First, in the first step, the transparent sheet 160 having a pattern protrusion 165 having a predetermined pattern is formed on the upper protective sheet 110 of the card body part 100 configured as described above in a downward direction.

In this case, the transparent sheet 160 is preferably polyethylene terephthalate (polyethylene terephthalate), polycarbonate (polycarbonate), polyvinyl chloride (Polyvinyl chloride), ABS (acrylonitrile-butadiene-styrene resin) sheet and PMNA (Polymethyl) Any of poly (meth) acrylate) sheets may be used.

Next, the second step is temporarily temporary bonding the card body portion 100 and the transparent sheet 160, as shown in FIG. It is placed between the pressing plates 170 of the hot press to press the upper and lower at a predetermined temperature and pressure.

At this time, the temperature for heating the transparent sheet 160 formed with the temporarily bonded guard body portion 100 and the pattern pattern protrusion 165 through the pressing plate 170 of the hot press is set to 70 ℃ ~ 100 ℃ Preferably, the reason is that if the heating temperature is set below 70 ° C, the pattern pattern due to the pattern pattern protrusion 165 of the transparent sheet 160 is properly formed on the upper protective sheet 110 of the card body part 100. This is because, if the temperature is set above 100 ° C., the transparent sheet 160 may be melted by heat.

In addition, the pressure for pressing the transparent sheet 160 formed with the card body portion 100 and the pattern pattern protrusion 165 is preferably 15 ~ 25kg / ㎠, the reason is that if the pressure is applied to less than 15cm 2 card body ( The pattern pattern due to the pattern pattern protrusion 165 of the transparent sheet 160 is not properly formed on the upper protective sheet 110 of 100, and when pressed at a pressure exceeding 25kg / ㎠, the compressive strength is so strong that the card body This is because cracks may occur in the part 100.

Next, the third step forms a bumpy fine pattern on the card body part 100 corresponding to the pattern pattern protrusion 165 of the transparent sheet 160 by the pressing of the second step.

Thereafter, in the fourth step, after the card body portion 100 and the transparent sheet 160 which are temporarily bonded are separated by cooling, a fine pattern pattern is formed on the upper protective sheet 110 as shown in FIG. 6. To complete.

In the following, a manufacturing process of the transparent sheet 160 on which the pattern protrusion 165 of the predetermined pattern is formed in the first step will be described with reference to FIGS. 7 and 8.

7 (a) and 7 (b) are views for explaining a transparent sheet manufacturing process applied to the present invention, Figure 8 is a photograph showing an example of the transparent sheet manufactured according to the present invention.

First, as shown in FIGS. 7A and 7B, in step 1-1, a fine intaglio or embossed pattern pattern 161 is formed on the plate 162 such as nickel or stainless by etching. .

At this time, the fine pattern pattern 161 is a photo paper for forming a predetermined pattern pattern 161 by laminating a draft paper having a fine pattern pattern formed on the plate 162, by applying a photosensitive etching solution to the pattern pattern and corrosion. Although preferably formed by etching, for example, as long as it is possible to form a fine pattern on the plate 162, not only etching but also plating and photolithography methods may be used.

Next, in the first and second steps, the UV liquid 163 having high strength and heat resistance at the time of subsequent curing, such as the sony SVR1320, is applied onto the plate 162 on which the intaglio pattern 161 is formed.

Next, in the 1-3 steps, the flat and transparent PET sheet 164 is laminated on the plate 162 to which the UV liquid 163 is applied, and pressed while passing through a pressure roller (not shown).

At the same time, in step 1-4, the UV liquid 163 on the compressed plate 162 is irradiated with ultraviolet rays through a UV lamp, and the UV liquid 163 is cured and attached onto the transparent PET sheet 164. To be.

Next, in step 1-5, the PET sheet 164 attached with the protrusion 165 formed by curing the UV solution 163 is cooled and separated, and then a predetermined bumpy pattern is provided at the bottom as shown in FIG. 8. The transparent sheet 160 having a pattern formed thereon is generated.

7A and 7B, although the predetermined pattern 161 on the plate 162 and the protrusion 165 formed under the transparent sheet 160 are sawtooth-shaped, As long as the card body part 100 can form a fine and uneven pattern on the upper protective sheet 110, it may be formed in a rectangular and semicircle shape.

Therefore, the card may not easily slide in the user's hand due to the uneven micro pattern of the card surface, and may provide aesthetic differentiation compared to other cards due to various pattern patterns.

In addition, since the transparent sheet 160 is precisely aligned on the surface of the card to be temporarily bonded to form a pattern, the card on the bottom of the card can be easily seen, thereby improving workability and productivity and significantly reducing the defective rate of pattern pattern formation. have.

On the other hand, the card manufactured by the above method is preferably 85.47 mm to 85.72 mm in length, 53.92 to 54.03 mm in width, and 0.68 mm to 0.84 mm in thickness so as to satisfy the international standard ISO7816.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.

That is, in one embodiment of the present invention, a magnetic stripe-attached card is described as an example, but it can be applied to an IC card, an R / F card, a Combi card, a similar card, and the like.
