CONSTITUTION:The supporting body 52 which reflects light is directly joined with a plastic resin film which constitutes the binding material 53 at temp. higher by at least 20 deg.C than the temp. to heat and laminate a transparent laminate film 4 and a sheet 3 in which a portrait is recorded. The plastic resin film of the binding material 53 is preliminarily joined with thin paper at high temp., and then the light-reflecting supporting body 52 is adhered thereto. The light-reflecting supporting body 52 is made of paper, which prevents forgery or modification and maintains rigidity when the laminate film 4 is adhered to the sheet 3 which records the portrait 31. Thereby, waves in edges of the bound surface and wrinkles in the bound surface can be prevented.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a booklet containing images of people, and in particular, a booklet containing images of people.
At least on the back side of the cover material made of colored plastic resin, the booklet with images of people is bonded to a transparent film under heat, which greatly improves the heat resistance of the cover part and eliminates waving at the edges. To relate to a booklet containing images of people in which wrinkles do not occur on the cover.

[Conventional technology]

ID booklets, such as passports, student handbooks, employee handbooks, etc., contain various personal information such as name, affiliation, personal code, etc., along with a facial photograph, in a part of the handbook or booklet to confirm the identity of the person. There is. Traditionally, there have been cases in which confirmation of such personal information has relied solely on human judgment, and in order to prevent such unauthorized use of ID booklets, various counterfeit and falsification prevention measures have been taken. Most of these methods were often based on human visual discrimination.

In particular, passports require advanced measures to prevent forgery and alteration, and in addition to the conventional human-based visual identification methods, attempts have recently been made to use OCR characters to identify passports.

The present invention relates to a booklet containing images of people that can be read by OCR, such as passports, etc., and has been made in order to solve problems in booklets containing images of people that can be read by OCR.

In other words, MRP (Machine Reader Passport)
In machine-readable booklets containing images of people, such as the above, it is extremely important to ensure reading accuracy. Reading accuracy deteriorates due to various factors. For example, in addition to the character quality of the OCR characters themselves, the presence or absence of dirt on the background on which the OCR characters are printed, or the stability of the reading machine, there is also deterioration in reading accuracy due to the physical characteristics of the booklet itself.

Specifically, unevenness (undulations) on the edges of a booklet, unevenness on the surface of the booklet, etc. have a large effect on character recognition by an OCR reader.

For example, the image recording surface on which ○CR characters or human images are recorded is usually laminated with a transparent resin film, etc. to prevent fraud, but in this case, from the viewpoint of effectively preventing forgery and alteration, It is preferable to perform lamination under heating. In other words, when laminating with an adhesive layer, use an appropriate organic solvent,
In some cases, the laminated film can be peeled off very slowly, making it possible to remove the film relatively cleanly, making it more susceptible to counterfeiting. On the other hand, when bonding by laminating under heating,
The heated surfaces are relatively firmly bonded, and because mass transfer and composition changes occur easily between the bonded surfaces, the bonded surfaces are extremely difficult to peel or leave a clean surface even if peeled. There is. For this reason, it is particularly difficult to forge or alter documents such as passports (hereinafter referred to as "
For booklets containing human images that require "resistance to forgery and alteration", it is preferable to laminate the human image recording surface under heating.

However, in order to ensure sufficient machine reading accuracy for booklets with images of people that are laminated under heat, it is undesirable for air bubbles to enter the laminated surface. It is added when Usually, a pressure of about 0.5 kg or more per cm2 is applied to the laminate surface. If lamination is performed under such heating and pressurizing conditions, the facing material may stretch, or the facing material may swell due to water vapor generated from the paper layer provided between the facing material and the LamiHo 1-Film. However, there is a problem in that waving occurs at the edges of the surface, or wrinkles appear on the surface. Mojiron,
By storing the booklet in advance in a relatively low humidity environment,
Although these problems are improved to some extent, they are not completely resolved.

In particular, when reading OCR characters with a machine, normally an area at a certain distance from the edge is read based on the edge, but as mentioned above, the edge may be wavy. When reading a booklet, the reading accuracy drops significantly because the position of the reading area fluctuates. In addition, if wrinkles occur on the cover of the booklet, it does not simply impair the commercial value of the booklet with human images, but it may also be a problem that the thickness of the surface on which the OCR characters are recorded may change and the reading accuracy may decrease. be.

