Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is applicable to employee ID cards, student ID cards, driver's licenses, passports (
The present invention relates to a method for producing a so-called ID card and a booklet containing an ID card (ID booklet) used to prove an individual's identity, such as a passport.

The present invention also relates to a method for producing a card having a person image, such as a business card with a photo, a credit card, a prepaid card, a post card, a poster, a commuter pass with a photo, and the like.

[Conventional technology]

For example, so-called ID cards and ID booklets (hereinafter abbreviated as rTDID cards) are used to prove personal identity, such as employee ID cards, student ID cards, driver's licenses, and passport photos.

) is written or pasted with various personal information for identifying the person, such as the person's face photo, address, affiliation, personal code Nα, etc.

Do these ID cards, etc. perform their functions adequately under normal use conditions?For example, if they are lost, the photo can be easily destroyed, and the mount and photo are generally easy to obtain. As a result, there are cases where photographs are altered by pasting them, or forged or used without going through the official channels, causing social problems.

For this reason, in the past, when producing ID cards and the like, measures were taken, such as putting a stamp on the photograph of the person's face. However, in recent years, all information such as facial photographs and text is 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 by adhesive.

For example, JP-A No. 1-277837, JP-A No. 1-27835
No. 5 and No. 1-283190 disclose a technique in which an image is recorded by a diffusion transfer method using a silver halide photosensitive material, and then this image surface is laminated with a material to produce an ID card or the like. .

With these techniques, images can be formed without the need for any particular processing liquid, so it is easy to record images, and there are no particular restrictions on the environment in which ID cards or the like are produced; Workability is better than when using conventional silver halide photosensitive materials which require liquid. Furthermore, compared to recording materials that do not use silver halide, such as thermal transfer methods, the resolution is higher and finer recording and processing is possible, so it is superior in that it can effectively prevent forgery and alteration. .

In addition, optically readable symbols (OMR symbols), characters (OCR characters), barcodes, etc. are recorded on ID cards, etc., and these recorded information is optically read by an optical reader. It is also used to determine ID cards and the like.

In such an optical reading method, for example, J
Those operating in various spectral regions as described in IS C6253-1983 are used.

[Problem to be solved by the invention]

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 areas that do not require image transfer by the diffusion transfer method, that is, white background areas, are likely to be colored due to unnecessary fog. This coloring due to fogging not only impairs the aesthetic appearance of the manufactured cards with images of people, but also records optically readable images such as OCR characters, OMR symbols, and barcodes on the white background, which can be optically read. When reading with a reading device, there is a problem 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 produced 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, OMR symbols, bar codes, etc. is significantly reduced.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to prevent coloring from occurring in parts that do not require image transfer by the diffusion transfer method, to produce a car 1- with a portrait image of good quality in appearance, and to provide OCR. It is an object of the present invention to provide a manufacturing method capable of manufacturing a card containing a person image with high accuracy in reading optically readable images such as characters, ○MR symbols, bar codes, etc.

[Means to solve the problem]

The present invention has been made to achieve the above object. That is, on a first notebook in which an image-receiving layer is layered on a support, a small image of a person is formed on the first sheet and/or the second sheet by a diffusion transfer method using a silver halide photosensitive material. After recording an optically readable image thereon, a car F with a person image is produced by directly or indirectly joining and integrating the second sheet to the first sheet so that the image-receiving layer is on the inside. In this method, the above object is achieved by partially inhibiting development and/or transfer during image formation by the diffusion transfer method to provide a portion where no image is substantially formed.

In addition, the second sheet and the second sheet are the cards with character images.
Forming an image by a diffusion transfer method such that at least part or all of an optically readable image is present in an area where the image is not substantially formed by the diffusion transfer method in the integrated state of the sheet. It can be produced by partially inhibiting development and/or transfer during the process.

Furthermore, when performing image formation by the diffusion transfer method, a sheet body is sandwiched between the silver halide photosensitive material and the first sheet, and this sheet body partially inhibits development and/or transfer, thereby producing images of people. It is a preferred embodiment of the present invention to produce a card containing a card.

Furthermore, when forming an image by the diffusion transfer method, the image of the person is formed by inhibiting development and/or transfer so that only the image of the person is substantially formed and other parts are not substantially formed. You can also create cards.

Further, it is preferable to use a heat-developable photosensitive material as the silver halide photosensitive material used in the diffusion transfer method.

In image formation by a diffusion transfer method using a silver halide photosensitive material, at least a photosensitive material and an image receiving material are used. Both may be supplied separately or may be supplied in an integrated manner.

Image information, including at least an image of a person, is recorded on a photosensitive material 2 by exposure, and through a development and transfer process, the image is recorded on an image receiving material 2.

