(Embodiment)
Embodiments of the present invention will be described below with reference to the drawings and the like.
First Embodiment
FIG. 1 is a cross-sectional view of a card 1 according to the first embodiment as viewed from a ticket surface.
FIG. 1A is a view of the card 1 as seen from the face of a ticket.
FIG. 1 (B) is a cross-sectional view (taken along the line BB in FIG. 1 (A)) for explaining the layer structure of the card 1.
FIG. 1C is an enlarged view of a portion C in FIG. 1B.
In the embodiment and the drawings, the longitudinal direction of the card 1 as viewed from the face of the ticket (card upper surface 1a) is referred to as the lateral direction X, the short direction as the longitudinal direction Y, and the thickness direction Z. In each drawing, the configuration in the thickness direction Z etc. is appropriately exaggerated in size in order to clearly show it.

[Configuration of card 1]
The card 1 is an IC card capable of communicating with an external device such as a reader / writer.
In the card 1, a print 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 sequentially stacked from the upper side Z2 to the lower side Z1.

The print layer 10 is provided on the top layer of the card 1.
The print layer 10 has a pattern layer 11 and an adhesive layer 12 (mask layer) sequentially stacked from the upper side Z2 to the lower side Z1, and further includes a laser processing area 15 (transparent layer exposed portion).
The picture layer 11 is a layer on which a picture having the name of the card 1 or the like is printed. The picture layer 11 is provided by offset printing.
The adhesive layer 12 is solidly provided by silk printing. The adhesive layer 12 adheres between the printing layer 10 and the transparent layer 20.
Moreover, the adhesive layer 12 has the following functions.
The adhesive layer 12 is provided on the lower surface of the pattern layer 11 by solid printing, so the pattern layer 11 can easily express a desired color. For this reason, the adhesive layer 12 can improve the color tone of the pattern layer 11.
The adhesive layer 12 hides the internal configuration of the card 1 so that it can not be visually recognized in a state where the card 1 is observed from the printing layer 10 side (upper side Z2).
These functions are more effective when the adhesive layer 12 is made of an ink having a hiding power and a color having a hiding power (for example, silver, white, etc.).

The laser processing area 15 is an area 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 area 15 is a shape of characters of the name “ABCD EFGH” of the holder of the card 1.

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

The middle layer 30 is a core layer of the card 1.
In the middle layer 30, the print layer 31 (colored sheet print layer) and the 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 Z2 of the base layer 32 in a color different from the color of the base layer 32 itself. The print layer 31 is provided by solid printing of silk printing. The color of the printing layer 31 is gold-based or silver-based.
The base layer 32 is a layer to be the core of the intermediate layer 30. For example, resin sheets such as PC, PET-G, and PVC. The color of the base material layer 32 itself is a white-based color generally widely distributed in the market. For this reason, the substrate layer 32 is available 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 device. 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 which 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 without contact with the reader / writer via the antenna 42.

The module substrate 40 is formed of, for example, a material such as PET or PEN. For this reason, the module substrate 40 and the intermediate layer 30 and the intermediate layer 50 are difficult to be heat-welded. Therefore, the outer shape of the module substrate 40 is one size smaller than the outer shape of the other layers.
Thus, the module substrate 40 is held in the card 1 by heat welding the intermediate layer 30 and the intermediate layer 50 in the periphery 45 outside the module substrate 40.

The intermediate layer 50 and the transparent layer 60 are symmetrical to the intermediate layer 30 and the transparent layer 20 in the thickness direction Z, and thus the detailed description will be omitted. On the lower surface or upper surface of the transparent layer 60, printing (not shown) for explaining the 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 top 1a)
As shown in FIG. 1C, in the laser processing area 15, the printing layer 10 is removed and the transparent layer 20 is exposed. When observing the card 1 from the upper side Z2, the observer can visually recognize the color of the upper surface of the printing layer 31 of the intermediate layer 30 from the laser processing area 15 (see arrow L). Thereby, the observer can read the name of the owner of the card 1 as the laser processing area 15 as a gold or silver character.
Moreover, the pattern of the pattern layer 11 can be observed in the area other than the laser processing area 15.
In addition, the color of the printing layer 31 of the intermediate | middle layer 30 is not limited to gold | metal | money or silver color, According to a card | curd specification etc., it can change suitably. Thereby, the card 1 can make the character color a desired color.

