PURPOSE:To improve the character reading accuracy of an OCR without increasing the min. density of the ID booklet after a lamination treatment by specifying 400 to 900nm average reflectivity in the min. density part in a part of the superposed booklets to a specific value or above. CONSTITUTION:The ID booklet 1 consists of an ID page part 2 stated with personal information in addition with a portrait 4 and plural pages 9 which allows writing. At least a colored front material 10, a light reflecting base 11, an image recording layer 22 and a transparent film base 21 are superposed in this order to constitute a part of the booklet. The 400 to 900nm average reflectivity in the min. density part in a part of this booklet is specified to >=70%. The increase of the min. density on the image surface of the ID booklet 1 after the lamination treatment is suppressed in this way and the character reading accuracy of the OCR is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to an IDflO child, and more particularly to an rDllIl child readable by an OCR reader.

[Prior art] iDff [I, for example, a passport, student handbook, employee handbook, etc., must contain a photograph of the person's face, name, affiliation, personal code, etc. for identity verification in a part of the booklet. Various personal information is recorded.

Traditionally, verification of personal information has mostly relied solely on human eyes, and these IDf
In order to prevent unauthorized use of fl+, counterfeiting and tampering prevention measures were incorporated into the scale, and most of these measures could be immediately and visually identified by the human eye. Despite the many measures to prevent counterfeiting and falsification, there was no definitive method to prevent counterfeiting and falsification, so the unauthorized use of ID instruments still remains. do not have.

In particular, passports are required to be equipped with measures to prevent counterfeiting and alteration. Therefore, in addition to conventional visible identification methods, we have developed an fvIRP (Machine Readable Passport) screen that can read personal information using OC R (Obtical Character Recognition) characters and can use computers to confirm real-time identification. Gas is being admired.

IDIIO devices, such as MRP, which can mechanically read characters and confirm the identity of the person, are difficult to falsely report or alter, making them an excellent means of preventing unauthorized use. In other words, according to MRP, specific numbers and characters are derived according to specific rules from individual-based number 1 + Q data such as the individual's date of birth, date of issue, expiration date, etc., and the identity of the person can be verified by determining this. can be done immediately. Furthermore, since the identity verification process itself is performed by a machine rather than by human eyes, it can be performed quickly and accurately.

In this way, in MRP, personal data is read by a machine, so in order to avoid problems, misidentification, or delays in judgment time, particularly strict requirements are imposed on the characters that represent personal data. There is.

For example, MRP (7) part is ISO-7501
- stipulated in 1985.

In addition, many items such as character type, character size, character spacing, line spacing, character strokes, stains on non-text areas, and spectral reflection characteristics 11 of characters and non-text areas are specified.

Facial photographs, personal text information, or machine-readable portions are usually laminated onto a transparent plastic film.

By doing this, the recording surface becomes difficult to peel off, so vA
It is less likely to be falsified or tampered with, and is also useful for preventing contamination of text or protecting the image quality of facial photographs due to repeated use.

However, it is difficult to process such lamination 1! -=l-
Depending on the child, the character quality will be lower than before lamination. For example, variations in the line width of characters, variations in the minimum density (maximum depth 1''), variations in optical density due to uneven lamination of the laminate material, etc. occur.

Among these, this is a particularly big problem compared to the lowest level. That is, unless the minimum density is d/1 or less, it becomes impossible for the machine to read the characters itself.

In an ID curve in which an image recording body having an image recording layer with an image recorded on a transparent support is bonded to the back of the cover of a booklet, the final minimum density of R is equal to the optical density of the transparent support and the image It is affected by the minimum degree of dryness of the recording layer itself, the degree of coloring of the photo-reflective support bonded to the side to be joined to the recording material, the degree of coloring of the surface material, and the like. Therefore, it is preferable to select "white" as the surface material from the viewpoint of the degree of coloration, but depending on the user's preference and other requirements.
However, it cannot be limited to "white".