However, as described above, in the past, when forming a diffusion transfer image, there was a problem in that portions that did not require image transfer, such as white background portions, were also colored due to so-called fog. The coloring of the white background part due to this fog not only deteriorates the appearance of the completed card with a person image, but also the above-mentioned OCR characters, OM
When recording an R symbol, a bar code, or the like, there is a risk that the optical reading accuracy may be lowered.

However, in the present invention, development and/or image transfer in areas that do not require image formation by the diffusion transfer method is inhibited. Image transfer in areas that do not require image formation by the diffusion transfer method often results in fog transfer.

In order to inhibit development and/or image transfer of areas that do not require image formation by the diffusion transfer method, a development inhibitor and/or a transfer inhibitor is used.

When the inhibitor is a solid, it is possible to inhibit image transfer by, for example, inserting a sheet (inhibitor) between the photosensitive material and the image-receiving material. It is necessary to ensure that there are no transfer-inhibiting substances in the areas where image transfer is required, so when inserting a sheet as described above, holes must be made in the areas where image transfer is required. Measures such as leaving the door open may be used.

If the inhibitor is a liquid, it is possible to inhibit development and/or image transfer by, for example, applying the inhibitor onto the light-sensitive and/or image-receiving material. When applying a liquid inhibitor, it is necessary to avoid applying the inhibitor to areas where image transfer is required. For this purpose, in addition to known coating methods, known printing methods can also be used.

In order to provide a portion where a diffusion transfer image will not be formed, for example, when forming a person image by the diffusion transfer method, the size of the photosensitive material is made smaller than the image receiving material, and a part of the image receiving material is processed by the diffusion transfer method. It is also possible to make it happen. However, in this method, since the size of the photosensitive material is limited, it is difficult to separate the photosensitive material from the image-receiving material. Further, there is a problem in that the surface of the image-receiving material in the portion where the photosensitive material is not stacked is easily stained. This problem becomes particularly noticeable when a heat-developable photosensitive material is used.

However, according to the method of the present invention, the size of the photosensitive material is basically not restricted in any way and can be freely selected, so a shape that facilitates peeling from the image-receiving material can be selected. .

Furthermore, the shapes of the portions to be imaged and the portions not to be imaged by the diffusion transfer method can be freely set.

Furthermore, contamination of the image-receiving material can be prevented.

[Effect]

Since the card with an image of a person produced by the method of 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.

According to the method of the present invention, it is possible to obtain a card containing a person's image without coloring due to unnecessary fogging on the white background part, so it has an excellent appearance.
When optically readable images such as symbols and barcodes are recorded, there is no unnecessary coloration due to fogging, etc., so there is no reduction in reading accuracy and it can be read with high precision by an optical reading device. .

In addition, since the card with a person image produced by the method 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, it cannot be counterfeited or tampered with. It is difficult to do so, and misuse of the rD card etc. can be sufficiently prevented.

Furthermore, by using a card containing a person image produced by the method of the present invention as, for example, an ID booklet, it is possible to perform OCR processing.
Machine reader pull passport 1 (MR
P) etc. can be produced. 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.

When an image is exposed to light on a silver halide photosensitive material, the image is transferred to an image-receiving layer after or simultaneously with development.

In this embodiment, as shown in FIG.
The image receiving layer 11 is layered on the support IO of the sheet 1-8.
is composed of a substance capable of blocking the image forming substance emitted from the silver halide photosensitive material, and is specifically selected in consideration of compatibility with the silver halide photosensitive material. For example, when a hydrophilic dye is released as an image-forming substance from a silver halide photosensitive material, the image-receiving layer 11 is preferably formed of a hydrophilic binder such as ceratin. Further, the image receiving layer 11 may contain a dye mordant or the like as a dye fixing agent. When a hydrophobic dye is released from the silver halide photosensitive material, the image-receiving layer 11 is preferably formed from a hydrophobic polymer such as polycarbonate, polyester, polyvinyl chloride, or the like.

As will be described later, thermal welding of thermoplastic resins may be used to join the first seam 1-8 and the second seam 1-9 (see FIG. 5). For this purpose, at least the image receiving layer 1
1 needs to be formed using thermoplastic resin. Therefore, it is preferable to employ a system in which a hydrophobic dye is transferred to a hydrophobic thermoplastic resin such as vinyl chloride, as described in JP-A-1-193844 and JP-A-274130.

As shown in FIG. 2, the photosensitive material 31 and the first sheet 8 are stacked with the photosensitive layer 33 and image-receiving layer 11 in close contact with each other, and then diffusion transfer is performed to form a dye image on the image-receiving layer 11. or formed. Develop only the roughened photosensitive material 31,
After forming the diffusible dye, the photosensitive material 31 and the first sheet (image receiving material) 8 may be stacked to perform diffusion transfer.

