Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a transfer material used mainly for color proofing, displays, etc. for color proofing. More specifically, the present invention provides a transferable image formed on a photosensitive transfer material in which a release layer made of an organic polymer, a coloring material layer, and a photosensitive layer are sequentially laminated on a temporary support. It relates to a photosensitive transfer material which can be advantageously used in an image forming process comprising first transferring onto an image receiving sheet and then retransferring the image onto a permanent support.

[Background of the Invention] A photosensitive transfer material consisting of a temporary support, one layer of 'Aa, a coloring material layer, and a photosensitive layer made of a Ja-containing polymer is imagewise exposed and then developed. A method of forming a color image on a release layer by using an adhesive and then transferring this image to an arbitrary support (permanent support) using an adhesive is already well known (Japanese Patent Publication No. 46-15326, Kosho 49-
441), these methods have the advantage of being usable for various operations such as color proofing, overlay type, and subprint type.
When transferring, the process becomes complicated because it is necessary to use an adhesive every time, and it also has the disadvantage that it is difficult to maintain alignment accuracy when transferring each color.

As a method for eliminating the complexity of these processes, a method of transferring an image onto a permanent support by applying heat and pressure after forming the image is disclosed in JP-A-47-41830.

It is disclosed in publications such as JP-A-48-9337 and JP-A-51-5101. Especially JP-A-51-510
Publication No. 1 describes the provision of a heat-fusible polymer layer as an adhesive on a permanent support, and JP-A-47-41830 also describes the use of a permanent support such as art paper or coated paper. describes a method for directly transferring images.

However, these methods have various drawbacks. This means that the final image transferred onto the permanent support will be left-right inverted relative to the original, and when a thermofusible polymer is used as an adhesive, the transfer temperature will generally have to be adjusted due to its high melting point. This causes problems such as the dimensional stability of the support decreases due to the influence of heat and misalignment of transfer of each color. - On the other hand, when a heat-melting polymer with a low melting point is used as an adhesive, there are disadvantages such as adhesion occurring after the image is formed and the surface thereof being easily scratched.

As a method for improving the above-mentioned drawbacks, a method of transferring an image to a temporary image-receiving sheet before transferring the image to a permanent support is disclosed in Japanese Patent Application Laid-Open No. 59-971 filed by the applicant of the present invention.
It is described in Publication No. 40. That is, in this method, a temporary image-receiving sheet having an image-receiving layer made of a photopolymerizable material provided on a support is prepared, and before transferring each color image onto a permanent support, the temporary image-receiving sheet is The steps include transferring each color image thereon, then retransferring onto a permanent support, and then further over-exposure to harden the transferred photopolymerizable image-receiving layer.

The above temporary image receiving sheet (hereinafter simply referred to as image receiving sheet)
The image transfer method using the method is very effective in solving the above-mentioned problems. That is, by using this method, an erect image of the mask original can be obtained on the permanent support. Photopolymerizable image receiving sheet
The layer contains a photopolymerizable ethylenic polyfunctional supernatant.
Since the photopolymerizable image-receiving layer itself is soft and can be transferred at a low temperature, it can be easily cured by exposing the entire surface to light after transfer. That is, there are advantages in that no adhesion occurs after image transfer, and the final image has high scratch resistance.

In the image-receiving sheet used in the method described in JP-A-59-97140, the adhesive force between the photopolymerizable image-receiving layer (i.e., the photopolymerizable adhesive layer) and the support is lower than that of the unexposed layer. For this reason, after the image-receiving photopolymerizable adhesive layer has been transferred onto the final support, peeling off the support of the image-receiving sheet material before carrying out the exposure operation will cause the transferred image to disappear. Peeling streaks are likely to occur on the surface of the receiving photopolymerizable adhesive layer. For this reason, in the method described in JP-A-59-97140, after transferring the image-receiving photopolymerizable adhesive layer onto the final support, the entire surface is exposed to light.
A method is used in which the photopolymerizable adhesive layer is cured, and at the same time, the adhesive force between the photopolymerizable adhesive layer and the image-receiving sheet support is reduced, and the image-receiving sheet support is first removed.

Although the above-mentioned image transfer method is an effective method for obtaining a good final image, upon further detailed study by the present inventor, it was found that there are some areas where further improvement is desired as described below. .

The above image forming method (image transfer method) uses, as a photosensitive material, a photosensitive laminate in which a release layer made of an organic polymer, a coloring material layer, and a photosensitive layer are successively interlayered on a temporary support. can be done. In particular, high-quality transferred images can be obtained by using a photosensitive naphthoquinone diazide ester compound as the photosensitive material for the photosensitive layer. However, the absorption spectrum of the photosensitive naphthoquinone diazide ester has a base of 40. Since the naphthoquinone diazide ester compound extends over a region of Onm or more, there is a problem in that if this naphthoquinone diazide ester compound is left in the transfer resin layer containing the final image, it will adversely affect the color reproducibility of the final image. This problem arises because the naphthoquinone diazide ester compound decomposes simultaneously during the full-surface exposure carried out to cure the photopolymerizable image-receiving layer transferred from the image-receiving sheet onto the final support, especially when an independent decomposition operation is performed. It has been realized without any problems.

However, the surface of the final image is usually excessively glossy, so when the final image is used as a color proof for color proofing, the surface of the final image is generally Matting is being done. This matting is carried out using a method in which a suitable matte film is laid on the surface of the final image and the surface of the image is matted by heating and pressure.

In order to mattify the surface of the final image formed on the permanent support by the method described in JP-A-59-97140, a matte film is placed on the adhesive layer and the surface is heated and pressed. However, high heat and high pressure are required to matt the surface of the image under such conditions.

At this time, as the photosensitive material of the photosensitive layer of the photosensitive image transfer material, such as the above-mentioned naphthoquinone diazide photosensitive material,
If a photosensitive material that releases nitrogen gas upon photolysis is used, the naphthoquinone diazide decomposes and nitrogen gas is released when the photopolymerizable adhesive layer is cured by exposure to light. If the nitrogen gas is stored at the interface between the part and the adhesive layer and then subjected to high-temperature matting treatment, the interface may be deformed by the expansion of the nitrogen gas, degrading the quality of the image. That is, in a high-temperature treatment process such as matting, the stored nitrogen gas expands and forms bubbles, which deforms the surface of the receptor layer and reduces the gloss of the final image. This tendency is particularly noticeable in the shadow areas of halftone dots where bubbles cannot easily escape, and this phenomenon significantly reduces the commercial value of the final image as a color blue.

[Structure of the Invention f:&] The main object of the present invention is to provide a photosensitive transfer material that is particularly effective for obtaining a final image with excellent image quality.

The present invention relates to a photosensitive transfer material in which a layer made of an organic polymer, a coloring material layer, and a photosensitive layer containing a photosensitive naphthoquinone diazide ester are sequentially laminated on a previously known temporary support. As a result of our study, we found that by reducing the amount of naphthoquinone diazide esters used in photosensitive materials within a certain range, it is possible to effectively deform the final image due to nitrogen gas bubbling as described above without reducing sensitivity. Findings that can be prevented.

We have arrived at the present invention.

That is, the present invention provides a photosensitive transfer material in which a release layer made of an organic polymer, a coloring material layer, and a photosensitive layer containing a photosensitive naphthoquinone diazide ester are sequentially laminated on a temporary support, wherein the photosensitive layer is a naphthoquinone diazide ester.
