A magnetic card comprising a message print layer for displaying and displaying characters and pictures of the message print layer when the metal deposition layer is destroyed.

According to the present invention, a magnetic recording layer is formed on a part or the whole surface of a base material, a printing layer is formed on the back surface of the magnetic recording layer, and a top surface of the magnetic recording layer. In a magnetic card formed by sequentially laminating a thin metal vapor deposition layer and a resin protective film on the upper surface of the metal vapor deposition layer, the printing layer is a message printing layer for printing characters or pictures, or characters and pictures, etc. The magnetic card is characterized in that a thin metal vapor deposition layer is formed on the upper surface of the printed layer, and a resin protective film is sequentially laminated on the upper surface of the metal vapor deposition layer.

[0008]

Function: A message printing layer on which characters or pictures are printed is formed on the printing layer printed on the magnetic recording medium coating surface or the base material surface, and the characters or pictures are colored pigments such as white, red and yellow. On the upper surface of the message printed layer that is drawn with, form a metal vapor deposition layer of aluminum, tin, etc. of a thickness that can be destroyed by discharge or heat, and remove the metal vapor deposition layer by discharge or heat when using a magnetic card. Then, the message printed layer on the lower surface of the metal vapor deposition layer is exposed and the message formed by characters or pictures is known. The metal vapor deposition layer may be thick enough to conceal the colors and letters of the printed layer such as letters and pictures, and the thickness of the metal and aluminum (Al) in the case of discharge breakdown may be 1000 angstroms, or thermal breakdown. At this time, the thickness of tin (Sn) may be 1 micron. In addition, colored characters such as characters or pictures to be printed on the magnetic recording surface, or pictures are ordinary pigments,
A liquid resin obtained by dissolving polyethylene terephthalate, which is the same material as the base material, in a solvent is kneaded and used.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows a cross-sectional structure of a magnetic card according to a first embodiment of the present invention. In FIG. 1, a base material 1 is a polyethylene terephthalate (PET) film, a magnetic recording medium is applied onto the base material to form a magnetic recording layer 2, and a liquid resin and a pigment in which polyethylene terephthalate is dissolved in a solvent are formed on the magnetic recording layer 2. A message such as characters and pictures is printed using the pigments of the respective colors kneaded with to form the message print layer 6. Further, in order to conceal characters and pictures formed on the message print layer, tin (Sn) having a thickness of about 1 micron or aluminum (Al) having a thickness of 1000 Å to 5000 Å is provided on the surface of the message print layer. To form a metal vapor deposition layer 4,
A UV curable resin such as urethane or acryl is applied as a protective layer 5 thereon to obtain the magnetic card of the present invention. In the case of printing on the magnetic card of the present invention described above, when the metal vapor deposition layer 4 is aluminum, the metal vapor deposition layer 4 is destroyed by discharge breakdown, and when it is tin, the metal vapor deposition layer 4 is destroyed by heat. When the metal vapor deposition layer is destroyed, white or red or yellow letters or figures are displayed from the bottom of the metal vapor deposition layer, or when drawing letters or figures by discharge breakdown or thermal breakdown,
The color of the background becomes the color of letters, figures and pictures.

Therefore, during or after the use of the magnetic card, the message print layer appears by destroying the metal vapor deposition layer on the upper surface of the message print layer. For example, in a supermarket, when you use it as a magnetic card for shopping, when you use the magnetic card, the metal vapor deposition layer on the top of the message printing layer is destroyed, and if the word "hit" etc. appears, you can get the service etc. Or, colored advertisements can be made.

FIG. 2 is a sectional view of a magnetic card of a second embodiment according to the present invention. In this embodiment, a back surface of the conventional magnetic recording layer 2 of the first embodiment is used as a back surface. The print layer is used as the message print layer 6, and thin aluminum (Al) or tin (S) is formed on the upper surface of the message print layer.
It is an example of a magnetic card in which the metal vapor deposition layer 4 of n) and a protective layer 5 made of a resin for protecting the metal vapor deposition layer 4 are formed. The metal vapor deposition layer 4 and the protective layer 5 formed on the upper surface of the message printing layer 6 are It may be the same as in the first embodiment. Further, the metal vapor deposition layer 4 on the upper surface of the magnetic recording layer 2 of FIG. 2 shown in the second embodiment.
Is used for character printing similar to the conventional one, but a magnetic card provided with a printing layer 3 similar to the conventional one instead of the metal deposition layer 4 may be used.
