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 for continuous visits by customers and to encourage purchases of merchandise.

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).

JP-A-2-281999

In the invention described in Patent Document 1, since the fluorescent dye is mixed with the material itself, the card manufacturer cannot use the material used conventionally.
In addition, for a material manufacturer supplying card materials, since a series of molding equipment is contaminated with fluorescent dyes, it takes a lot of time to clean the molding equipment when returning to production of materials that do not use fluorescent dyes. There must be.

  In order to solve the above-mentioned problems, a first aspect of the card of the present invention is a card comprising a single transparent resin material or a laminate of a plurality of transparent resin materials as a card substrate. A condensing fluorescent dye printing part is formed on one surface of the condensing fluorescent dye using a printing ink containing the condensing fluorescent dye, and a strip-shaped print having a width of 0.5 mm to 4.0 mm is formed on the periphery of the condensing fluorescent dye printing part. A blank area is formed.

  In the second aspect, in the first aspect, when the card base is made of a single transparent resin material, a pattern printing part is formed on the surface of the condensing fluorescent dye printing part, The front and back outermost surfaces are covered with a protective layer.

  Further, in the third aspect, in the first aspect, when the card base is formed of a laminate of a plurality of transparent resin materials, between the front cover sheet and the core sheet, or between the core sheet and the back surface. A condensing fluorescent dye printing layer is formed between the cover sheets using a printing ink containing the condensing fluorescent dye.

  The fourth aspect is characterized in that, in the third aspect, a pattern printing part is formed on the surface of the condensing fluorescent dye printing part or the exposed surface of the cover sheet.

  The fifth aspect is any one of the first to fourth aspects, wherein the transparent resin material is any one of an amorphous polyester resin, a polylactic acid resin, and a polyvinyl chloride resin. Is.

  The sixth aspect is characterized in that, in any one of the first to fifth aspects, a magnetic information recording portion is formed on the exposed surface on either the front or back side.

With the card of the present invention,
1) On the card maker side, the transparent card base material that has been used in the past can be used as it is in making the card of the present invention, and it can be printed with a printing ink containing a condensing fluorescent dye only in a predetermined area. Cards can be delivered inexpensively and with short delivery times.
In addition, by forming a strip-shaped printing blank area having a width of 1.0 mm to 5.0 mm around the periphery of the light-collecting fluorescent dye printing portion that forms the light-collecting fluorescent dye printing layer, a laminate having a plurality of card bases In the case of, the card can be provided as a card having no risk of peeling the cover sheet from the core sheet while maintaining the effect that the edge of the card shines with colored light.
2) Since the light emitted from the side surface of the card substrate is light having a wavelength different from that of the light-collecting fluorescent dye printed portion printed on the card, it has a great effect as a countermeasure against counterfeiting as well as a design effect. Demonstrate.
3) Further, since the magnetic recording portion is formed on the exposed surface of the card, the card information can be magnetically recorded, and labor saving such as paperwork can be achieved.

It is a figure for demonstrating an example of the card | curd of this Embodiment. It is for demonstrating an example of the AA line cross section of FIG. It is a figure for demonstrating another example of the cross section of the AA line of FIG. It is a figure for demonstrating an example of the mechanism in which the light absorbed from the condensing fluorescent dye printing part is discharge | released to the side surface of a card | curd. It is a figure for demonstrating an example of the characteristic of the condensing fluorescent dye which converts absorbed light into the light of a different frequency, and discharge | releases.

An example of the card according to the present embodiment will be described with reference to FIG.
The card base 100 of the card 1 according to the present embodiment is a card made of one transparent resin material or a laminate of a plurality of transparent resin materials.
In any case, the transparent resin material is made of a transparent amorphous polyester resin, the transparent resin is made of a polylactic acid resin, and the transparent resin is made of a polyvinyl chloride resin.
A condensing fluorescent dye printing portion 12 is formed on one surface of the card base 100 with a printing ink containing the condensing fluorescent dye, and a width “d” is formed on the periphery of the condensing fluorescent dye printing portion 12. The printing blank area 15 is formed in a strip shape.

A surface design printing portion 11 is formed between the front side exposed surface of the card base or between the front cover sheet and the front core sheet.
Further, a back side printed surface portion (not shown) is formed between the back side exposed surface of the card base or between the back core sheet and the back cover sheet.
In addition, a design including characters, ruled lines, and symbols is applied to the front surface symbol printing unit 11 and the back surface symbol printing unit (not shown) by printing.

With reference to FIG. 2, an example of the cross section along the AA line of FIG. 1 is demonstrated.
The example shown in FIG. 2 is an example of a card in which the card base is made of a laminate of a plurality of transparent resin materials.
The card substrate 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.
A condensing fluorescent dye printing layer 12 is formed between the front cover sheet 101 and the front core sheet 102, and the peripheral edge of the condensing fluorescent dye printing layer 12 is 0.5 mm to 7.0 mm wide. Preferably, a strip-shaped printing blank area 15 having a width of 0.5 mm to 4.0 mm is formed.
In the embodiment shown in FIG. 2, a stripe-shaped magnetic information recording unit 14 is formed on a part of the exposed surface of the back cover sheet 104.
Further, a front surface symbol printing unit 11 is formed on the exposed surface of the front cover sheet 101, and a back surface symbol printing unit 13 is formed between the back core sheet 103 and the back cover sheet 104. The front surface pattern printing unit 11 may be formed on the front cover sheet 101 side of the light-collecting fluorescent dye printing layer 12 between the front cover sheet 101 and the front core sheet 102.
Further, the back surface pattern printing unit 13 may be formed on the exposed surface of the back cover sheet 104.

