Abstract

PURPOSE:To improve adhesiveness by removing at least a part or all of the peripheral border of the photographic emulsion layer of a photograph chemically or physically to disclose a photographic support, and directly bonding a protective sheet to the support to cover the photograph with a protective sheet. CONSTITUTION:A part or all of the peripheral border 3 of the emulsion alyer 2 of the photograph 1 is removed by a physical method, such as using a cutter or ruling machine, and a transparent protective sheet 4, sich as pllyester or polyvinyl chloride sheet, is overlaid on the photograph 1 and bonded with an adhesive 6. Since the emulsion layer 2 is removed and the disclosed support 5 is directly bonded to the transparent protective sheet 4 with the adhesive 6, adhesion is strong and the sheet is hardly peeled even if it is immersed in water.

Description

[Detailed Description of the Invention] (Industrial Application Field) The photographic product of the present invention is made by covering a photograph with a plastic film or other appropriate sheet, and is used for identification cards, driver's licenses, cards, etc. It is used.

(Prior Art) Identification cards, cards, and the like on which photographs are pasted have a disadvantage in that the surface of the photograph is easily scratched because the physical strength of the gelatin layer (emulsion layer) of the photograph is weak.

In order to improve this shortcoming and to prevent the face photo affixed to ID cards and cards from being replaced, conventional methods have been used to prevent ID cards and cards from being replaced, as shown in Figures M1 to 3. Transparent protective film B is pasted on top of photo A with adhesive 6.

In the photograph shown in FIG. 1, a transparent plastic sheet B having the same size as the photographic paper C is pasted onto the surface of a photograph A consisting of a photographic paper C and a photographic emulsion layer.

In Fig. 2, Mizuko's photograph A is laminated with heat-sealable transparent plastic sheets Ba and Bb from the front and back sides, and in this case, the transparent plastic sheet Ba to be laminated.

Using a larger size than photo A as Bb, as shown at the beginning of the same figure, attach the outer periphery of both seas (Ba) and Bb (Ea, E).
Photo B is glued together to prevent Photo A from being exposed to the outside.

The one shown in Fig. 3 is made by hollowing out the inside of a protective material F with the same thickness as that of photograph A, forming it into a frame shape, placing photograph A inside it, and transparent plastic sheets Ba and B are placed on both sides of the frame.
b is pasted together.

(Problems to be Solved by the Invention) The method shown in FIG. 1 is the easiest to manufacture, but it has the disadvantage that the adhesive between the photo A and the transparent plastic sheet H is poor and it easily peels off. In other words, the main component of the photosensitizer in photographic paper C or photographic film is gelatin, which has the property of absorbing water and swelling. This has the disadvantage that the gelatin layer (emulsion layer) on the outer periphery of the product absorbs water and peels off. In particular, the emulsion layer of a color photograph has a multilayer structure and is thick, so it has the disadvantage of being easily peeled off.

The one shown in Fig. 2 improves the viewing defect shown in Fig. 1 and is effective for protecting photo A, but since the sizes of the protection sheets (Ba, Bb) and photo A are different, As shown in FIG. 2, the thickness of the outer peripheral portions Ea and Eb is thinner than the other portions, and there is a drawback that a product with uniform thickness cannot be obtained. This not only has an unsightly appearance, but also has the problem of not being usable for products that require machines to read magnetic tapes, such as cash cards and credit cards.

The one shown in FIG. 3 has good adhesion and uniformity of thickness, but has the disadvantage that the manufacturing process is complicated, resulting in poor workability and increased cost.

(Means for Solving the Problems) An object of the present invention is to provide a photographic product that is coated with a transparent protective sheet that has good adhesiveness, has a uniform thickness, and has good adhesiveness. Our goal is to provide a method for manufacturing products.

Therefore, as shown in FIGS. 4 and 5, the photographic product of the present invention is manufactured by physically or chemically removing at least a portion or the entire outer circumference of the photographic emulsion layer 2 of the photograph 1 to form a photographic support. 5 is exposed, the protective sheet 4 is placed over the photograph 1 as shown in FIG. 6, and the protective sheet 4 is directly adhesively bonded to the exposed photographic support 5.

(Example 1) Photographs 1 in FIGS. 4 and 5 are produced by exposing a photographic material (film or photographic paper) using a support 5 such as polyester film or paper to light using a normal method. . The pattern to be exposed is arbitrary, such as a photograph of a person or a background pattern, and if necessary, exposure can be performed using a cathode ray tube connected to a computer or a laser beam.

A part or the entire circumference of the outer periphery 3 of the photographic emulsion layer 2 of this photograph 1 has been removed by a physical method such as a cutter or a ruling machine.

In the case shown in FIG. 6, a transparent protective sheet 4 made of polyester, vinyl chloride, or the like is polymerized and adhered with an adhesive 6 on top of the photo 1.

In the case shown in FIG. 7, a transparent protective sheet 4 is polymerized on both the front and back sides of a photograph 1, and then adhered with an adhesive 6.

The transparent protective sheet 4 may be preprinted with a predetermined pattern, characters, background pattern, or other appropriate items, and the transparent protective sheet 4 may be pasted so that the printed surface faces the photo l side.

If necessary, a magnetic recording layer 7 may be added to the transparent protective sheet 4 as shown in FIG.

The photograph 1 used in the present invention may be one in which the emulsion layer 2 is coated on the support 5, and is not limited to ordinary photographic paper or photographic film.

For example, a support 5 of milky white polyester or milky white vinyl chloride sheet having a magnetic recording layer on the entire surface of one side is provided,
A color photographic emulsion layer 2 may be coated on the other side.

