Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an image recording device, more specifically, to an image recording device, in which a material on which an image produced 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 photosensitive material, overlays 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 colorant 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 material that improves these drawbacks, has high photosensitivity, and is capable of obtaining high-quality images through simple dry processing has been proposed in Japanese Patent Application No. 1986-2001 filed by the present applicant.
It is disclosed in the specification of No. 117089. In this recording 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 in the same microcapsule. It consists of a photosensitive composition encapsulated in a.

Regarding the image recording method of recording images using this photosensitive material, Japanese Patent Application No. 60-1212 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. No image recording apparatus has yet been provided that allows easy management of materials, allows highly accurate transfer of photosensitive materials without curling, and provides clear images.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and the photosensitive material is in the form of a sheet, which makes it easier to prevent so-called fogging compared to roll-shaped materials, and which can be fed using a simple feeding device. The purpose is to provide an image recording device that can.

The present invention also provides that the supplied photosensitive material does not have curling tendency,
To provide an image recording device which is free from the fear of photosensitive material jamming, is superimposed on an image receiving material with good flatness and can be transferred with high precision, and can obtain a clear image.

A further object of the present invention is to provide an image recording apparatus in which the photosensitive materials can be easily replaced and the sensitivity, dimensions, etc. of each can be changed as appropriate.

A further object of the present invention is to provide an image recording apparatus that is easy to use and has fewer protruding parts from the apparatus main body by supplying an image-receiving material in a roll.

[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,
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 in which a polymerizable compound is imagewise cured by imagewise exposure, and then pressure transfer is performed to form a visible image. The material disclosed in Japanese Patent Publication No. 57-179.836 can be used. This material consists of a vinyl compound on a support,
It supports a synthetic polymer resin wall capsule containing a photopolymerization initiator and a colorant Bricaser. Furthermore, the light-sensitive material of the present invention may be subjected to preliminary heat development or wet development before pressure transfer. As a type of product in which 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, there is a patent application filed by the present applicant in 1983. 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.
