Description

  The present invention relates to a card that is excellent in design and that is fun to hold.

In recent years, membership cards have been issued in various fields to lock in customers.
In athletic facilities, entertainment-related facilities, etc., card members can, for example, use facilities preferentially and purchase products sold in the facility at a lower price than non-members.
A membership card used in a store or the like is issued in the store, and the card member can preferentially obtain campaign information by direct mail or purchase a product at a low member price.
In addition, a point card or the like is issued at the time of product purchase, and point information on the purchase amount of the customer is recorded on the card every time the product is purchased, so that the member can receive a service corresponding to the accumulated points.
In addition, prepaid cards such as gift cards and electronic money are issued and used to purchase goods and services.
Both cards are issued to encourage the purchase of goods for the customer's continued visit.

The above-mentioned membership cards and point cards are issued according to the intentions of facilities and shops. However, customers with a wide range of activities cannot store all cards in their wallets and leave them at home except for cards that are frequently used. In many cases, a neglected card is forgotten.
For this reason, card issuers devise their card designs so that customers can always carry them with them and visit them frequently.

Since credit cards and the like need to be used internationally, they are made in conformity with the ISO (International Organization for Standardization) standard.
A credit card company issues a card that conforms to the ISO standard by pasting a transparent oversheet on the front and back of an opaque core material to a predetermined thickness and forming a magnetic stripe or IC module on the outermost surface.

On the other hand, membership cards and point cards issued at stores and the like do not necessarily conform to the ISO standard, so they are planned and issued with a unique design and a conspicuous design.
Therefore, a card in which a fluorescent dye is kneaded into a part of a card substrate is provided (for example, see Patent Document 1).

In FIG. 1, the partial blank area of the shielding portion 15 is a design area having an “egg” shape, but in FIG. 5, the partial blank area of the shielding portion 15 is a simple blank area. The rectangular light-collecting fluorescent dye printing part 12 is formed in the area.
The shielding unit 15 is designed to shield the magnetic information recording unit 13.
In FIGS. 1 and 5, since the presence of the magnetic information recording unit 13 is shielded by the shielding unit 15, the entire card can be used as a design area without being obstructed by the magnetic stripe.

With reference to FIG. 2, the AA line cross section of FIG. 1 is demonstrated.
As described with reference to FIG. 1, the card base 100 has a laminated structure in which a front cover sheet 101, a front core sheet 102, a back core sheet 103, and a back cover sheet 104 are sequentially laminated.
In the example shown in FIG. 2, the card base 100 has a four-layer structure. However, when it is possible to directly print on a thick sheet, the front core sheet and the back core sheet are integrated into one sheet. It is also possible to make a sheet with a three-layer structure, and conversely, the card base 100 can also have a six-layer structure with two front core sheets and two back core sheets.
Further, the front and back core sheets can be made thin, and a center core can be sandwiched between the front and back core sheets to form a five-layer structure.
A magnetic material layer 13 is formed on the outermost surface side of the front cover sheet 101.
The magnetic material layer 13 is formed in advance on the front cover sheet before the front cover sheet, the front core sheet, the back core sheet, and the back cover sheet are laminated.

On the front cover sheet 101, a shielding layer 15 for shielding the magnetic material layer 13 and a surface design printing portion 11 are sequentially formed. If necessary, as shown in the figure, a protective layer 16 made of a transparent material is formed on the outermost surface to protect the surface design printed portion 11.
The protective layer 16 made of the transparent material, the surface design printing portion 11 and the shielding layer 15 made of the shielding ink are formed in advance on the transfer sheet, and the front cover sheet on which the transfer sheet and the magnetic information recording portion 13 are formed, which will be described later. The front core sheet 102 on which the condensing fluorescent dye printing section 12 is formed, the back core sheet on which the back printed pattern 14 is formed, and the back cover sheet can be sequentially stacked and simultaneously laminated.

A condensing fluorescent dye printing part 12 is formed on the front core sheet 102 by printing.
The condensing fluorescent dye printing unit 12 may be composed of a single layer of the condensing fluorescent dye printing film or a plurality of layers.
In the example shown in FIG. 2, the condensing fluorescent dye printing unit 12 is formed so as to fill a partially blank area of the shielding unit 15 described above.
As a result, when the completed card is viewed from the front cover sheet 101 side, a blank area of “egg shape” is formed while the shielding portion 15 is formed on the entire surface, and collection with yellow transparent ink is formed there. The light-emitting fluorescent dye printing part 12 is designed to be fitted, and the light-collecting fluorescent dye printing part 12 is a part of the design without a sense of incongruity.
The brown to black magnetic material layer 13 is shielded by the shielding layer 15 and is not recognized from the outermost surface.
In this case, the printing color of the shielding layer may be brown to black disguised as a magnetic material, or shields the magnetic material layer by reflection when viewed from the surface (front surface), for example, silver color, It may be gold or white.
Although not shown, in order to disguise the presence of the magnetic material layer more completely, a shielding layer can be provided also in a portion corresponding to the back side of the magnetic material layer of the back core sheet.

