The present invention relates to a decorative adhesive tape, and more particularly, to a decorative adhesive tape to have a tackiness and at the same time a decorative effect by applying an adhesive on a plastic film that is different in color depending on the viewing angle.

In general, since the adhesive tape has a structure in which the pressure-sensitive adhesive layer 2 on which the pressure-sensitive adhesive is applied onto the resin film layer 1 and the release layer 3 are laminated thereon, as shown in FIG. When used in industrial, office, etc., it was used only in a simple form, and the decorative effect could not be expected.

Therefore, the present invention is a new decorative material with a beautiful color that can be widely applied for decoration by applying a plastic film in which the metal deposition layer and the transparent resin layer are laminated on the adhesive tape so that the color looks different depending on the viewing angle due to the inter-layer refractive index difference. The purpose is to provide an adhesive tape.

Hereinafter, described in detail with the accompanying drawings of the present invention as follows.

In the decorative adhesive tape comprising the base film, the pressure-sensitive adhesive layer, and the release layer of the present invention, the pressure-sensitive adhesive layer (2) and the release layer (3) are formed on the plastic film layer (4) which is different in color depending on the angle as the base film. The plastic film layer 4 is formed side by side, but the metal film layer 7 and the transparent resin layer 8 are repeated one to four times under the resin film layer 1, the release layer 5, and the protective layer 6. It is characterized by having a multi-layered structure which is formed and continues with a primer (Primer) layer 9 and a total reflection film 10 of the metal deposition layer.

As described above in more detail the adhesive tape of the present invention.

The decorative adhesive tape of the present invention has a plastic film layer 4 that varies in color depending on the viewing angle as a base film as shown in FIG. 2, and the adhesive layer 2 and the release layer 3 are sequentially formed thereon. It has a basic structure.

Here, the plastic film layer 4 is a base film exhibiting a beautiful color change, and essentially the metal deposition layer 7 and the transparent resin layer 8 are repeated 1 to 4 times, preferably 2 to 3 times. Various colors are generated from the metal deposition layer according to the stacked angle, and the structure of the plastic film layer 4 is shown in FIGS. 3, 4, 5, 6, 7 and Many variations are also possible, as illustrated by the embodiment in FIG.

Looking at the configuration of such a plastic film layer 4 in more detail, the resin layer 1 and the protective layer 6 is formed, as in the case of FIGS. 3 and 4, the metal deposition layer 7 thereunder And the transparent resin layer 8 are repeatedly formed twice (FIG. 3) or three times (FIG. 4), and the total reflection film 10 of the primer layer 9 and the metal deposition layer is formed thereunder. Or; As shown in FIGS. 5 and 6, a release layer 5 is formed between the resin layer 1 and the protective layer 6 in FIGS. 3 and 4, and the metal deposition layer The adhesive layer 11 and the resin layer 11 are formed next to the total reflection film 10 of; As shown in Figs. 7 and 10, those having a structure in which the adhesive layer 11 and the resin layer 1 are again formed on the resin layers 1 of Figs. 3 and 4 can be used.

The resin layer 1 forming the structure of the plastic film layer 4 having such a structure is used to enhance the strength of the film, and one resin film selected from polypropylene, polyethylene terephthalate, polyvinyl chloride, and polyamide film is used. Can be.

As the protective layer 6, resins such as melamine, epoxy, vaginal screen, acryl, phenol, isocyanate or urethane are used. As the metal deposition layer 7, the visible light transmittance is 5 to 80%. As the transparent resin layer 8, a vinyl, acrylic or phenolic transparent resin can be used. A primer layer 9 is formed after the metal deposition layer 7 and the transparent resin layer 8, and the total reflection film 10 of the metal deposition layer having a thickness of 300 to 800 Å is formed on the bottom of the metal deposition layer 7 and the transparent resin layer 8. And metals such as zinc and the like are deposited at an optical density of 1.8 to 4.0.

At this time, the primer layer 9 is to protect the metal deposition layer 7 from chemical penetration, 1 to 18% by weight of vinyl acetate and vinyl chloride copolymer resin, 2 to 23% by weight of acrylic resin isopropanol or the like It is formed by dissolving in a mixed solvent.

According to the present invention, a general adhesive layer 11 may be formed after the total reflection film 10, and the adhesive layer 11 and the resin film layer 1 may be formed on the resin film layer 1 again. .

As such, the plastic film layer 4 in the decorative adhesive tape according to the present invention is preferably a total thickness of about 7.0㎛ ~ 150㎛ bar, if the thickness is thinner than 7.0㎛, the strength is too weak, 150㎛ Larger sizes are not only uneconomical, but the tape's thickness is so thick that its value of use is limited, which is undesirable.

On the other hand, the present invention as described above, the adhesive tape on the plastic film layer 4 as a separate film for polyethylene terephthalate, polycarbonate, polymethyl methacrylate, polypropylene, polystyrene, polyvinyl chloride or ethylene vinyl acetate The film may be used in a laminated state.

As described above, the decorative adhesive tape according to the present invention after forming an adhesive layer such as rubber and acrylic resin on the plastic film of the multi-layer structure as described above, re-laminating the release paper and required printing and die cutting (Die Cutting) It is then wound up to obtain a decorative adhesive tape. In this case, in order to manufacture the adhesive tape of the present invention, a resin film having a thickness of 7.0 to 40 microns is advantageous in manufacturing, but particularly for the use of decorative labels and stickers, those having a thickness of 40 to 150 microns may be effectively used. In addition, for the production of a decorative adhesive tape according to the present invention may be prepared by manufacturing a plastic film layer having the above structure and using a single film of the required thickness or by laminating other films according to convenience.

When explaining an example of manufacturing the decorative adhesive tape of the present invention in detail, the plastic film (SKC PET Film: SM-30) having a light thickness of 25 microns is made in the structure of FIG. A 50 micron thick polyethylene terephthalate film was laminated onto a urethane adhesive (A-850B from BF Goodrich, USA). At this time, as the laminating conditions, the gravure (Gravure) was also used to give up the adhesive to a thickness of 3 microns, and then dried at 100 ℃ for 30 seconds. The acrylic adhesive is coated on the laminated film by a known method using a Comma Knife applicator to a thickness of 25 microns, dried at 100 ° C., then re-laminated on a release paper, die cut, and then wound to obtain a beautiful decorative color. The label was prepared. The prepared decorative tape can be used for various purposes by removing the release paper during use and adhesively using the adhesive layer.

The decorative adhesive tape of the present invention manufactured as described above is not only beautiful in color but also has adhesiveness, and thus is very useful for packaging, office and decoration in each field.
