EMBODIMENT OF THE INVENTION Hereinafter, with reference to drawings etc., embodiment of this invention is described.

(First embodiment)

Fig. 1 is a view and a cross-sectional view of a card 1 of a first embodiment seen from the winding surface.

Fig. 1(A) is a view of the card 1 viewed from the winding surface.

Fig. 1(B) is a cross-sectional view (cross-sectional view taken along line B-B in Fig. 1(A)) for explaining the layer configuration of the card 1 .

Fig. 1(C) is an enlarged view showing an arrow (C) portion of Fig. 1(B).

In the embodiment and the drawings, the longitudinal direction of the card 1 as viewed from the winding surface (card upper surface 1a) is referred to as the left-right direction X, the transverse direction is referred to as the longitudinal direction Y, and the thickness direction is referred to as Z. In each figure, the magnitude|size is exaggerated suitably in order to show clearly the structure etc. of thickness direction Z.

[Configuration of card (1)]

The card 1 is an IC card capable of communicating with an external device such as a reader/writer.

The card 1 is, in order from the upper side (Z2) to the lower side (Z1), the printed layer 10, the transparent layer 20, the intermediate layer 30 (colored sheet layer), the module substrate 40, the intermediate layer 50 ), the transparent layer 60 is laminated.

The printing layer 10 is formed on the uppermost layer of the card 1 .

In the printed layer 10, a pattern layer 11 and an adhesive layer 12 (hiding layer) are laminated in order from the upper side (Z2) to the lower side (Z1), and a laser processing area 15 (transparent layer exposed part) ) is provided.

The pattern layer 11 is a layer on which a pattern having a name or the like of the card 1 is printed. The pattern layer 11 is formed by offset printing.

The adhesive layer 12 is formed in smooth printing by silk printing. The adhesive layer 12 adheres between the printed layer 10 and the transparent layer 20 .

In addition, the adhesive layer 12 has the following functions.

ㆍSince the adhesive layer 12 is formed in a smooth print 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 express the color tone of the pattern layer 11 well.

- The adhesive layer 12 conceals the internal structure of the card 1 so that it cannot be visually recognized in the state that this card 1 is observed from the printing layer 10 side (upper side Z2).

Further, 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 (eg, silver or white).

The laser processing region 15 is a region in which the transparent layer 60 is exposed when a part of the printed layer 10 is removed by laser processing. In FIG. 1 , the shape of the laser processing area 15 is the shape of the letter of the owner name "ABCD EFGH" of the card 1 .

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

The intermediate layer 30 is the core layer of the card 1 .

As for the intermediate|middle layer 30, the printed layer 31 (coloring sheet printed layer) and the base material layer 32 (base material) are laminated|stacked in order from upper side Z2.

The print layer 31 is printed on the upper side Z2 of the base material layer 32 in a color different from the color of the base material layer 32 itself. The print layer 31 is formed by smooth printing of silk printing. The color of the printed layer 31 is gold-based or silver-based.

The base layer 32 is a layer serving as a core of the intermediate layer 30 . For example, it is a resin sheet, such as PC, PET-G, and PVC. The color of the base material layer 32 itself is generally a white type widely distributed in the market. For this reason, the base material layer 32 can be obtained at low cost.

The module board 40 includes electronic components 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, a password for authenticating the owner, and the like.

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 etching or the like. The IC chip 41 transmits/receives information to/from the reader/writer in a non-contact manner via the antenna 42 .

The module substrate 40 is formed of, for example, a material such as PET or PEN. For this reason, it is difficult for the module substrate 40, the intermediate layer 30, and the intermediate layer 50 to be thermally welded. Therefore, the external shape of the module substrate 40 is one dimension smaller than the external shape of the other layers.

Accordingly, the module substrate 40 is held in the card 1 by thermally welding the intermediate layer 30 and the intermediate layer 50 on the periphery 45 outside the module substrate 40 .

Since 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, detailed description is omitted. On the lower surface or upper surface of the transparent layer 60, printing (not shown) explaining how to use a card and the like is made.

In addition, in order to improve the adhesive strength between the transparent layer 60 and the intermediate|middle layer 50, you may perform the silk printing for adhesion on either one of the transparent layer 60 and the intermediate|middle layer 50 on the whole surface.

[Appearance of card (1)]

The external appearance of the card 1 is demonstrated.

(Card top (1a))

As shown in FIG. 1C , in the laser processing region 15 , the printed 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 printed layer 31 of the intermediate layer 30 can be visually recognized from the laser processing area 15 (see arrow L). ). Thereby, the observer can read the name of the owner of the card 1 with the laser processing area 15 as gold or silver-colored characters.

In the region other than the laser processing region 15, the pattern of the pattern layer 11 can be observed.