(Card end 1b)
As shown in FIG. 1B, layers (the printing layer 10, the transparent layer 20, the intermediate layer 30, the intermediate layer 50, and the transparent layer 60) other than the module substrate 40 are exposed at the card end face 1b.
Since 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, it is observed that the card end face 1 b is substantially white. Be done.
Although the printing layer 31 of the intermediate layer 30 is exposed to the card end face 1b, the thickness of the layer is sufficiently thin. For this reason, even if the printing layer 31 is exposed to the card end face 1b, it does not stand out and does not significantly reduce the appearance.

[Card manufacturing method]
The manufacturing process of the card 1 will be described.
FIG. 2: is sectional drawing explaining the manufacturing process of the card | curd 1 of 1st Embodiment.
An operator, a manufacturing machine or the like can manufacture the card 1 according to the following steps.
In addition, in fact, card manufacture is performed by segmenting the sheet material (that is, sheet material with multiple faces) in which a plurality of cards 1 are arranged in the surface direction into each card. 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 print layer 10 in the state before processing of the laser processing area 15 is 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 expresses adhesiveness, 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 transfer of the printing layer 10.
(Printing process of printing layer 31)
The print layer 31 is provided on the entire upper surface of the base layer 32 by silk printing (see arrow A30), and the intermediate layer 30 is produced.
(Lamination process)
The transparent layer 20 to which the printing layer 10 has been transferred, the intermediate layer 30, the module substrate 40, the intermediate layer 50, and the transparent layer 60 are laminated in order from the upper side Z2 to produce a laminated body 1A.

(Heat pressing process)
The laminate 1A is sandwiched by a heat press plate (not shown) from above and below, and heat and pressure are applied from the upper surface of the print layer 10 and the lower surface of the transparent layer 60.
As a result, as shown in FIG. 2B, the layers of the laminate 1A are thermally welded. When a predetermined pressing time has elapsed, the heat press plate is separated from the laminate 1A, and the laminate 1A is taken out.
(Individual process)
The laminate 1A formed by multi-faced bonding is pressed into individual pieces by a punching die.

(Laser processing process (transparent layer exposed part formation process))
As shown in FIG. 1, when the name of the card holder (applicant) is obtained, the transparent laminated body 1A is laser-processed by a laser processing machine to form a transparent layer exposed portion. In this laser processing, the printing layer 10 is removed by laser irradiation until the transparent layer 20 remains and the transparent layer 20 is exposed.
The laser processing process may be performed at the time of card issuance. That is, the laser processing process may be performed in a series of processes, including a process of writing card card's unique information (account number, personal identification number, etc.) in the IC chip 41.

Here, the printing layer 10 generates heat during laser processing. This heat is hard to be 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-based or silver-based, it reflects heat and laser light.
Therefore, the card 1 can suppress damage to the intermediate layer 30 caused by laser processing. That is, the card 1 can remove all the printing layers 10 of the laser processing area 15 by the transparent layer 20 and the like without damaging the intermediate layer 30.
Further, the processing conditions (laser power, processing time, etc.) of the laser processing should be adjusted in the laser processing area 15 so as to completely remove the print layer 10 and not to damage the intermediate layer 30. As described above, since the card 1 is less susceptible to heat due to the intermediate layer 30 and the like, the range of this adjustment becomes large, so setting of conditions is easy.
In addition, the card | curd 1 whose thickness of the transparent layer 20 is 0.05 mm or more has confirmed the effect of being able to process the intermediate | middle layer 30 without damage by trial manufacture, and being easy to set conditions.
The card 1 can be manufactured through the above steps.