Furthermore, development and transfer can be performed simultaneously with both stacked. Further, after applying a transfer aid on the photosensitive layer 33 or the image receiving layer 11, the two may be overlapped to perform diffusion transfer.

As mentioned above, in the present invention, it is preferable to use a heat-developable color photosensitive material as the silver halide photosensitive material used in the diffusion transfer method.

In the present invention, development and/or transfer is partially inhibited to provide a portion where image formation by diffusion transfer is not substantially performed.

FIGS. 3(a) and 3(b) are explanatory diagrams showing an example of a method for providing a portion where image formation is not performed by diffusion transfer, and in this example, a photosensitive material 3I and a first no.
Diffusion transfer is performed with sheets 1 to 8 (hereinafter referred to as "mask sheets") for inhibiting transfer being sandwiched between them. The mask sheet 4I is partially provided with holes, and diffusion transfer is performed in these portions and an image is formed on the first sheet 8, or transfer is inhibited in other portions. In order to ensure that images are formed in the holes, the mask sheet 41 needs to be as thin as possible. Its thickness is preferably 50 μm or less, more preferably 2 μm or less.
It is 5 μm or less. Particularly preferably, the thickness is 15 μm or less.

Although the material of the mask sheet 41 is not particularly limited, it is preferable to select a material that will not be destroyed during the diffusion transfer process. For example, when a heat-developable photosensitive material is used, it is preferable that the material does not melt at the temperature at which heat development is performed.

Preferred materials for the mask sheet 41 include paper, synthetic resin film, metal foil, and cloth.

As the paper, paraffin paper, parchment paper, thin paper, chemical fiber paper, metal foil paper, metallized paper, synthetic paper, art paper, coated paper, release paper, l-lacing paper, medicine wrapping paper, etc. can be used.

As the metal boil, it is preferable to use aluminum foil.

Examples of synthetic resin films include polyethylene terephthalate (PET), polyethylene naphthalate (PEN),
Polycarbonate, cellulose acetate, cellulose ester, polyhinyl acetal, polystyrene, polyethylene, polypropylene, polyvinyl chloride, nylon, etc. can be used.

Is it possible to store the mask sheet 41 separately from the photosensitive material 31 and the first sheet 8 and insert it between them when performing diffusion transfer?
It is a preferable method to store the photosensitive material 31 in a state in which it is attached to the sheet 8. In particular, it is preferable to apply the old mask sheet on the first sheet 8 in advance and peel off the photosensitive material 31 after diffusion transfer. In this case, mask sheet 41 or photosensitive material 31
A preferable form is that it is attached to and then peeled off.

Another method for providing a portion where a diffusion transfer image is not formed includes a method of coating a development inhibiting substance and/or a transfer inhibiting substance on the image receiving layer 11 and/or the photosensitive layer 33. FIG. 4 shows a transfer inhibiting substance 42 on the image receiving layer 11.
This shows an example of a case where the

When a heat-developable photosensitive material is used as the photosensitive material and image formation is performed by diffusing the dye to the first sheet 8 by thermal diffusion, a non-thermoplastic resin or a resin with a high glass transition temperature is used as the image-receiving layer 11. Transfer can also be inhibited by coating on the photosensitive layer 33.

For such partial coating of resin, known coating methods,
You can use the printing method.

In a system in which a hydrophilic dye is transferred to a hydrophilic binder such as seratin, as described in each publication of No. 5, the image receiving layer 11 on the first sheet 8 is made of a hydrophilic resin,
A hydrophobic resin can be coated as a transfer inhibitor.

In addition, the developability of silver halide or the diffusivity of dyes
For example, if the pH changes, application of an acid or base solution can inhibit development or transfer.

Another means for inhibiting development is to apply a solution of a so-called inhibitor compound, such as a compound having a mercapto group or a nitrogen-containing heterocyclic compound.

Furthermore, as another means, it is also possible to roughen or emboss the surface of the image-receiving layer 11 and/or the photosensitive layer 33 to deteriorate adhesion and physically inhibit transfer. .

As shown in FIG. 5, the second sheet 9 is joined and integrated with the second sheet 9 so that the image receiving layer 11 is located inside.

Prior to bonding, it is preferred that images containing personal information be formed on the first sheets 1-8 and/or the second sheets 1-9 by a method other than diffusion transfer imaging.

In particular, the OCR character image 4 is preferably recorded by type printing and/or melt-type thermal transfer, and the recording location is an area other than the area processed by the diffusion transfer method, that is, a non-diffusion transfer processing area. Or preferable.

The information may be recorded on the second sheet 9''.

In order to record the OCR character image 4, it is preferable to use type printing and/or melt-type thermal transfer. 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-fusible substance on a support, and by heating it with a thermal head, an image is transferred to a sheet separate from the ink sheet. is thermally fused and transferred.

