No. 57-197538, a photopolymerizable composition comprising a vinyl compound and a photopolymerization initiator and a color-developing sheet coated with a microcapsule containing a dye are superposed on the image-receiving sheet after exposure, and pressure is applied to the entire sheet. And can be applied to many fields in accordance with techniques known in the art.

Methods for obtaining images using these optical recording materials include:
In general, an image is obtained by copying using an original image as an image source. For example, a method of printing an original image on a lith film by close contact exposure, a method of printing using reflected light of a document, and the like are common.

On the other hand, with the progress of computerization in recent years, there has been an increasing demand for obtaining images by using these recording materials and using digital information as an image source. To meet this demand, various laser-photosensitive photocurable compositions have been proposed. For example, JP-A-60-76,503 and U.S. Pat.
No. 4,868 (JP-A-59-45303) and JP-A-63-165,404 propose photocurable compositions sensitive to an argon laser. However, the photosensitivity of these photocurable compositions is still low, and a practical recording method is desired.

"Problems to be Solved by the Invention" It is an object of the present invention to provide a method for easily recording a digital image on a recording material having a photosensitive layer containing a photocurable composition. More specifically, an object of the present invention is to provide a method for easily recording a digital image that can be used for a color proof, a lithographic printing plate, a resin relief plate, a resist for forming a printed circuit board, a photomask, and the like.

"Means for Solving the Problems" As a result of earnest studies by the present inventors, an object of the present invention is to increase or decrease the photocuring sensitivity of the photocurable composition in the photocurable composition by at least twice or more on the support. Using a recording material having an image recording layer (hereinafter referred to as a photosensitive layer) containing a photocurable composition not containing at least one of the following, the photocuring sensitivity is measured from another layer in the recording material or from outside the recording material. This has been achieved by an image recording method characterized in that at least one of the components to be increased or decreased by a factor of two or more is image-wise moved into the image recording layer, and then the entire surface is exposed to obtain a photocured image.

In the present invention, almost all recording materials containing the photocurable composition can be used. Specific examples include a resist material for preparing a printing plate or printed circuit board provided with a layer containing the photopolymerizable composition and a binder polymer on a support, a color proof material, an optical recording heat development type recording material, vinyl A material for forming a dye image by applying a pressure to a color-developing sheet coated with a photopolymerizable composition comprising a compound and a photopolymerization initiator and a microcapsule containing a dye and exposing the image-receiving sheet after exposure to light, and the like. Can be.

Hereinafter, the present invention will be described by taking a recording material for color proof as an example for convenience, but the present invention is not limited to a method of recording on a recording material for color proof.

Various methods are known for color proofing for color proofing, and representative methods include methods described in JP-A-47-41330, JP-A-48-93337, and JP-A-51-5101. is there. That is, a method in which an image on a lithographic film is brought into close contact with a light-receiving recording material, developed, and formed into an image, and then the image is brought into close contact with an image receiving sheet, and the image is transferred by applying heat and pressure onto the image receiving sheet. .

The photocurable composition used in the recording material of the present invention comprises a polymerizable monomer and a photopolymerization initiator as main components, and if necessary, a spectral sensitizing dye, an auxiliary for promoting polymerization, and thermal polymerization. Contains inhibitors, etc.

Examples of components that increase the photocuring sensitivity by a factor of two or more include:
Examples include a photopolymerization initiator, a spectral sensitizing dye, and an auxiliary for promoting polymerization. Examples of the component that lowers the photocuring sensitivity by a factor of two or more include a thermal polymerization inhibitor.

Further, a photocrosslinkable composition may be used as the photocurable composition. At this time, as a component for increasing the photocuring sensitivity twice or more, for example, a photosensitizing dye can be mentioned.

Increase the photocuring sensitivity of the present invention by 2 times or more, or
There are various methods known in the art for moving at least one of the components to be lowered into the photosensitive layer like an image, and any of these methods may be used.

As a specific method, for example, any of a heat melting transfer method using a laser beam or a thermal head, a heat sublimation transfer method, an ink jet method, a bubble jet method, an electrophotographic method, a magnetophotographic method, and the like can be used.

At least one of the components for increasing or decreasing the photocuring sensitivity by at least twice may be present in a layer different from the photosensitive layer in the recording material, or may be used alone on a transfer sheet which is a separate sheet. May be present. When present on the transfer sheet, even if it exists in a mixed state with other compounds,
It may be emulsified, dispersed or dissolved in the binder.

In the case where a heat melting transfer method or a heat sublimation transfer method using a laser beam is used as a method for moving at least one of the components for increasing or decreasing the photocuring sensitivity into the photosensitive layer imagewise, the laser beam is used. A coloring substance such as a dye or pigment for absorbing carbon black or carbon black may coexist, or another layer containing this coloring substance may be provided. Further, a metal vapor-deposited layer may be used as a layer for absorbing the laser light.

An image according to the present invention is recorded, for example, by the following steps. (Step 1) Increase the photocuring sensitivity more than twice.
Alternatively, at least one of the components to be lowered is moved imagewise into the photosensitive layer. (Step 2) If necessary, heat the photosensitive material in order to assist the transfer of the component to the photosensitive layer.
(Step 3) Thereafter, the entire surface is exposed to obtain a photocured image. (Step 4) After this exposure, a development process is performed to obtain a desired image. For example, wash-off development, heat development, and the like are performed.

The image recording step will be further described by taking as an example a case where at least one of the components for increasing the photocuring sensitivity by a factor of two or more is imagewise moved into the photosensitive layer. Since the light sensitivity of the part where the component has moved is more than twice as high as the light sensitivity of the part where the component has not moved, when exposure is selected under appropriate exposure conditions, the part where the component has moved is photocured, and The part where the component has not moved is not photocured. Thereafter, if this recording material is subjected to a wash-off development, an image in which the portion where the component has moved remains on the support is obtained.

FIG. 1 shows an example of heating sublimation transfer using a laser beam. In this example, a laser beam is used to heat a laser beam absorbing layer on a transfer sheet, and the heat is used to record a material that can be thermally transferred in a binder and that improves the photocuring sensitivity of the photocurable composition, for example, a photopolymerization initiator. Sublimation transfer to the photosensitive layer on the material. This photosensitive layer contains a polymerizable monomer and can be photopolymerized by the action of a photopolymerization initiator. Next, the entire surface of the recording material is exposed as shown in FIG. 2, and only the portion where the material has been thermally transferred is light-cured. Thereafter, when the wash-off development is performed, a relief image in which the portion where the material has been thermally transferred remains on the support is obtained as shown in FIG.

When the material to be heat-transferred is a photopolymerization inhibitor and the photopolymerization initiator and the polymerizable monomer are present in the photosensitive layer, the photopolymerization inhibitor in the portion where the photopolymerization inhibitor has been thermally transferred is reduced. The portion where the agent has been thermally transferred is not photocured, and the portion is melted by wash-off development, so that a relief image in which the portion where the photopolymerization inhibitor has been thermally transferred is eluted is obtained as shown in FIG.

Similar results can be obtained by using a thermal head as a heating source as shown in FIG. 5 instead of the laser shown in FIG.

Further, instead of the sublimation transfer method by heating, an ink jet method shown in FIG. 6 or an electrophotographic method shown in FIG. 7 may be used as a transfer method.

Also, as shown in FIG. 8, the material to be thermally transferred may be in a layer adjacent to the photosensitive layer.

The photocurable composition of the recording material of the present invention may contain, in addition to the polymerizable compound and the photopolymerization initiator, a spectral sensitizing dye for adjusting the photosensitive wavelength. As the spectral sensitizing dye, various compounds known in the art can be used.