Furthermore, since the increase in the minimum density after lamination processing is much larger than the simple sum of the increases in each minimum density, it is necessary to suppress the increase in each minimum density J3 as much as possible. That is, the optical degree of the transparent support and the minimum depth of the image recording layer itself must be minimized.

[Problem to be solved by the invention] This invention was made to solve the above problems,
Purpose of the present invention [11] After lamination processing, suppress the increase in the minimum degree of image surface of the booklet, and
, improved viscosity (r r)) The purpose is to remove one foot of flll.

Another object of the present invention is to provide an IDml that maintains good OCR character reading accuracy without the minimum density being affected by the type of coloring of the covering material.

[1,000 Steps to Solve the Problems of the Present Invention]: The purpose of the description is to provide at least a colored surface material,
A light reflecting support, an image recording medium and a transparent film support are superimposed on this vessel to form part of the +IO device.
+ The average anti-DJ ratio of 400 to 900 nm in the lowest density part of a part of the stacked booklets is 70% or more.

Further, the above-mentioned object of the present invention is that the light-reflecting support in the ID fill has an average transmission density of 400 to 0.8 (at 100 nm or more), and that the light-reflecting support has a This is preferably achieved by having an average reflectance of 80% or more at ~900 nl.

Below, I will explain Motoaki in more detail.

The optically abraded support comprising the ID nl1 molecules of the present invention has an average transmission speed of 0.000 nm in the wavelength range of 400 to 900 nm.
It is preferable to use one having an average anti-S1 ratio of 8 or more and an average anti-S1 ratio of 80% or more. For example, paper or white film. As the paper, Japanese paper, high quality paper, art paper, cast coated paper, etc. can be used. Examples of the white film include white vinyl chloride film and white polyethylene terephthalate film. In the present invention, a paper support is particularly preferred from the viewpoint of ease of handling such as opening and closing of the booklet and measures against counterfeiting and alteration.

In the present invention, the spectral characteristics of the photoreflective support are particularly important. That is, the average transmission density of the light-reflecting support at 400 to 900 nm is preferably 0.8 or more, more preferably 0.9 or more. Below this, the spectral characteristics of the colored facing material often increase the minimum density on the laminate surface of the ID curve finally obtained. That is, when the average transmittance of the light-reflective support is 0.8 or more, the increase in the minimum permeability can be suppressed, and more preferably when it is 0.9 or more, the increase in the minimum permeability can be almost ignored. become.

On the other hand, the anti-copper properties of the light-reflecting support also have an important influence on the minimum depth of the finished ID matrix. Average transmission 8i! If the light absorption coefficient is 0.8 or more, and even 0.9 or more, the light absorption Q.1 support itself has a light absorption of 11'i Fil:
If it has the power, it will put an upper limit on the minimum concentration of i o nu children.

In order to suppress this rise in minimum energy to J3, go to 400~
The average reflectance of the light-reflecting support at onm is preferably 80% or more, and particularly preferably 85% or more.

The average transmittance W here is λmax = 450±
It represents the average value of optical transmission density at 20 nm, 550±20 nm, 1650±20 nm and 800±20 nm.

In addition, the average reflectance here (well, 5 sheets of the light-reflecting supports are stacked, and the back surface is 400 to 900 nIIl).
The reflectance at 400nlll to 900nm is set by superimposing black anti-feather bodies with an average reflectance of less than 5%.
The average value is shown when fi'1 is constant.

The average value of reflectance from 400 nm to 900 nm is 80
% or more, particularly preferably 85% or more, and it is particularly preferable that the lowest value of the repulsion rate is 70% or more.

In the above-mentioned light-reflecting support, the portion having the above-mentioned average transmittance rJ degree and average anti-copper ratio may be the entire laminate 1 of the image recording layer on which personal information is written, or a part thereof. good.

However, in order to always perform machine reading of characters with high accuracy, it is necessary to satisfy the above two spectral characteristics at least in the area where characters are written.

In order to satisfy the above two spectral characteristics, when using a paper support as a light reflecting support, it is necessary to use paper with a certain thickness or more, or to Various types of coated paper such as baryta paper, Ar11 paper, cast coated paper, etc., which are coated with a white pigment such as the following may be used.

