Description

[Detailed Description of the Invention] The present invention relates to a laminated card in which a recess or window is provided in a FIJ'J certificate, etc., and a card base material in which a photograph, etc. is inserted is laminated back with a plastic film on both sides. This is intended to prevent the outline of the photo-inserted portion from appearing on the back of the card, which would reduce the product value.

Conventionally, in the case of cards in which a photograph is pasted on the front surface and then laminated and packed on both sides with plastic film, the outline of the photograph pasted on the front surface becomes visible on the back side of the card because it is heated and pressurized during manufacture. This is a problem that not only significantly impairs the aesthetic appearance but also reduces the value of the product, and this tendency is especially noticeable when company marks or emblems are printed on the back of the card. .

Therefore, recently, four parts or windows corresponding to the size and thickness of the photograph are formed on the surface of a flat card base material, the photograph is inserted into these recesses or windows, and if necessary, backing paper is added. However, it is extremely difficult and impractical to perfectly match the area of the recess or window made in the card base material with the size of the photo. The thickness of the photo is usually between 170μ and 240μ, and it is extremely complicated and difficult to form a recess or window to match the thickness of the photo. Furthermore, it is common for the layer thicknesses of the photo-fitting portion and the other portions of the card to not match.

For this purpose, when a backing paper is laminated on the back side of the card base material, a plastic film is polymerized on both the front and back sides, and this is heated and pressurized to laminate and pack. Also, it has been considered that it is unavoidable to some extent that the outline of the window portion appears on the back of the card.

The inventors of the present invention have focused on this point, and have designed a method to completely prevent the outline of the photo from appearing on the back side of a laminated card with a photo inserted therein. A metal foil with good thermal conductivity or a plastic sheet with good heat resistance is polymerized on the back side of a card base material in which a photo or the like is inserted into the four parts or window parts that can be fitted with After polymerizing a plastic film, the film is laminated under heat.

The specific content of the present invention will be explained below based on the illustrated embodiment. In the embodiment shown in FIG. Show the photo. Photo 1 should be approximately the same size as card base month 1, or less. Furthermore, 3 indicates a card (the back side of the card 1), a polymerized metal foil, and 4 indicates a backing paper. After overlapping plastic films 6.6 on both sides of these cards, they are heated and pressed together to form a laminate pack. do.

In the above embodiment, when the blast tink film 6.6 is attached to the card and laminated and packed, there is no interference between the card holder 1 and the backing paper 4 even when heated and pressurized. The metal foil 3 has extremely excellent thermal conductivity, and when heated and pressurized, it can suitably diffuse the heat and pressure concentrated around the periphery of the inserted photograph, etc., the recessed part, or the periphery of the window part. As a result, it is possible to completely prevent the outline of photo 2 from appearing on the back of the card.

In this case, the thickness of the metal foil improves the wedge effect, but if the elastic force of the card after lamination pack is lost to the plastic force of the metal foil, it will have a negative effect on the properties of the card. It is necessary to determine the thickness of the metal foil after various considerations within the allowable range of the total thickness of the elastic force of the film and the elastic force of the core material.

In addition, in the embodiment shown in FIG. 2, not only the metal foil 3 but also a plastic sheet 5 having good heat resistance is polymerized and interposed between the card base material 1 and the backing paper 4. Specific examples of plastic sheets used in this case include polyester, polycarbonate, acrylic, and the like. Furthermore, in this case, the intervening position of the plastic sheet 5 and the metal foil 3 is preferably the order of the plastic sheet 5 and the metal foil 3 from the back side. Then, plastic sheet 5
This allows the effects of heat to be further diffused and the effects of pressure to be absorbed and diffused, making it possible to more effectively prevent the outline of the photograph from appearing on the back of the completed card.

In any of the above embodiments, when applied to a card whose total thickness must be limited to a range of 0.75 mm±o, 0.5 ms,
Our research has revealed that it is sufficiently effective.

The reason is that the thickness of the photo is usually in the range of 170μ to 240μ, so the remaining thickness of the entire card is only 510μ, and within this range it is impossible to prevent the outline of the photo from appearing on the back of the card. This is because it is extremely difficult.

As an example, when trying to hold a laminated card with a photograph inserted in it at a thickness equivalent to that of a known magnetic card (0.76mJ0.4tn), the card base material 1 is
40μ, layer thickness of metal foil 3 and backing paper 4, or plastic sheet 5 added to this, 220μ, plus deck film 6.60 layers for rough laminating cards is 1
A configuration of 50μ×2 is most preferable.

In addition, when a plastic sheet 5 is additionally interposed as in the embodiment shown in FIG. 2, the thickness of the metal foil 3 is usually in the range of 30μ to 150μ. When the sheet 5 is additionally interposed, good results can be obtained by using a polyester sheet with a thickness of 100 to 150 microns as the plastic sheet 5, and further polymerizing aluminum foil with a thickness of 30 to 70 microns.

As is clear from the description of each of the above-mentioned embodiments, the present invention can be used to obtain a laminated card with a photograph inserted therein, even if both sides are heated and pressurized, heating and pressurization can be performed by interposing a metal foil with good thermal conductivity. In order to appropriately diffuse the heat and pressure that is sometimes concentrated around the periphery of the inserted photograph, etc., or the periphery of the recess or window, it is possible to reliably prevent the outline of the photograph from appearing on the back of the card, and If a plastic sheet with good heat resistance is used in combination with this, the metal foil is used to diffuse the heat effect when heating and pressurizing when laminating the card, and then the plastic sheet is used to further diffuse the heat effect and the heat is applied. As a result of absorbing and diffusing the influence of pressure, it is possible to more reliably prevent the appearance of the outline of the photo on the back of the card, and as a result, it is possible to obtain a laminated card that has a good appearance and a good POP effect. . Although photographs are used as examples in explaining the present invention, objects to be inserted into cards are not limited to photographs, and objects with similar shapes such as barcode chips, integrated circuits, etc. The same effect can be achieved in this case.

Incidentally, there is no problem in applying a magnetic stripe to the laminated card of the present invention.
