Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) In the present invention, a transparent halftone dot-like colored display is provided on a transparent portion of a card such as a credit card, a member's card or a prepaid card by a hot stamp method. The present invention relates to a card manufacturing method.

(Prior Art) Conventionally, a card in which a transparent card base material is colored is
When viewed from one side of the card substrate, the colored display on the other side is observed, and the colored layers displayed on the front side and the back side of the card are observed from opposite sides so that they face each other. As a result, the colored display portions displayed on the surface of the card base material overlap and the display effect is impaired, making it difficult to see.

(Purpose of the Invention) The present invention is capable of observing a transparent portion of a resin card such that different patterns and characters such as letters are displayed on the front and back sides without overlapping each other, and the patterns and the like are observed separately on the front and back sides. In addition, it is an object of the present invention to manufacture a colored display card in which the colored display portion has transparency.

(Structure of the Invention) The present invention provides a release layer, and optionally a transparent protective layer, a first colored layer, a base colored layer, a second colored layer, and an adhesive layer, if necessary, on a transfer sheet substrate. A transfer sheet forming step of stacking in this order, a transfer painting step of superimposing a transfer sheet on a transparent oversheet for a card substrate, and a transfer pattern painting of a colored layer with a dot pattern by a hot stamp method, and an opaque center core sheet material A core core sheet forming step of fitting a transparent center core sheet material into the hole forming portion and a transparent center core sheet material in the hole forming portion; and a transfer painting oversheet on one side surface of the center core sheet, It is a method for manufacturing a colored display card, which comprises a sticking step of stacking and sticking a transparent oversheet on a side surface.

(Effect of the Invention) According to the present invention, it is possible to easily manufacture a card in which dots, pictures, and symbols are colored and displayed on the transparent portion of the card base material. A colored layer such as a picture or a letter is provided on the card, so that each picture and letter displayed on the front side and the back side of the card after transfer can be observed separately and are not overlapped.
Further, since the colored layer is applied in a dot shape, the entire colored display portion has transparency.

(Example) The method of the present invention will be described in detail according to an example. FIG. 1 is an explanatory view of the manufacturing process of the transfer sheet A, in which silicon, a release varnish, or the like is applied to the transfer base material 1 such as paper or polyester, acrylic, or polyvinyl chloride, or the polyester, acrylic, or polychlorinated material. After applying a release layer 2 formed by a release agent mixed with a resin such as vinyl, a transparent protective layer 3 such as polyester is applied, and then,
The first colored layer 4 of a line drawing and a gradation reproduction image of an appropriate number of colors is formed by a printing method. Then, one or two base colored layers 5 having an appropriate color, which also serve as a concealing layer, are superposed and laminated on the colored layer 4. Next, after forming a second colored layer 6 of a line number and gradation reproduction image of an appropriate number on the base colored layer 5 by a method, a transfer adhesive layer 7 is applied. The adhesive layer 7 is selected to have good adhesiveness to the material to be transferred. Next, the second

On the other hand, as shown in FIG. 4, a hole 9a is partially formed in the center core sheet material 9 such as white opaque polyvinyl chloride for card base material, and transparent polyvinyl chloride or the like is formed in the hole. The center core sheet material 8 is closely fitted so as to be flush with the sheet material 9 to prepare a center core sheet B for a card. Next, in FIG. 5, on the front and back of the center core sheet B, the transparent center core sheet 8
The pattern colored display oversheet 10 and the transparent oversheet 11 are superposed on each other via a heat-melting type adhesive so that the pattern colored layer a is positioned on the sheet, and the sheet is pressed by a flat pressure press to be adhered. To produce a colored display card in.

FIG. 6 is another embodiment of the method of the present invention, in which the transparent center core sheet material 8 side of the center core sheet B is
A colored display card is manufactured by stacking the colored layer a side of the colored display oversheet 10 and adhering the same as above. In the present invention, the opaque center core sheet material 9 as a card base material is not limited to white, and is an opaque sheet colored in an appropriate color.
In addition, it is possible to prevent a normal print indication from being given to an appropriate portion on the front surface or the back surface of the oversheets 10 and 11.

(Effect of the invention) The card obtained by the method of the present invention is provided with a transparent part in a part of the card, and a colored layer having a dot pattern is provided in the transparent part, and the part without the colored layer is abutted to the back of the car. The first colored layer can be seen from the front side of the card, and the second colored layer can be seen from the back side of the card, and the colored layers can be seen without overlapping. The method of the present invention makes it possible to manufacture such a card very easily.