A design including characters, ruled lines, and symbols is printed on the surface design printing unit 11 with a transparent or opaque printing ink. Similarly, on the side of the back cover sheet 104 of the back core sheet 103, a back side printed pattern 14 made of characters, ruled lines, symbols or the like is printed with a transparent or opaque printing ink.
The intensity of light emitted from the side surface of the card substrate 100 increases as the printing area of the condensing fluorescent dye printing unit 12 increases and as the printed ink film of the condensing fluorescent dye printing unit 12 increases. growing.
Moreover, the intensity of light emitted from the side surface of the card substrate 100 is higher when the printing ink used for the front-surface pattern printing unit 11 is a transparent ink than when it is an opaque ink.
Furthermore, when the printing ink used for the surface design printing unit 11 is an opaque ink, the intensity of light emitted from the side surface of the card substrate 100 increases as the printing area of the surface design printing unit decreases.

The front cover sheet 101, the front core sheet 102, the back core sheet 103, and the back cover sheet 104 may be laminated by being fused by heat or may be laminated through an adhesive.
When the front cover sheet 101, the front core sheet 102, the back core sheet 103, and the back cover sheet 104 are fused by heat, in order not to use an adhesive for bonding, as described above, The front core sheet 102 and the back core sheet 103 located in the center can be configured by increasing the number of sheets.
On the front core sheet 102, a light-collecting fluorescent dye printing layer 12 and a surface design printing layer 11 are sequentially formed before being laminated.
In addition, a design including characters, ruled lines, and symbols is formed on the surface design printing unit 11 by printing.

With reference to FIG. 3, an example of the mechanism by which the light absorbed from the condensing fluorescent dye printing unit is emitted to the side surface of the card will be described.
FIG. 3 is an enlarged view of the periphery of the front core sheet 102 in FIG.
The “a light” incident in the direction of the arrow from the surface of the condensing fluorescent dye printing unit 12 is reflected by the upper and lower surfaces of the core sheet 102 along the course indicated by the solid line, and is reflected on the side surface of the front core sheet 102. Reach and be released.
Further, the “b light” incident in the direction of the arrow from the surface of the light-collecting fluorescent dye printing unit 12 is reflected by the upper and lower surfaces of the front core sheet 102 along the course indicated by the dotted line, The side of 102 is reached and discharged.
Similarly, the “c light” is reflected by the upper and lower surfaces of the core sheet 102 along the course indicated by the dashed line, and is emitted from the side surface of the front core sheet 102.
As described above, the light absorbed from the condensing fluorescent dye printing unit 12 printed on the core sheet 102 is emitted from the side surface of the core sheet 102 in a concentrated state.

Although not shown, a part of the light absorbed from the light-collecting fluorescent dye printing unit 12 passes through the boundary between the front core sheet 102 and the back core sheet 103 and is emitted from the side surface of the back cover sheet 104. .
When the front cover sheet 101, the front core sheet 102, the back core sheet 103, and the back cover sheet 104 are fused by heat, there is no boundary between the front core sheet 102 and the back core sheet 103, The light absorbed from the condensing fluorescent dye printing unit 12 printed on the front core sheet 102 is emitted from the side surfaces of the front core sheet 102 and the back core sheet 103 in a concentrated state.

With reference to FIG. 4, an example of the characteristic of the condensing fluorescent dye which the absorbed light is converted into the light of a different frequency and is emitted will be described.
The example shown in FIG. 4 shows an example of an absorption spectrum and an emission (excitation) spectrum of a condensing fluorescent dye using “LumogenF Yellow083” manufactured by BASF.
“LumogenF Yellow083” indicates that the maximum absorption wavelength is 476 nm and the maximum emission wavelength is 490 nm.
In other words, when light from a light source with a frequency of 476 nm is irradiated to the light-collecting fluorescent dye printing part using “LumogenF Yellow083”, the light is absorbed without any waste and light with a frequency of 490 nm is emitted from the side surface of the card substrate. Is to do.
This dye has a heat resistance of 300 ° C., and therefore can sufficiently withstand a temperature of 100 to 150 ° C. when the cards are laminated and a lamination time of about 40 to 60 minutes.
Furthermore, in order to maintain a characteristic of 90% or more even after continuous irradiation of a xenon lamp for 2,000 hours (having light resistance), the absorption / emission characteristics of the above-described light-collecting fluorescent dye even when the card is used for a long time Can be maintained within a practical range.

  In addition to the light-collecting fluorescent dye shown in FIG. 4, a dye having a maximum absorption wavelength of 377 nm and a maximum emission wavelength of 411 nm, a dye having a maximum absorption wavelength of 378 nm and a maximum emission wavelength of 413 nm, and a maximum absorption wavelength of 578 nm and a maximum emission wavelength 613 nm dye, maximum absorption wavelength of 524 nm and maximum emission wavelength of 539 nm, etc., all of which have heat resistance and light resistance equivalent to “LumogenF Yellow083”.

With reference to FIGS. 1-4, the usage method and characteristic of the card | curd of this invention are demonstrated.
The front cover sheet 101 or the back cover sheet 104 of the card 1 is directed to sunlight, room light, or a nearby light source.
As a result, the card 1 passes through the front surface symbol printing unit 11 or the back surface symbol printing unit 14 or passes through the gap to absorb the light irradiated by the condensing fluorescent dye printing layer 12, and the card 1 Light having a frequency corresponding to the type of the condensing fluorescent dye is emitted from the side surface of the substrate 100.
Since the light emitted from the side surface of the card substrate 100 is light having a wavelength different from that of the condensing fluorescent dye printing unit 12 printed on the card 1, it exhibits a great effect as a countermeasure against counterfeiting as well as a design effect. To do.