However, in the past, in such booklets containing images of people, no special efforts were made for the resin that constitutes the cover. For example, Japanese Unexamined Patent Publication No. 2-111590 discloses a booklet with images of people, and resins constituting the cover include polyethylene terephthalate, polycarbonate-1-, acetyl cellulose, cellulose ester, polyhinyl acetal, polystyrene, polyester, etc. Vinyl chloride, nylon, polyethylene, and polypropylene are disclosed. The above-mentioned publication also describes the use of a material in which a mounting material, paper, and these films are laminated together.

[Invention or problem to be solved]

However, when the film described in ``1'' is pasted with paper using an adhesive, as in the case of making a regular notebook, the problem described in ``--'' occurs, that is, the edges of the surface are undulated. It was found that wrinkles may occur on the surface.

Therefore, the first object of the present invention is to prevent the edges from waving and to prevent wrinkles from forming on the surface when a transparent film is bonded under heating to a reflective support that has been bonded to a surface material in advance. To provide a booklet containing images of people that does not cause such problems.

A second object of the present invention is to provide a booklet containing images of people that has high resistance to forgery and alteration and can be easily produced.

Furthermore, a third object of the present invention is to provide a booklet containing human images that has high OCR reading accuracy.

[Means to solve the problem]

The above-mentioned object of the present invention is to provide an image of a person that forms part of a booklet by bonding at least a covering material made of a colored plastic resin, a light-reflecting support, an image recording layer, and a transparent film in this order. The transparent film is bonded to the light reflective support under heat with the image recording layer in between, and the mounting material is heated at a temperature higher than the bonding temperature of the transparent film and the light reflective support. At least 20℃
This is achieved by a booklet with images of people, which is characterized in that it has been pre-laminated onto paper at two elevated temperatures.

[Specific structure of the invention]

Hereinafter, a specific configuration of the present invention will be explained in detail.

The facing material used in the present invention is made of at least a colored plastic resin. Such plastic resins have a glass transition point T from the viewpoint of obtaining flexibility.
g or more than about 60°C. Such plastic resins include polyvinyl chloride, polystyrene,
polyurethane, polyacetal, polymethacrylic acid,
Examples include polyester. Among these, polyvinyl chloride and polyurethane are preferred because they provide good flexibility.

The plastic resin constituting the facing portion may be a single resin or a mixture of two or more types of resins, but a single resin is preferable. Furthermore, a known plasticizer may be added to the plastic resin constituting the facing material in order to impart flexibility to the facing part. Examples of such plasticizers include dibutyl phthalate, octyl phthalate, ricrecylphthalate, dinonyl phthalate, triphenyl phthalate, and the like.

Furthermore, in addition to the plasticizer, the plastic resin may partially contain a relatively flexible resin having a glass transition point Tg of about 30° C. or lower.

Such resins include, but are not limited to, polyvinyl acetate, polyvinylidene chloride, copolymers (vinyl chloride-vinylidene chloride, etc.), polypropylene, and the like.

These plasticizers and resins with a glass transition point Tg of about 30°C or lower are used in an amount of 2 to 40% by weight, preferably 5 to 30% by weight, based on the plastic resin with a glass transition point Tg of about 60°C or higher. Used in the range of %.

The thickness of the facing part is usually 0.1 to 0.5 mm, preferably 0.2 to 0.4 mm. If the thickness of the cover material is too thick, the flexibility of the resulting booklet cover material will be reduced, and the ease of opening and closing the booklet will be reduced. When laminating with film under pressure and heat conditions, the facing part may stretch,
It is easy to create unevenness at the edges. Such irregularities can be OC'd using an OCR reader.
This poses a major obstacle when machine reading characters such as the R character. Furthermore, if the thickness of the cover material is too small, the lamination near the thread binding portion of the booklet will be insufficient, leaving some unlaminated areas, which will greatly reduce the resistance to counterfeiting and alteration.

On the other hand, if the thickness of the plastic resin layer that makes up the surface material is too small, uneven lamination may occur when laminating a transparent film, or pressure marks may remain when laminated. This can easily cause problems.

The plastic resin constituting the covering material contains appropriate pigments and dyes to be colored in a desired color. Further, the mounting material may be subjected to a treatment such as foil stamping at an appropriate stage of the booklet production process.

The facing material is laminated and bonded to paper in advance at a temperature that is at least 20° C. higher than the bonding temperature between the transparent film and the light-reflecting support. This "temperature" does not refer to the surface temperature of the heating roller for joining or the surface temperature of the heated object, but refers to the maximum temperature of the joining surface of the two heated parts to be heated. This "temperature" can be measured by inserting a heat label (for example, manufactured by Ohbe Kogyo Co., Ltd.) or the like between the heating surfaces to visually identify the maximum temperature during heating.

