<First Embodiment>

1 and 3, the manufacturing method of Jeonju Deco product using the UV pattern growth according to the first embodiment of the present invention, as shown in Figure 1 (a), a negative portion for forming an image or pattern The mold 10 in which the 11 was formed is provided (S1). The engraved portion 11 is represented in the form of a square in FIG. 1 (a) for convenience, but may be formed in various shapes for representing an image.

The image or pattern formed on the intaglio portion 11 of the mold 10 is processed using a variety of methods such as laser, hairline or etching, CNC, etc., as well as the general mold as well as the electroforming master mold capable of forming a precise pattern It may be provided.

Here, the image may include, for example, a trademark label or a logo of an electrical and electronic product, and the pattern may include various patterns of patterns including elaborate patterns such as holograms and spins. The intaglio portion 11 may include a finely embossed image or pattern of a very fine degree, which is a double expression and more by expressing the intaglio and embossed images or patterns together in the Jeonju Deco product to be manufactured To give an excellent three-dimensional effect.

As shown in Figure 1 (b) in the intaglio portion 11 of the mold 10, the UV paint (P) having a UV (Ultra Violet) reaction is injected and applied to the entire surface of the mold 10 (S2) ).

Subsequently, as shown in FIG. 1 (c), the UV paint P is injected into the intaglio portion 11 of the mold 10 and applied to the upper surface of the mold 10 in the state of being applied to the entire mold. The transparent synthetic resin film 101 is placed on the seat (S3).

At this time, the synthetic resin film 101 is in close contact with the UV paint (P) side injected into the intaglio portion 11 is in contact with each other.

In the state in which the synthetic resin film 101 is seated on the upper surface of the mold 10, as shown in FIG. 1 (d), it is flat and pressed using the pressing roller 20 (S4).

At this time, the pressing operation through the pressing roller 20 can be evenly pressed over the entire surface, the image or pattern formed on the intaglio portion 11 of the mold 10 on the UV paint (P) side is transferred ( Iii) and the synthetic resin film 101 and the UV paint (P) is bonded to form a bonding relationship.

The UV coating (P) and the synthetic resin film 101 to be in the mutual adhesive bonding state through the pressing operation to cure the UV coating (P) through the reaction with the ultraviolet (S5). At this time, the ultraviolet rays are transmitted through the transparent synthetic resin film 101 to reach the UV paint (P) is to enable the ultraviolet photosensitive reaction.

Subsequently, the synthetic resin film 101 is detached from the mold 10 and separated (S6).

At this time, when the synthetic resin film 101 is separated from the mold 10, as shown in FIG. 1 (f), the pattern forming film F having the UV coating layer 102 formed on the upper surface of the synthetic resin film 101 is formed. ), And the UV paint layer 102 has an embossed pattern corresponding to the image or pattern formed on the intaglio portion 11 of the mold 10.

At this time, it can be confirmed by the present inventors that the external light can thinly penetrate the metal deposition layer 103 so that the external visibility of the image pattern can be ultimately improved by a dark color such as black of the dark lower printing layer PR. The finer the thickness of the metal deposition layer 103 was, the more effective the visibility of the pattern image was. However, when the trivalent chromium plating layer described above is plated, since the thickness of the metal layer may be increased, the lower printed layer PR may not be necessary.

When the resultant thin plate is punched out as described above, it is possible to manufacture the Jeonju Deco product 100 that can express the impression of the pole and the metal as shown in Figure 5 (S8).
