Description

  The present invention relates to a transfer method and a scratch card for transferring a transfer layer onto a concealing layer (hereinafter referred to as a scratch layer) that is removed by rubbing or the like.

Conventionally, this type of scratch card is used as a lottery card, a lottery ticket, a prepaid card, etc., and a scratch layer is provided to conceal the lottery result and individual information (for example, Patent Document 1, 2).
Some scratch cards have a hologram layer formed above the scratch layer in order to improve security.

FIG. 5 is an explanatory view showing a layer structure and a manufacturing process of a conventional scratch card. The scratch card 20-1 includes a base material 21, a print layer 22 on which individual information and the like are printed, a release layer 23, a scratch layer 24, and the like. The scratch layer 24 is a layer that conceals individual information and the like and can be scraped off by a coin or the like. The release layer 23 is a layer that enables the scratch layer 24 formed on the upper surface thereof to be peeled off.

Next, a transfer process for transferring the hologram layer to the scratch card 20-1 will be described.
First, on the upper side of the scratch card 20-1, a transfer sheet 15A wound at both ends in a web shape is arranged, and on the upper side, a platen 40 for pressing the transfer sheet 15A against the scratch card 20-1 is provided. Deploy. The transfer sheet 15A includes a transfer layer 15 on which a hologram layer is formed.
The platen 40 brings the transfer layer 15 into contact with the scratch card 20-1 by an appropriate lifting mechanism and presses the transfer layer 15 against the scratch layer 24. As a result, the transfer layer 15 is transferred to the scratch layer 24.
By this transfer step, the scratch card 20 on which the hologram layer is formed can be produced.

However, this transfer process has the following problems. (1) In order to accurately transfer the transfer layer 15 to the scratch layer 24, it is necessary to match the shape of the platen 40 with the shape of the scratch layer 24, and a dedicated platen 40 must be prepared for each scratch layer 24. did not become. For example, if the scratch layer 24 is a star shape, a star-shaped platen 40 is necessary.
(2) Since the platen 40 and the scratch layer 24 have the same shape, there is a problem in that transfer failure occurs unless the platen 40 is aligned with high accuracy. For example, if the position of the platen 40 is slightly shifted, the end 15B of the transfer layer 15 protrudes from the scratch layer 24, the end 15C of the transfer layer 15 is not transferred to the periphery of the scratch layer 24, etc. (See (b) in the figure).
In particular, the end 15 </ b> B of the transfer layer 15 may come into contact with the substrate 21 instead of the release layer 23 by being pressed against the platen 40. For this reason, when the scratch card 20 is rubbed with a coin or the like, the end 15B of the transfer layer 15 may remain as a shaving defect 15D on the substrate 21 (see (c) in the figure). .
(3) The peripheral edge of the platen 40 is easily affected by air for cooling the transfer layer 15 transferred to the scratch layer 24. For this reason, the temperature of the peripheral edge of the platen 40 is lower than that of other parts (for example, the central part), and the transfer layer 15 located at the peripheral edge of the platen 40 may be difficult to be transferred to the scratch layer 24.

In the transfer method of the present invention, (1) a release layer whose periphery is outside the periphery of the masking layer is formed on the upper side of the substrate, and a masking layer is formed on the top of the release layer, and the periphery is peeled off. Since the transfer layer was transferred to the concealment layer using the transfer base that was inside the periphery of the layer and outside the periphery of the concealment layer, the shape of the transfer base was changed to the shape of the concealment layer. There is no need to match.
Moreover, since the periphery of the transfer base is inside the periphery of the release layer, when the transfer layer is pressed against the concealing layer, the transfer layer located at the periphery of the transfer base contacts the release layer. Even if it does not contact a base material, it can prevent that a transfer layer will be transcribe | transferred on a base material.

(5) The scratch card manufactured by using the transfer method described above has the transfer layer and the masking layer having substantially the same peripheral edge. Therefore, when the scratch card is rubbed with a coin or the like, the transfer layer is It can prevent remaining as a shaving defect on a base material.

  The present invention aims to accurately transfer the transfer layer onto the hiding layer, and after forming the release layer so that the periphery is outside the periphery of the hiding layer, the periphery is more than the periphery of the release layer. This is achieved by pressing the transfer layer against the masking layer using a transfer base that is inside and outside the periphery of the masking layer.

Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a diagram schematically showing an embodiment of a scratch card according to the present invention.
The scratch card 10 is a card in which secret information is concealed, and is used as a lottery card, a lottery ticket, a speed lottery card, a communication-related prepaid card, or the like.
The scratch card 10 includes a card substrate 11, a print layer 12, a release layer 13, a scratch layer 14, a transfer layer 15, and the like.

  The card substrate 11 is a substrate serving as a carrier for the scratch card 10 and is disposed in the lowermost layer of the scratch card 10, for example, paper or plastic (polyethylene terephthalate (hereinafter referred to as PET), vinyl chloride) or the like. Is formed.

  The printing layer 12 is formed on the upper side of the card base 11 and appropriately confidential information (for example, whether or not a lottery is won, lottery number, individual information, serial number, variable number, character data, image, code, mark, etc. ) Is the printed layer.

  The release layer 13 is a layer for facilitating the scraping of the scratch layer 14, and is formed of, for example, a silicon-based release ink. Further, the peripheral edge of the release layer 13 has a circular shape surrounding the star-shaped scratch layer 14.

  The scratch layer 14 is a layer that can be scraped off with a coin or the like, and is provided so as to cover the print layer 12 in order to conceal the secret information printed on the print layer 12.

  The transfer layer 15 is a layer transferred from the transfer sheet 15A described later by the platen 30, and includes a release layer 15-1, a hologram layer 15-2, a vapor deposition layer 15-3, an adhesive layer 15-4, and the like. It has. The peripheral edge of the transfer layer 15 has a star shape and substantially coincides with the peripheral edge of the scratch layer 14.

FIG. 2 is a diagram schematically showing the transfer sheet 15A. The transfer sheet 15A includes a transfer layer 15, a sheet base material 15-5, and the like. As described above, the transfer layer 15 includes the release layer 15-1, the hologram layer 15-2, the vapor deposition layer 15-3, the adhesive layer 15-4, and the like.
The sheet base material 15-5 is provided on the upper side of the transfer layer 15, and protects the transfer layer 15 from damage due to external force and gives strength. For example, PET or the like is used.

The release layer 15-1 is a layer for enabling the transfer layer 15 to be easily peeled from the sheet base material 15-5.
The hologram layer 15-2 is a resin layer in which a two-dimensional or three-dimensional image that can be reproduced with white light is recorded as a hologram image (pattern). is there.
Further, the hologram layer 15-2 has a thin thickness of several μm (for example, 1 to 2 μm), and further, since it is an ultraviolet curable resin, it is hard and brittle and has so-called fragility.
The vapor deposition layer 15-3 is provided below the hologram layer 15-2, and is formed by forming a metal such as aluminum into a thin film.
The adhesive layer 15-4 is provided below the vapor deposition layer 15-3, and is made of a rubber-based adhesive, an acrylic-based adhesive, or the like.

FIG. 3 is an explanatory view showing the manufacturing process of the scratch card 10 according to the present embodiment. For convenience of explanation, a scratch card to which the transfer layer 15 has not been transferred is referred to as a scratch card 10-1.
FIG. 4 is a view schematically showing a scratch card 10-2 in which the transfer layer 15 and the scratch layer 14 are scraped from the scratch card 10. As shown in FIG.
First, the peeling layer 13 is formed on the upper side of the card substrate 11 on which the printing layer 12 is formed. The release layer 13 is formed so that the periphery thereof is outside the periphery of the scratch layer 14.
Next, the scratch layer 14 is formed on the release layer 13 so as to cover the print layer 12. The scratch layer 14 is formed to have a predetermined step (for example, 4 to 10 μm) with respect to the release layer 13. Moreover, if the periphery of the scratch layer 14 is inside the periphery of the peeling layer 13 and can cover the printing layer 12, it is not limited to a star shape as shown in FIG. There may be.

Next, on the upper side of the scratch card 10-1, a transfer sheet 15A wound at both ends in a web shape is disposed, and on the upper side, a pressure plate 30 for pressing the transfer sheet 15A against the scratch card 10-1. Place.
The platen 30 is positioned by a suitable alignment mechanism such that its peripheral edge is located inside the peripheral edge of the release layer 13 and outside the peripheral edge of the scratch layer 14. The position is adjusted.

  That is, the positioning of the platen 30 is not limited as long as the periphery of the platen 30 is positioned within the predetermined range described above, and the alignment mechanism need not be controlled with high accuracy. Further, if the platen 30 has such a size that its peripheral edge is located within a predetermined range, the shape of the platen 30 does not need to match the shape of the scratch layer 14.

