Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ID card that can be manufactured quickly and inexpensively. The present invention also includes a method of manufacturing the ID card.

It is desirable that ID cards, including ID cards, membership cards, cash cards, credit cards, etc., be provided with a photograph of the user's face so that the person using the card can easily identify himself or herself.

However, it is troublesome to paste each photo on the card mount, which not only hinders rapid mass production and increases costs, but also causes problems during mechanical processing for cards with a magnetic recording layer. It's easy to do.

So I took a picture of the face, but the ID is uniform in thickness.
Attempts have been made to create cards, and several techniques have been put into practice. For example, diffusion transfer or the use of a card mount coated entirely with a diazo sensitizer. The applicant has also devised and disclosed a card in which an image is formed by engraving minute and independent recesses of different sizes (Utility Model Publication No. 5]-24331).

However, all of these are monochrome and cannot fulfill the desire to express them in color. With the intention of providing a card that can be displayed with a color photograph and has a uniform thickness, a support base having a recess of a specific size and depth and an intermediate plate having a corresponding part of -1 pacha are prepared. Therefore, a method was proposed in which records were laminated together with photographs (Utility Model Publication No. 82700/1983), but this was not suitable for mass production and was expensive.

The purpose of the present invention is to improve the various points not met by the conventional techniques, and to provide an ID card that has a high-quality color image and does not hinder the use of the magnetic recording layer, and a method for manufacturing the same. .

To explain with reference to the drawings, as shown in FIG. 1 as a plan view and as shown in FIG. A protective coating 4 is applied to the surface layer 3, on which a face photograph 31 and necessary information 32, such as the owner's address and name, membership number, and expiration date, are written on the surface. It is something. For many applications, it is preferable to provide a magnetic recording layer 5 on the back side, as shown.

The method for manufacturing the ID card described above is to first prepare a photographic paper made of plastic film and coated with a color photosensitive emulsion on the surface, then print a photograph of the face and other necessary information such as those mentioned above onto this color photosensitive emulsion, develop it, and then After fixing, a heat-retaining coating is applied to the surface and the film is cut to a predetermined size.

Providing the magnetic recording layer on the back surface may be performed in any of the steps described above.

The plastic film used as the base material is used to provide water resistance and durability, and there are no particular restrictions on the material, but from the standpoint of achieving a balance between rigidity and flexibility and ensuring toughness, polyester is preferred. good. Based on practical experience, a film of about 175 μm thick made of polyester mixed with titanium white is optimal.

Color photosensitive emulsions contain gelatin as a binder and are hydrophilic, and are developed in an aqueous system. To ensure adhesion to the base film of the emulsion layer, the base material must be surface-treated to give it some hydrophilic properties, or it must be coated with a material such as polyester prior to coating the emulsion layer. However, it is recommended that there be an intermediate layer of material that adheres to both hydrophobic materials and fresh water-based materials such as gelatin. Depending on the combination of substrate and emulsion used, it will be possible, if necessary, by some experimentation, to find a suitable interlayer material.

The magnetic recording layer provided on the back surface may be formed by applying commonly used iron oxide powder using a suitable binder, and the technique is known. You can choose between a full coat or a partial (striped) coat.

In a typical manufacturing process, it may be convenient to first apply this magnetic recording layer to one side of a plastic film substrate, and then apply the color emulsion to the opposite side.

The photograph of the face on the surface of the card and the recording of necessary information can be carried out by subjecting the cart mount, which is a photographic paper produced in the manner described above, to printing and development. Special negatives are prepared for fixed items across a large number of cards, such as the letters on the membership card J and the association mark, and for items that are different from each other, such as face photos and name number 1, they are printed separately for each winter crop. All one has to do is make a negative and print the two one on top of the other. This process can be automated, and one skilled in the art would be able to easily design and construct a composite printer device for use therein.

Once developed, fixed and dried, a protective coating is applied to the surface of the card. This makes the card durable and helps prevent tampering. The protective coating is preferably applied by applying a thin film of plastic material, such as polyvinyl chloride, polyester, polypropylene, by heat sealing with or without adhesive.

Alternatively, a suitable paint may be used.
In that case, as shown in Examples below, a two-layer structure of an anchor coat and an overcoat can also be adopted.

In other words, at the time of application, a material is selected that is hydrophilic and can penetrate into the emulsion layer, and is later cured by reactions such as polymerization or condensation, and the cured material has good adhesion to the overcoat layer. This is followed by an overcoat. In this way, the best protective coating can be firmly established. For example, some polyurethane resins with crosslinking properties are suitable for this purpose. There is something suitable.

Considering that it is advantageous to carry out the above-mentioned processes starting from the film base material and using a long and wide object, it is convenient to carry out the cutting at the end, for example, by punching. Dew. However, it is also possible to cut the photographic paper to the size of a card and perform the subsequent printing steps on the resulting mount, and such an embodiment is also included in the present invention.

As explained above, since the ID card of the present invention uses a color photograph over the entire surface, not only the facial photograph part is in color, making it easy to identify the person, but also other information on the card surface. It is possible to record clearly in a desired color, and the background color and background pattern can be selected arbitrarily. As already mentioned, the facial photograph portion is not thick and is suitable for automatic processing with a magnetic device.

Still, the ID card manufacturing method of the present invention is particularly effective when a large number of cards are to be manufactured at once, and the cards can be manufactured quickly and at low cost.

Therefore, cards can now be easily adopted in fields that have been previously held back due to the time and cost involved in creating cards.

EXAMPLE A titanium white mixed polyester film having a thickness of 175 μm was used as a base material, a magnetic recording layer was provided on the back side by a direct coating method, and then a color photosensitive emulsion layer was formed on the front side.

After filling in the necessary information for printing, developing, and fixing, an anchor coat with the following composition was applied on the emulsion layer. The coating amount is 32/-.
