(Embodiment)
Embodiments of the present invention will be described below with reference to the drawings.
(First embodiment)
Drawing 1 is a figure which looked at card 1 of a 1st embodiment from the ticket surface, and a sectional view.
FIG. 1A is a view of the card 1 as seen from the ticket surface.
FIG. 1B is a cross-sectional view (a cross-sectional view taken along the line BB in FIG. 1A) illustrating the layer structure of the card 1.
FIG. 1C is an enlarged view of an arrow C portion in FIG.
In the embodiment and the drawings, the longitudinal direction of the card 1 as viewed from the ticket surface (the card upper surface 1a) is referred to as the left-right direction X, the lateral direction as the longitudinal direction Y, and the thickness direction Z. In each drawing, the size and the like of the thickness direction Z and the like are appropriately exaggerated for the sake of clarity.

[Configuration of card 1]
The card 1 is an IC card that can communicate with an external device such as a reader / writer.
In the card 1, a printing layer 10, a transparent layer 20, an intermediate layer 30 (colored sheet layer), a module substrate 40, an intermediate layer 50, and a transparent layer 60 are laminated in order from the upper side Z 2 to the lower side Z 1.

The print layer 10 is provided on the uppermost layer of the card 1.
The print layer 10 includes an image layer 11 and an adhesive layer 12 (hidden layer) that are stacked in order from the upper side Z2 to the lower side Z1, and includes a laser processing region 15 (transparent layer exposed portion).
The picture layer 11 is a layer on which a picture having the name of the card 1 is printed. The pattern layer 11 is provided by offset printing.
The adhesive layer 12 is provided as a solid by silk printing. The adhesive layer 12 adheres between the printed layer 10 and the transparent layer 20.
The adhesive layer 12 has the following functions.
-Since the adhesive layer 12 is provided by solid printing on the lower surface of the pattern layer 11, the pattern layer 11 is easy to express a desired color. For this reason, the adhesive layer 12 can improve the color of the pattern layer 11.
The adhesive layer 12 conceals the card 1 so that the internal configuration of the card 1 cannot be visually recognized when the card 1 is observed from the printed layer 10 side (upper side Z2).
Note that these functions are more effective when the adhesive layer 12 is made of ink having a hiding power and a color having a hiding power (for example, silver or white).

  The laser processing region 15 is a region where the transparent layer 60 is exposed by removing a part of the printing layer 10 by laser processing. In FIG. 1, the shape of the laser processing region 15 is a character shape of the name “ABCD EFGH” of the owner of the card 1.

  The transparent layer 20 is a transparent layer. The transparent layer 20 is, for example, a resin sheet such as PC (polycarbonate), PET-G (glycol-modified polyethylene terephthalate), PVC (vinyl chloride).

The intermediate layer 30 is a core layer of the card 1.
In the intermediate layer 30, a printing layer 31 (colored sheet printing layer) and a base material layer 32 (base material) are laminated in order from the upper side Z2.
The print layer 31 is printed on the upper side Z <b> 2 of the base material layer 32 in a color different from the color of the base material layer 32 itself. The printing layer 31 is provided by silk printing solid printing. The color of the printing layer 31 is gold or silver.
The base material layer 32 is a layer that becomes the core of the intermediate layer 30. For example, it is a resin sheet such as PC, PET-G, or PVC. The color of the base material layer 32 itself is a white system that is generally widely distributed in the market. For this reason, the base material layer 32 can be obtained at low cost.

The module substrate 40 includes an electronic component such as an IC chip 41 and an antenna 42.
The IC chip 41 is a semiconductor integrated circuit element. The IC chip 41 stores, for example, the owner of the card 1 and a password for authenticating the owner.

  The antenna 42 is a loop coil antenna that communicates with an external reader / writer (not shown). The antenna 42 is a conductor formed on the upper surface of the module substrate 40 and is formed by a method such as etching. The IC chip 41 transmits and receives information to and from the reader / writer via the antenna 42 in a non-contact manner.