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 greater when the printing ink used for the front surface graphic 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 are laminated by being fused by heat or bonded through an adhesive.
The front cover sheet 101, the front core sheet 102, the back core sheet 103, and the back cover sheet 104 may be laminated with an adhesive interposed between the sheets, or may be laminated by thermal fusion. . When laminating with an adhesive, the number of sheets is reduced as much as possible because an adhesive coating is required. However, in the case of fusion, an adhesive core is not required, so the front core is located in the center. Each of the sheet 102 and the back core sheet 103 can be composed of a plurality of sheets with arbitrary thicknesses.
When the front surface pattern printing unit 11 is printed between the front cover sheet 101 and the front core sheet 102, first, the condensing fluorescent dye printing layer 12 is printed on the front core sheet 102, and the condensing fluorescent light is printed. The surface design printing unit 11 is printed on the surface of the dye printing layer 12.
When the printing apparatus is compatible with a thick sheet, the front core sheet 102 and the back core sheet 103 may be integrated into a single core sheet.

With reference to FIG. 3, another example of a cross section taken along line AA of FIG. 1 will be described.
The example shown in FIG. 3 is an example of a card whose card base is made of a single transparent resin material.
A condensing fluorescent dye printing portion 12 is formed on one surface of the card substrate with a printing ink containing the condensing fluorescent dye, and is not shown in the periphery of the condensing fluorescent dye printing portion. A strip-shaped printing blank area having a width of 0 mm, more preferably, a width of 0.5 mm to 4.0 mm is formed. When the card base is composed of a single transparent resin material, unlike the case of a plurality of sheets described with reference to FIG. As described above, it can be set narrowly.
In addition, the pattern printing unit 11 is formed on the surface of the condensing fluorescent dye printing unit, the outermost surface on the front side of the card is covered with the protective layer 21, and the outermost surface on the back side of the card is covered with the protective layer 22 like the surface.
Although not shown, the front and back surfaces of the card base 105 are subjected to an easy adhesion treatment so that printing ink containing a condensing fluorescent dye, printing ink for pattern printing, and paints for the protective layers 21 and 22 are easily adhered. There is also.

With reference to FIG. 4, an example of a mechanism for emitting light absorbed from the light-collecting fluorescent dye printing unit to the side surface of the card will be described.
FIG. 4 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 light-collecting fluorescent dye printing unit 12 follows the course indicated by the solid line, reflects the upper and lower surfaces of the core sheet 102, and reaches the side surface of the front core sheet 102. And released.
Further, the “b light” incident in the direction of the arrow from the surface of the light-collecting fluorescent dye printing unit 12 follows the course indicated by the dotted line, reflects the upper and lower surfaces of the front core sheet 102, and the front core sheet 102. Will reach the side of and be released.
Similarly, “c light” follows the course indicated by the one-dot broken line, reflects the upper and lower surfaces of the core sheet 102, 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.

As described above, even if a strip-shaped printing blank area is provided on the periphery of the light-collecting fluorescent dye printing portion, a card that is inferior to the case where no printing blank area is provided can be obtained.
In order to increase the degree of freedom of card design, it is preferable that a printing blank area can be formed wider. However, since a card in circulation has a short side of 54 mm and a long side of about 86 mm, it is wider than a width of 7.0 mm. When formed, the presence of a blank portion becomes conspicuous with respect to the size of the entire card. Therefore, if the width of the printing blank area is 7.0 mm or less, more preferably 4.0 mm or less, it is practically used.
On the other hand, if the lower limit is less than 0.5 mm, higher card extraction accuracy is required, which affects the cost.
The card thickness also seems to affect the width of the print blank area. When the card thickness is reduced, the card edge shines more effectively when the width of the print blank area is narrower.
A card whose card base is composed of a single resin material is applied to a card having a card thickness of 0.19 mm to 0.50 mm, and a card whose card base is composed of a plurality of resin materials. The card thickness is applied to a card used at the ISO standard of 0.76 mm.

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

With reference to FIG. 5, an example of the characteristic of the condensing fluorescent dye which converts the absorbed light into light having a different frequency and emits it will be described.
The example shown in FIG. 5 shows an example of an absorption spectrum and an emission (excitation) spectrum of a condensing fluorescent dye using “LumogenF Red305” manufactured by BASF.
“LumogenF Red305” indicates that the maximum absorption wavelength is 578 nm and the maximum emission wavelength is 613 nm.
In other words, when light from a light source with a frequency of 578 nm is irradiated onto a light-collecting fluorescent dye printing section using “Lumogen F Red305”, it absorbs the light “without waste” and emits light with a frequency of 613 nm 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 120 to 150 ° C. during the lamination of the card and a lamination time of about 40 minutes.
Furthermore, in order to maintain a characteristic of 95% or more even after continuous irradiation of 2000 hours of xenon lamp (having light resistance), the above-described absorption / release characteristics of the condensing fluorescent dye are practical even if the card is used for a long time. Can be maintained in range.

  In addition to the light-collecting fluorescent dye shown in FIG. 5, a dye having a maximum absorption wavelength of 476 nm and a maximum emission wavelength of 490 nm, a dye having a maximum absorption wavelength of 524 nm and a maximum emission wavelength of 539 nm, and a maximum absorption wavelength of 378 nm and a maximum emission wavelength There is a dye having a maximum absorption wavelength of 377 nm and a maximum emission wavelength of 411 nm, all of which have heat resistance and light resistance equivalent to “Lumogen F Red305”.

With reference to FIG. 1 and FIG. 2, the usage method and characteristics of the card of the present invention will be described.
The surface of 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 transmits the light transmitted through the front surface symbol printing unit 11 or the back surface symbol printing unit 13 or passes through the gap, and the condensed fluorescent dye printing layer 12 absorbs the irradiated light. Then, light having a frequency corresponding to the type of the condensing fluorescent dye is emitted from the side surface of the card 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.