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 area 15 of the printing layer 10. Therefore, the display does not disappear due to wear and the like. In addition, since the card 1 can form a character display by laser processing, a transfer ribbon such as ultragraphic printing is not necessary, 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 at the end (last two digits) are appropriately attached to portions performing the same functions as the first embodiment described above The description will be omitted as appropriate.
FIG. 3 is a view showing a card 201 of the second embodiment.
FIG. 3A is a cross-sectional view of the card 201 as viewed from the ticket surface.
FIG. 3 (B) is a cross-sectional view taken along the line BB in FIG. 3 (A).
In addition, "S" is attached | subjected to a silver related part suitably, and "G" is attached | subjected to a gold related part to the structure after 2nd Embodiment and the code in a figure.

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 area 231G printed in gold and a silver print area 231S printed in silver. That is, in the printing layer 231, two colors (a plurality of colors) are printed and formed 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.

According to the above configuration, when observed from the top of the card, in the name area 215G, the gold color of the gold printed area 231G is observed, and the character is observed in the gold 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.
Thus, in the laser processing area 215, the card 301 has different observed colors between the name area 215G and the account number area 215S. Thereby, the card 201 can improve the design.

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

Third Embodiment
Next, a third embodiment of the present invention will be described.
In the description and the drawings of the third embodiment and the subsequent embodiments, the same reference numerals or the same reference numerals (last two digits) are given to the portions having the same functions as the first and second embodiments described above. Therefore, duplicate descriptions will be omitted as appropriate.
FIG. 4 is a view showing a card 301 of the third embodiment.
FIG. 4A is a cross-sectional view of the card 301 as viewed from the face of the ticket.
FIG. 4 (B) is a cross-sectional view taken along the line BB in FIG. 4 (A).
In the configurations after the third embodiment and the reference numerals in the drawings, "W" is added to the white related parts as appropriate.

The print layer 331G of the intermediate layer 330 is a layer printed in gold on the base layer 32.
Moreover, the printing layer 310 is equipped with the pattern layer 11, the white printing layer 312W (1st color printing layer), and the silver printing layer 312S (2nd color printing layer) in order toward the lower side Z1 from upper side Z2.
The white print layer 312W is a white (first color) print layer.
The silver print layer 312S is a silver (second color) print layer which is a color different from 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 tone of the pattern layer 11, concealment of the internal configuration, and the like.

The laser processing area of the card 301 includes a name area 315G (transparent layer exposed part), an account number area 315W (first color print layer exposed part), and a deadline area 315S (second color print layer exposed part).
These

regions

315G, 315W, and 315S are processed to different depths because the intensities of the laser irradiation (the intensity of the laser light itself, the dot density of the laser light, etc.) at the time of processing are different from each other.

The name area 315G is a portion where the entire printing layer 310 is removed by laser irradiation, that is, the printing layer 310 is removed until the transparent layer 20 is exposed when viewed from the top of the card.
The account number area 315W is a portion from which the pattern layer 11 is removed by laser irradiation, that is, the print layer 310 is removed until the white print layer 312W is exposed when viewed from the top of the card.
The time limit area 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 top of the card.

According to the above configuration, when observed from the top of the card, in the name area 315G, the gold color of the print layer 331G is observed in the same manner as in the second embodiment, and the characters are observed in the gold color. In addition, in the account number area 315W, the white color of the white print layer 312W is observed, and the characters are observed in the white color. In the deadline area 315S, the color of the silver print layer 312S is observed, and the character is observed in the silver color.
Thus, the

areas

315G, 315W, and 315S of the laser processing area 315 have different observed colors. Thereby, the card 301 can improve the design.

In addition, the printing method of the white printing layer 312W and the silver printing layer 312S is not limited to silk printing, You may be another printing method.
For example, the white print layer 312W may be an offset print layer, and the silver print layer 312S may be a silk print layer that is generally thicker than the offset print. In general, a silk print layer is more difficult to be removed by laser irradiation than an offset print layer, that is, it is hard to be burnt off by laser irradiation, disappear by gasification, and the like. For this reason, at the time of the laser irradiation which removes the white print layer 312W which is an offset print layer, since it can suppress that the silver print layer 312S which is a silk print layer is removed, it has good processability.