In addition, if the "paper" that is bonded to the mounting material in advance is a light-reflecting support or paper, it may be a part of the support that constitutes the light-reflecting support, and separately from this, For example, after laminating a thin paper with a thickness of 0.025 to 0.05 mm in advance with a covering material at a temperature 20°C or more higher than the bonding temperature between the transparent film and the light-reflecting support, this thin paper portion is exposed to light. It may also be bonded to a reflective support. In the present invention, the latter is preferred because of the heat resistance of the covering material and the resistance to counterfeiting and alteration.

In the present invention, the temperature at which the facing material is bonded to the paper is
The temperature is 20° C. or more higher than the temperature at which the transparent film is laminated with the light-reflecting support as described in Item 1, and particularly preferably 30° C. or more higher. In addition, the bonding temperature when laminating the transparent laminate film with the light reflective support is determined from the viewpoint of effectively preventing the generation of bubbles.
160°C or higher is preferred, and 170°C or higher is particularly preferred.

In the present invention, before joining the facing material to the paper, an appropriate subbing layer may be provided on the paper in advance to facilitate the joining. However, from the viewpoint of reliably preventing the generation of bubbles when laminating the transparent film and the light-reflecting support, it is preferable to bond the transparent film and the light-reflecting support without providing an undercoat layer.

The facing material is either made into a film with a thickness of, for example, 01 to 05 mm, or bonded to paper at a high temperature, but at this time, it is preferable to pressurize it instead of simply heating it. Pressure force is 0.1~]Okg/cm
2 is preferable, and 0.2 to 5 kg/cm2 is particularly preferable. The mounting material obtained by pressurizing in a high temperature state may then be subjected to a cleaning process, if necessary.

Next, a method for producing a booklet containing images of people according to the present invention will be explained using a machine-readable passport as an example.

FIG. 1 is a completed diagram of a booklet containing a person's image according to the present invention that has the shape of a passport, and shows a booklet part 2 having writable pages 11 and an ID part 1 in which face photo information etc. are written. It consists of The ID section 1 includes a personal face photo area 20, a personal character information area (indicated by a circle) 21, and an OCR character information area (△
(represented by a mark) 22, auxiliary portion (pre-printed characters such as "address", "name", etc., represented by an x mark) 23, Saimon (
(not shown) is written or printed. 10 is a thread binding section.

Figure 2 shows the state of the booklet containing images of people in Figure 1 before completion;
That is, it shows the state before laminating the transparent film. This booklet with images of people consists of a transparent film (hereinafter referred to as "laminate film") 4, a sheet 3 on which images of people 31 are transferred, and a booklet part 2 having a plurality of writable pages 11. .

The laminate film 4 has a transparent support layer. Such a support 41 may have a thickness of, for example, approximately 50 to 1
Transparent polyethylene terephthalate with a diameter of about 0.00 μm is used. This laminated film 4 has a human image 3
It is preferable to provide a layer 43 that can be bonded to the sheet 1-3 on which the sheet 1-3 is recorded. This bondable layer 43 is a thermally bondable layer. This thermally bondable layer 43 is preferably a so-called hot-melt adhesive layer or a heat-welding layer, and is particularly preferably a heat-welding layer. The support 41 and the bondable layer 43 are bonded together via an undercoat layer 42, but this undercoat layer 42 is not necessarily required.

Hot Melt Agent Data Book” (published by Nikkan Kogyo Shimbun, 1990)
Published on February 28, 2015, edited by the Adhesion Society of Japan), pp. 139-1
Examples include those listed on page 70.

It is preferable that the sheet 3 and the laminate film 4 be joined by a thermal welding method. What is this “thermal welding method”?
The heat-weldable layers provided on the lamiho 1 to film 4 and the heat-weldable layer provided on the sheet 3 on which a person's image is recorded are directly heat-welded without using a separate adhesive layer. At least some of the possible layers are intermixed to form a complete weld. When joined by such a heat welding method, the laminate sheet =
14 - It is almost impossible to forge or alter an image laminated with a film without destroying it, and it has extremely high resistance to forgery and alteration.

