BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ID photo card using a thermal sublimation transfer print sheet.

0002

[Prior Art] Conventionally, ID photo cards have been made by laminating the front and back sides of a printed sheet with a protective plastic sheet on which the owner's affiliation, face photo, issuer's name, notes, etc. are printed. known and widely put into practical use. FIG. 7 shows an example of a known ID photo card.

FIG. 1A is a plan view showing the front side of this ID photo card viewed from above. In (A), 73 is a frame-shaped sheet. 74 is a frame sheet 73
It is a printed sheet inscribed and fixed to the cardholder, and specific information for the cardholder such as a face photo, name, affiliation, ID number, etc. is printed on the surface.

FIG. 2B is a sectional view taken along line bb in FIG. In (B), 71 is the plastic support of the ID photo card. Printed on the back side of the plastic support 71 are common items that are not specific to the cardholder, such as the issuer of the card and notes. A protective transparent back plastic sheet 72 is laminated on the back surface of the plastic support 71 via a hot-melt adhesive layer 76 . On the other hand, on the surface of the plastic support 71, a frame-shaped sheet 73 having a frame area slightly smaller than the size of the plastic support 71 is disposed via a hot-melt adhesive layer 77, and a frame-shaped sheet 73 is inscribed in the frame-shaped sheet 73. Print sheets 74 are stacked. The print sheet 74 has a size corresponding to the area surrounded by the frame sheet 73,
Moreover, it has approximately the same thickness as the frame-shaped sheet 73, and is firmly adhered and fixed to the frame-shaped sheet 73. Further, the printed sheets 74 have information specific to the card holder printed on their surfaces, and are stacked with the printed surfaces facing upward. A protective surface plastic sheet 75 is laminated on the frame sheet 73 and the printed sheet 74 via a hot-melt adhesive layer 78. Since the front plastic sheet 75 is a transparent sheet, when the ID photo card having the above structure is viewed from above, the state is as shown in FIG. 7(A).

[0005] A known ID having the structure shown in FIG. 7 above
Photo cards are generally made into cards as follows. That is, first, it is formed as a laminate having the above structure,
This laminate is passed between heat rolls. thus,
The hot-melt adhesive layers 76, 77, and 78 are heated and melted, the back plastic sheet 72 and the front plastic sheet 75 are laminated, and each layer is bonded to form a card. For the hot-melt adhesive layers 76, 77, and 78, general hot-melt adhesives such as ethylene-ethyl acrylate copolymer and ethylene-vinyl acetate copolymer may be used.

Furthermore, the ID photo card shown in FIG. 7 can also be subjected to mechanical processing, such as magnetic striping or the like, on the back plastic sheet 72 and the front plastic sheet 75.

FIG. 8 shows a modification of the known ID photo card shown in FIG. 7, in which the structures of the frame sheet 73 and print sheet 74 are different. Note that each reference symbol in the figure has the same meaning as in FIG. 7.

FIG. 2A is a plan view showing the front side of this ID photo card viewed from above. In (A), 83 is a frame-shaped printed sheet, on the surface of which specific information for the cardholder such as name, affiliation, ID number, etc. is printed. 84 is photographic paper, and frame-shaped print sheet 8
It is fixed inscribed in 4 and has a photograph of the cardholder's face printed on it.

(B) of the same figure shows the ID along the c-c line of (A).
FIG. 3 is a cross-sectional view of a photo card. In (B), a frame-shaped print sheet 83 having a frame area slightly smaller than the size of the plastic support 71 is placed on the plastic support 71 via a hot-melt adhesive layer 77, and Inscribed photographic paper 74 is laminated. The frame-shaped printed sheets 83 have information specific to the card holder printed on their surfaces, excluding a facial photograph, and are stacked with the printed surfaces facing upward. The photographic paper 84 is a photograph of the cardholder's face on film and printed on general instant photographic paper, color photographic paper, or the like. The photographic paper 84 is a frame-shaped print sheet 8
It is cut to a size corresponding to the area surrounded by 3, and is firmly adhered and fixed to the frame-shaped sheet 83. As mentioned above, in the ID photo card shown in FIG.
The frame-shaped printed sheet 83 is the frame sheet 73 in FIG.
and some of the functions of the print sheet 74. Further, an ID photo card having a structure as shown in FIG. 8 can also be processed into a card, magnetically striped, etc. in the same manner as described above.

[0010] In recent years, in the above-mentioned well-known ID photo cards, a print sheet layer, for example, a print sheet 74 in FIG. In FIG. 8, it is proposed to use a print sheet produced by a thermal sublimation transfer printer as the frame-shaped print sheet 83 and photographic paper 84.

