Abstract

PURPOSE:To permit transfer of a transfer image to a thin-gaged material or material of a kind which dislikes steps by transferring a photographic emulsion on the surface of photograph-mounting paper to a plastic sheet which is brought into pressurized contact therewith nd stripping the sheet from the mounting paper, then brining the plastic sheet having the transferred photographic emulison layer into pressurized contact with the material to be transferred to transfer said layer again in succession thereto. CONSTITUTION:The plastic sheet 6 made of polyester is brought into contact with the front side of the photograph 1 right after printing and is adhered thereof by the adhesiveness of the photograph 1 surface which is in a tacky state. After the sheet 6 is brought into complete pressurized contact with the photograph 1 in succession thereto, the sheet is stripped therefrom. The film layer 3 is stripped in the state of being adhered to the photograph-mounting paper 2 side at this time and only the photographic emulison layer 4 adheres to the sheet 6 side. The resulted sheet 6 and the layer 4 are imposed on the material 7 to be transferred, or after the adhesive agent is coated on the rear face of the layer 4, the sheet is stuck to the material 7 and only the sheet 6 is removed, by which the transfer is completed. The transfer of the emulsion layer to a desk, window glass, electrical products, etc., is thereby permitted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for transferring photographic images to various materials such as metal, wood, paper, synthetic resin, glass, and leather.

[Conventional technology]

Advances in printing and copying technology have led to the development of a wide variety of printing and copying methods, making it possible to perform simple and beautiful printing and copying.

For example, printing is applied to the surface of a sheet that has a pressure-sensitive adhesive surface, and the release paper that is in contact with the adhesive surface is peeled off and transferred. A simple transfer method in which the sheet is transferred using heat or pressure and then removed is known as a simple transfer method.

[Problem that the invention seeks to solve]

However, all of these transfer methods require that the image to be transferred be printed on a sheet or the like in advance, and can only be used in a so-called pre-crystallized form.

That is, in order to transfer a photograph taken with a normal camera, there is no way to directly attach it to the object to be transferred.

However, in this method, the thickness of the mount supporting the formed photographic emulsion is large, which gives an unnatural feeling and is often inappropriate.

[Means for solving problems]

Therefore, the inventor of the present invention has completed the method of the present invention as a result of intensive research in view of the above points, and its feature is that the photographic emulsion imaged on the surface of the photographic mount is transferred to a press-bonded plastic sheet. Then, the plastic sheet having the transferred photographic emulsion layer is pressed onto the object to be transferred and transferred again.

That is, the gist and starting point of the present invention is that a plastic sheet is used to peel off the photo mount, which accounts for most of the thickness of the photograph, and transfer it to a desired object. Photographs exhibit different properties due to structural differences, for example, differences between ordinary photographs and instant camera photographs, or differences due to the materials of constituent members. However, the present invention provides that whenever the photographic emulsion is fixed, it does not permeate the film layer between it and the photographic mount, and if it does, it is applied before the fixation. This is possible in either case.

The term "photo mount" refers to the part of the photograph that supports the photographic emulsion layer. A normal photograph consists of baryta paper, a film layer, and a photographic emulsion layer.
The term "photo mount" used in this book is one of these "
Refers to the part corresponding to "Baryta paper". Baryta paper is a paper with a baryta layer formed by applying a barium sulfate gelatin emulsion to the surface of a tough photographic base paper, rubbing it in, and drying it, so in the strict sense of the word, it is a multilayered structure. The film layer is also usually a multilayer structure and remains on the photomount side during transfer. In the case of photography using an instant camera, parts other than the photographic emulsion layer and film layer, such as the battery part, are also treated as a photographic mount, and the release sheet is treated as a member other than the photograph.

The "plastic sheet" is a sheet for separating the photographic emulsion layer from the photograph, and may be made of any material such as polyester or polyolefin.

The "transferred object" is an object to which the method of the present invention is applied, and its material and structure do not matter. For example, it refers to a desk or electrical appliance where a photographic image of a person is transferred onto the surface of the desk or electrical appliance.

Other items that can be used include everyday items such as bags and document binders, building materials such as wall doors, various plates, ceramics such as tableware, and furniture.

Specifically, the present invention includes various methods depending on whether the plastic sheet is left or not and whether the photographic emulsion is applied before or after fixing.

(1) A method in which the plastic sheet is not left behind and is carried out before the emulsion is fixed.

In this method, the plastic sheet does not need to be transparent, nor does it require adhesive on its backside. This is because the emulsion layer adheres to the sheet due to the adhesive force of the photographic emulsion before fixing. Furthermore, since the same applies to adhesion to the transferred object, no adhesive is required for that adhesion. Of course, it goes without saying that it may be applied to strengthen adhesion.

In this method, where no plastic sheet remains, the surface becomes a photographic emulsion, which is the actual photograph itself.

(2) A method in which the plastic sheet is not left behind and is carried out after the emulsion is fixed.

In this method, the plastic sheet does not need to be transparent as described above, but since the emulsion does not have adhesive strength, an adhesive is required on the back side of the plastic sheet. Furthermore, since it does not have adhesive strength to the object to be transferred, it is necessary to apply an adhesive to the back surface of the emulsion layer.