The color of the printed layer 31 of the intermediate layer 30 is not limited to gold or silver, and can be appropriately changed according to card specifications and the like. Thereby, the card 1 can set the character color to a desired color.

(card end face (1b))

As shown in Fig. 1B, on the card end surface 1b, layers other than the module substrate 40 (printed layer 10, transparent layer 20, intermediate layer 30, intermediate layer 50, The transparent layer 60) is exposed.

The base layer 32 of the intermediate layer 30 and the base layer of the intermediate layer 50 are white, and since the intermediate layer 50 and the transparent layer 60 are transparent, it is observed that the card end surface 1b is almost white. .

Moreover, although the printed layer 31 of the intermediate|middle layer 30 is exposed on the card end surface 1b, the thickness of the layer is thin enough. For this reason, even if the printed layer 31 is exposed to the card end surface 1b, it does not stand out and does not reduce an external appearance remarkably.

[Card Manufacturing Method]

The manufacturing process of the card 1 is demonstrated.

Fig. 2 is a cross-sectional view for explaining the manufacturing process of the card 1 according to the first embodiment.

An operator, a manufacturing machine, etc. can manufacture the card 1 according to the following process.

In fact, card manufacturing is performed by dividing a sheet material (that is, a sheet material having multiple faces) in which a plurality of cards 1 are arranged in the plane direction into individual cards. Fig. 2 schematically shows an example of one sheet.

(Transfer process of the printed layer 10)

As shown in Fig. 2A, a PET sheet or the like (not shown) on which the printed layer 10 in the state before the laser processing region 15 is processed 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|stacked on the transparent layer 20. FIG.

The PET sheet or the like is peeled off from the transparent layer 20 after the printing layer 10 is transferred.

(Printing process of the printed layer 31)

On the entire surface of the upper surface of the substrate layer 32, the printing layer 31 is formed by silk printing (refer to the arrow A30), and the intermediate layer 30 is produced.

(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 printed layer 10 is transferred are laminated|stacked, and the laminated body (1A) to produce

(heat press process)

The laminate 1A is sandwiched between hot press plates (not shown) from the top and bottom, and heated and pressurized on the upper surface of the printed layer 10 and the lower surface of the transparent layer 60 .

As shown in FIG.2(B), thereby, the interlayer of the laminated body 1A is heat-welded. When the predetermined press time has elapsed, the hot press plate is separated from the laminate 1A, and the laminate 1A is taken out.

(reorganization process)

1A of laminated body formed with multiple surfaces is pressed with a trimming die, and it is set as individual pieces.

(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 laminated body 1A divided into pieces is laser processed by a laser processing machine to form a transparent layer exposed portion. In this laser processing, by laser irradiation, the printing layer 10 is removed 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 issuance. That is, the laser processing step may be performed as a step of writing the cardholder's unique information (account number, password, etc.) into the IC chip 41 and a series of steps.

Here, at the time of laser processing, the printing layer 10 heat|fever-generates. Since the transparent layer 20 is formed on the intermediate layer 30 , this heat is hardly transmitted to the intermediate layer 30 . In addition, since the color of the printed layer 31 of the intermediate layer 30 is gold-based or silver-based, heat and laser light are reflected.

For this reason, the card 1 can suppress the damage of the intermediate|middle layer 30 accompanying laser processing. That is, the card 1 can remove all the printed layers 10 of the laser processing region 15 without damaging the intermediate layer 30 by the transparent layer 20 or the like.

In addition, the processing conditions (laser output, processing time, etc.) of laser processing must be adjusted so that all of the printed layers 10 are removed in the laser processing area|region 15, and the intermediate|middle layer 30 may not be damaged. As described above, since the card 1 is less affected by heat by the intermediate layer 30 or the like, the width of this adjustment becomes large, so that condition setting is easy.

In addition, it was confirmed that the card 1 in which the transparent layer 20 has a thickness of 0.05 mm or more can be processed without damage to the intermediate layer 30 by trial production and the effect that conditions can be easily set.

Through the above steps, the card 1 can be manufactured.

As described above, in the card 1 , characters and the like on the card face are displayed by removing the laser processing area 15 of the print layer 10 . For this reason, the display does not disappear due to wear or the like. In addition, since the card 1 can form 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 addition, in the description and drawings of the second embodiment, the same reference numerals or the same reference numerals at the end (last two digits) are appropriately attached to parts having the same function as those of the first embodiment described above, and the overlapping description is appropriately omitted. do.

3 is a diagram showing a card 201 according to the second embodiment.

Fig. 3A is a cross-sectional view of the card 201 viewed from the winding surface.

Fig. 3B is a cross-sectional view taken along line B-B in Fig. 3A.

In addition, in the structure after 2nd Embodiment, and the code|symbol in the drawing, "S" is attached to a silver related part, and "G" is attached to a gold related part, as appropriate.