The module substrate 40 is formed from a material such as PET or PEN, for example. For this reason, the module substrate 40 and the intermediate layer 30 and the intermediate layer 50 are hardly thermally welded. Therefore, the outer shape of the module substrate 40 is slightly smaller than the outer shapes of the other layers.
As a result, the module substrate 40 is held in the card 1 by heat-welding the intermediate layer 30 and the intermediate layer 50 around the outer periphery 45 of the module substrate 40.

Since the intermediate layer 50 and the transparent layer 60 are symmetrical with respect to the intermediate layer 30 and the transparent layer 20 in the thickness direction Z, detailed description thereof is omitted. On the lower surface or upper surface of the transparent layer 60, printing (not shown) for explaining a card usage method and the like is provided.
In order to improve the adhesive strength between the transparent layer 60 and the intermediate layer 50, silk printing for adhesion may be performed on the entire surface of either the transparent layer 60 or the intermediate layer 50.

[Appearance of card 1]
The appearance of the card 1 will be described.
(Card upper surface 1a)
As shown in FIG. 1C, the laser processing region 15 is in a state where the printing layer 10 is removed and the transparent layer 20 is exposed. When the observer observes the card 1 from the upper side Z2, the color of the upper surface of the printing layer 31 of the intermediate layer 30 can be visually recognized from the laser processing region 15 (see arrow L). Thereby, the observer can read the name of the owner of the card | curd 1 by making the laser processing area | region 15 into a golden or silver character.
Moreover, the pattern of the pattern layer 11 can be observed in areas other than the laser processing area 15.
The color of the printing layer 31 of the intermediate layer 30 is not limited to gold or silver, and can be changed as appropriate according to card specifications and the like. Thereby, the card | curd 1 can make a character color a desired color.

(Card end face 1b)
As shown in FIG. 1B, layers (printing layer 10, transparent layer 20, intermediate layer 30, intermediate layer 50, transparent layer 60) other than module substrate 40 are exposed on card end surface 1b.
The base layer 32 of the intermediate layer 30 and the base layer of the intermediate layer 50 are white, and the intermediate layer 50 and the transparent layer 60 are transparent, so that the card end surface 1b is observed to be almost white. Is done.
The printed layer 31 of the intermediate layer 30 is exposed on the card end surface 1b, but the thickness of the layer is sufficiently thin. For this reason, even if the printing layer 31 is exposed to the card end surface 1b, it does not stand out and does not significantly deteriorate the appearance.

[Card manufacturing method]
A manufacturing process of the card 1 will be described.
FIG. 2 is a cross-sectional view illustrating the manufacturing process of the card 1 of the first embodiment.
An operator, a manufacturing machine, etc. can manufacture the card | curd 1 according to the following processes.
Actually, the card is manufactured by dividing a sheet material (that is, a multi-sided sheet material) in which a plurality of cards 1 are arranged in the surface direction into individual cards. FIG. 2 illustrates a simple example.

(Transfer process of printing layer 10)
As shown in FIG. 2A, a PET sheet or the like (not shown) on which the printing layer 10 in a state before processing of the laser processing region 15 is previously formed is transferred onto the transparent layer 20 (see arrow A10). ). In addition, although the pattern layer 11 is offset printing with low adhesiveness, since the adhesive layer 12 exhibits adhesion, it can be laminated on the transparent layer 20.
The PET sheet or the like is peeled off from the transparent layer 20 after the printing layer 10 is transferred.
(Printing process of printing layer 31)
The printing layer 31 is provided by silk printing on the entire upper surface of the base material layer 32 (see arrow A30) to produce the intermediate layer 30.
(Lamination process)
In order from the upper side Z2, the transparent layer 20, the intermediate layer 30, the module substrate 40, the intermediate layer 50, and the transparent layer 60 to which the printing layer 10 has been transferred are laminated to produce a laminate 1A.

(Hot press process)
The laminated body 1A is sandwiched from above and below by a hot press plate (not shown), and heated and pressed from the upper surface of the printed layer 10 and the lower surface of the transparent layer 60.
As shown in FIG. 2B, the layers of the laminated body 1A are thereby thermally welded. When a predetermined pressing time has elapsed, the hot press plate is separated from the laminate 1A, and the laminate 1A is taken out.
(Single piece process)
The laminated body 1 </ b> A formed by multi-sided pressing is pressed into pieces by a punching die.