Preferably, such a heat-welding layer is made of a thermoplastic resin such as polyvinyl chloride, polycarbonate, polyisophthalic acid ester, or the like. Along with these thermoplastic resins, polyvinylidene chloride,
Copolymers such as polypropylene and polyvinyl acetate may also be used together. Alternatively, a mixture with the above thermoplastic resin may be used.

The temperature when joining the sheet 3 and the laminate film 4 under heating is usually 100°C or higher, preferably 120°C or higher, particularly preferably 130°C or higher. At such a bonding temperature, the bonding will be more complete;
It becomes almost impossible to peel off the laminate film 4.
Provides excellent counterfeiting and alteration resistance.

Further, when joining the laminate film 4 to the sheet 3, it is preferable to apply a pressure of 01 to 20 J/cm2. As the means for applying this pressure, in order to effectively prevent the generation of air bubbles, it is preferable to use a heating/pressure roller, etc., which normally heats and then presses the booklet from one direction to the other. .

The laminate film 4 may be bonded in advance to at least a portion of the images 1-3 on which the person images of the booklet are recorded, as described in Japanese Unexamined Patent Publication No. 177749/1993.

In FIG. 2, the image recording layer 51 on which the person image 31 is formed is either itself or the layer 43 of the laminate film 4.
It is preferable that the layer can be bonded to.

Such a bondable image recording layer 51 varies widely depending on the layer 43 of the laminate film 4 and the bonding method.
For example, it may be a layer made of a hydrophilic binder mainly composed of ceratin, such as an emulsion layer of photographic paper, or a dye-receiving layer made of a thermoplastic resin capable of receiving image dyes thermally diffused and transferred. In the former case, it is particularly preferable that the image recording layer 51 is bonded by hot-melt adhesive. In the latter case, the image recording layer 51 may be a dye-receiving material onto which a dye image is transferred by a heat-sensitive transfer method, or a heat-developable silver halide photosensitive material as described in JP-A No. 1-193844. Preferably, the material is a dye image-receiving material having a dye image-receiving layer image-formed using the dye image-receiving material.

In FIG. 2, on the image recording layer 51 on which the person image 31 is formed, characters, symbols, color patterns, etc., such as personal information and common information, may be further added to the person image 31 at the same time as the person image 31 or separately. It may be recorded by a recording means different from the recording means for the person image 31.

These letters, symbols, colored patterns, etc. are printed on laminated film 4.
It is also possible to record on the layer 43 of . In the example shown in FIG. 2, characters, symbols, colored patterns, etc. (indicated by 32 in FIG. 2) are recorded on the layer 43 of the laminate film 4.

A preferably white light-reflecting support 52 is bonded to the image recording layer 51 on which the person image 31 is recorded. Usually, an image recording layer 51 is placed on these light reflective supports 52.
The coating is applied in advance by a known suitable coating method.

It is preferable that the light-reflecting support 52 has an opacity that can sufficiently hide the color of the colored mounting material 53. Specifically, the opacity (transmission) of the light-reflecting support 52 is concentration) is preferably 0.7 or more, particularly 0.
．． It is preferable that it is 8 or more.

The light reflecting support 52 is joined to the mounting material 53,
As described above, the light-reflecting support 52 consists of the transparent laminate film 4 and the sheet 3 on which the human image 31 is recorded.
Heating the laminating temperature under at least 20℃
It may be directly bonded to the plastic resin film constituting the facing material 53 at a temperature higher than that, or it may be bonded to the plastic resin film of the facing material 53 or thin paper at a high temperature in advance, and this and the light reflecting support. body 52
Alternatively, they may be joined using a suitable adhesive. In this case, the light-reflecting support 52 is preferably a paper support, a film made of white polyethylene terephthalate, white polyvinyl chloride, etc., but it is especially preferable that the light reflection support 52 is a paper support to prevent forgery or alteration. It is preferable that the rigidity can be maintained when laminating the films 1 to 4 with the notebook 3 on which the person image 3I is recorded. When a paper support is used as the light reflection support 52, even if an attempt is made to forcefully peel off the transparent laminate film 4 laminated on the recording surface of the person image 31, in most cases the paper layer will be destroyed. It exhibits excellent resistance to counterfeiting and alteration.

Figure 3 shows the state of the booklet containing images of people in Figure 1 before completion;
That is, it shows the state before the transparent laminate film 4 is laminated. In this example, the image recording surface is recorded on the image recording layer provided on the transparent laminate film 4, and the characters, color patterns, etc. other than the person image 31 are recorded on the light reflective support bonded to the covering material 53. It is recorded on the joint surface on 52.