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 (color sheet print layer) of the intermediate layer 230 of the card 201 has a gold print area 231G printed in gold and a silver print area 231S printed in silver. That is, the printing layer 231 is formed by printing two colors (a plurality of colors) in two areas.

In the state seen from the top of the card, the name area 215G is set in the gold print area 231G, and the account number area 215S is set in the silver print area 231S.

With the above configuration, when viewed from the top of the card, the gold color of the gold print area 231G is observed in the name area 215G, and the characters are observed in the gold color. In the account number area 215S, the silver color of the silver printing area 231S is observed, and the character is observed with the silver color.

In this way, in the laser processing area 215, the color of the card 301 observed in the name area 215G and the account number area 215S is different. Thereby, the design of the card 201 can be improved.

In addition, the printing layer 231 is not limited to gold|metal color and silver, and other colors may be sufficient as it, Moreover, it is not limited to these two colors, 3 or more colors may be sufficient as it. In addition, the print layer 231 may be formed by gradation printing in which a color changes continuously. In this case, the character can be observed as if the color changes slowly and continuously.

(Third embodiment)

Next, a third embodiment of the present invention will be described.

In addition, in the description and drawings subsequent to the third embodiment, the same code or the last (last two digits) is appropriately attached to the same code or the last part (last two digits) to the part which performs the same function as the above-mentioned 1st and 2nd embodiment, and to overlap. A description is appropriately omitted.

4 is a diagram showing a card 301 according to the third embodiment.

Fig. 4A is a cross-sectional view of the card 301 viewed from the winding surface.

Fig. 4(B) is a cross-sectional view taken along line B-B in Fig. 4(A).

In the configuration after the third embodiment and the reference numerals in the drawings, “W” is attached to the relevant part in white as appropriate.

The printed layer 331G of the intermediate layer 330 is a layer printed in gold color on the base layer 32 .

In addition, the printed layer 310 is, in order from the upper side (Z2) to the lower side (Z1), the pattern layer 11, the white printed layer 312W (first color printed layer), the silver printed layer 312S ( a second color printing layer).

The white printed layer 312W is a white (first color) printed layer.

The silver printed layer 312S is a printed layer of silver (second color) which is a different color from the white printed layer 312W. Like the adhesive layer 12 of the first embodiment, the silver printed layer 312S is a layer that also functions as interlayer adhesion, improvement of color tone of the pattern layer 11, concealment of the internal configuration, and the like.

The laser processing area of the card 301 is: name area 315G (transparent layer exposed portion), account number area 315W (first color printed layer exposed portion), deadline area 315S (second color printed layer exposed portion) ) is provided.

These regions 315G, 315W, and 315S are processed to have different depths because the laser irradiation intensity (intensity of laser beam itself, dot density of laser beam, etc.) during processing is different from each other.

In the name area 315G, the entire printed layer 310 is removed by laser irradiation, that is, the printed layer 310 is removed to the extent that the transparent layer 20 is exposed when viewed from the top of the card.

In the account number area 315W, the print layer 310 is removed until the pattern layer 11 is removed by laser irradiation, that is, the white print layer 312W is exposed when viewed from the top of the card.

In the limited area 315S, the printed layer 310 is formed until the pattern layer 11 and the white printed layer 312W are removed by laser irradiation, that is, the silver printed layer 312S is exposed when viewed from the top of the card. the removed part.

With the above configuration, when viewed from the top of the card, in the name area 315G, as in the second embodiment, the gold color of the print layer 331G is observed, and the characters are observed in the gold color. In addition, in the account number area 315W, the white color of the white printing layer 312W is observed, and the character is observed with the white color. In the limit area 315S, the color of the silver print layer 312S is observed, and the character thereof is observed in the color of silver.

In this way, the observed colors of the respective 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.

In addition, the printing method of the white printing layer 312W and the silver printing layer 312S is not limited to silk printing, Other printing methods may be sufficient.

For example, the white printing layer 312W is an offset printing layer, and the silver printing layer 312S may be a silk printing layer with a thicker coating film than that of offset printing in general. In general, a silk printing layer is more difficult to remove by laser irradiation than an offset printing layer, ie, it is less likely to be dissipated by laser irradiation, disappear due to gasification, or the like. For this reason, at the time of laser irradiation which removes the white printing layer 312W which is an offset printing layer, WHEREIN: Since removing even the silver printing layer 312S which is a silk printing layer can be suppressed, workability is good.

Also, between the pattern layer 11 and the white printing layer 312W, a hiding layer such as silver having a hiding power may be formed 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 this hiding layer other than the pattern layer 11 .