(Laser processing process (transparent layer exposed part forming process))
As shown in FIG. 1, when the name of the card owner (applicant) is available, the transparent layer exposed portion is formed by laser processing the separated laminate 1A with a laser processing machine. In this laser processing, the printed layer 10 is removed by laser irradiation until the transparent layer 20 remains and the transparent layer 20 is exposed.
In addition, you may perform a laser processing process at the time of card | curd issuance. That is, the laser processing step may be performed in a series of steps including writing the cardholder's unique information (account number, password, etc.) to the IC chip 41.

Here, the printing layer 10 generates heat during laser processing. This heat is not easily transmitted to the intermediate layer 30 because the transparent layer 20 is provided on the intermediate layer 30. Moreover, since the color of the printing layer 31 of the intermediate layer 30 is gold or silver, it reflects heat and laser light.
For this reason, the card | curd 1 can suppress the damage of the intermediate | middle layer 30 accompanying laser processing. That is, the card 1 can remove all the printing layers 10 in the laser processing region 15 without damaging the intermediate layer 30 by the transparent layer 20 or the like.
Further, the laser processing conditions (laser output, processing time, etc.) must be adjusted in the laser processing region 15 so that the print layer 10 is completely removed and the intermediate layer 30 is not damaged. Since the card 1 is not easily affected by heat by the intermediate layer 30 or the like as described above, the range of this adjustment is increased, and the condition setting is easy.
In addition, the card 1 with the thickness of the transparent layer 20 having a thickness of 0.05 mm or more has confirmed the effect that the intermediate layer 30 can be processed without damage and the condition setting is easy by trial manufacture.
The card | curd 1 can be manufactured through the above process.

  As described above, the card 1 is provided with the display of characters and the like on the card ticket surface by removing the laser processing region 15 of the printing layer 10. For this reason, the display does not disappear due to wear or the like. Further, since the card 1 can form a character display by laser processing, a transfer ribbon such as ultra-graphic printing is unnecessary, and the cost is low.

(Second Embodiment)
Next, a second embodiment of the present invention will be described.
In the description of the second embodiment and the drawings, the same reference numerals or the same reference numerals are added to the end (the last two digits) as appropriate for the parts that perform the same functions as those of the first embodiment described above, and they overlap. Description is omitted as appropriate.
FIG. 3 is a diagram illustrating the card 201 according to the second embodiment.
FIG. 3A is a cross-sectional view of the card 201 as seen from the ticket surface.
FIG. 3B is a cross-sectional view taken along the line BB in FIG.
Note that, in the configurations and the reference numerals in the drawings after the second embodiment, “S” is appropriately added to the silver related portion and “G” is added to the gold related portion.

The laser processing area 215 (transparent layer exposed portion) of the card 201 includes a name area 215G and an account number area 215S.
The print layer 231 (colored sheet print layer) of the intermediate layer 230 of the card 201 includes a gold print region 231G printed in gold and a silver print region 231S printed in silver. That is, the print layer 231 is formed by printing two colors (a plurality of colors) in two regions.
When viewed from the top of the card, the name area 215G is provided in the gold print area 231G, and is provided in the account number area 215S and the silver print area 231S.

With the above configuration, when observed from the upper surface of the card, in the name area 215G, the golden color of the golden print area 231G is observed, and the character is observed in the golden color. In the account number area 215S, the silver color of the silver print area 231S is observed, and the character is observed in the silver color.
As described above, the card 301 has different colors to be observed in the name area 215G and the account number area 215S in the laser processing area 215. Thereby, the design of the card 201 can be improved.

  The print layer 231 is not limited to gold and silver, and may be other colors, and is not limited to these two colors and may be three or more colors. Further, the print layer 231 may be formed by gradation printing in which the color changes continuously. In this case, the character can be observed so that the color gradually and continuously changes.

(Third embodiment)
Next, a third embodiment of the present invention will be described.
In the description and drawings subsequent to the third embodiment, parts having the same functions as those of the first and second embodiments described above are appropriately given the same reference numerals or the same reference numerals at the end (last two digits). Thus, overlapping description will be omitted as appropriate.
FIG. 4 is a diagram illustrating a card 301 according to the third embodiment.
FIG. 4A is a cross-sectional view of the card 301 viewed from the ticket surface.
FIG. 4B is a cross-sectional view taken along the line BB in FIG.
In the configuration and the reference numerals in the drawings after the third embodiment, “W” is appropriately added to the white related portion.