In addition, when a white film support such as white vinyl chloride film or white polyethylene terephthalate film is used as the light-reflecting support, the thickness and particle size of the white pigment filled in the film or the thickness of the film may be changed. By doing so, it is possible to satisfy the above two spectral characteristics.

In wood research, a light-reflecting support is preferably used.Furthermore, the thickness of the paper support is 90L1.
It is particularly preferable to use various types of coats having a particle size of at least 100 μm, preferably at least 100 μm, and coated with the above-mentioned coloring pigment on the surface with a suitable binder.

In the present invention, a remarkable effect can be obtained when the reflectance of the lowest tide part (background part) in the finished curved state after lamination treatment is particularly high.

Therefore, in the present invention, in d3, at least t's
(The average reflectance in the 400 to 900 nm wavelength range of some parts of the booklet on which the JA mounted surface, light-reflecting support, image recording material, and transparent film are superimposed must be 70% or more. In addition, the degree of penetration of the lowest degree part of the laminate 1 film is 0.05 or less, preferably 0.0.
The effect of the present invention is particularly remarkable in children with ID+11 formed in J: 3 or less.

When a silver halide photographic material is used in the image recording layer, the effects of the present invention will be reduced if so-called fog or staining occurs significantly in the image recording layer. Furthermore, if the transparent film support is colored or if a treatment that causes further coloring (for example, the creation of a transparent hologram) is performed on the transparent film support, the effects of the present invention are likely to be reduced.

The IDfl[l child of the present invention will be explained below with reference to the drawings.

FIG. 1 represents the IDffO child of the present invention.

FIG. 1 shows an ID booklet 1 of the present invention, and the ID III booklet consists of an ID page group 2 in which personal information is written in addition to a facial photograph, and a booklet portion having a plurality of writable pages 9. The rD page part 2 is provided with a layer (not shown) that can be adhesively or thermally welded to a laminate material on a light reflecting support layer 11 (not shown) bonded to a facing material 10 (not shown). On top of this, there is an image recording layer in which a face photograph 4, personal information 5 such as name, address, date of birth, date of issue, etc., and machine-readable characters 7 are written.Laminating the laminate material 20. In the rD page section 2 created by the method, it is also possible to stamp a tally mark 6 on a part of the photo section, for example, as shown in FIG. 1, before or after lamination.

FIG. 2 is a cross-sectional view showing the state before the IDffll child in FIG. An adhesive layer or a heat-welding layer 12 that can be firmly bonded to the laminate material 20 is provided thereon.

On the other hand, an image recording layer 22 on which image information can be recorded is provided on a transparent film support 21.
contains all or part of personal information. When part of the personal information is written on the image recording layer, the remaining personal information can also be written on the adhesive layer or the heat-fusible layer 12. Further, if necessary, a face photograph or the like can be inserted between the image recording layer 22 and the adhesive layer or the heat-welding layer 12 as a single sheet so that only the face photograph part can be inserted between the sheets.

The laminate material 20, in which the transparent film support 21 and the image recording layer 22 have been temporarily suspended, is laminated at a predetermined position on the adhesive layer or heat-adhesive layer 12 of the ID page portion 2, and then heated as necessary. It is pressed and laminated, and the ID curve of the present invention is formed.

The material of the covering material 10 used in the present invention is not particularly limited, and may be made of synthetic leather, natural leather, etc., which are commonly used for notebooks, etc.
The most common material used is one containing polyvinyl chloride as the main component, mixed with a plasticizer and a coloring pigment. The color of the facing material is not particularly limited in the present invention, and any color such as black, red, green, and helmet can be used. Further, the side opposite to the laminated surface of the facing material 10 (the front cover side) may be subjected to treatments such as foil stamping with various letters, symbols, and patterns, such as gold foil or printing, as is usually done. can. The thickness of the facing material is usually 0.2-0.51, preferably 0.25-0.
It is 4mn+.

Mu Yunming's adhesive layer or heat welding I7J12 avoids the known adhesive or heat weldable resin disease.

