Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to so-called ID cards and ID cards that prove personal identity, such as employee ID cards, student ID cards, driver's licenses, passports, etc. The present invention relates to a booklet (ID booklet) having a person's image, and also to a cart having a person's image, such as a business card with a photo, a credit card, a prepaid card, a postcard, a poster, a commuter pass with a photo, etc.

[Conventional technology]

For example, so-called ID cards and ID booklets (hereinafter referred to as rlDID carts) that prove an individual's identity, such as employee ID cards, student ID cards, driver's licenses, and passports, contain the person's photo, address, affiliation, and personal code. Various personal information such as Nα etc. for identifying the person is written or pasted.

Such ID cards, etc. perform their functions well under normal usage conditions, but if they are lost, the photo can be easily removed, and the mount and photo are generally not available. Because it is so easy to use, there are cases where photos are altered and altered, forged without going through the official channels, and misused, causing social problems.

For this reason, in the past, when creating an ID cart or the like, measures were taken, such as putting a stamp on the face photograph. However, in recent years, all information such as face photographs and text are recorded as image information on recording materials such as color photographic paper.
The image recording surface of this color photographic paper is covered with a laminating material that is difficult to obtain, for example, contains watermark,
It has been proposed that this be adhered by hot melt means or adhesive.

For example, JP-A-1-277837, JP-A-1-27835
No. 5 and No. 1-283190 disclose a technique of recording an image by a diffusion transfer method using a silver halide photosensitive material and then laminating the image surface to create an ID cart or the like. .

With these technologies, images can be formed without the need for any processing liquid, so it is easy to record images, and there are no particular restrictions on the environment in which ID cards, etc. are created, and processing liquid can be used. Workability is better than when using conventional silver halide photosensitive materials. Furthermore, compared to recording materials that do not use silver halide, such as thermal transfer methods, it has a higher resolution and allows detailed recording and processing, so it is superior in that it can effectively prevent forgery and alteration.

In addition, barcodes, optically readable symbols (OMR symbols), and characters (OCR characters) are recorded on ID cards, etc., and these recorded information is optically read by an optical reader to obtain the ID. It is also used to judge cards, etc. In such optical reading systems, systems that operate in various spectral regions are used, for example, as described in JIS C6253-1983.

[Invention or problem to be solved]

As described above, the diffusion transfer method using a silver halide photosensitive material is an excellent method for producing ID cards and the like in that it is easy to work with and can form images with high resolution.

However, this method has a problem in that unnecessary coloring (fogging) tends to occur in areas that have been processed by the diffusion transfer method or where no image is recorded, that is, white background areas. This coloring can be balanced to the extent that it does not pose a problem when visually identifying a human being, but it is possible to adjust the balance to the extent that it does not pose a problem when visually identifying a human being. When an image is recorded and read by an optical reading device, there is a problem in that the reading accuracy decreases.

In particular, if the fog density in the white background increases during storage of photosensitive materials or cards with images of people created over time, or changes due to density variations due to processing conditions or density unevenness during diffusion transfer, etc. However, there is a problem in that the reading accuracy of OCR characters and OMR symbols is significantly reduced.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a card containing a person's image that has a high-precision, high-resolution person's image, has a high reading accuracy of optically readable images such as OCR characters and OMR symbols, and is difficult to forge or alter. Our goal is to provide the following.

[Means to solve the problem]

In order to achieve the above object, the card with a person image of the present invention has at least a person image formed on a first sheet having an image-receiving layer layered on a support by a diffusion transfer method using a silver halide photosensitive material. and after recording an optically readable image on the first sheet and/or the second sheet, a second sheet is coated on the first sheet so that the image receiving layer is inside the first sheet and/or the second sheet.
A card with an image of a person formed by directly or indirectly joining and integrating sheets, in which the first sheet and the second sheet are integrated, at least in areas other than those processed by the diffusion transfer method. In the area of
It is characterized by recording an optically readable image.

It is characterized in that an optically readable image is recorded by printing with type and/or by melt-type thermal transfer.