[0011] Such a print sheet is created by photographing the ID card holder with a video camera and displaying the photographed portion, information specific to the card holder such as name, affiliation, ID number, and other design patterns. Compose and edit,
It was created using a heat sublimation transfer video printer. More specifically, an image is formed by image signal processing, dye is transferred onto image-receiving paper by thermal diffusion, and a dye image with the above items described is printed. With this heat sublimation transfer method, it is very easy to print the face photo part of an ID photo card.
Furthermore, since image formation is performed through image signal processing, high-quality print sheets can always be stably obtained. Therefore, the print sheet obtained by this method is expected to be suitable for use as a print sheet for ID photo cards.

However, when a print sheet made by the thermal sublimation transfer method is used for an ID photo card, the dye on the image is easily diffused by heat, so it may spread to other layers due to the influence of heating during the card forming operation. May spread and migrate. For example, the thermal sublimation transfer print sheet can be used as the print sheet 74 in the ID photo card illustrated in FIG. 7, or the frame-shaped print sheet 83 and photographic paper 8 in the ID photo card illustrated in FIG.
4, and when an ID photo card is created by heating lamination using a heat roll as described above, the dye image on the surface of the print sheet will adhere to the upper surface plastic sheet 75 over time due to the effect of heating. The hot-melt adhesive layer 78 oozes out. For this reason, an ID photo card having a print sheet created by a thermal sublimation transfer method cannot retain an image on which each item is written for a long period of time, and there is a limit to the period of use of the card.

[0013]

[Problems to be Solved by the Invention] The present invention has been made in view of the above problems, and its object is to
When using a print sheet with an image formed by a thermal sublimation transfer printer for a D photo card, the dye image may bleed over time into the upper layer, especially the hot-melt adhesive layer that adheres the surface protection sheet. The objective is to prevent this and maintain good images for a long period of time.

[0014]

[Means for Solving the Problems] The ID photo card of the present invention includes a support, a back cover sheet formed on the back of the support via a first hot-melt adhesive layer, and a back cover sheet formed on the back of the support. A frame-shaped sheet laminated on the surface via a second heat-melting adhesive layer, and a dye image formed on the surface by a heat sublimation transfer printer, and corresponds to an area surrounded by the frame-shaped sheet. a print sheet having a size of A print sheet laminated via a two-heat melt adhesive layer, a dye diffusion prevention layer laminated on the dye image surface of the print sheet, and a dye diffusion prevention layer laminated on the dye diffusion prevention layer and on the frame sheet. It is characterized by comprising a surface cover sheet laminated with a third hot-melt adhesive layer interposed therebetween.

[0015] In the ID photo card of the present invention, the dye diffusion prevention layer is formed simultaneously with the dye image by the same process in which the dye image is formed on the print sheet by a thermal sublimation transfer printer. Preferably.

[0016] Furthermore, in the ID photo card of the present invention, the material of each adhesive is different between the portion of the third heat-melting adhesive layer that covers the dye diffusion prevention layer and the portion that covers the frame sheet. Preferably, the dye diffusion preventing layer and the third hot-melt adhesive layer on the dye diffusion preventing layer are combined as a single layer.

[0017]

[Function] In the ID photo card of the present invention, dye diffusion occurs between the dye image on the print sheet formed by a heat sublimation transfer printer and the third heat-melting adhesive layer for bonding the front cover sheet. The prevention layer prevents the dye image from seeping into the third hot-melt adhesive layer over time due to the influence of heating during the carding operation. In this way, the quality of the dye image on the ID photo card can be maintained well for a long period of time.

Furthermore, in the ID photo card of the present invention, since the dye diffusion preventing layer is formed in the same process and at the same time as the dye image is formed on the print sheet, its formation is very easy. be able to.

Furthermore, in the ID photo card of the present invention, the dye diffusion preventing layer and the third heat-melting adhesive layer on the dye diffusion preventing layer are used as a single layer, and the heat-melting adhesive layer is a single layer. The adhesion ability and dye diffusion prevention ability have been synthesized. This further prevents the dye image from seeping into the third hot-melt adhesive layer.

The first, second and third hot melt adhesive layers 17, 18 and 19 also contain ethylene-ethyl acrylate, similar to the hot melt adhesive layers in the conventional ID photo card. Common hot melt adhesives such as polymers, ethylene-vinyl acetate copolymers, etc. can be used.

The ID photo card of the first embodiment of the present invention having the above structure is first formed as a laminate having the above structure, and then this laminate is passed between heat rolls, as in the conventional ID photo card. By doing so, it becomes a card.