As the support 5, it is also possible to use an opaque sheet of polypropylene, polyethylene, polycarbonate, etc. in addition to milky white polyester and milky white vinyl chloride.

As the adhesive used in the present invention, so-called hot-melt adhesives such as ethylene or propylene copolymers, reaction-curing adhesives such as epoxy, polyurethane, and acrylic adhesives, and other suitable adhesives can be used.

The method for manufacturing a photographic product described in claim 4 of the present invention is as follows.

A process of removing part or all of the portion of the photographic emulsion layer 2 of a photosensitive material such as photographic film or photographic paper that will become the outer periphery 3 in the final product, and exposing and exposing the necessary pattern to the photosensitive material.
This process consists of a step of developing and producing a photograph 1, and a step of laminating a transparent protective sheet 4 to the photograph 1.

If necessary, the transparent protective sheet 4 may be attached to the photograph 1 and then cut into a predetermined size.

(Example 2) As an example of the present invention, the one shown in FIG. 8 is a color film 10 having a support 5 made of milky white opaque plastic, and a portion that will become the outer periphery 3 in the final product is exposed solidly (first exposure). First, the following bleaching treatment is performed to remove the photographic emulsion layer 2 in the exposed areas.

For example, the bleaching process is performed as follows.

1. First development: Immersion in a regular black and white photographic developer 2. Stopping before development: Immersion in aqueous glacial acetic acid solution 3. Bleach: Immersion in a mixture of solutions A and B just before use (solution A) Cupric chloride 7g- 13g glacial acetic acid 30
cc ~ 70cc Water 850cc"l 100cc (B solution) 30% hydrogen peroxide solution 90cc-110cc 4, water washing If you lightly rub the photographic emulsion layer 2 with a brush or perform lt!i sonic cleaning, it will be developed in the first development. The emulsion layer in the exposed areas can be easily removed.

5. Clean. Soak in 5% sodium sulfite water. 6. Wash with water. 7.Drying All steps 1 to 7 are performed in the dark.

Through this bleaching process, a photographic film is obtained in which the photographic emulsion layer 2 in a portion corresponding to the outer periphery 1B3 of the final product has been removed.

This photographic film is subjected to a second exposure using patterns such as letters, tints, face photographs, etc. necessary for the final product, and then subjected to normal color development processing. - As shown in Figure 4, a photograph of the outer periphery 3 is obtained. A photograph 1 is obtained in which the emulsion layer 2 has been removed.

If a partial pattern exposure is performed on the portion corresponding to the outer peripheral portion 3 during the first exposure, the photographic emulsion layer 2 is partially removed according to the pattern as shown in FIG.

Thereafter, in exactly the same manner as in Example-1, a transparent protective sheet 4 is attached to the front or both sides of the photograph 1 using an adhesive 6. A photographic product is completed by cutting this into a predetermined size as necessary.

(Effects of the Invention) The photographic product described in claim 1 has the following various effects.

(1) Since the support 5 and the transparent protective sheet 4, which are exposed to the outside after the photographic emulsion layer 2 has been removed, are directly bonded with the adhesive 6, the bond is strong and does not peel off even when immersed in water. It's hard to do.

(2) When the photographic emulsion layer 2 is partially removed as shown in FIG. Protective sheet 4
Good adhesion can be obtained since the transparent protective sheet 4 is directly adhered to the transparent protective sheet 4, and thus the transparent protective sheet 4 is easily peeled off. In this case, it is possible to obtain a pattern that extends to the outer periphery. (3) The thickness of the photographic emulsion layer 2 is 0.005W~0.0
Since the thickness is about 2 mm, the change in thickness caused by removing the photographic emulsion layer 2 can be almost ignored. Moreover, since this reduced thickness is compensated for by the adhesive 6 that adheres the transparent protective sheet 4, the photographic product of the present invention has a uniform thickness all the way to the outer periphery and has good adhesive properties.

(4) As shown in Figure 7, attach the transparent protective sheet 4 to Photo 1.
It can also prevent curling of photographic products by adhering it to both sides.

(5) By changing the thickness of the transparent protective sheet 4 and the number of laminated sheets, the thickness of the photographic product can be adjusted as desired.

(6) If the necessary printing such as a predetermined pattern, text, ground pattern, etc. is applied to the transparent protective sheet 4 in advance, and the printed side is attached to the photo 1 side, the wear resistance of the printed text, pattern, etc. will be outstanding. In addition, it is also possible to prevent falsification of characters.

(7) By adding a magnetic recording layer 7 to the transparent protective sheet 4 as needed, a magnetic card with a face photo can be easily provided.

The manufacturing method described in claim 4 has the following various effects.

(1) This allows photographic emulsion W! 2, as shown in FIG. 8, a roll-shaped photographic material (film, photographic paper, or equivalent) 10 is used to remove the photographic emulsion layer 2, create a predetermined pattern, and create a transparent image; The process from bonding the protective sheet 4 to cutting it into a predetermined size can be performed in an integrated assembly line, which is very effective when processing a large amount at high speed.

(2) When creating ID cards, driver's licenses, etc., facial photos and various data such as the person's name and date of birth can be managed and controlled by a computer and exposed at the same time.
It becomes easy to match facial photos and personal data.

(3) As shown in FIG. 8, since data can be recorded on the magnetic recording layer 7 at the same time, no data mismatch occurs.

(4) The photographic emulsion layer 2 used in the present invention may be black and white, color,
Either negative-positive or positive-positive can be used as required.
