Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an image recording device, and more particularly to a photosensitive device in which a material on which an image formed by imagewise exposure is fixed by pressure is coated on a support. The present invention relates to an image recording apparatus that, after imagewise exposing a material, overlaps the photosensitive material and an image-receiving material and transfers the image obtained on the photosensitive material to the image-receiving material under pressure.

[Technical background of the invention and its problems]

As an example of an image recording material using microcapsules encapsulating a photosensitive composition, for example, Japanese Patent Application Laid-Open No. 57-1798
A system is known in which a synthetic polymer resin wall capsule containing a vinyl compound, a photopolymerization initiator, and a coloring agent precursor is supported on a support, as disclosed in Japanese Patent No. 36. The image recording method using this system is to imagewise harden the microcapsules by exposure to light, rupture the unhardened microcapsules by applying pressure, and obtain a color image from the released colorant precursor. The method is characterized in that high quality images can be obtained through simple dry processing.

However, this system has the drawback of significantly lower photosensitivity than systems using silver halide.

A new recording paulownia material that improves these drawbacks, has high photosensitivity, and can produce high-quality images through simple dry processing11) has been proposed in a patent application filed by the present applicant. 6
It is disclosed in the specification o-++7o8q. This recording paulownia wood supports at least photosensitive silver halide,
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 comprised of a photosensitive composition encapsulated in the same microcapsule.

Regarding the double-image recording method of recording images using this photosensitive material, Japanese Patent Application No. 1212-1989 filed by the present applicant
It is disclosed in the specification of No. 84.

This image recording method first performs imagewise exposure to form a latent image, then develops it by heating, and polymerizes the polymerizable compound in the area where the latent image exists to form a macromolecular compound to form microcapsules. harden. 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.

However, using the above-mentioned photosensitive material, after imagewise exposure to this photosensitive material, the photosensitive material is overlaid with an image-receiving material and transferred by applying pressure to obtain an image on the image-receiving material, which is automatically carried out. A compact image recording device that supplies materials and image-receiving materials economically, has fewer paper jams, and has fewer protruding parts from the main body of the device has not yet been provided.

[Purpose of the invention]

The present invention has been made in view of the above circumstances, and includes:
It is an object of the present invention to provide a compact image recording device in which storage parts for photosensitive materials and image-receiving materials, etc. do not protrude from the main body of the device.

A further object of the present invention is to provide an image recording apparatus in which there is less risk of paper jams of photosensitive materials and image-receiving materials within the apparatus.

[Structure of the invention]

After imagewise exposure to a photosensitive material whose support is coated with a substance that fixes the image produced by imagewise exposure under pressure, the image obtained on the photosensitive material is superimposed on the photosensitive material and an image-receiving material. An image recording device that performs pressure transfer onto an image-receiving material, comprising: 1
. An image recording apparatus characterized in that the photosensitive material and the image receiving material are supplied in the form of a roll.

In the present invention, the photosensitive material refers to a material for obtaining a visible image by transferring an image obtained by imagewise exposure to an image receiving material having an image receiving layer under pressure.

An example of such a material is a type of material in which a polymerizable compound is imagewise cured by imagewise exposure and then pressure transfer is performed to obtain a visible image, as described in Japanese Patent Application Laid-Open No. Examples include the material disclosed in Japanese Patent No. 57-179.836. This +A material has a synthetic polymer resin wall capsule containing a vinyl compound, a photopolymerization initiator, and a coloring agent precursor supported on a support. Furthermore, the photosensitive material of the present invention may be subjected to preliminary thermal development or wet development before pressure transfer, or may be thermally developed after containing silver halide and subjected to imagewise exposure. The silver halide is developed by developing the silver halide, the polymerizable compound is simultaneously cured in correspondence with this development, and then pressure is applied to obtain a visible image. Mention may be made of the materials disclosed in Japanese Patent No. 121.284. In this light-sensitive material, at least a photosensitive silver halide, a reducing agent, a polymerizable compound, and a color image-forming substance are coated on a support, and at least the polymerizable compound and the color image-forming substance are coated on the same microorganism. It is enclosed in a capsule.