According to the first embodiment, between the dye image surface of the print sheet 14 produced by a heat sublimation transfer printer and the third heat-melting adhesive layer 19 that adheres the front cover sheet 16, The presence of the dye diffusion prevention layer 15 prevents the dye image from seeping into the third hot-melt adhesive layer 19, which occurs over time due to the influence of heating during carding. Next, an example of processing the ID photo card of the first embodiment will be explained with reference to FIGS. 2 and 3.

FIGS. 2A to 2C show the print sheet 14 in the ID photo card of the first embodiment shown in FIG.
FIG. 4 is a diagram illustrating an example of a process for creating a dye diffusion preventing layer 15 laminated on the dye image.

In the same figure (A), 21 is a print sheet matrix created by a thermal sublimation transfer printer, and the dye image of multiple print sheets (2 print sheets are shown in the figure, 141, 141'
...Cardholder photo area, 142,142'...I

Next, as shown in FIG. 2C, the print sheet matrix 21 is cut into a predetermined size using a punching device to form sheets 24 (and 24'). The sheet 24 is a laminate of the print sheet 14 and the dye diffusion prevention layer 15 made of the dye non-migration adhesive layer 151 and the transparent plastic layer 152 in the ID photo card of Example 1 shown in FIG. 1(B). It becomes. FIG. 3 is a diagram showing an example of the state of the ID photo card of the first embodiment.

As shown in the figure, each layer constituting the ID photo card of the first embodiment is stacked by thermally welding only one end of each layer. Here, in the area 31 surrounded by the frame sheet 13, sheets 2 are laminated as explained in FIG.
4, the print sheet 14 has a second hot-melt adhesive layer 18
Insert it so that it is inscribed on the side. Next, the laminate in which the sheet 24 is fitted is processed using a heat roll or a press laminator to adhere each layer to form a card. In this way, the ID photo card of the first embodiment is formed. FIG. 4 is a sectional view of an ID photo card according to a second embodiment of the present invention.

As shown in the figure, the ID photo card of the second embodiment has almost the same cross-sectional structure as the first embodiment shown in FIG. The structure differs in that a dye diffusion prevention treated layer 41 is laminated. That is, the dye diffusion prevention layer 41 is a single resin layer, and differs from the first embodiment in that it does not include a transparent plastic layer 152 like the first embodiment shown in FIG. 1(A). The ID photo card of the second embodiment of the present invention having the above structure can also be made into a card in the same manner as the conventional ID photo card.

Also in the second embodiment, due to the presence of the dye diffusion preventing layer 41, similar to the ID photo card of the first embodiment, the printed sheet is generated over time due to the influence of heating during card formation. The dye image No. 14 is prevented from seeping into the third hot-melt adhesive layer 19.

Regarding the ID photo card of the second embodiment shown in FIG.
can be formed simultaneously by the same process by a thermal dye sublimation transfer printer. Below, Figure 5
Accordingly, the process of forming the dye image and the dye diffusion prevention layer in the ID photo card of the second embodiment will be explained.

FIG. 2A is a structural diagram of a thermal sublimation transfer printer that forms the dye image and transfers and coats the dye diffusion prevention layer. In the figure, reference numeral 51 denotes a photographic paper serving as a print sheet, whose surface (image-receiving layer side) is coated with a dye-receiving layer, and is reciprocated by a platen roller 53 in the direction of the arrow and in the opposite direction. 52 is an ink sheet whose surface (dye layer side) is coated with a dye to be transferred to the photographic paper 51 and a dye diffusion prevention resin;
4 as the feeding side, and the ink sheet winding roll 55 as the winding side, the ink sheet is fed in the direction of the arrow. Reference numeral 56 denotes a thermal print head, which transmits an image signal in which the face photo and other items on the ID photo card are synthesized and edited. The image-receiving layer side of the photographic paper 51 and the dye layer side of the ink sheet 52 are sandwiched and contacted by a platen roller 53 and a thermal print head 56 in a transfer section 57. In the transfer section 57, the dye image is transferred from the ink sheet 52 to the photographic paper 51.

FIG. 5B is a diagram showing the structure of the dye layer side of the ink sheet 52 used in the printer of FIG. In the same figure, 521 is a cyan dye application area;
22 is a magenta dye coating area, 523 is a yellow dye coating area, and 524 is a thermal transferable dye diffusion prevention resin coating area, and each area is arranged in the longitudinal direction of the ink sheet 52 in this order. As this thermally transferable dye diffusion preventing resin, resins and waxes of the same kind and type as those used in the non-dye migration adhesive layer of the ID photo card of the first embodiment may be used.

