Abstract

PURPOSE:To use an optional sheet material such as ordinary paper and a photosensitive material so as to record an image by integrally equipping an image receiving material producing device which applies an image receiving layer forming solution on the sheet material and dries it. CONSTITUTION:A container 418 housing the solution 416 for forming an image receiving layer on the sheet material D is equipped ahead of conveying rolls 408 on an insertion port side on a conveying belt 414 and it drops a proper quantity of the solution 416 onto the sheet material D which is conveyed with the conveying belt 414 from the hole of the lower part of the container. A wire bar 420 obtained by closely winding a wire in a coil shape is disposed ahead of the container 418 and it moves back and forth in a direction shown by an arrow B so as to uniformly apply the solution 416 dropped on the sheet material D by the thickness of 30mum. An infrared-ray heater 422 is disposed ahead of the wire bar 420 so that the solution 416 which is uniformly applied on the sheet material D is heated to be dried. Thus, the image recorded on the photosensitive material can be transferred and recorded on the optional sheet material.

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording device that transfers an image obtained by imagewise exposure of a photosensitive material to an image-receiving material.

[Conventional technology]

As an image recording device, Japanese Patent Application Laid-Open No. 6
There is one disclosed in Japanese Patent No. 1-278849.

This image recording device first performs imagewise exposure on a photosensitive material to form a latent image, then develops it by heating, and polymerizes the polymerizable compound in the area where the latent image exists to generate a polymer compound. to harden the microcapsules. Then, the image-receiving material having an image-receiving layer to which the color image-forming substance can be transferred is stacked and pressurized to rupture at least a portion of the microcapsules in the area where the latent image does not exist, and the color image-forming substance is transferred to the image-receiving material. to obtain an image on an image-receiving material.

The image-receiving material used in the above-mentioned image recording apparatus has a support coated with an image-receiving layer-forming solvent to which a color image-forming substance on the photosensitive material can be transferred. Therefore, a ready-made sheet-shaped image-receiving material or a roll-shaped image-receiving material suitable for the recording size is used.

[Problem that the invention seeks to solve]

However, ready-made image-receiving materials are limited in size, thickness, material, etc., and therefore the use of the obtained recorded material is also limited.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide an image recording apparatus that can record images using any sheet material such as plain paper and the above-mentioned photosensitive material.

(Means and effects for solving the problems) The above-mentioned object of the present invention is to provide an image recording apparatus for transferring an image obtained by imagewise exposure of a photosensitive material to an image-receiving material, which forms an image-receiving layer on a sheet material. This is achieved by an image recording apparatus characterized in that it is integrally equipped with an image-receiving material manufacturing device that applies a solvent and dries it.

That is, by providing the image-receiving material manufacturing device, any sheet material can be easily used as an image-receiving material, and an image can be recorded on any sheet material without using a ready-made image-receiving material.

As the image-receiving layer forming solvent in the present invention, various substances are appropriately selected and used depending on the photosensitive material used.

Specifically, binders, mordants, various additives, etc. are used.

The binder is preferably hydrophilic, and transparent or translucent hydrophilic colloids are typical.

For example, natural substances such as proteins such as gelatin, gelatin derivatives, and cellulose derivatives, polysaccharides such as starch and gum arabic, and synthetic polymeric substances such as water-soluble polyvinyl compounds such as polyvinylpyrrolidone and acrylamide polymers can be used. can.

The binder may also contain an inorganic or organic hardener. For example, chromium salts (chromium alum, chromium acetate, etc.), aldehydes (formaldehyde, glyoxal, geltaraldehyde, etc.), N-methylol compounds (dimethylol urea, methylol dimethylhydantoin, etc.), dioxane derivatives (2,3-dihydroxydioxane, etc.) etc.), activated vinyl compounds (1,3,5-)
Liacryloyl-hexahydro-S-triazine, 1.
3-vinylsulfonyl-2-propatol, 1, 2-
bis(vinylsulfonylacetamido)ethane, etc.), active halogen compounds (2,4-dichloro-6-hydroxy-s-triazine, etc.), mucohalogen acids, (mucochloric acid, mucophenoxychloroic acid, etc.), etc., singly or in combination. It can be used as

Next, the mordant can be arbitrarily selected from commonly used mordants, but polymer mordants are particularly preferred.

Examples of the polymer mordant include polymers containing a tertiary amino group, polymers having a nitrogen-containing heterocyclic moiety, and polymers containing these quaternary cation groups.

Additives include bases and/or base precursors to promote dye transfer, hydrophilic heat solvents, anti-fading agents to prevent fading of dyes, UV absorbers, slip agents, matting agents, antioxidants, and anti-fading agents. Dispersed vinyl compounds, optical brighteners, etc. can be used to increase the degree of stability.

Specific examples of these additives can be found in Research Disclosure Magazine ■o1.170.RD/7029, June 1978.

For example, there are so-called heat-developable photosensitive materials in which an image obtained by thermal development is transferred to an image-receiving material by heating.

This heat-developable photosensitive material is one in which a mobile dye is released in an image-like manner by heating, and the mobile dye is transferred to an image-receiving material (dye-fixing material) having a mordant using a solvent such as water. , transfer to the image receiving material is performed using a high boiling point organic solvent, transfer is performed to the image receiving material using a hydrophilic thermal solvent contained in the image receiving material, or the mobile dye is thermally diffusible or sublimable, Those that transfer to dye-receiving materials such as supports are known, and specifically, U.S. Tokukitsuki No. 4,463,079 and No. 4,474

Another example is a so-called photosensitive pressure-sensitive material in which a visible image is obtained by transferring an image generated by imagewise exposure to an image-receiving material having an image-receiving layer by pressure.

This photosensitive and pressure sensitive material can be used, for example, by curing a polymerizable compound imagewise by imagewise exposure as disclosed in JP-A-57-179836 filed by the present applicant, and then overlaying it with an image-receiving material and applying pressure. There is a type that obtains a visible image by adding This photosensitive and pressure sensitive material has a synthetic polymer resin wall capsule containing a vinyl compound, a photopolymerization initiator, and a colored precursor supported on a support.

Further, there is a type in which a visible image is obtained by preliminary thermal development or wet development of a latent image generated by imagewise exposure, and then overlapping it with an image-receiving material and applying pressure. Examples of such materials include Japanese Unexamined Patent Application Publication No. 1983-1981 filed by the present applicant.
There is one disclosed in Japanese Patent No. -278849.

This material is used to obtain an image on an image-receiving material by transferring a color image-forming substance to an image-receiving material having an image-receiving layer after thermal development.
A reducing agent, a polymerizable compound, and a color image-forming substance are coated, and at least the polymerizable compound and the color image-forming substance are encapsulated in the same microcapsule.