In Figures 2 and 3, characters, symbols, colored patterns, etc.
Each may be recorded by the same means as the recording means for the person image 31, or may be recorded by a different means. Further, these characters, symbols, colored patterns, etc. may be recorded only on one side of the joint surface, or may be recorded on both sides of the joint surface.

The transparent laminate film 4, the light-reflecting support 52 bonded to the facing material 53, and the surface layers bonded to each may contain various additives as required.

Examples of such additives include known compounds such as optical brighteners, image stabilizers, and colorants that adjust the color tone of the background.

The booklet containing images of people of the present invention may have a hologram (reflective type or transmissive type), a tally mark, or a colored pattern, if necessary.

FIG. 4 shows an example of a colored pattern. The color pattern 60 has a line width of O,
] It is precisely drawn with fine lines of less than 1 mm, and if the page on which this colored pattern 60 is printed is later modified, it will be difficult to repair it, so it is not resistant to forgery and alteration like passports etc. Although it is often used for various required certificates, it is also useful for the booklet containing images of people of the present invention.

Particularly, as shown in FIG. 4, when the colored pattern 60 is partially overlapped with the face photograph area 20 of an individual, the resistance to forgery and alteration is further increased.

The hologram can be either a foul type or a transparent type,
In the case of a reflective type, it is bonded to an appropriate location on the produced booklet containing human images by a hot stamping method. In the case of a transmission type, the laminate film itself or a hologram sheet may be used, or it may be used by bonding it to the surface of a prepared booklet containing images of people. Particularly, when a transmissive hologram is attached to a completed booklet containing a person's image, it is preferable to partially overlap the face photograph area of the individual from the viewpoint of increasing resistance to forgery and alteration. Fourth
The area indicated by 15 in the figure is an example of an area where a hologram is formed.

Note that the transparent laminate film 4 is heated and heated on the sheet 3.
When laminating under pressure, it is preferable to employ a laminating method using a laminating roller. Also,
It is preferable that the lamination be performed from the leading edge of the booklet toward the thread-stitched portion, since there is less deformation of the end portion due to heating when the final booklet is viewed. In particular, for passports and the like, which are subjected to OCR reading based on the edge of the mounting section 53,
Deformation at the edges of the booklet is undesirable because it reduces the success rate of OCR reading, and therefore it is important to perform welding from the edges to the center of the booklet.

In the image recording section of the booklet, it is preferable that the area to be laminated with the transparent laminate film 4 be the entire surface, but in reality, there are problems with the accuracy of positioning and the fact that the stitching section 10 cannot be completely laminated, or When laminating under heating, the facing material 53 and the laminate film 4 may undergo slight thermal contraction and thermal expansion, so the transparent laminate film 4 is not suitable for the facing material 53 or the integrated sheet 3. It is preferable that each end be narrow by about 2 mm or less, and further considering the appearance, the laminate film 4 should be shorter at the end in the range of 0.3 to 1 mm except for the thread binding part 10. That's preferable. Moreover, in the thread binding part 10, it is preferable that the transparent laminate film 4 is short in the range of 1 to 2 mm.

[Preparation of booklet with images of people]

A booklet containing images of people having the structure shown in FIG. 2 was produced by the following method.

A colored pattern as shown in FIG. 4 was printed on the dye image-receiving layer surface of the image-receiving material using UV curable ink. This printing means that in the completed booklet, the image of the person will be approximately 2.5 mm wide on the two surrounding sides.
This was done at a position where the colored patterns overlapped by 5mm.

Next, this printed image-receiving material and six sheets of high-quality paper corresponding to a plurality of writable pages were superimposed so that the surface of the polyvinyl chloride image-receiving layer overlapped with the writable paper surface. Next, after binding the center with thread, the back side of the image-receiving material (the side opposite to the dye image-receiving layer side of the baryta paper) is attached to the above-mentioned mounting material using a vinyl chloride-vinyl acetate-based latex adhesive. Combined. At this time, the bonding surface is
It was stored day and night under pressure (2 kg/cm2) in a constant temperature bath kept at 40°C.

This pasted product was folded in two around the thread binding portion, and then cut into a predetermined size to produce a booklet containing images of people.

[Image records and production of booklets with individual images]

A CRT image of a person is placed on the heat-developable photosensitive material obtained by the above method.
After exposure with a printer, 150
Heat development was performed at ℃ for 70 seconds. The developed heat-developable photosensitive material is superimposed on the PVC dye image-receiving layer surface of the image-receiving material that has been previously bound in the booklet with images of people, and the layer is superimposed at 135° C. for 8 seconds onto the surface of the image-receiving material. Dye transfer was performed.

