Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of making a photo ID card, and more particularly to a method of making an ID card of uniform thickness by inserting a thinned image forming layer between plastic sheets.

Traditional ID cards have an intermediate plastic sheet on the front and back sides.
The card name, date of issue, expiration date, signature, etc. are printed on it, and a transparent plastic sheet is placed on top of it, but in order to prevent misuse due to forgery, tampering, and loss, photo ID cards are used. is desired.

To date, various types of photo cards have been devised, but due to the complexity of the manufacturing process, price, appearance, etc., they have only become widespread in a small number of cases.

The photo ID card of the present invention can be manufactured by applying the conventional manufacturing method of ID cards without photos, and has a thin layer of less than 100μ between the intermediate layer of plastic for ID cards, which has an adhesive layer on the front and back, and the transparent sheet provided on the upper layer. This is a method of creating an ID card by inserting a layered image forming layer, heating and pressurizing it.

Furthermore, plastic ID cards are made in such a way that an embossing mark is applied on the card by an imprinter and is transferred onto a slip made of carbon paper or pressure-sensitive paper.

If a photograph is inserted into this plastic ID card and a cover is placed on it, and if any protrusions occur, the protrusions will be copied onto the slip by the imprinter, staining the slip.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned drawbacks and to provide a method for producing a photo-embedded plastic ID card having a flat surface without protrusions.

It is an object of the present invention to provide, in place between the transparent plastic sheet and the intermediate plastic sheet, a total thickness of 10 mm.
Production of a photo card characterized in that a developed photographic film or photographic paper of 0μ or less is pasted with adhesive and then heated and pressurized from the outside to produce a plastic ID card with a uniform thickness. This is accomplished by a method.

Hereinafter, embodiments of the method of the present invention will be described based on the attached drawings.

In FIG. 1, a photo card 1 produced by the method of the present invention is as follows:
Two opaque intermediate plastic sheets 2.3 are glued together to form a kind of core material, with a transparent plastic sheet 4 on the lower surface of the core material and another transparent plastic sheet on the upper surface of the core material. Further, developed photographic film or photographic paper 6 is temporarily attached to the sheet 5 at a predetermined position between the upper surface of the core material and the other transparent plastic sheet 5 with adhesive, and heated and heated from the outside. It was obtained by pressing.

For the intermediate plastic sheets 2 and 3 and the transparent plastic sheets 4 and 5, general-purpose polymers such as polyvinyl chloride, polystyrene, polyethylene, cellulose acetate, polyester, and nylon can be used. Vinyl chloride is suitable for insertion to make the overall thickness of the card more uniform and for embossing the card.

Regarding the film or photographic paper 6, it is difficult to create a card with a thickness of approximately 100μ or less, and if the thickness is more than 100μ, air bubbles will be generated around the film or photographic paper 6, which is not desirable in terms of product. There is.

There is no problem if the photographic paper containing the support has a thickness of 100μ or less, but most of today's photographs have a thickness of 100μ or more.

In the present invention, an ID card having a uniform thickness is produced by using color photographic paper or black and white photographic paper which is not mechanically polished and is made into a thin layer of 100 μm or less.

Another method for color photographic paper and black and white photographic paper is to immerse it in a chemical solution and peel the emulsion layer from the support layer.

For this method, please refer to ARTISTSHACK p I
Photique etc. made by nc-(N-J-USA) can be used.

For color films and black and white films, use an image forming layer including a support of 100 μm or less in advance, or if the image forming layer is 100 μm or more, use a photographic material in which the silver halide emulsion layer can be peeled off from the support. Peel the layer from the plastic film support,
Used for ID cards.

Further, the intermediate plastic sheets 2 and 3 are usually selected to be opaque, white, and hard, but they may be colored differently depending on the purpose.

Furthermore, the intermediate plastic sheet can be made into a single sheet as shown in FIG. 2 depending on conditions such as rigidity and thermal strain.

As described above, the method for producing a photo ID card according to the present invention allows the conventional ID card production method to be used by making the image forming layer thinner, and allows the card user to use ordinary photographic paper,
If you send us a photo of the film, we can apply it as a thin layer.

Moreover, the manufacturing method is easy, and photo ID cards with uniform thickness can be created.

Next, examples will be shown and the present invention will be further explained in detail.

Example 1 A predetermined print was applied to one side of two 250 μ thick opaque white hard vinyl chloride sheets (made by Cylindrical Plastic KK), and a portion of the front sheet was left blank for inserting a photo. Indulge.

The other card is printed to become the back side of the ID card.

Next, prepare two transparent hard vinyl chloride sheets (manufactured by Tsutsunaka Plastics KK) with a thickness of 100μ, and
00μ transparent hard vinyl chloride, “VL3” as adhesive
0" (manufactured by Gisuke Konishi Shoten) on both sides with 30μ of opaque white hard vinyl chloride, which is printed on the back of the ID card, and stacked with the printed side facing down. On top of that, 250μ thick opaque white hard vinyl chloride coated with 30μ of "VL30" on both sides and printed to become the surface of the ID card, is layered with the printed side facing up, and then placed on top of it in the designated areas. , For a facial photograph, place a 250μ layer of color photographic paper on the rotating part of a #lOO sandpaper grinder, press the back side of the photograph, press it lightly from the top and move it to a thin layer of 60μ, and further increase the thickness. A uniform ID card with a thickness of 820 μm was produced by stacking transparent vinyl chloride sheets with a thickness of 100 μm and heating and pressurizing them at 100 to 120° C.

The ID card of this embodiment can also be embossed.

Example 2 Similar to Example 1, opaque white hard vinyl chloride 2 with a thickness of 250μ was printed in a predetermined manner and coated with adhesive on both sides.
For the photograph to be inserted, a 30μ emulsion layer was peeled off from a strip-type lith film (manufactured by Fuji Photo Film KK), from which the emulsion layer of a silver halide photographic film can be peeled off from the support. Similarly, superimpose
By heating and pressurizing, an 820μ ID card was obtained.

Embossing is possible in this embodiment as in the first embodiment.

Example 3 A black and white Polaroid photograph was processed using Photique liquid (ARTIS).
The emulsion layer having a thickness of 20 μm was peeled off, and a photo ID card was prepared in the same manner as in Example 1.