As the coloring material for the recording material for melt-type thermal transfer, it is preferable to use a coloring material that has light absorption ability even in the near-infrared region.

Here, "near infrared region J is about 700 to I000 nm
Inorganic pigments or organic pigments such as carbon black, metals, metal oxides, etc. can be used as the coloring material having a light absorption ability or light reflection ability in this wavelength range. In particular, in order to make it readable by an infrared OCR device, carbon black or fine metal powder is preferable.

Metals include iron, copper, aluminum, nickel, lead,
Examples include fine powders of zinc, barium, calcium, tin, silver, etc. Among these coloring materials, carbon black is particularly preferred. The details of the recording material for melt-type thermal transfer are described in Japanese Patent Application No. 1-288256.

When recording the CR character image 4, it is necessary to select a material by taking into consideration its suitability for image formation by the diffusion transfer method.

Thereafter, the first notebook 8 and the second sheet 9 are joined and integrated to form the card 2 containing the person's image.

The bonding layer 13 of the second sheet 9 can be integrated by heating the first sheet 8 and the second sheet 9 in a stacked state in the case of a hot melt type.

982), the adhesives described on pages 139 to 170,
Any known material can be used.

Further, when the image receiving layer II is formed of a thermoplastic resin, by forming the bonding layer 3 of a thermoplastic resin, the two can be stacked and thermally welded to be integrated. This thermal welding means is excellent in that it can effectively prevent counterfeiting and alteration.

Further, in the thermoplastic resins constituting the image-receiving layer 11 and the bonding layer 13, it is preferable that at least some of the repeating units are chemically the same. As such a thermoplastic resin, specifically, polycarbonates, polyacrylates, polyesters, polyvinyl chlorides, etc. are preferable, and polyvinyl chloride is particularly preferable. Regarding this heat welding means, Japanese Patent Application Laid-open No. 2-57395,

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

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

Further, 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.

In this case, since the image formed and recorded on the first sheet 8 is configured to be observed through the transparent support, a horizontally inverted image will be recorded on the image receiving layer 11.

After recording the image, the first sheet 8 and the second sheet 9 are joined and integrated to produce an MRP.

On the other hand, when the support 10 of the first sheet 8 is a reflective support, as shown in FIG.
The booklet 1 and the first sheet 8 can be integrated in advance by joining the side opposite to the side on which the booklet I is layered with the front device 5 of the booklet I. In FIG. 9, the second sheet 9 may be bound to the booklet 1 or may be separated from the booklet l. 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.

Note that the material for the front device 5 is not particularly limited, and materials such as synthetic leather, natural leather, plastic, paper, etc. that are used to construct ordinary notebooks and the like may be used.

FIG. 10 shows the person image-containing card 2 produced as described above. The area 52 processed by the diffusion transfer method using a silver halide photosensitive material (hereinafter referred to as "diffusion transfer processing area") does not occupy the entire surface of the image-receiving layer 11. It is preferable that an optically readable image such as an OCR character and/or an OMR symbol be formed in a region other than the diffusion transfer processing region, that is, a non-diffusion transfer processing region.

The machine reading area 51 is an area that includes the 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 0-750
In the case of the MRP described in No. 1, the machine readable area 51 means the area within about 23 mm from the lower edge.

As shown in FIG. 10, it is preferable that the machine reading area 51 does not overlap the diffusion transfer processing area 52.

Here, the "diffusion transfer processing area" refers not only to an area where a human image or character image intentionally formed by the diffusion transfer method exists, but also to an area where at least a silver halide photosensitive material is stacked in a state where diffusion transfer is possible. It also includes areas where the white background is colored by capri, for example.

In the example shown in FIG. 10, the character image 5 and the graphic image 6 provided if necessary can also be formed by the diffusion transfer method.

On the other hand, in the example shown in FIG. 11, 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. Further, 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 the diffusion transfer processing area 52 is an area that includes character images 5 and graphic images 6 as shown in FIG. 10, it is preferable to apply a colored pattern to this background. Coloring of parts can be made less noticeable.

In order to produce the above MRP, for example, JP-A-1-27
No. 7837, No. 1-278355, No. 1-20609
No. 8, No. 1-11099.2, No. 1-109333, No. 1-283190, No. 1-306853, No. 1
It is possible to use manufacturing apparatuses described in publications such as No. 319039 and No. 2-24653.

〔Effect of the invention〕

As explained in detail above, according to the manufacturing method of the present invention, since there is a portion where a diffusion transfer image is not formed, it is possible to prevent unnecessary coloring from occurring during image transfer by the diffusion transfer method. .

Therefore, it is possible to produce a card with a person image of high quality in appearance, and it is also possible to improve the reading accuracy of optically readable images such as OCR characters, OMR symbols, and bar codes.