In addition, between the pattern layer 11 and the white print layer 312 W, a shielding layer such as silver having a shielding power may be provided in order to improve the color tone of the pattern layer 11. In this case, in the account number area 315W, the white print layer 312W may be exposed by removing the concealing layer in addition to the pattern layer 11.

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

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 at the end (last two digits) are appropriately attached to portions performing the same functions as the third embodiment described above The description will be omitted as appropriate.
FIG. 5 is a view showing a card 401 of the fourth embodiment.
FIG. 5A is an enlarged view of a letter “A” which is a part of the name “ABCD EFGH” (see FIG. 4A) of the name area 415a, as viewed from the ticket surface.
FIG. 5 (B) is a cross-sectional view taken along the line BB in FIG. 5 (A).
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 bordered. When looking at the upper surface of the card, the inside 415 G (transparent layer exposed portion) of the character “A” and its edge 415 S (color printed layer exposed portion) are continuous.
As shown in FIG. 5B, the inner portion 415G and the edge portion 415S are formed by one recess. However, the depth of the bottom differs between the inside 415G and its edge 415S. As described above, in the processing in which the depth of the bottom portion is different, as in the third embodiment, the intensity of the laser irradiation may be made different between the two.

The inside 415G has the same form as the name area 315G (see FIG. 4) of the third embodiment described above. Therefore, when the inside 415G is observed from the top of the card, the transparent layer 20 is exposed.
The edge 415S has a form similar to that of the time limit area 315S (see FIG. 4) of the third embodiment. Therefore, when the edge 415S is observed from the top surface of the card, the silver print layer 312S is exposed.
For this reason, the letter "A" is observed as a golden character of the printing layer 331G through the transparent layer 20 in the interior 415G, and the edge of the golden character of the printing layer 331G by the silver color of the silver printing layer 312S at the edge 415S As observed.
The same applies to the other characters in the name area 415a. Thereby, the card 401 can make the name area 415a appear three-dimensional like embossing. In addition, the card 401 can improve the design.

Fifth Embodiment
Next, a fifth embodiment of the present invention will be described.
In the description of the fifth embodiment and the drawings, the same reference numerals or the same reference numerals at the end (last two digits) are appropriately attached to portions performing the same functions as the third embodiment described above The description will be omitted as appropriate.
FIG. 6 is a view showing a card 501 of 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 surface of the ticket.
FIG. 6 (B) is a cross-sectional view taken along the line BB in FIG. 6 (A).
The layer configuration of the card 501 of this embodiment is the same as that of the third embodiment, and only the form of the deadline region 515a of the laser processing region 515 is different from that of the third embodiment.

As shown in FIG. 6A, the letter "1" in the due date area 515a is observed as bordered. When looking at the upper surface of the card, the inside 515 S (second color print layer exposed portion) of the character “1” and its edge 515 W (first color print layer exposed portion) are continuous.
As shown in FIG. 6B, the inside 515 S of the character “1” and the edge 515 W are formed by one recess. However, the depth of the bottom differs between the inside 515S and its edge 515W. As described above, in the processing with different depths of the concave portion of the character "1", the intensities of the laser irradiation may be made different from each other as in the third embodiment.

The inside 515S has the same form as the time limit area 315S of the third embodiment. Therefore, 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 a form similar to that of the account number area 315W of the third embodiment. Therefore, when the edge 515W is observed from the top surface of the card, the white print layer 312W (first color print layer) is exposed.
For this reason, the character "1" is observed as the silver (second color) character of the silver print layer 312S in the interior 515S, and the silver print layer is formed by the white color (first color) of the white print layer 312W at the edge 515W. It is observed as bordering a silver character of 312S. The same applies to the other characters of the due date area 515a. For this reason, the card 501 can make the time-limited area 515a appear three-dimensionally like embossing, as in the fourth embodiment. In addition, the card 501 can improve the design.