Further, it is characterized in that a heat-developable photosensitive material is used as the silver halide photosensitive material.

Furthermore, it is important to note that substantially only images of people are formed by a diffusion transfer method using silver halide photosensitive materials, and that personal information images other than images of people are recorded by printing with movable type and/or melt-type thermal transfer. It is a feature.

The card with a person image of the present invention is formed by directly or indirectly joining and integrating the second sheet to the first sheet.

The first sheet has an image-receiving layer provided on a support, and image information including at least an image of a person is recorded on the image-receiving layer by a diffusion transfer method using a silver halide photosensitive material. At this time, for example, by making the size of the photosensitive material smaller than the first sheet, an area other than the area processed by the diffusion transfer method (hereinafter [non-diffusion transfer processing area J
) can be formed on the first sheet.

On the other hand, the cart containing an image of a person according to the present invention has a character image and/or a symbol image in which the person's image describes the person's name, gender, nationality, address, etc. as a personal information image. Further, the cart containing a person image of the present invention can be used, for example, with OCR characters or OM
It has an optically readable image such as an R symbol. These OCR characters, OMR symbols, etc. need to have high image quality, especially characters and symbols with less blurred edges and blur, in order to improve the reading accuracy of the optical reading device.

Further, from the viewpoint of compatibility with an optical reading device, it is preferable that the image exhibits spectral absorption not only to visible light but also to near-infrared light and is optically distinguishable.

However, it is difficult to meet the requirements for OCR characters, OMR symbols, etc. using the diffusion transfer method using silver halide color photosensitive materials using conventionally known methods. It is preferable to record by means other than diffusion transfer, and it is particularly preferable to record by printing by type and/or by melt-type thermal transfer.

The above OCR characters, OMR symbols, etc. may be recorded on either the first sheet or the second sheet. however,
When recording OCR characters, OMR symbols, etc. on the first sheet, it is necessary to record them in a non-diffusion transfer processing area on the image receiving layer. On the other hand, when recording OCR characters, ○MR symbols, etc. on the second sheet, record them on the side of the second sheet that faces and joins the first sheet, and also It is necessary to leave the image-receiving layer portion of the first sheet as a non-diffusion transfer treatment area without performing the diffusion transfer treatment.

An image formed by a diffusion transfer method using a silver halide photosensitive material may be recorded not only on the first sheet but also on the second sheet. In that case, the part where OCR characters, ○MR symbols, etc. are recorded on the sheet, the OCR characters, OM
The portion facing the R symbol etc. needs to be a non-diffusion transfer processing area.

The first sheet and the second sheet are joined and integrated so that the image-receiving layer of the first sheet is on the inside, that is, the image-receiving layer of the first sheet is directly or indirectly covered by the second sheet. There is.

The means for joining the first sort and the second sheet is not particularly limited. For example, the first sheet or the second sheet may have a structure in which a bonding layer is layered, and the second sheet may be directly bonded to the first sheet by the bonding layer. This bonding layer may be provided after recording the image, or may be provided before recording the image. Alternatively, for example, a joining sheet that is separate and independent from the first sheet and the second sheet may be interposed between the first sheet and the second sheet, and the first sheet and the second sheet are indirectly joined by this joining sheet. You may.

When bonding is performed using a bonding layer, it is preferable to provide a layer of hot-melt adhesive in advance and heat this to bond the two sheets together. In particular, there is a method of layering a hot-melt adhesive layer on a support, printing ○CR characters, ○MR symbols, etc. thereon, and then laminating two sheets and heating them to integrate them. preferable. Alternatively, after recording the image, a hot-melt adhesive layer or a pressure-sensitive adhesive sheet may be provided between the two sheets, and the two sheets may be bonded together.

If the image-receiving layer of the second sheet is composed of a thermoplastic resin, and the second sheet is composed of a thermoplastic resin layered on a support, the two sheets are joined and integrated by thermal welding. I can do it. This method is excellent in that it can effectively prevent forgery and alteration.

The supports of the first sheet and the second sheet may be reflective supports or transmissive supports. However, if a reflective support is used for one sheet, it is necessary to use a transmission support for the other sheet.