The printed layer 331G of the intermediate layer 330 is a layer printed in gold on the base material layer 32.
The printing layer 310 includes a pattern layer 11, a white printing layer 312W (first color printing layer), and a silver printing layer 312S (second color printing layer) in order from the upper side Z2 to the lower side Z1.
The white print layer 312W is a white (first color) print layer.
The silver print layer 312S is a silver (second color) print layer having a color different from that of the white print layer 312W. Similar to the adhesive layer 12 of the first embodiment, the silver print layer 312S is a layer that also functions as adhesion between layers, improvement of the color of the pattern layer 11, concealment of the internal configuration, and the like.

The laser processing region of the card 301 includes a name region 315G (transparent layer exposed portion), an account number region 315W (first color printed layer exposed portion), and a time limit region 315S (second color printed layer exposed portion).
These regions 315G, 315W, and 315S are processed at different depths because the intensity of laser irradiation during processing (the intensity of the laser light itself, the dot density of the laser light, etc.) is different from each other.

The name region 315G is a portion where the entire print layer 310 is removed by laser irradiation, that is, the print layer 310 is removed until the transparent layer 20 is exposed when viewed from the upper surface of the card.
In the account number area 315W, the pattern layer 11 is removed by laser irradiation, that is, the printed layer 310 is removed until the white printed layer 312W is exposed when viewed from the upper surface of the card.
The time limit region 315S is a portion where the pattern layer 11 and the white print layer 312W are removed by laser irradiation, that is, the print layer 310 is removed until the silver print layer 312S is exposed when viewed from the upper surface of the card.

With the above configuration, when observed from the upper surface of the card, in the name area 315G, the gold color of the print layer 331G is observed and the characters are observed in the gold color, as in the second embodiment. In the account number area 315W, the white color of the white print layer 312W is observed, and the character is observed in the white color. In the time limit region 315S, the color of the silver print layer 312S is observed, and the character is observed in a silver color.
As described above, the observed colors of the regions 315G, 315W, and 315S of the laser processing region 315 are different from each other. Thereby, the design of the card 301 can be improved.

The printing method of the white printing layer 312W and the silver printing layer 312S is not limited to silk printing, and other printing methods may be used.
For example, the white printing layer 312W may be an offset printing layer, and the silver printing layer 312S may be a silk printing layer that generally has a thicker coating than offset printing. In general, the silk print layer is less likely to be removed by laser irradiation than the offset print layer, that is, it is less likely to be burned out by laser irradiation or lost due to gasification. For this reason, since it can suppress removing to the silver printing layer 312S which is a silk printing layer at the time of the laser irradiation which removes the white printing layer 312W which is an offset printing layer, workability is good.

  Further, a concealing layer made of silver or the like having a concealing power may be provided between the pattern layer 11 and the white print layer 312W in order to improve the hue of the pattern layer 11. In this case, in the account number area 315W, the white printing layer 312W may be exposed by removing this concealment layer in addition to the pattern layer 11.

  Furthermore, the color print layer of the print layer 310 is not limited to two colors, and may express three or more colors by stacking three or more layers. In this case, for example, three layers of three primary colors (yellow, magenta, cyan, etc.) are provided, and various colors can be expressed by selectively observing these layers by laser processing. Also good. Also in this case, a concealing layer may be provided between the layers.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described.
In the description of the fourth embodiment and the drawings, the same reference numerals or the same reference numerals are added to the end (the last two digits) as appropriate for the parts that perform the same functions as those of the third embodiment described above, and are duplicated. Description is omitted as appropriate.
FIG. 5 is a diagram illustrating a card 401 according to the fourth embodiment.
FIG. 5A is an enlarged view of the letter “A”, which is a part of the name “ABCD EFGH” (see FIG. 4A) in the name area 415a, as viewed from the ticket surface.
FIG. 5B is a cross-sectional view taken along the line BB in FIG.
The layer configuration of the card 401 of this embodiment is the same as that of the third embodiment, and only the form of the name area 415a of the laser processing area 415 is different from that of the third embodiment.