Sixth Embodiment
Next, a sixth embodiment of the present invention will be described.
In the description of the sixth embodiment and the drawings, the same reference numerals or the same reference numerals at the end (last two digits) are appropriately attached to portions performing the same functions as the third embodiment described above The description will be omitted as appropriate.
FIG. 7 is a view showing a card 601 of the sixth embodiment.
FIG. 7A is a cross-sectional view of the card 601 as viewed from the face of the ticket.
FIG. 7B is a cross-sectional view taken along the line BB in FIG. 7A.
The layer configuration of the card 601 of the present embodiment is the same as that of the third embodiment. The card 601 is the one in which a mark area 615a of the laser processing area 615 is newly provided in the third embodiment.

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

As shown in FIG. 7 (B), the mark area 615a is formed by one recess. In the cross-sectional shape, the depths of the outer region 615W and the middle region 615S gradually change in depth toward the inside. The depth varies linearly. The processing of such a depth may be such that the intensity of the laser irradiation becomes stronger as it reaches the inside.
In the inner area 615G, the printing layer 30 is removed by laser irradiation until the transparent layer 60 is exposed, as in the name area 315G.

The outer area 615W has a form similar to that of the account number area 315W. Therefore, when the outer area 615W is observed from the top surface of the card, the white print layer 312W (first color print layer) is exposed.
The middle area 615S has the same form as the time limit area 315S. Therefore, when the middle area 615S is observed from the upper surface of the card, the silver print layer 312S (second color print layer) is exposed.
In the inner region 615G, as described above, the transparent layer 60 is exposed.

According to the above configuration, when the mark area 615a is observed from the upper surface of the card, the white color of the white print layer 312W is observed in the outer area 615W, the silver color of the silver print layer 312S is observed in the middle area 615S, and the print area 331G of the inner area 615G. Gold is observed. Thereby, the card 301 can improve the design.

The cross-sectional shape of the bottom of the outer region 615W and the middle region 615S is not limited to a linearly changing form, and may be curved, for example. In this embodiment, the white color of the white print layer 312W of the outer area 615W and the silver color of the silver print layer 312S of the intermediate area 615S change in a complicated manner, so that a complex pattern can be expressed. In this type of processing, it is necessary to change the intensity of laser irradiation intricately in accordance with the laser irradiation resistance performance of the white print layer 312W and the silver print layer 312S, so similar patterns are reproduced except for card manufacturers. It is difficult. Therefore, in this embodiment, 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 at the end (last two digits) are given to the portions having the same functions as the first embodiment described above, The description will be omitted as appropriate.
FIG. 8 is a view showing a card 701 of the seventh embodiment.
FIG. 8A is a cross-sectional view of the card 701 as viewed from the ticket surface.
FIG. 8 (B) is a cross-sectional view taken along the line BB in FIG. 8 (A).
The card 701 is obtained by laminating the printing layer 10 on the base laminate 730.

The base laminate 730 is formed by laminating the laser coloring layers 720 and 721 on the upper surface and the lower surface of the base layer 32, respectively.
As the base laminate 730, a sheet material on which the laser coloring layer 720, the base layer 32, and the laser coloring layer 721 are already laminated may be purchased from the market. Such sheet material can be manufactured by extrusion molding and distributed in the market. Alternatively, the base laminate 730 may heat-weld these layers by a heat-pressing process (see FIG. 2) at the time of card production.

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

The laser coloring layer 720 is translucent, colorless and transparent. The laser coloring layer 720 contains a color former that develops color by laser light. For this reason, the area of the laser coloring layer 720 irradiated with the laser light generates heat and also turns black.
As shown in FIG. 8B, therefore, in the laser processing area 715, the printing layer 10 is removed, and the laser coloring layer 720 is subjected to the same laser processing step (transparent layer exposed portion as in the first embodiment). It develops a black color by the formation step).

According to the above configuration, when observed from the upper surface of the card, the shape of characters of the name “ABCD EFGH” of the laser processing area 715 is observed in black.