The card with a person image of the present invention is constructed as described above, and this card with an ID cart, ID
Used for booklets, etc. In order to use it as an ID booklet, it is preferable to bind the first sheet and/or the second sheet to a specific page of the booklet in advance.

[Effect]

Since the card with an image of a person according to the present invention is formed by a diffusion transfer method using a silver halide photosensitive material, the image of the person is clear.

Furthermore, when a heat-developable photosensitive material is used as the silver halide photosensitive material, workability is improved because no processing liquid or the like is required.

On the other hand, high-quality images can be obtained by recording optically readable images such as OCR characters and OMR symbols by printing with movable type and/or melt-type thermal transfer. Images that can be read optically can be obtained even with near-infrared light.

In addition, since the area where optically readable images such as OCR characters and OMR symbols are recorded is a non-diffusion transfer area, there is no reduction in reading accuracy due to fog, etc., and optical reading is possible. The device can read it with high precision.

In addition, the card with a person image of the present invention is made of two sheets joined together with the recording side of the person image and the optically readable image on the inside, so it is difficult to forge or alter. It is possible to sufficiently prevent the misuse of ID cards and the like.

In addition, by using the card with a person image of the present invention as an ID booklet, for example, it can be used as an OCR (optical character reader).
It is possible to create a machine reader pull passport (MRP) in which personal information can be mechanically read using an OMR (optical symbol reader) or the like. According to such MRP, by mechanically reading personal information using OCR etc., it is possible to carry out immigration control operations accurately and quickly, and to facilitate and speed up administrative processing. I can do it.

The support 10 constituting the first sheet 8 may be a reflective support or a transmission support.

However, when the support 10 of the first sheet 8 is a reflective support, the support 12 of the second sheet 9 is a transmission support.

Moreover, when the support 10 of the first sheet 8 is a transparent support, it is preferable that the support 12 of the second sheet 9 is a reflection support.

Supports 10 and 1 for the first sheet 8 and the second sheet 9
2 can be composed of, for example, a sheet of paper, synthetic paper, metal foil, plastic, etc.; a composite sheet made by laminating paper, plastic, etc. together; a composite sheet made by laminating one or both sides of paper with plastic; etc. .

Plastics constituting these supports 10 and 12 include polyethylene terephthalate (PET), polyethylene naphthalate (PEN), polycarbonate, acetyl cellulose, cellulose ester, polyvinyl acetal, polystyrene, polypropylene, polyvinyl chloride, nylon, polyethylene, etc. can be mentioned. In addition, these plastics contain white pigments,
For example, a material in which TlO2 or ZnO is dispersed may be used, or a material containing other coloring pigments or dyes may be used.

As reflective supports, paper and PE containing white pigments are used.
T is preferred, and the transparent support is preferably PET, polycarbonate, PEN, or polyethylene.

It is also possible to create an MRP by joining and integrating the first sheet 8 and the second sheet 9 to form a card with an image of a person, and then binding this card into a booklet l, but normally, One of the first sheet 8 and the second sheet 9,
Preferably, a sheet using a reflective support is bound into the booklet 1 in advance.

In FIG. 6, the second sheet 9 is bound to the booklet 1, but it may be separated from the booklet 1. In this case, since the image recorded on the second sheet 9 is configured to be observed through the transparent support, a horizontally reversed image is recorded on the second sheet 9.

The material of the cover J5 is not particularly limited, and materials such as synthetic leather, natural leather, plastic, paper, and the like that constitute ordinary notebooks can be used.

FIG. 7 shows a card 2 with a person image created as described above, in which a machine reading area 51 has an OCR character image 4.
, and also includes a background portion that serves as a reference for reflectance measurement. The size of the machine readable area 51 is determined, for example, by an optical reader. For example, IS
In the case of the MRP described in No. 0-7501, the machine readable area 51 means the area within about 23 orders of magnitude from the bottom edge.