In FIG. 5A, first, photographic paper 51 and ink sheet 52 are fed in the direction of the arrow. The tip of the cyan dye application area 521 of the ink sheet 52 is the transfer portion 5
2, an image signal is sent to the thermal print head 56. In response to this image signal, heat is transferred from the thermal print head 56 to the cyan dye application area 521 of the ink sheet 52, and as the photographic paper 51 and ink sheet 52 are gradually fed in the direction of the arrow, the cyan dye is applied. The cyan dye on the area 521 moves to the image-receiving layer side of the photographic paper 51 by thermal diffusion. After cyan printing is completed, the ink sheet 52 is further fed in the direction of the arrow, and the leading edge of the next magenta dye application area 522 reaches the transfer section 52. During this time, the photographic paper 51 is fed back to the starting position, ie, the position where the cyan dye transfer is started. Thereafter, similar to the cyan dye described above, the magenta dye on the magenta dye application area 522 of the ink sheet 52 moves to the image receiving layer side of the photographic paper 51 by thermal diffusion. Subsequently, following the same process, the yellow dye application area 523 of the ink sheet 52 is
The upper yellow dye moves to the image-receiving layer side of the photographic paper 51 by thermal diffusion. In this way, the desired dye image is formed on the photographic paper 51.

After forming the dye image as described above, the ink sheet 52 is further fed in the direction of the arrow until the leading edge of the next thermally transferable dye diffusion prevention resin coating area 524 reaches the transfer section 52. During this time, the photographic paper 51 is fed back to the starting position, ie, the position where the formation of the dye image has begun. next,
An image signal (signal unrelated to the dye image) similar to that used when forming a solid image is sent to the thermal print head 56. In response to this image signal, heat is transferred from the thermal print head 56 to the thermally transferable dye diffusion prevention resin coating area 524 of the ink sheet 52. In this way, the thermally transferable dye diffusion prevention resin is melt-transferred to the entire surface of the dye image formed on the photographic paper 51, and a dye diffusion prevention processing layer is laminated on the surface of the dye image on the photographic paper 51.

By continuously performing the above-described process, the dye image on the print sheet 14 and the dye diffusion prevention processing layer 41 laminated on the dye image in the ID photo card of the second embodiment are formed. are formed at the same time. FIG. 6 is a sectional view of an ID photo card according to a third embodiment of the present invention. As shown in the figure, the ID of the third embodiment
The photocard has almost the same cross-sectional structure as the first embodiment shown in FIG. 1(A), but differs in the following points.

First, a dye diffusion preventing layer 61 having a single layer structure and having heat-melting adhesive properties is laminated on the dye image of the print sheet 14. The dye diffusion prevention layer 61 is
Although it is a resin layer like the dye diffusion prevention layer 41 shown in FIG. 4 of the second embodiment, it also has a surface cover sheet 16.
It has adhesive ability to adhere. That is, the dye diffusion prevention layer 61 is a combination of the dye diffusion prevention layer in the first and second embodiments and the third hot-melt adhesive layer laminated on the dye diffusion prevention layer. It is used in both layers and has the functions of both layers. However, the material used for the dye diffusion prevention layer 61 is different from the adhesive used for the third hot-melt adhesive layer in the first and second embodiments.

[0045] Also, in order to adhere the surface cover sheet 16 only on the frame sheet 13, a third heat-melting adhesive layer 6 is applied.
2 are stacked. The third hot-melt adhesive layer 62 in this embodiment is the same as the third hot-melt adhesive layer in the first and second embodiments, but is made of a material different from that of the dye diffusion prevention layer 61. Adhesives may be used. The ID photo card of the third embodiment of the present invention having the above structure can also be made into a card in the same manner as the conventional ID photo card.

In the third embodiment as well, due to the presence of the dye diffusion preventing layer 61, the print sheet is generated over time due to the influence of heating during card formation, similar to the ID photo card of the first embodiment. Bleeding of the dye image on the 14 surface is prevented. Furthermore, in the first and second embodiments, there is a possibility that the coating and lamination of the dye diffusion prevention layer on the dye image may be incomplete depending on the material, and in this case, the effect on preventing the dye image from bleeding out may be decreases. However, in the third embodiment described above, this problem is solved and bleeding of the dye image is further prevented.

In the ID photo card of the third embodiment, it is preferable that the side of the front cover sheet 16 in contact with the dye diffusion prevention layer 61 is subjected to a primer treatment or the like in advance to improve adhesion.

[0048]

Effects of the Invention As described in detail above, the ID photo card of the present invention is characterized in that the dye image formed on the print sheet by a heat sublimation transfer printer adheres to the upper layer, especially the surface protection sheet. This has a remarkable effect on preventing seepage into the mold adhesive layer and maintaining good images over a long period of time.
