DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

Referring to FIG. 1, a body film 201 is provided, which includes a first base film 100 made of a transparent synthetic resin film, And a second base film 120 made of a synthetic resin film.

The first base film (100) forms the opposite surface of the reflecting surface that forms a reflection when the sequins are produced, protects the sequins from external scratches and makes the sequins glossy and elastic, It is a base film that gives convenience.

The first base film 100 is selected from a transparent and glossy synthetic resin film. For example, the first base film 100 may be made of transparent polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE) One can be selected.

The first base film 100 preferably has a thickness of about 38 mu to about 150 mu, but is not limited thereto.

The first base film 100 is subjected to a surface treatment for enhancing adhesive strength and an adhesive is applied by using a coating apparatus to form an adhesive layer 110. The second base film 120 And the body film 201 is produced.

The second base film 120 has a cube-corner retroreflective layer formed on its upper surface, and a transparent synthetic resin film having good transparency of the ultraviolet curing lamp is used. For example, any one of materials such as polyvinyl chloride (PVC), thermoplastic polyurethane (TPU), and polyethylene (PE) may be selected and used.

The thickness of the second base film 120 is preferably about 20 占 퐉 to about 250 占 퐉, but is not limited thereto.

Such a second base film 120 may contain pigments or dyes to impart color, and thus the finished sequin film may have a color.

The adhesive constituting the adhesive layer 110 can be selected according to the type of the adhesive system and the first and second base films 100 and 120. For example, a dry lamination type polyurethane adhesive A photo-curable adhesive may be used.

2, a body film 201 is formed as described above, and a cube-corner retroreflective layer 130 is formed on the upper surface of the second base film 120 of the body film 201. [ .

In this case, an ultraviolet curable resin is applied to the upper surface of the second base film 120, and then the cube-corner retroreflective layer 130 is formed on the ultraviolet curable resin.

As such a method for forming the cube corner with respect to the ultraviolet ray hardening resin, any method known in the art can be used and can be produced by an individual method or a continuous method.

Conventionally, the method of forming the cube corner with respect to the ultraviolet ray hardening resin includes a process such as heating, pressing, ultraviolet ray irradiation, cooling and the like. In this case, pressurization refers to pressing the cube corner shape of the engraved angle to the ultraviolet ray hardening resin so as to form a cube corner shape of an embossed shape in order to form the ultraviolet ray hardening resin with the cube corner retroreflective layer 130. For example, An embossing belt disclosed in Japanese Patent No. 0614309 may be used.

The cube-corner retroreflective layer 130 may be formed on the ultraviolet curable resin by the method disclosed in Korean Patent Registration No. 0891901 with reference to FIG.

The ultraviolet ray hardening resin should take into account the mechanical strength, thermal stability, weatherability, surface tension, etc., and match the wavelength of the ultraviolet ray hardening lamp with that of the ultraviolet ray hardening resin. Also, You must meet as much as you need.

The composition of the ultraviolet ray hardening resin is composed of an oligomer, a reactive monomer, a photoinitiator, and other additives. Examples of the photopolymerizable oligomer include polyester acrylate, epoxy acrylate, and urethane acrylate. It is widely used for improving the adhesiveness in plastic or metal. It is easy to handle and has good pigment spraying property. Epoxy acrylate is excellent in hardness flexibility hardening property because it has the property of epoxy resin. And is a resin having relatively stable characteristics.

As described above, the cube corner type retroreflective layer 130 is formed on the top surface of the body film 201, and the sequin film 301 according to the present invention is primarily completed.

The sequins can be completed by processing the sequins film 301 into various forms such as a circle, a star, a heart, and the like. Such a sequin is a thin film which has a retroreflective reflection and has a characteristic of excellent visibility due to its retroreflective property and particularly excellent night vision.

The sequins made by processing the sequin film 301 formed by forming the cube corner type retroreflective layer 130 on the upper surface of the body film 201 and processing the retroreflective layer 130 are particularly suitable for embracing.

According to the present invention, it is preferable to form a cube-corner retroreflective layer 130 on the top surface of the body film 201, and then subject the prism surface to metal deposition to form the specular reflection layer 140. This state is shown in FIG.

The specular surface reflection layer 140 is formed of a metal such as aluminum, copper, silver, or nickel by a method such as vacuum deposition, chemical plating, or sputtering. For example, aluminum is deposited using a vacuum deposition method using a continuous deposition method , And the thickness thereof may be 800 ANGSTROM to 2000 ANGSTROM.

The sequins produced by processing the sequin film 401 formed by forming the cube-corner retroreflective layer 130 on the upper surface of the body film 201 and forming the specular surface reflection layer 140 on the upper surface thereof, The retroreflective function can be exhibited irrespective of whether it is suitable for outdoor clothing or a tent or backpack.

Next, according to the present invention, a hot melt adhesive layer 150 and a release paper 160 are laminated on the upper surface of the specular reflection layer 140 to complete the sequin film 501, and the finished sequin film 501 is processed The sequins can be thermally adhered to clothes, fabrics and the like. This state is shown in FIG.

It is preferable to perform surface modification such as formation of irregularities on the surface of the deposition surface since the surface of the metal deposition-molded surface is usually weak. Also, after the anchor coating is performed, the hot-melt adhesive 150 is applied to the specular reflection layer 140 It is preferable to prevent the catalyst from being desorbed.

The hot-melt adhesive 150 has various types such as polyurethane, polyamide, polyester, and eva, and may be selected depending on the kind of the adhesive.

The hot melt adhesive layer 150 and the releasing paper 160 may be formed by attaching a release paper coated with a hot melt adhesive to the specular reflection layer 140.

In this case, the cube-corner retroreflective layer 130 is formed on the upper surface of the body film 201, the specular reflection layer 140 is formed on the upper surface of the reflective film 140, and the hot melt adhesive layer 150 and the release paper 160 are laminated on the upper surface thereof. The use film 501 is processed into various shapes such as a circle, a star shape, a heart shape, and the like, and is completed with sequins and can be attached to clothes, fabrics, bags or the like by thermal bonding.

The film for sequins provided according to the present invention is a thin film which is made to reflexively reflect and glow, and its visibility is ensured due to its retroreflective property.

The sequin film provided according to the present invention is processed into a specific shape to complete a sequin. Such a sequin is also a thin film, which is reflexively reflected to form a sparkle, and visibility is ensured due to its retroreflective property.

It will be understood that the objects of the present invention are achieved thereby. Although the present invention has been described with reference to the embodiments thereof, it should be understood that the scope of the present invention is not limited thereto.