In addition, the color printing layer of the print layer 310 is not limited to two colors, You may express three or more colors by laminating|stacking three or more layers. In this case, various colors may be expressed, for example, by forming three layers of three primary colors (yellow, magenta, cyan, etc.) and selectively observing these layers by dot processing by laser irradiation. Also in this case, you may provide a hiding layer between each layer.

(Fourth embodiment)

Next, a fourth embodiment of the present invention will be described.

In addition, in the description and drawings of the fourth embodiment, the same reference numerals or the same reference numerals are appropriately attached to the last (last two digits) to the parts having the same function as those of the above-described third embodiment, and the overlapping description is omitted appropriately. do.

Fig. 5 is a diagram showing a card 401 according to the fourth embodiment.

FIG. 5A is an enlarged view of a part of the letter "A" in the name "ABCD EFGH" (refer to FIG. 4A) in the name area 415a as viewed from the front page.

Fig. 5B is a cross-sectional view taken along line B-B in Fig. 5A.

The layer structure of the card 401 of this embodiment is the same as that of the third embodiment, and only the form of the name region 415a of the laser processing region 415 is different from the third embodiment.

As shown in Fig. 5(A) , the letter “A” in the name area 415a is observed as being framed. When the card upper surface is viewed, the inside 415G (transparent layer exposed portion) of the letter "A" and the edge portion 415S (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 concave portion. However, the depth of the bottom is different between the inner 415G and the edge portion 415S thereof. What is necessary is just to make the intensity|strength of laser irradiation different in the process from which the depth of a bottom part differs in this way similarly to 3rd Embodiment.

The interior 415G has the same shape as the name area 315G (refer to 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 shape as the limit region 315S (refer to FIG. 4 ) of the third embodiment. For this reason, when the edge part 415S is observed from the upper surface of the card, the silver printed layer 312S is exposed.

For this reason, the letter "A" is observed as a gold-colored character of the printed layer 331G through the transparent layer 20 in the inner 415G, and by the silver color of the silver printed layer 312S in the frame portion 415S. It is observed as if the gold characters of the printed layer 331G were framed.

The same is true for other characters in the name area 415a. Thereby, the card 401 can show the name area 415a three-dimensionally like embossing. In addition, the card 401 may improve design.

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 limit region 515a of the laser processing region 515 is different from the third embodiment.

As shown in FIG. 6A , the character “1” in the time limit area 515a is observed as being surrounded by a frame. When the upper surface of the card is seen, the inside 515S (exposed portion of the second color printed layer) of the character "1" and the edge portion 515W (the exposed portion of the first color printed layer) are continuous.

As shown in FIG. 6B , the inside 515S of the character “1” and the frame portion 515W are formed by one concave portion. However, the depth of the bottom is different between the inner 515S and the edge portion 515W thereof. In the processing in which the depth of the concave portion of the character "1" differs in this way, similarly to the third embodiment, the laser irradiation intensity may be different from each other.

The interior 515S has the same shape as the limit region 315S of the third embodiment. For this reason, when the inside 515S is observed from the card upper surface, the silver printing layer 312S (2nd color printing layer) is exposed.

The frame 515W has the same shape as the account number area 315W of the third embodiment. For this reason, when the edge part 515W is observed from the card upper surface, the white printing layer 312W (1st color printing layer) is exposed.

For this reason, the character "1" is observed as a character of silver color (second color) of the silver printing layer 312S in the interior 515S, and the white (second color) of the white printing layer 312W in the frame portion 515W. 1 color), it is observed as if the silver characters of the silver printing layer 312S were framed.

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. 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 middle region 615S change gradually as they reach the inner side. The depth changes linearly. What is necessary is just to make the intensity|strength of laser irradiation stronger as it reaches|attains to the inside of processing of such depth.

In the inner region 615G, similarly to the name region 315G, the printed layer 30 is removed by laser irradiation to the extent that the transparent layer 60 is exposed.

The outer area 615W has the same shape 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 printed layer 312W (first color printed layer) is exposed.

The intermediate region 615S has the same shape as the limit region 315S. For this reason, when the intermediate area|region 615S is observed from the card upper surface, the silver printing layer 312S (2nd color printing layer) is exposed.

In the inner region 615G, as described above, the transparent layer 60 is exposed.

Thereby, the design of the card 601 can be improved.

In addition, the cross-sectional shape of the bottom part of the outer side area|region 615W and the middle area|region 615S is not limited to the form which changes linearly, For example, it may be curved. In this form, since the white color of the white printed layer 312W of the outer region 615W and the silver color of the silver printed layer 312S of the middle region 615S change in complexity, a complex shape can be expressed. In this form of processing, it is necessary to change the intensity of laser irradiation in a complicated manner according to the laser irradiation resistance of the white print layer 312W and the silver print layer 312S. It is difficult to reproduce the same shape. For this reason, if it is this form, the counterfeit suppression effect can be improved.