Next, after the heat-developable photosensitive material was peeled off from the image-receiving material, necessary information such as characters and symbols were recorded by a melt-type heat-sensitive transfer re-recording method, and then the laminate film was laminated onto the surface of the dye image-receiving layer. The laminate film used was one that had been punched out in advance so that the end was about 0.5 mm inward from the surface of the dye image-receiving layer. The lamination (thermal welding) of the laminate film was carried out by applying a pressure of about 5 kg/cm 2 and heating the film to a temperature of 150° C. and passing it between rollers arranged vertically to face each other. The maximum temperature reached on the laminate surface was 135°C, as measured using a heat label.

[Evaluation of booklet with images of people]

Regarding the booklet containing images of people produced by the above method, (1)
The state of waving at the edges (2) The occurrence of wrinkles on the facing part (3) The change in the gloss of the facing part (4) The rate of occurrence of air bubbles on the laminate surface was checked. The results are shown in Table-2.

The evaluation criteria were as follows.

(1) Waving at the edges 〇 Waving or no waving at all △ Slight waving or tolerable level for practical use None △ Probability of wrinkle occurrence less than 02 per booklet × Probability of wrinkle occurrence 02 or more per booklet, which is practically unacceptable level (3) Gloss change on the cover ○ Gloss change: no change △, slightly A change in gloss is observed, but it is at a practically acceptable level x A change in gloss is too large to be practically acceptable. I made a book and found it.

The results are shown in Table 2 below.

From Table 2, it can be seen that the booklet with images of people of the present invention using a mounting material that has been bonded to paper in advance at a temperature 20°C or more higher than the lamination temperature (135°C) of the laminated film is as follows: It is clear that this booklet is superior to the comparison booklet with human images in terms of waving at the edges, wrinkles on the cover, and changes in gloss on the cover.

In particular, the best heat resistance is exhibited when the front device and the thin paper are bonded together at high temperature without using an adhesive, and moreover, when the thin paper is bonded to the thin paper at a temperature 40° C. or more higher than the lamination temperature.

[Example 2] Using the eight types of mounting materials produced in Example 1, a booklet with images of people was produced in the same manner as in Example 1 by changing the lamination temperature as shown in Table 3 below. The heat resistance was evaluated in the same manner as in Example 1.

The results are shown in Table 3 below.

From Table 3, it can be seen that the booklet containing images of people of the present invention, in which the plastic resin constituting the mounting material is laminated to thin paper at a temperature 20°C or higher than the lamination temperature, has a high temperature resistance and bubble formation at the lamination temperature. It is clear that it is superior.

[Example 3] In the table device I-1 produced in Example 1, the thickness of the polyvinyl chloride sheet) was changed as shown in Table 4 below, and a booklet with human images was prepared in the same manner as in Example 1. Heat resistance and bubble generation during lamination were evaluated.

The results are shown in Table 4 below.

From Table 4, it is clear that the polyvinyl chloride sheet that constitutes the facing material
It can be seen that if the thickness is less than 1 mm or 0.1 mm, the heat resistance of the booklet will be slightly reduced. On the other hand, in any case where the thickness of the polyvinyl chloride sheet I. constituting the cover material exceeded 0.5 mm, the cover part became stiff and the booklet opened and closed easily.

[Example 4] When producing a booklet with images of people using the eight types of mountings produced in Example 1, images of people were recorded by a sublimation type heat-sensitive transfer recording method instead of using a heat-developable photosensitive material. A booklet with human images was produced in the same manner as in Example 1 except for this. The results are shown in Table 5 below.

From Table 5, it was found that the effects of the present invention can be obtained even when images are recorded using a booklet containing images of people.

Table-2 Table-3 Table-4 Table-5 [Effects of the Invention] According to the present invention, the mounting process is performed beforehand at a temperature at least 20°C higher than the bonding temperature of the transparent film and the light-reflecting support. Since it is bonded to paper, the edges may be wavy,
A booklet with beautiful images of people can be obtained without problems such as wrinkles on the cover, changes in gloss on the cover, and residual air bubbles.

Further, the booklet containing images of people of the present invention has high resistance to forgery and alteration, and can be easily produced.

Furthermore, the booklet containing human images of the present invention has high OCR reading accuracy.