(3) A method in which the plastic sheet remains and is carried out before emulsion fixation.

This method requires that at least a portion of the sheet be transparent or translucent. This is to make the photo visible from above.

Since the emulsion has not yet been fixed, the adhesive is the same as in (1) above.

If the plastic sheet remains, the surface of the photograph can be protected, and when it is to be transferred to a practical object, it is effective because it can prevent the photograph from deteriorating in quality or discoloring.

(4) A method in which the plastic sheet remains and the emulsion is fixed.

The transparency of the sheet is the same as in (3) above. Also, since this is after fixing, the adhesive is basically the same as (2) above, but in this case, the sheet remains, so this sheet is larger than the photo and the protruding part If an adhesive has been applied to it, it can also be bonded with its adhesive strength.

Any of the above methods can be used, and the method may be selected as appropriate depending on the properties of the photographic film, the time required to process the photograph after it is taken, and whether a plastic sheet is necessary or not.

〔Example〕

Embodiments of the method of the present invention will be described in detail below based on the drawings.

FIGS. 1 to 5 are diagrams showing the method (1) described above (a method in which no plastic sheet remains and the emulsion is not fixed). FIG. 1 shows a photograph (11) immediately after printing, which is composed of a photographic mount (2), a film layer (3), and a photographic emulsion layer (4).

Immediately after printing, the photographic emulsion layer (4), which has formed an image but has not been fixed, is in a sticky state.
It is in a state where it is easy to peel off from the photo mount (2) etc.

Next, Figure 2 shows a polyester plastic sheet (6
) is about to be brought into contact with the front side of the plastic sheet (11). Although the plastic sheet (6) does not have any adhesive or the like applied to its surface, it is in a sticky state. Photo (1) Adhesion occurs due to the adhesiveness of the surface.

Next, Figure 3 shows the plastic sheet (6) as a photograph (1).
) is completely crimped and then peeled off. As mentioned above, the photographic emulsion layer (4) is adhered to the plastic sheet (6), and also to the photographic mount (2) and film layer (3), so when peeling it off, the adhesive strength is It will be separated into smaller parts. In this example, the photographic emulsion has not penetrated into the film layer (3) because it has not yet been fixed.
is peeled off while being adhered to the photo mount (2) side. Therefore, as shown in the figure, only the photographic emulsion layer (4) is adhered to the plastic sheet (6) side.

FIG. 4 shows the plastic sheet (6) and photographic emulsion layer (4) obtained in the process shown in FIG.
7). In the course of these operations, the photographic emulsion is gradually fixed, and its adhesive properties are therefore gradually reduced; therefore, if no adhesive is used for transfer, the operation must be carried out quickly. However, although not shown, if a method such as applying a separate adhesive to the back side of the photographic emulsion N (4) and then attaching it to the object to be transferred (7), strong adhesive force can be obtained and the photographic emulsion can be Transfer is possible regardless of whether the image is fixed or not.

And as shown in Figure 5, the plastic sheet (6)
Transfer is completed by removing only the (During the removal process, it is preferable that the photographic emulsion is in progress so that the photographic emulsion is not peeled off to the sheet (6) side.) Therefore, the transferred material (7)
The photographic image remaining on the surface is only the photographic emulsion layer (4), and its thickness is approximately 10 μm, which can be said to be ``not thick'' in general terms.

It can be used to store family photos, landscape photos, etc. on desks, window glass, etc.
If it is transferred to an electrical product, etc., it will become very unique.

In the embodiments described so far, the plastic sheet (6) is removed after the photographic emulsion layer (4) is transferred, but it may be left in place to enhance the protective effect of the transferred photographic image. (Fig. 6) In that case, the plastic sheet (6) must be at least partially transparent or translucent in order to make the photographic image clear. (It does not matter whether it is colored or colorless.) Furthermore, as is clear from the figure, it is also necessary to have an adhesive layer (8) on the side facing the transfer target (7). Therefore, it is not necessary that the photographic emulsion be in a state before it is fixed as in the embodiments shown up to FIG. ) After fixing, it is possible to carry out the process only if the film itself has a removable structure.

As a result of various experiments conducted by the present inventor, this property was found in some photographs for instant cameras.

〔Effect of the invention〕

As explained in detail above, the method of the present invention involves transferring the photographic emulsion imaged on the surface of a photographic mount to a press-bonded plastic sheet, peeling it from the mount, and then peeling the photographic emulsion from the mount, and subsequently applying the photographic emulsion to a plastic sheet having the transferred photographic emulsion layer. The method is characterized in that it is pressed onto the object to be transferred and then transferred again.
Because it is not a transfer of an existing printed matter, it is possible to obtain a unique transfer.Also, it is a transfer that uses the photographic emulsion layer of the original photograph itself, without using methods such as copying the original photograph. This makes it possible to transfer extremely beautiful photographic images, and the resulting transferred image has a very small thickness, making it suitable for transfer to thin objects or objects that do not like unevenness, especially for transfer. This effect is remarkable when the plastic sheet used is removed after transfer, and since there is no coating, the image has the same clarity as the original photographic image, etc. This is an extremely advanced invention.