Next, the platen 30 brings the transfer layer 15 into contact with the scratch card 10-1 and presses the transfer layer 15 against the scratch layer 14 by an appropriate lifting mechanism (see (b) in the figure).
Further, the platen 30 returns to the original position after pressing the transfer layer 15 against the scratch layer 14 (see (c) in the figure).
As a result, the scratch card 10 having the transfer layer 15 transferred onto the scratch layer 14 can be produced.

  Here, since the periphery of the platen 30 is inside the periphery of the release layer 13, when the transfer layer 15 is pressed against the scratch layer 14, the transfer layer 15 positioned at the periphery of the platen 30 is not separated from the release layer 13. The card substrate 11 is not contacted even if the card is touched. For this reason, it is possible to prevent the transfer layer 15 from being transferred onto the card substrate 11.

  Further, since the scratch layer 14 is formed to have a predetermined step with respect to the release layer 13 as described above, when the transfer layer 15 is pressed against the scratch layer 14 using the platen 30, the platen It is possible to prevent the transfer layer 15 located at the peripheral edge of 30 from coming into contact with the release layer 13.

  Even if the transfer layer 15 located on the periphery of the platen 30 is in contact with the release layer 13, the transfer layer 15 and the release layer 13 located on the periphery of the platen 30 are affected by the effect of the release ink of the release layer 13. The transfer layer 15 is not transferred to the release layer 13.

Further, since the periphery of the platen 30 is outside the periphery of the scratch layer 14, when the transfer layer 15 is pressed against the scratch layer 14 using the platen 30, the periphery of the scratch layer 14 is In contact with the transfer layer 15 located at a portion other than the periphery of the platen 30 (for example, the central portion) that is not easily affected by the air for cooling the transfer layer 15 without contacting the transfer layer 15 located at the periphery. Become.
Here, the temperature of the periphery of the platen 30 is lower than the portion other than the periphery of the platen 30 due to the influence of air. For this reason, the transfer layer 15 located on the periphery of the platen 30 is in a state where the adhesive force by the adhesive layer 15-4 is not sufficiently exhibited, and is difficult to be transferred to the scratch layer 14.
However, since the periphery of the scratch layer 14 is in contact with the transfer layer 15 located at a portion other than the periphery of the platen 30 as described above, a transfer failure of the transfer layer 15 occurs at the periphery of the scratch layer 14. There is no.

  Thus, according to the manufacturing process of the scratch card 10 described above, the transfer layer 15 on which the hologram layer 15-2 is formed can be accurately transferred onto the scratch layer 14 using the platen 30.

In addition, the scratch card 10 is scraped off from the transfer layer 15 and the scratch layer 14 with a coin or the like to become a scratch card 10-2 (see FIG. 4).
That is, the transfer layer 15 includes a peeling layer 15-1, a fragile hologram layer 15-2, a vapor deposition layer 15-3 in which a metal is formed into a thin film, and an adhesive layer 15- adhered to a scratchable scratch layer 14. 4 and so on, it is destroyed and scraped off together with the scratch layer 14 by a coin or the like.
Therefore, the hologram layer 15-2 does not remain as a shaving defect on the card substrate 11.

(Modification)
The present invention is not limited to the embodiments described above, and various modifications and changes are possible, and these are also within the equivalent scope of the present invention.
(1) The transfer layer 15 may be provided with a diffraction grating layer that causes light interference instead of the hologram layer 15-2. In this way, the transfer layer having the diffraction grating layer formed above the scratch layer 14 can be accurately transferred.
(2) The transfer layer 15 is not a hologram layer 15-2 or the diffraction grating layer described above, but a metal thin film layer (for example, a metal vapor-deposited foil such as a gold foil or a silver foil) in which a metal such as gold or silver is formed into a thin film. The release layer 15-1, the metal thin film layer, the adhesive layer 15-4, and the like may be laminated in this order from above on the lower side of the sheet base material 15-5.
In this way, the transfer layer having the metal thin film layer formed on the scratch layer 14 can be accurately transferred.
(3) The transfer layer 15 may further include a colored layer colored with a desired color (for example, gold) under the release layer 15-1.
(4) The transfer layer 15 may be formed of paper, a plastic film, or the like below the adhesive layer 15-4, and a release paper that protects the adhesive layer 15-4 until the transfer layer 15 is transferred may be attached.