As shown in FIG. 5A, the letter “A” in the name area 415a is observed as if it was trimmed. When the top surface of the card is viewed, the inside 415G (transparent layer exposed portion) of the letter “A” and its edge 415S (color print layer exposed portion) are continuous.
As shown in FIG. 5B, the interior 415G and the edge 415S are formed by one recess. However, the depth of the bottom portion is different between the inner portion 415G and the edge portion 415S. In this way, the processing in which the depths of the bottoms are different may be such that the intensity of laser irradiation is different between the two as in the third embodiment.

The interior 415G has the same form as the name area 315G (see FIG. 4) of the third embodiment described above. For this reason, when the inside 415G is observed from the upper surface of the card, the transparent layer 20 is exposed.
The edge portion 415S has the same form as the time limit region 315S (see FIG. 4) of the third embodiment. For this reason, when the edge 415S is observed from the upper surface of the card, the silver printing layer 312S is exposed.
For this reason, the letter “A” is observed as a gold character of the print layer 331G through the transparent layer 20 in the inner portion 415G, and the gold character of the print layer 331G is outlined by the silver color of the silver print layer 312S in the edge portion 415S. Observe as.
The same applies to other characters in the name area 415a. Thus, the card 401 can make the name area 415a appear three-dimensionally like embossing. Further, the design of the card 401 can be improved.

(Fifth embodiment)
Next, a fifth embodiment of the present invention will be described.
Note that in the description and drawings of the fifth embodiment, the same reference numerals or the same reference numerals are added to the end (the last two digits) as appropriate to the portions that perform the same functions as those of the third embodiment described above, and they overlap. Description is omitted as appropriate.
FIG. 6 is a diagram illustrating a card 501 according to the fifth embodiment.
FIG. 6A is an enlarged view of the character “11”, which is a part of “11/17” (see FIG. 4A) of the time limit area 515a, as viewed from the ticket surface.
FIG. 6B is a cross-sectional view taken along the line BB in FIG.
The layer structure of the card 501 of this embodiment is the same as that of the third embodiment, and only the form of the time limit area 515a of the laser processing area 515 is different from that of the third embodiment.

As shown in FIG. 6A, the character “1” in the time limit region 515a is observed as if it was trimmed. When the card upper surface is viewed, the inside 515S (second color print layer exposed portion) of the character “1” and the edge portion 515W (first color print layer exposed portion) are continuous.
As shown in FIG. 6B, the inner portion 515S and the edge portion 515W of the character “1” are formed by one concave portion. However, the depth of the bottom portion is different between the inner portion 515S and the edge portion 515W. As described above, in the processing in which the depth of the concave portion of the character “1” is different, the intensity of laser irradiation may be made different from each other as in the third embodiment.

The interior 515S has the same form as the time limit area 315S of the third embodiment. For this reason, when the inside 515S is observed from the upper surface of the card, the silver print layer 312S (second color print layer) is exposed.
The edge 515W has the same form as the account number area 315W of the third embodiment. For this reason, when the edge 515W is observed from the upper surface of the card, the white print layer 312W (first color print layer) is exposed.
For this reason, the character “1” is observed as a silver (second color) character of the silver print layer 312S in the internal 515S, and the white print layer 312W white (first color) in the edge 515W. It is observed as if the 312S silver characters were outlined. The same applies to other characters in the time limit area 515a. For this reason, the card 501 can make the time limit area 515a appear three-dimensionally like embossing as in the fourth embodiment. Further, the design of the card 501 can be improved.

(Sixth embodiment)
Next, a sixth embodiment of the present invention will be described.
Note that in the description and drawings of the sixth embodiment, the same reference numerals or the same reference numerals are added to the end (the last two digits) as appropriate to the portions that perform the same functions as those of the third embodiment described above, and they are duplicated. Description is omitted as appropriate.
FIG. 7 is a diagram illustrating a card 601 according to the sixth embodiment.
FIG. 7A is a cross-sectional view of the card 601 as seen from the ticket surface.
FIG. 7B is a BB cross-sectional view of FIG.
The layer configuration of the card 601 of this embodiment is the same as that of the third embodiment. The card 601 is newly provided with a mark region 615a of a laser processing region 615, as compared with the third embodiment.

