave between 00Hz and decomposed into frequency components corresponding to each wavelength, representing the magnitude of the unevenness as a wavelength.

Through this frequency analysis, the size of the unevenness was found to be 80 mm (251

It is preferable that the total coefficient of variation of each filter distribution curve obtained by passing through each of the 25, 32, 40, 50, 63 and 80 mm filters is 7% or less.

Further, it is more preferable that the total variation coefficient of each of the above-mentioned filtering distribution curves is 5% or less. The total coefficient of variation (TOTAL') of each of the above filtering distribution curves is:
Determined by F description (■°).

There is also a description in the Monthly Issue, Volume 23, No. 12 (Reprint of Volume 273).

Hereinafter, the structure of the paper support used in the present invention and specific means for keeping the formation distribution within a specified range of sailing speed will be explained.

It is preferable to use a large amount of P. In particular, LBSP has a high short fiber content even before beating, and is easily converted into short fibers by beating.
And/or quintuple LDP,! It is preferable to use 7% or more. However, in order to maintain paper strength as a paper support, the amount of LBSP and/or LDP used is 6
It is preferable that the weight is 0 weight or less.

If necessary, a part of the wood valve may be replaced with other plant fiber valves such as straw, esparto, bagasse, or kenaf, synthetic valves made of polyethylene, polypropylene, etc., or synthetic fibers made of vinylon, polyester, acrylic fibers, etc. may be replaced with

In valve beating, the freeness is 20 according to the C3F standard.
It is preferable to beat it so that it becomes 0 to 400 cc, and it is more preferable to beat it so that it becomes 250 to 350 cc. As the beating machine, it is preferable to use a beater, a conical refiner, or a disc refiner. Particularly preferred is a stain-redundant type conical refiner.

The fiber length distribution defined by J 15-P-8207 (Test method for papermaking valve sieve content) is determined by thoroughly disintegrating a 10 g sample (absolutely dry weight) using a standard disintegrator.

Each residue in four layers of 150 mesh (105 μm) was determined as a percentage (weight: 4%) of the original sample weight. Therefore, a small amount of 24 mesh residue and 42 mesh residue means that the long fiber content is small in the base paper.

It is preferable to internally add a dispersant to the base paper. Examples of preferred dispersants include polyethylene oxide, hydroxyethyl cellulose, and polyacrylamide.

By using the above-mentioned base paper manufacturing method, particularly adjusting the fiber length distribution of the base paper, using a dispersant, adjusting the paper making method, etc., the texture distribution of the base paper to be manufactured can be determined by laser scanning obtained by He-Ne laser scanning. The total coefficient of variation of the light transmittance distribution curve is 15% or less! “It can be i.

Examples of such hydrophobic polymers include vinylidene chloride, styrene-butadiene copolymer, methyl methacrylate-butadiene copolymer, acrylonitrile-butadiene copolymer, styrene-acrylic ester copolymer, methyl methacrylate-acrylic ester copolymer, and styrene. -Methacrylate-acrylic acid ester copolymer, etc. can be mentioned.

It is further preferable that the hydrophobic polymer has a crosslinked structure. In order to form a crosslinked structure in a hydrophobic polymer, a known curing agent (crosslinking agent) may be used together with the hydrophobic polymer during production of the paper support.

In the following margin, the image receiving layer provided on the paper support as described above will be explained.

The image-receiving layer can be constructed in any desired form using various compounds according to the coloring system of the color image-forming substance described below.

For example, when using a coloring system consisting of a color former and a color developer, the image receiving layer can contain the color developer. Further, the image-receiving layer can also be configured as a layer containing at least one mordant. The mordant can be selected from compounds known in the photographic technology, taking into consideration conditions such as the type of color image forming substance, and used. Note that, if necessary, two or more image-receiving layers may be constructed using a plurality of mordants having different mordant powers.

The image-receiving layer preferably contains a polymer as a binder. As the binder, binders that can be used in the photosensitive layer of the photosensitive material described above can be used. Further, as in the image-receiving material described in Japanese Patent Application No. 61-53879, a polymer with low oxygen permeability may be used as the binder.

For the image receiving layer, Japanese Patent Application No. 61-124952 and No. 61
-124953, each specification -F as described in the image receiving material,
Fine particles of thermoplastic compounds may also be included. Furthermore, a white pigment such as titanium dioxide may be added to the image-receiving layer so that the image-receiving layer functions as a white reflective layer. Furthermore, the unpolymerized polymerizable compound is polymerized in one layer [in one step, a photopolymerization initiator or a thermal polymerization initiator may be added to the image-receiving layer. For an image receiving material having an image receiving layer containing a photopolymerization initiator, see Japanese Patent Application No. 61-3025, and for an image receiving material having an image receiving layer containing a thermal polymerization initiator, see Japanese Patent Application No. 61-555.
Each is described in the specification of No. 02.

