Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording method for recording color images using a photosensitive material having on a support a substance capable of fixing an image formed by exposure under pressure. .

[Conventional technology]

As a series of image recording materials using microcapsule gold containing a photosensitive composition, for example, Japanese Patent Application Laid-Open No. 57-1798
A system is known in which synthetic polymer m+ finger wall capsules containing a vinyl compound, a photopolymerization initiator, and a colorant precursor are supported on a support, as disclosed in Japanese Patent No. 56. 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 can obtain high-quality images through simple dry processing is disclosed in Japanese Patent Application Laid-Open No. 1983-1992 filed by the present applicant.
It is disclosed in Japanese Patent No. 275742. 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 encapsulated in the same microcapsule. It consists of a photosensitive composition.

Regarding the image recording method of recording images using this photosensitive material, Japanese Patent Application Laid-Open No. 61-2788 filed by the present applicant
It is disclosed in Publication No. 49. 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 areas where no latent image exists, and the color image-forming substance is transferred to the image-receiving material. to obtain an image on an image-receiving material.

Then, using the above-mentioned photosensitive material, this photosensitive material is subjected to imagewise exposure, heat development is performed, and then the image recording material is overlaid with an image-receiving material and pressed, and an image is obtained on the image-receiving material by transfer, which is automatically performed. Device? □'t is disclosed, for example, in Japanese Patent Application No. 1983-51896 filed by the present applicant.

[Problem that the invention seeks to solve]

In order to miniaturize such an image recording device, ii! is equipped with a SELFOC lens in the exposure device. J-image recording devices have been proposed. Since the SELFOC lens has a short heating point distance, even if the distance between the original and the photosensitive material is narrowed, it can be placed between the original and the photosensitive material, and good exposure can be performed.

However, since exposure apparatuses equipped with SELFOC lenses are small, they are likely to be equipped with various color density filters, and there is a problem in that sufficient color correction cannot be performed.

SUMMARY OF THE INVENTION Therefore, it is an object of the present invention to solve the above-mentioned problems, and to provide an image recording method that can perform good color correction even when exposure is performed using a SELFOC lens.

[Means and effects for solving the problems] The above object of the present invention is to record a color image using a photosensitive material having on a support a substance capable of fixing an image produced by imagewise exposure under pressure. The method comprises scanning an original and the photosensitive material placed through an exposure device having a SELFOC lens multiple times with respect to the exposure device to perform multiple exposures, and color-separating the light at each exposure. This is achieved by an image recording method characterized by performing monochrome exposure for each color.

In other words, by color-separating the light and performing monochrome exposure in a single exposure process, color density correction using a light source or color density filter is easy, and by performing exposure for each color, a full-color image can be exposed. Can be done. here,
In order to carry out monochromatic exposure, measures are taken, for example, to appropriately arrange a monochromatic filter between the light source and the photosensitive material, or to control the wavelength of the light source according to the color.

In the present invention, the photosensitive material refers to a material for obtaining a visible image by applying pressure to a latent image generated by imagewise exposure.

An example of such a material is a type of material in which a polymerizable compound is imagewise cured by imagewise exposure, and then a visible image is obtained by applying pressure, as disclosed in Japanese Patent Application Laid-Open No. 57-1991 filed by the present applicant. The material disclosed in Japanese Patent No. 179836 is mentioned. This material has a synthetic polymer resin wall capsule containing a vinyl compound, a photopolymerization initiator, and a colorant precursor supported on a support.

Also 1. After containing silver halide and imparting imagewise exposure, heat development is performed to develop the silver halide, the polymerizable compound is simultaneously cured in correspondence with this development, and then pressure is applied to form a visible image. An example of the material that can be obtained is the material disclosed in Japanese Unexamined Patent Application Publication No. 1982-27-742 filed by the present applicant.

Note that the image recording apparatus for carrying out the method of the present invention is one that has a heat development device when using a type of photosensitive material that performs heat development before fixing the image by applying pressure. When using a type that does not perform this process, it means a type that does not have a heat developing device.
