Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention is characterized in that: KfI! is applied to a support by applying a material on which an image produced by imagewise exposure is fixed by pressure; The present invention relates to an image recording apparatus which, after imagewise exposing a photosensitive material which has been used as an i-layer, 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 cure the microcapsules with XIN light, rupture the uncured microcapsules with 1270 pressure, and obtain a color image from the released colorant precursor.
This method has the feature 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 which improves these drawbacks and has high photosensitivity and can obtain high quality images through a simple dry process is disclosed in Japanese Patent Application Laid-Open No. 1983-1981 filed by the present applicant.
No. 275,742. In this recording material, at least a photosensitive silver halide reducing agent, a polymerizable compound, and a color image-forming substance are coated on a support, and at least the polymerizable compound and color image-forming substance are encapsulated in the same microcapsule. It consists of a photosensitive composition.

Regarding the image recording method of recording images using this photosensitive material, please refer to Japanese Patent Application Laid-Open No. 61-278 filed by the present applicant.
No. 849.

This image recording method first performs imagewise exposure to form a cape image, then develops it by heating, and polymerizes the polymerizable compound in the area where the latent image exists to form a macromolecular compound into microcapsules. harden. Then, it is overlapped with an image-receiving material having an image-receiving layer to which the color image-forming substance can be transferred, and pressed together to rupture at least a part of the microcapsules in the areas where no latent image exists, and the one-color image-forming substance is transferred to the image-receiving material. image on the receiving fA material.

Then, using the above-mentioned photosensitive material, this photosensitive material is subjected to imagewise exposure, heat development, and then superimposed on an image-receiving material and pressurized to obtain an image on the image-receiving material by transfer, which is automatically performed. A recording device is disclosed in, for example, Japanese Patent Laid-Open No. 51896/1989 filed by the present applicant.

[Problem that the invention seeks to solve]

However, when an image is recorded using the above-mentioned photosensitive material, for example, the color forming agent component contained in the photosensitive material and the color developer contained in the image receiving material undergo an acid-base reaction, an oxidation-reduction reaction, a coupling reaction, Because color develops through a chemical reaction such as a chelate formation reaction, the image obtained on the image-receiving material immediately after the 2 km pressure transfer is not completely colored, and the image obtained is not completely colored until sufficient color is obtained as a recorded material. The problem is that it takes a long time.

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 promote color development of an image on a photosensitive material transferred from a photosensitive material.

This is achieved by an image recording apparatus characterized in that it has a post-heating device for heating the image.

In other words, by heating the image transferred onto the image-receiving material, a chemical reaction is accelerated and color development is accelerated, and a predetermined image density is achieved in a short time, and the main image is recorded using a material containing a polymerization initiator during recording. When an image is recorded using the apparatus, unpolymerized heptads are polymerized, and the stability of the image over time is also improved.

Examples of oxybenzoic acid esters include ethyl p-oxybenzoate, butyl p-oxybenzoate SP-heptyl oxybenzoate, and benzyl p-oxybenzoate.

Furthermore, in the present invention, the term "photosensitive material" refers to a material for obtaining a visible image by applying pressure to a latent image generated by single-imagewise exposure.

An example of such a material is one in which a polymerizable compound is imagewise cured by imagewise exposure and then a visible image is obtained by applying pressure, as described in 1. Examples include the material disclosed in Japanese Patent No. 57-179836. This material has a synthetic polymer resin wall capsule containing a vinyl compound, a photopolymerization initiator, and a colorant precursor supported on a support.

In addition, after containing silver halide and giving imagewise exposure, heat development is performed to develop the silver halide, and corresponding to this development, the polymerizable compound is simultaneously cured (71), and then pressure is applied to form a visible image. As a material of the type that obtains the above-mentioned materials disclosed in Japanese Patent Application Laid-open No. 61-278,849 filed by the non-applicant mentioned above,
The material disclosed in No. 49 is one in which a color image-forming substance is transferred to an image-receiving material having an image-receiving layer after thermal development to obtain an image on the image-receiving material. Silver, a reducing agent, an N-compound, and a color image-forming substance are coated and the polymerizable compound and the color image-forming substance are encapsulated in the same microcapsule.