Note that when the image-receiving layer is located on the surface of the image-receiving material, it is preferable to further provide a protective layer. Also, the special application 1986-
As in the image-receiving material described in No. 55503, a layer made of aggregates of fine particles of a thermoplastic compound may be provided on the image-receiving layer.

The image-wise exposure of the photosensitive material, the development process, and the transfer of the image to the image-receiving material in the image forming method will be sequentially described above.

Although various exposure means can be used for imagewise exposure of the photosensitive material, a latent image of silver halide is generally 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 wavelength to which silver halide is sensitive (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.

In addition, in a photosensitive material using a photopolymerizable composition or a photopolymerizable compound, the polymerizable compound in the exposed portion by the imagewise exposure is polymerized.

A photosensitive material having a photosensitive layer containing silver halide is subjected to a development treatment simultaneously with or after the imagewise exposure. The photosensitive material may be developed using a developer described in Japanese Patent Publication No. 45-11149. In addition, as mentioned above, JP-A No. 61-69062, which performs heat development processing,
Since the method described in the publication is a dry treatment, it is easy to operate and has the advantage of being able to perform the treatment in a short time.

Therefore, the latter method is particularly excellent for developing photosensitive materials.

As the heating method in the above heat development treatment, various conventionally known methods can be used. Further, as in the photosensitive material described in the above-mentioned Japanese Patent Application No. 135568/1980, a heat generating layer may be provided on the photosensitive material and used as a heating means. Further, as in the image forming method described in Japanese Patent Application No. 61-55506, heat development may be carried out while suppressing the amount of oxygen present in the photosensitive layer. The heating temperature is generally 80°C to 200°C, preferably 100°C to 200°C.
It is t a o ℃. The heating time is generally 1 second to 5 minutes, preferably 5 seconds to 1 minute.

A photosensitive material having a structure in which the photosensitive layer contains silver halide is subjected to a heat development process as described above, and the polymerizability of the portion where a silver halide latent image is formed or the portion where a silver halide IF image is not formed is determined. The compound can be polymerized.

In light-sensitive materials, the polymerizable compound in the area where the latent image of silver halide is generally polymerized in the heat development process, but as in the light-sensitive material described in the above-mentioned Japanese Patent Application No. 60-210657, Furthermore, by adjusting the type, amount, etc. of the transition agent, it is also possible to polymerize the polymerizable compound in the portion where the latent image of silver halide is not formed.

In the manner described above, a polymer image can be obtained on the photosensitive layer. A dye image can also be obtained by fixing dyes or pigments to the polymer.

When the photosensitive material is structured like the photosensitive material described in the aforementioned Japanese Patent Application No. 61-53881, the microcapsules containing the color image forming substance are destroyed by applying pressure to the photosensitive material that has been subjected to the development process. However, a color image can be formed on a light-sensitive material by bringing the color image-forming substance into contact with an acidic color developer and a coupler.

However, in an image forming method using a photosensitive material, it is preferable to use an image-receiving material in combination to form an image on the image-receiving material.

The photosensitive material is imagewise exposed and/or developed as described above, and the image-receiving materials are stacked and pressed to transfer the unpolymerized polymerizable compound to the image-receiving material. Polymer images can be obtained. Regarding the above-mentioned pressurizing means, various conventionally known methods can be used.

Further, in an embodiment in which the photosensitive layer contains a color image forming substance,
Similarly, the polymerizable compound is polymerized and cured by imagewise exposure and/or development treatment, thereby immobilizing the color image-forming substance in the cured portion. By pressing the photosensitive material and the image-receiving material in a superimposed state, the uncured portion of the color image-forming substance is transferred to the image-receiving material, and a color image can be formed on the image-receiving material 1.

After forming an image on the image-receiving material as described above, the image-receiving material may be heated as in the image forming method described in Japanese Patent Application No. 61-55501. In the above method, an unpolymerized IR compound transferred onto an image-receiving material is polymerized,
This has the advantage that the storage stability of the obtained image is improved.

The present applicant has already filed patent applications for various image recording apparatuses suitable for carrying out the above-described series of image forming methods using photosensitive materials. Typical of these devices are an exposure device that forms a latent image by imagewise exposure, a heat development device that hardens and immobilizes the portion corresponding to the formed latent image, and a developed photosensitive device that A transfer device that superimposes an image-receiving material on a material and presses them (Japanese Patent Application No. 60-289703);
and a structure in which a fixing device for at least irradiating light, applying pressure, or heating the image-receiving material onto which an image has been transferred is attached to the above structure (Japanese Patent Application No. 60-2897
No. 03 Specification).