Area processed by the diffusion transfer method using silver halide photosensitive material (hereinafter referred to as "diffusion transfer processing area") 52
does not occupy the entire surface of the image receiving layer 11. An optically readable image such as an OCR character and/or an OMR symbol is formed at least in an area other than the diffusion transfer processing area, that is, a non-diffusion transfer processing area. As shown in FIG. 7, it is preferable that the machine reading area 51 does not overlap the diffusion transfer processing area 52.

[The diffusion transfer processing area J is not only an area where a person image or a character image intentionally formed by the diffusion transfer method exists, but also at least an area where the diffusion transfer process is possible with the silver halide photosensitive material. It also includes areas where the white background is colored due to fogging.

In the example of FIG. 7, character images 5 other than OCR characters and graphic images 6 provided as needed can also be formed by the diffusion transfer method.

On the other hand, in the example shown in FIG. 8, only the human image 3 is formed by the diffusion transfer method. Therefore, coloring of the white background area due to diffusion transfer can be suppressed as much as possible. Also, in this case,
The character image 5 and the graphic image 6 can be recorded, for example, by the same method as recording OCR characters.

In order to effectively prevent forgery or alteration of the MRP, a colored pattern may be applied to the background of the character image 5 and the graphic image 6.

In particular, when an area including character images 5 and graphic images 6 is used as the diffusion transfer processing area 52 as shown in FIG. 7, it is preferable to apply a colored pattern to this background. It is possible to make the coloring of the parts less noticeable.

In the present invention, at least the human image 3 must be formed by a diffusion transfer method using a silver halide photosensitive material. Various methods have been known for this diffusion transfer method, and a method that can form a color image is particularly preferable.

In the present invention, it is necessary to remove a portion of the image receiving layer 11 layered on the first sheet 8 from the diffusion transfer processing area. For this purpose, for example, the size of the silver halide photosensitive material may be made smaller than that of the first sheet 8, and the diffusion transfer process may be performed.

In this embodiment, to record the OCR character image 4,
Type printing and/or fused thermal transfer are used. A typewriter or the like can be used for printing by type. Melt-type thermal transfer uses an ink sheet (recording material) containing a coloring material and a heat-soluble substance on a support.

Next, in order to confirm the effects of the present invention, an MRP of the present invention was created based on the above examples, and a reading test was conducted 20 times using an optical character reader H3-OCR manufactured by Judenko. However, the average orthodoxy rate was over 99%.

On the other hand, for comparison, an MRP was created in which an OCR character image was formed on the diffusion transfer processing area, and when the same reading test was performed 20 times, the normal continuation rate was 96% on average.

As is clear from this reading test, the card with an image of a person according to the present invention exhibits an excellent effect in that the reading accuracy by the optical reading device is higher than that of the comparative card with an image of a person.

Furthermore, the MR of the present invention created based on the above examples
After storing P and the above comparison MRP in a high temperature environment of 70°C and 65% relative humidity, a reading test was performed 20 times in the same manner as above, and the average success rate was However, in the case of the MRP of the present invention, it was as high as 99% or more, which was the same as before storage in a high temperature environment, whereas in the case of the MRP for comparison, it was 91%, which was a significant decrease. In addition, it was observed that yellow coloration occurred in the background of the OCR character image in the MRP for comparison.

As is clear from this reading test, the card with an image of a person according to the present invention has less change over time in the reading accuracy of the optical reader than the comparative card with an image of a person, and has high reading accuracy over a long period of time. It exhibits an excellent effect that can be obtained stably over a long period of time.

〔Effect of the invention〕

As explained above, according to the present invention, OCR characters,
Since unnecessary coloring does not occur in the background of an optically readable image such as an MR symbol, the reading accuracy of the optical reading device can be improved.

Further, since at least the image of a person is formed by a diffusion transfer method using a silver halide photosensitive material, an image with high precision and resolution can be obtained.

Furthermore, since a heat-developable photosensitive material is used as the silver halide photosensitive material, no processing liquid is required, making it easier to create cards with images of people, and making the work more efficient.

In particular, when the cart containing images of people of the present invention is implemented as an MRP, personal information can be read accurately using OCR, making it possible to efficiently carry out immigration control operations, etc. Become.
