Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a photographic print having a sub-image, and more specifically, a main image is formed by a silver halide photographic system and then a sub-image is formed by an electrophotographic system. How to make a photo print.

[0002]

2. Description of the Related Art There are many photographic print products in which illustration images such as characters and figures are attached to the main image surface of photographic paper.

As a method of forming an illustration image on such a photographic print, a sub-image original film consisting of the illustration image is prepared by a method such as computer typesetting and is printed on a photographic paper together with a photographic negative film as a main image. The method is usually adopted.

However, this method requires time and effort to prepare an illustration original film in advance, and moreover, the arrangement of the main image and the illustration sub-image of the photographic negative film is fixed, which limits the layout. Moreover, there is a complaint that the confirmation of the finish must be understood unless the photograph is printed.

In order to solve this problem, there has been proposed a method in which a main image is printed and developed on a photographic printing paper and then an illustration image is directly provided on the main image surface. For example, Japanese Patent Application 2-
No. 141019 proposes an apparatus for forming characters and images on a photographic print by a fusion type thermal transfer method. This is a simple method, but the gelatin layer forming the surface of the photographic paper absorbs water, and thus the image storability is poor.

Further, Japanese Patent Application No. 2-132944 has a thermal transfer image on a photographic paper having a silver halide photosensitive element, and a resin coat layer is laminated on the entire surface of the silver halide photosensitive element and the thermal transfer image layer. A photographic print and an image forming method thereof are disclosed. Although this improves the storability, the image is easily damaged when the resin layer is coated on the thermal transfer image.

In addition, a release agent, an antioxidant, a UV absorber, a light stabilizer, a filler (inorganic fine particles, organic resin particles), a pigment and an antistatic agent may be added to the surface layer.

A peeling agent is preferably contained in order to prevent fusion of the main image portion at the time of forming the sub-image. As such a peeling agent, silicone oil, silicone resin; paraffin wax, carnauba wax, polyethylene wax, Solid waxes such as amide wax and Teflon powder; fluorine-based and phosphoric acid ester-based surfactants; and polyolefin-based resins such as polyethylene resin and polypropylene resin. These resins and, if necessary, additives are dissolved or dispersed in a suitable solvent to prepare a surface layer coating solution, and a photographic paper on which a main image is formed by a known method such as gravure coating or roll coater coating. It is applied on the surface to form a surface layer.

Water is preferred as the solvent for the coating liquid because it has little adverse effect on the environment. When water is used, it is preferable to use a latex of the above resin. Further, if the coating solution is acidic, the main image is adversely affected such as discoloration, so that the pH of the coating solution is preferably 7.5 or more.

As another method for forming the surface layer, the surface layer can be formed by transferring the surface layer from the surface layer transfer sheet to the surface of the printing paper by heat and / or pressure.

The surface layer transfer sheet is a sheet in which a surface layer is provided on a support directly or through a release layer. As the support, a polyester film such as polyethylene terephthalate or polyethylene nephthalate, a polyimide film,
A resin film such as a polyamide film is used.

With respect to the resin for the surface layer and the additives to be added if necessary, the same materials as described in the above coating method can be mentioned.

Thermoplastic resins such as polystyrene resins, hydrocarbon resins, and cellulose resins; or silicone oil, silicone resins, fluorine-based surfactants, phosphate ester-based surfactants,
Examples of the release agent include polyolefin resins such as polyethylene resin and polypropylene resin.

When the surface layer is formed by the surface layer transfer method,
The surface layer may be formed on the entire surface of the photographic paper, or may be formed on a part of the surface of the photographic paper (for example, only the portion where the sub-image is formed or the peripheral portion of the portion where the sub-image is formed). The latter is preferable because the texture of the main image portion does not change.

Next, the protective layer will be described.

As the material of the protective layer, the surface protective resin or ultraviolet curable resin used for the above surface layer is used. As for the formation of the protective layer, as in the case of the surface layer, there is a forming method by applying, transferring, and additionally laminating.

The coating method is the same as the coating method for the surface layer.

The protective layer transfer sheet is one in which a protective layer is provided on a support directly or via a release layer, and the resin film mentioned as the support for the surface layer is used as the support.

With respect to the resin for the protective layer and the additives to be added if necessary, the same materials as described in the coating method can be mentioned.

In order to secure the peelability of the protective layer from the support, a release layer may be provided between the support and the protective layer,
Examples of the material forming the peeling layer include those mentioned for the surface layer.

When the protective layer is formed by the protective layer transfer method,
The protective layer can be formed on the entire surface of the photographic paper, but can also be formed on a part of the surface of the photographic paper (for example, only the portion where the sub-image is formed, or the peripheral portion of the portion where the sub-image is formed). The latter is preferable because the texture of the main image portion does not change. When a UV curable resin is used for the protective layer,
After forming the protective layer, ultraviolet rays are irradiated to cure the protective layer.

Regarding the protective layer, a laminate film having a heat-sensitive and / or pressure-sensitive adhesive layer provided on a transparent resin film is laminated on the surface of the photographic paper on which the main image and the sub-image are formed to form the protective layer, or After forming a mirror image of the sub-image by electrophotography on the heat-sensitive and / or pressure-sensitive adhesive layer of the laminate film, the laminate film having the mirror image is printed on the surface of the photographic paper so that the sub-image is at a predetermined position on the photographic paper It is also possible to form a protective layer by laminating on.
