Abstract

PURPOSE:To easily obtain a lure having a tough and peel-resistant coating layer exhibiting excellent metallic luster and varied colors and patterns by transferring a metallized film to the main body of a lure by the aid of an ultraviolet-curable coating material using a specific method. CONSTITUTION:An ultraviolet-curable coating material is applied to the surface of the main body 1 of a lure to form a coating film 4. The coating film 4 is irradiated with ultraviolet ray to cure the film to a proper hardness. A transfer sheet 10 having a metallized film on a synthetic resin film is hot-pressed to the coating film 4 to transfer the metallized film to the coating film 4. Finally, the transferred layer is protected by coating with a synthetic resin protecting film. The hot-pressing is preferably carried out by using a male die 20 and a female die 21 made of silicone rubber, etc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lure manufacturing method.

[0002]

2. Description of the Related Art There are various shapes of lures,
In particular, we are trying to induce fish by making ingenuity in the surface color and pattern.

It is known that it is more effective to impart metallic luster to the color and pattern of the lure surface.

[0004]

Means for imparting a metallic luster include metal plating, metal vapor deposition, and metal foil bonding.

However, plating and vapor deposition have the problems that it is difficult to form a uniform and glossy coating, it takes time to change the color, and the adhesion to the lure body is not sufficient and peeling is easy. .

Further, when a metal foil is attached, there is a problem that the lure body is difficult to fit into the curved surface of the lure body and wrinkles are generated, so that the luster is reduced. Therefore, divide the metal foil into small pieces,
The method of sticking these one by one is adopted, but needless to say, this is very inefficient in working, and there is a problem that the finished product lacks uniform gloss.

Therefore, an object of the present invention is to provide a method for producing a lure which is strong and does not peel off, has an excellent metallic luster, and can easily obtain a variety of colors and patterns.

[0008]

In order to solve the above problems, in the present invention, an ultraviolet curable coating material is applied to the surface of the lure body, and the coating film is irradiated with ultraviolet rays to be cured to an appropriate hardness, A transfer sheet having a metal vapor deposition film formed on a synthetic resin film was thermocompression bonded to transfer the metal vapor deposition film to form a synthetic resin protective film.

[0009]

[Function] After the UV-curable coating applied to the surface of the lure body is cured to an appropriate hardness, the metal vapor deposition film is transferred by heating and pressure bonding so that the thin metal vapor deposition film fits well on the curved surface of the lure body. It adheres firmly and gives a surface with an excellent metallic luster.

[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 and 2 show an example of a lure body. As shown in the figure, the lure body 1 has a plane elliptical shape with a bulged central portion as a whole, and fishing line and fishing hook locking holes 2 and 3 are provided at both ends. The material of the lure body 1 is iron, brass, synthetic resin or the like.

An ultraviolet curable coating material is applied to the surface of the lure body 1 to form a coating film 4. This UV-curable coating is composed of three main components, for example, a prepolymer having a polymerizable functional group such as a polyfunctional ester acrylate, a reactive diluent (monomer), and a photosynthesis initiator. Additives such as accelerators, stabilizers, leveling agents, defoamers, and colorants are added.

The coating method may be dipping, curved pad printing, or the like.

After the coating film 4 is formed, the coating film 4 is passed through a curing device provided with a light source for generating ultraviolet rays, such as a mercury lamp, and the coating film 4 is exposed to ultraviolet rays for, for example, several seconds to 20 seconds to obtain an appropriate hardness. To cure.

On the coating film 4 thus irradiated with ultraviolet rays, thermocompression bonding (hot stamping) is performed using a transfer sheet having a large flexibility.

FIG. 3 shows an example of the transfer sheet. As shown in the figure, the transfer sheet 10 is formed by forming a metal vapor deposition film 12 of aluminum or the like on a support film 11 of polyester or the like, and providing a synthetic resin protective layer 13 on the outer surface thereof. A colorant may be mixed into the protective layer 13 or a process of exposing a hologram pattern may be performed.

Further, the surface of the support film 11 is subjected to treatment such as corona discharge so that the metal vapor deposition film 12 can be smoothly peeled off in a later step.

The thermocompression bonding is performed using a pressing die as shown in FIG.

As shown in the figure, the male die 20 has a recess 20a having a complementary shape with the surface of the lure body 1 on which the coating film 4 is formed, and the female die 21 has a complementary shape with the lower surface of the lure body 1. Are provided so that the male die 20 and the female die 21 can approach or separate from each other. These male 20 and female 2
It is desirable that 1 is made of a heat-resistant elastic material such as silicone rubber.

The luer body 1 is set in the female die 21 as shown in FIG. 4, and the transfer sheet 10 is inserted between the male die 20 and the female die 21 so that the protective layer 13 is on the luer body 1 side. .

Then, as shown in FIG.
When the transfer sheet 10 is pressure-bonded to the luer body 1 at a temperature of up to 250 ° C., the protective layer 13 is bonded to the surface of the coating film 4. Then, when the molds 20 and 21 are separated from each other, the metal vapor deposition film 12 is separated from the support film 11 of the transfer sheet 10 and transferred onto the surface of the lure body 1 as shown in FIG. At this time, since the transfer sheet 1 has flexibility, the transfer sheet 1 fits well to the curved surface of the lure body 1 and is smoothly transferred without wrinkles on the metal vapor deposition film 12.

As shown in FIG. 7, the obtained lure body 1
If necessary, a colored layer 14 is formed on the outer surface of the metal vapor deposition film 12a.
And a protective film 15 having good weather resistance such as epoxy resin or Teflon resin is formed.

[0023]

[Effects] According to the present invention, as described above, the method of transferring the metal vapor deposition film to the lure body via the ultraviolet curable coating is adopted, so that the metal vapor deposition film is formed firmly and without wrinkles on the surface of the lure body. It has excellent metallic luster, and various colors and patterns can be formed on the transfer sheet in advance by printing, etc., eliminating the need to form colors and patterns on each finished lure body. It is possible to obtain a variety of lures very efficiently.
