Description

The present invention relates to a laminated card for embossed character formation, whose appearance does not become dull even when the colored portion of the embossed character is worn.

For credit cards and membership cards, cards having embossed characters (protruding characters and symbols formed on the front surface of the card) are often used.
The purpose of forming the embossed characters on the card, copy the traces of embossed characters in the document, in order to leave evidence card is utilized.
In the credit card member store, a sales slip issuing machine called an imprinter is deployed, and when a customer pays using a credit card, the customer's credit card is attached to a predetermined position of the imprinter, A sales slip is placed on the sales slip, and the embossed characters of the credit card are copied onto the sales slip by a pressure roller from above the sales slip.
The stamp of embossed characters formed on the card is copied to the sales slip by copying carbon or a color capsule. Enter the amount in the usage amount column of the sales slip, sign the customer, give the customer a portion of the sales slip as a customer copy, leave the member store copy in the member store, and send the remaining slip to the credit card company To do.

          In the case of a cash card, when the cash card is inserted into an automatic teller machine (ATM) or the like, the ATM takes the cash card, copies the embossed letter imprints formed on the card on the wrapping paper so that the cash card is visible. Leave evidence used in ATM.

As described above, the embossed character is effectively used as a means for physically copying the evidence that the card has been used.
In addition, since a credit card or the like is used internationally, it is made in conformity with the ISO (International Organization for Standardization) standard.
The card manufacturer prints on the front and back of the opaque core material, pastes a transparent protective sheet to a predetermined thickness, forms a magnetic stripe or IC module on the outermost surface, and issues a card that conforms to the ISO standard doing.

          In order to comply with the ISO standard, the thickness of the card is 0.76 mm ± 10%. Many credit cards are laminated by laminating three or more sheets. In order to facilitate printing on the card, a plurality of core sheets are formed, and in order to protect print information printed on the card from abrasion, the printing portion is covered with a protective sheet.

          In many cases, the embossed characters formed on the card color the top of the embossed characters. Some of the above-mentioned card member stores do not have an imprinter installed. In such a member store, the card number is posted on the sales slip while visually checking the embossed characters formed on the card. Therefore, the embossed characters are colored to make it easy to see, and the wrong number is not written on the slip.

In the past, a “chipping card and a chipping device for this card” have been provided (see, for example, Patent Document 1).
According to Patent Document 1, in a card issuing device that handles a plurality of types of cards for general members, semi-special members, special members, etc. at the same time, the chipping color ( The color of the top of the embossed letters mentioned above may also be different, for example, gold, silver, white, etc. If you try to chip in different colors in this way, for example, the type of card Replace the ribbon every time (A), provide as many chipping devices as the required number of colors (B), adopt a so-called multi-color ribbon in which a plurality of color areas are alternately provided on one ribbon (C), etc. Can be mentioned.
However, in the case of the above-mentioned A, there is a trouble of exchanging the ribbon every time the type of card is changed, and in the case of B, the device is large and expensive, while the use of a chipping device is limited. The types of colors that can be produced are limited.
In the case of C, in addition to the need to add a sensor and control function for detecting the ribbon color to the chipping device, the ribbon becomes expensive and a wasteful area is generated in the ribbon, making it difficult to change or add color. Furthermore, there is a problem that the types of ribbons increase.
Therefore, as a chipping method that can be colored according to the type of card without adding or changing the conventional device, a chipping sheet for coloring is attached to the embossed portion of the card in a peelable manner, and the chipping sheet A card for chipping in which a colored paint is applied to the card side surface is provided.

Although not shown, the core sheet may be composed of one sheet, or may be composed of two or three sheets as described above. The core sheet is usually composed of a milky white sheet having high opacity in order to shield light.

With reference to FIG. 3, a cross section taken along line BB in FIG. 1 will be described.
FIG. 3 shows a cross section of the embossed character “1” in FIG.
As described in FIGS. 2 and 5, the embossed letter-forming laminated card has three core sheets and two core sheets. In any case, the outer side of the core sheets 102 and 104 is used. Transparent front protective sheets 101 and 105 are laminated on the surface.
The front design printing layer 11 is formed on the exposed surface of the front protective sheet 101 of the embossed character forming laminated card, and the colored layer 120 is printed on the embossed character forming scheduled portion on the back side of the front protective sheet 101.
The colored layer 120 is formed of a printing ink having the same color as the colored layer 20 of the embossed portion applied to the laminated card.
Since the color of the colored layer 20 of the embossed character portion is determined in advance, the transfer foil to be used is obtained, and the ink printed on the embossed character formation planned portion is prepared according to the color of the transfer foil, and screen printing is performed. It is printed by the method.
In the embossed character formation scheduled portion, a medium resin that adheres well to the front core sheet 102 and the front protective sheet 101 is selected as the ink used for the colored layer 120 because an impact is applied when the embossed character is formed .

In FIG. 3, in the card that is frequently used, the colored layer 20 of the embossed character portion is gradually thinned by friction and finally disappears.
At that time, the ink of the front symbol print layer 11 formed on the back side of the front protective sheet 101 is exposed, and when the ink of the front symbol print layer 11 is worn away and disappears, the colored layer 120 becomes visible. Since the above-mentioned colored layer 120 is protected by the front protective sheet 101, it does not easily wear and does not disappear over a long period of time.
That is, the top of the embossed character once becomes the ink color of the design print layer 11, but finally returns to the same color as the colored layer 20 of the embossed character portion.

With reference to FIG. 4, another example of the laminated card for embossed character formation of the present invention will be described.
In the laminated card for embossed character formation shown in FIG. 4, a transparent surface protective sheet 101 is laminated on the outer surface of the core sheet 102 of three core sheets 102, 103, 104, and the outer surface of the core sheet 104 A laminated card having a transparent back protective sheet 105 laminated thereon.
The embossed letter forming laminated card shown in FIG. 4 is a cross-sectional view taken along the line AA of the embossed laminated card in which the front symbol printed layer on the front (front) surface of the card is formed on the back side of the front protective sheet 101 in FIG. Is shown.

As described above, the front design print layer 11 is formed on the back side of the front protective sheet of the embossed character forming laminated card, and the colored layer 120 is printed on the embossed character formation scheduled portion.
The colored layer 120 is formed of a printing ink having the same color as the colored layer of the embossed character portion applied to the laminated card.
Further, a back pattern printed layer 13 is formed between the back protective sheet 105 and the back core sheet 104.
The colored layer 120 and the back pattern print layer 13 are printed on the front core sheet 102 and the back core sheet 104 side, respectively.
Although not shown, the core sheet may be composed of a single sheet.
The core sheets 102, 103, and 104 are usually composed of milky white sheets having high opacity in order to block light.

In a card that is used frequently, the colored layer of the embossed character portion gradually becomes thinner due to friction and eventually disappears. At that time, the front symbol printed layer 11 formed on the back side of the front protective sheet 101 shown in FIG. 4 is exposed.
The example of FIG. 3 is the same, but in many cases, the front symbol print layer 11 is made of offset ink.
On the other hand, when embossed characters are formed on the laminated card, the base material sheet expands in the vicinity of the top of the convex portion of the embossed characters , and the area increases.
Since the front pattern printing layer 11 composed of the above-described offset ink lacks flexibility, a crack occurs near the top of the convex portion of the embossed character , and is formed on the back side of the front surface printing layer 11 between the cracks. The ink in the colored portion 120 is exposed.
In other words, the top of the convex portion of the embossed character is structurally the ink color of the surface design printed layer 11 but substantially looks the same color as the colored layer 20 of the embossed character portion.
