Description

[0001]
[Industrial applications]
The present invention relates to a card in which a center core and an oversheet are adhered with a print layer interposed, and a method for producing the card.
[0002]
[Prior art]
As shown in FIG. 5, this type of conventional card generally has a printed layer 101 provided except for the four peripheral edges of the center core 100, and an oversheet 103 is adhered via an adhesive layer 102. It is a target. This configuration is adopted in order to secure the adhesion at the four peripheral edges because the center core 100 and the oversheet 103 do not adhere to each other at the portion where the print layer 101 is interposed.
[0003]
[Problems to be solved by the invention]
For this reason, in the related art, since the four edges of the card are white-rimmed, the appearance is poor and the printing area is reduced . Also in the past, in the case of coarse printing of the eye, such as silk printing, but the print layer 101 can be stuck to the center core 100 also entirely provided with the over sheet 103, multi-color printing In the case of fine-grained printing as described above, the two cannot be attached to each other, and there is an inconvenience that printing cannot be performed neatly in order to ensure a perfect attachment state. An object of the present invention is to provide a card that solves such a problem and a method for producing the card.
[0004]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the card of the present invention is provided with a printing layer on at least one surface of a center core via an adhesive layer, and an adhesive layer on a side of the printing layer opposite to the center core. Is provided with an overseat.
[0005]
Further, the method for producing a card according to the present invention includes the step of providing an adhesive layer on at least one surface of the center core, the adhesive layer surface of an oversheet having an adhesive layer provided on one surface, or the adhesive layer surface of the center core. A printing layer is provided by printing entirely on one surface, and the center core and the oversheet are attached to each other with the adhesive layer surfaces facing each other. The adhesive layer provided on the oversheet may be provided in advance, or may be provided at the stage of sticking to the center core.
[0006]
[Action]
An adhesive layer is provided on both sides of the printing layer, and the center core and the oversheet are attached.
[0007]
【Example】
Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to FIGS. Here, FIG. 1 is a plan view of the back side of the card, FIG. 2 is a schematic sectional view taken along line AA of FIG. 1, FIG. 3 is a plan view of the front side of the embossed card, and FIG. It is a flowchart which shows a process.
[0008]
As shown in FIGS. 1 and 2, the card 1 is made of various resins such as polyvinyl chloride, polyester, polypropylene, polystyrene, acrylic, and styrene. Heat-sensitive adhesives that can be bonded when a predetermined heat is applied, such as vinyl chloride, vinyl chloride, etc., or pressure-sensitive adhesives that can be bonded when a predetermined pressure, such as vinyl acetate or epoxy, is applied Layers 3 and 4 are provided, and printed layers 5 and 6 are provided on these adhesive layers 3 and 4, respectively. On the adhesive layers 7, 8, oversheets 9, 10 made of transparent vinyl chloride resin are provided, and on the backsheet 9, magnetic information enters. And it is configured to provide a magnetic stripe 11 that is.
[0009]
Next, a method for creating the above-described card 1 will be described. First, adhesive layers of the same kind selected from heat-sensitive or pressure-sensitive adhesives are applied to both surfaces of the center core 2 to form the adhesive layers 3 and 4. Printing is performed on the entire surface of each of the adhesive layers 3 and 4 to form printing layers 5 and 6. On the other hand, adhesive layers 7, 8 are formed on one surface of each of the oversheets 9, 10 in the same manner as the adhesive layers 3, 4. Then, a magnetic stripe 11 is formed on the side of the oversheet 9 opposite to the adhesive layer 7 by an appropriate method such as printing or bonding a magnetic tape. Subsequently, the center core 2 and the adhesive layers 3, 4 and 7, 8 of the oversheets 9, 10 are brought into contact with each other, and then the adhesive layers 3, 4, 7, 8 are bonded. A card 1 shown in FIGS. 1 and 2 is created by attaching conditions and attaching the card. Since this bonding is performed in a state where the adhesive layers 3, 4 and 7, 8 are present on both surfaces of the printing layers 5, 6, the center core 2 and the oversheets 9, 10 are securely bonded. Thereafter, as shown in FIG. 3, when predetermined information is displayed by embossing or the like, the card 1 is in a usable state.
[0010]
When embossing is performed as in this embodiment, the material of the center core 2 is preferably a vinyl chloride resin or polyethylene terephthalate. In addition, it is preferable that the center core 2, the adhesive layers 3, 4, 7, 8 and the oversheets 9, 10 are unified with the same kind of material. Particularly, the material of each component is made of vinyl chloride resin. Is most preferable.
[0011]
The present invention is not limited to the above-described embodiment. For example, the adhesive layers 3 and 4, the printing layers 5 and 6, the adhesive layers 7 and 8, and the oversheets 9 and 10 It may be provided only on one side. Further, on the oversheets 9 and 10, a process for ensuring writing properties, for example, a matting process, a pigment coating process, a paper chip bonding process, and the like can be performed. Further, the center core 2 may be configured in a laminated state including a plurality of layers. Furthermore, when forming the print layers 5 and 6, appropriate information such as barcode information can be simultaneously printed. Further, the print layers 5 and 6 may be formed not on the center core 2 side but on the oversheets 9 and 10 side and both may be adhered. The magnetic stripe 11 is provided depending on the use of the card 1, and need not always be provided.
[0012]
【The invention's effect】
As is clear from the above description, according to the present invention, since the center core and the oversheet are adhered to each other with the adhesive layer interposed on both surfaces of the printing layer, any type of printing can be performed over the entire surface. the center core and the over sheet and can be hardly peeled off is reliably stuck to, also look able maintain the colors and print is an effect that good.