As shown in FIG. 7A, the outer shape of the mark region 615a is an ellipse when viewed from the upper surface of the card.
The mark region 615a includes an outer region 615W (first color print layer exposed portion), an intermediate region 615S (second color print layer exposed portion), and an inner region 615G from the outside toward the center.
The outer region 615W and the intermediate region 615S are continuous, and the intermediate region 615S and the inner region 615G are continuous.

As shown in FIG. 7B, the mark region 615a is formed by one concave portion. In the cross-sectional shape, the depths of the outer region 615W and the intermediate region 615S change so as to gradually increase toward the inside. The depth varies linearly. In such depth processing, the intensity of laser irradiation may be increased as it goes inward.
In the inner region 615G, the printing layer 30 is removed by laser irradiation until the transparent layer 60 is exposed, like the name region 315G.

The outer area 615W has the same form as the account number area 315W. For this reason, when the outer region 615W is observed from the upper surface of the card, the white printing layer 312W (first color printing layer) is exposed.
The intermediate area 615S has the same form as the time limit area 315S. For this reason, when the intermediate region 615S is observed from the upper surface of the card, the silver print layer 312S (second color print layer) is exposed.
As described above, the transparent layer 60 is exposed in the inner region 615G.

  With the above configuration, when the mark area 615a is observed from the upper surface of the card, the white color of the white printed layer 312W is observed in the outer area 615W, the silver color of the silver printed layer 312S is observed in the intermediate area 615S, and the printed layer 331G is observed in the inner area 615G. Gold color is observed. Thereby, the design of the card 301 can be improved.

  In addition, the cross-sectional shape of the bottom part of outer area | region 615W and intermediate | middle area | region 615S is not limited to the form which changes linearly, For example, you may curve. In this form, since the white color of the white print layer 312W in the outer region 615W and the silver color of the silver print layer 312S in the intermediate region 615S change in a complicated manner, a complicated pattern can be expressed. In this form of processing, it is necessary to change the intensity of laser irradiation in a complex manner in accordance with the laser irradiation resistance of the white printed layer 312W and the silver printed layer 312S. Is difficult. For this reason, with this form, the forgery suppression effect can be improved.

(Seventh embodiment)
Next, a seventh embodiment of the present invention will be described.
In the description of the seventh embodiment and the drawings, the same reference numerals or the same reference numerals are added to the end (the last two digits) of the parts that perform the same functions as those of the first embodiment described above to overlap. Description is omitted as appropriate.
FIG. 8 is a diagram illustrating a card 701 according to the seventh embodiment.
FIG. 8A is a cross-sectional view of the card 701 as viewed from the ticket surface.
FIG. 8B is a cross-sectional view taken along the line BB in FIG.
The card 701 is obtained by laminating the printing layer 10 on the base material laminate 730.

The substrate laminate 730 is obtained by laminating laser coloring layers 720 and 721 on the upper and lower surfaces of the substrate layer 32, respectively.
As the base material laminate 730, a sheet material on which the laser coloring layer 720, the base material layer 32, and the laser coloring layer 721 are already laminated may be purchased from the market. Such a sheet material can be manufactured by extrusion molding and is distributed in the market. Or the base material laminated body 730 may heat-seal these each layer by the hot press process at the time of card manufacture (refer FIG. 2).

  In the upper layer configuration of the base material layer 32, the picture layer 11, the adhesive layer 12, the laser coloring layer 720, and the base material layer 32 are laminated in this order from the upper side Z2 to the lower side Z1. This layer configuration is the same as the configuration in which the print layer 31 is removed from the first embodiment, and the laser coloring layer 720 is laminated as a transparent layer.

The laser coloring layer 720 has translucency and is colorless and transparent. The laser coloring layer 720 contains a color former that develops color with laser light. For this reason, the range irradiated with the laser light in the laser coloring layer 720 generates heat and develops black color.
As shown in FIG. 8B, for this reason, in the laser processing region 715, the printing layer 10 is removed, and the laser coloring layer 720 is a laser processing step (transparent layer exposed portion) similar to that in the first embodiment. Color is blackened by the forming step).