Examples of the above-mentioned adhesives include Chemical Handbook Applied Edition Revised Third Edition (Maruzen Publishing, 1980), pp. 897-903, and Technical Series "Adhesion", supervised by Shozaburo Yamaguchi (Asakura Prison, 1981).
Those listed in the 20th to 38th truths are used. Adhesives preferably used in the present invention include hot melt adhesives (e.g. ethylene-vinyl acetate copolymer, polyethylene, polyamide, polyester resin, etc.)
, thermosetting VtU bamboo resin adhesives (e.g. vinyl acetate, chloroprene, acrylic emulsion, etc.), rubber adhesives (chloroprene rubber, etc.), thermosetting resin adhesives (urea resin, melamine resin, phenol, etc.) resin-based, epoxy resin-based, polyurethane resin-based, etc.), photocurable resin adhesives, natural product adhesives (geladine, starch, glue, etc.)
can be mentioned.

Furthermore, when the heat-weldable resin layer is bonded to the image-recording layer under heat and pressure, the binder of the image-recording layer is at least partially bonded to the binder of the image-recording layer without using another adhesive. J: Refers to the layer that is melted and bonded. however,
This layer may be omitted if the light-reflecting support 11 can be directly thermally welded to the image recording layer. The binder used in the heat welding layer is preferably a thermoplastic resin,
Any material may be used as long as it can be melted and mixed with the binders of both one-dimensional recording layers under heating. Preferably, the binder of the image recording layer and the binder of the hot-melt @ layer are both made of thermoplastic resin, and it is further preferable that at least a portion of the repeating position jii constituting each resin is chemically the same. In the present invention, polycarbonates, polyacrylates, polyesters, polyvinyl chlorides, etc. are preferably used as the thermoplastic resins used in the binder and heat-adhesive layer of the image recording layer, but polyvinyl chlorides are relatively preferred. Thermal welding can be carried out at low temperatures, which is particularly preferred. Lamination carried out under heat is carried out by internal heating or external heating. As the internal heating, ultrasonic waves, high frequency waves, microwaves, etc. are used, and ultrasonic waves or high frequency waves are particularly preferred because they can more easily melt the contact area with the laminate material having the image recording layer and temporarily suspend the bonding. Further, as external heating, a heat roller, infrared rays, heat seal, laser, etc. can be used.

Additionally, the temperature, pressure, and time during lamination can vary widely depending on the lamination method, but generally lamination 1 to
The temperature was 80 to 180℃, and the pressure was {yo1(,001 per 2
~100K(+, preferably 0.02-30K(I), and the lamination time is performed in one site for 0.01-30 seconds, preferably 0.1-10 seconds.

The lamination area may be all or part of the contact area between the image recording layer and the adhesive layer (or heat-adhesive layer) or the light-reflecting support. For example, it may be the entire area around the ID page section 2, it may be a part of the periphery, it may be the entire surface of the laminate 1 to material having an image recording layer, it may be a part thereof, but preferably it has an image recording layer. The entire surface of the laminate is coated with leaves.

Images can be recorded on the image recording layer 22 of the present invention by various methods. For example, recording characters by type printing, thermal transfer, etc., or characters using silver-halide color recording material,
Although facial photographs can be recorded, it is preferable to use a silver salt recording material, considering that a high-definition color image must be recorded at least in the facial photograph area. Preferred methods using a silver salt recording abrasive include, in addition to the color photography 71 method using wet processing, the so-called instant photography method using a color expansion transfer method, or the dry development method. ID 1111 child of the present invention [
Since particularly high measures to prevent counterfeiting and alteration are required,
It is particularly preferable to use a dry color heat development method in which the image recording layer is a dye image receiving layer made of a thermoplastic resin as a binder, and the image recording layer and the heat-fusible layer are irreversibly bonded. For details of this method, see, for example, Japanese Patent Application Laid-Open No. 1-114844, or the 17th Symposium of the Photographic Society of Japan - Considering a heat-developable silver salt recording system.