The card 701 of the present embodiment may be modified as follows.
(1) The laser irradiation in the laser processing area 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 of the laser processing area 715 is in a transparent state, a layer lower than the laser coloring layer 720 is observed in the laser processing area 715 as in the first embodiment. For this reason, the name of the laser processing area 715 can be observed with the white letters of the base layer 32.
Further, in this embodiment, by adjusting the intensity of the laser irradiation, the laser coloring layer 720 of the laser processing area 715 may be made not to be completely black colored. In this case, the name of the laser processing area 715 can be observed in gray characters, which are intermediate colors of black and white of the base layer 32.
Furthermore, in this embodiment, if a printing layer similar to the printing layer 31 of the first embodiment is provided between the laser coloring layer 720 and the base layer 32, the name of the laser processing area 715 is the same as that of the printing layer. It can be observed in color.
(2) The card 701 of the present embodiment may be provided with a module substrate as in the first embodiment.
In addition, the printing layer (the picture layer 11, the adhesive layer 12) or another layer may be laminated also below the laser coloring layer 721 of the base laminate 730.

(3) The card 701 of this embodiment may be modified as in the second to sixth embodiments. Also in this case, the operation and effects corresponding to the second to sixth embodiments can be obtained. The card 701 of this embodiment may be modified in the same manner as in the second to sixth embodiments, and then the above (1) and (2) may be modified.

Eighth Embodiment
Next, an eighth embodiment of the present invention will be described.
In the description of the eighth embodiment and the drawings, the same reference numerals or the same reference numerals at the end (last two digits) are given to the portions having the same functions as the seventh embodiment described above The description will be omitted as appropriate.
FIG. 9 is a view showing a card 801 of 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 area 815, as viewed from the ticket surface.
FIG. 9 (B) is a cross-sectional view taken along the line BB in FIG. 9 (A).
The layer configuration of the card 801 of the present embodiment is the same as that of the seventh embodiment, and only the form of the laser processing area 815 (transparent layer exposed portion) is different from that of the seventh embodiment.

As shown to FIG. 9 (A), character "A" of the laser processing area | region 815 is provided with the inside 815W (colored sheet layer visual recognition range) and the edge part 815 B (laser coloring visual recognition range).
The edge 815B is continuous with the interior 815W in such a manner as to border the exterior of the interior 815W.

The inside 815 W is a range in which the laser coloring layer 720 does not emit a laser.
The edge 815B is a range where the laser coloring layer 720 emits a laser.
In the inner portion 815 W and the edge portion 815 B, the intensities of the laser irradiation at the time of processing (the intensity of the laser beam itself, the dot density of the laser beam, and the like) are different from each other. That is, the intensity of the laser irradiation is such that the printing layer 10 is removed and the laser coloring layer 720 is not colored at the inside 815 W, 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 that of the internal 815 W).

According to the above configuration, when observed from the upper surface of the card, the white color of the base layer 32 (colored sheet layer) is visible through the laser coloring layer 720 at the inside 815 W, while the edge 815 B The black color produced by the laser coloration of the laser coloring layer 720 is visible. The same applies to the other characters in the laser processing area 815. For this reason, the card 801 can make the other characters of the laser processing area 815 look three-dimensional like embossing. In addition, the card 501 can improve the design.

The card 801 of the present embodiment may be modified as follows.
(1) The base laminate 730 may have a printing layer (colored sheet printing layer) similar to the printing layer 231 of the second embodiment. In this case, the color of the print layer can be observed in the interior 815W.
(2) The modifications of (1) to (3) of the seventh embodiment can be similarly applied to the card 801.

As mentioned above, although an embodiment of the present invention was described, the present invention is not limited to the embodiment mentioned above, for example, various modification and change are possible like modification etc. which are mentioned below, Within the technical scope of the present invention. Further, the effects described in the embodiment only list the most preferable effects arising from the present invention, and the effects according to the present invention are not limited to those described in the embodiment. In addition, although embodiment mentioned above and the deformation | transformation form mentioned later can also be combined and used suitably, detailed description is abbreviate | omitted.