  With the above configuration, when observed from the upper surface of the card, the character shape of the name “ABCD EFGH” in the laser processing region 715 is observed in black.

Note that the card 701 of this embodiment may be modified as follows.
(1) Laser irradiation in the laser processing region 715 may be performed to such an extent that the printing layer 10 is removed and the laser coloring layer 720 is not colored black. In this embodiment, since the laser coloring layer 720 in the laser processing region 715 is in a transparent state, the lower layer than the laser coloring layer 720 is observed in the laser processing region 715 as in the first embodiment. For this reason, the name of the laser processing region 715 can be observed by white characters of the base material layer 32.
Further, in this embodiment, the laser coloring layer 720 in the laser processing region 715 may not be colored completely black by adjusting the intensity of laser irradiation. In this case, the name of the laser processing region 715 can be observed with gray letters that are intermediate colors between black and white of the base material layer 32.
Furthermore, in this embodiment, if a print layer similar to the print layer 31 of the first embodiment is provided between the laser coloring layer 720 and the base material layer 32, the name of the laser processing region 715 is the name of the print layer. It can be observed with color.
(2) The card 701 of the present embodiment may be provided with a module substrate as in the first embodiment.
In addition, a printing layer (the pattern layer 11 and the adhesive layer 12) and other layers may be laminated below the laser coloring layer 721 of the substrate laminate 730.

(3) The card 701 of this embodiment may be modified in the same manner as in the second to sixth embodiments. Also in this case, the operations and effects corresponding to the second to sixth embodiments are exhibited. Note that the card (701) of this embodiment may be modified in the same manner as in the second to sixth embodiments, and the above modifications (1) and (2) may be performed.

(Eighth embodiment)
Next, an eighth embodiment of the present invention will be described.
Note that in the description and drawings of the eighth embodiment, portions that perform the same functions as those of the seventh embodiment described above are denoted by the same reference numerals or the same reference numerals at the end (last two digits), and overlapped. Description is omitted as appropriate.
FIG. 9 is a diagram illustrating a card 801 according to the eighth embodiment.
FIG. 9A is an enlarged view of the letter “A”, which is a part of the name “ABCD EFGH” (see FIG. 8A) of the laser processing region 815, as viewed from the ticket surface.
FIG. 9B is a BB cross-sectional view of FIG.
The layer configuration of the card 801 of this embodiment is the same as that of the seventh embodiment, and only the form of the laser processing region 815 (transparent layer exposed portion) is different from that of the seventh embodiment.

As shown in FIG. 9A, the letter “A” in the laser processing region 815 includes an internal portion 815W (colored sheet layer viewing range) and an edge portion 815B (laser coloring viewing range).
The edge portion 815B is continuous with the inner portion 815W in such a manner as to edge the outer side of the inner portion 815W.

The inside 815W is a range in which the laser coloring layer 720 does not cause laser coloring.
The edge portion 815B is a range in which the laser coloring layer 720 is laser-colored.
In the inside 815W and the edge portion 815B, the intensity of laser irradiation during processing (the intensity of the laser light itself, the dot density of the laser light, etc.) is different from each other. That is, the intensity of laser irradiation is such that the printing layer 10 is removed and the laser coloring layer 720 is not colored at the inner portion 815W, while the printing layer 10 is removed and the laser coloring layer 720 is colored at the edge 815B. (Ie, the intensity of laser irradiation is stronger than the inside 815 W).

  With the above configuration, when observed from the upper surface of the card, in the internal 815W, the white color of the base material layer 32 (colored sheet layer) is visible through the laser coloring layer 720, while the edge 815B The black color generated by the laser color development layer 720 is visible. The same applies to other characters in the laser processing region 815. For this reason, the card 801 can make other characters of the laser processing region 815 appear three-dimensionally like embossing. Further, the design of the card 501 can be improved.

Note that the card 801 of the present embodiment may be modified as follows.
(1) The substrate laminate 730 may include a printing layer (colored sheet printing layer) similar to the printing layer 231 of the second embodiment. In this case, in the interior 815W, the color of the printed layer can be observed.
(2) Modifications (1) to (3) of the seventh embodiment can be applied to the card 801 in the same manner.
