1 schematically shows a cross-section of an advertisement film 100 according to an embodiment of the present invention.

Referring to FIG. 1 , the advertising film 100 is a surface protective layer 10 , a base layer 20 , a first adhesive layer 30-1, a metal film 40 and a second adhesive layer 30- from above. 2) sequentially, and the metal film 40 includes a resin layer 41 and at least one metal deposition layer 42 disposed on one surface of the resin layer. 1 illustrates an example in which the metal deposition layer 42 is formed of a single layer.

In the advertising film 100, the surface protective layer 10 corresponds to the outermost layer, and when the advertising film 100 is attached to an adherend such as a signboard, building, vehicle, glass, lighting, etc., the It is the layer furthest from the complex. The surface protective layer 10 serves to secure weather resistance and scratch resistance by protecting other layers disposed on one surface thereof.

In addition, the base layer 20 is a layer serving as one of the basic functions of the advertising film 100 for imparting color, and in one embodiment, may be a layer having a color while having a predetermined light transmittance. If necessary, the base layer 20 may be formed of a colorless and transparent layer.

In addition, the base layer 20 is attached via the metal film 40 and the first adhesive layer 30-1, and more specifically, the resin layer 41 of the metal film 40 and the The first adhesive layer 30 - 1 may be attached as a medium. That is, the base layer 20 is attached to the resin layer 41 through the first adhesive layer 30-1, thereby effectively preventing corrosion and oxidation of the metal deposition layer 42 thereunder. and can greatly contribute to protecting the appearance of the advertising film 100 and improving durability.

In the advertising film 100, the base layer 20 contains polyvinyl chloride (PVC) as a main component, and at the same time, the surface protective layer 10 contains a non-polyvinyl chloride (PVC) resin as a main component. include as

When the base layer 20 includes polyvinyl chloride (PVC) as a main component, it is possible to secure the advantage of easier color application compared to the case made of other materials such as polyethylene terephthalate (PET). In addition, when the base layer 20 containing polyvinyl chloride (PVC) as a main component and the surface protection layer 10 containing a non-polyvinyl chloride (PVC) resin as a main component are used together, both layers are polychlorinated When vinyl (PVC) is included as a main component; Alternatively, the discoloration prevention performance may be significantly improved compared to each case in which both layers include non-polyvinyl chloride (PVC) as a main component.

Referring to FIG. 1 , the metal film 40 may have a multilayer structure including the resin layer 41 and at least one metal deposition layer 42 disposed on one surface of the resin layer 41 . there is. The metal deposition layer 42 may have a single-layer structure or a multi-layer structure, and in the case of a multi-layer structure, each layer may have the same or different components.

The metal film 40 serves to impart a metal texture and excellent weather resistance to the advertising film 100 . Although the metal texture can be implemented only with the metal deposition layer 42, when the metal film 40 is made of only the metal deposition layer 42 without the resin layer 41, weather resistance and durability can be achieved at a desired level. There is a difficult problem. That is, since the metal film 40 includes the metal deposition layer 42 disposed on one surface of the resin layer 41 , excellent metal texture, excellent durability, and weather resistance can be secured at the same time.

More specifically, as shown in FIG. 1 , in the multilayer structure of the advertising film 100 , the metal film 40 has the resin layer 41 disposed on the first adhesive layer 30-1 side. and the metal deposition layer 42 may be included to be disposed on the side of the second adhesive layer 30 - 2 .

More specifically, the metal nitride is silicon-nitride (Si-Nx), silicon aluminum-nitride (SiAl-Nx), titanium zirconium-nitride (TiZr-Nx), silicon zirconium-nitride (SiZr-Nx), and combinations thereof may include one selected from the group consisting of, the metal oxide is zinc-oxide (Zn-Ox), zinc aluminum-oxide (ZnAl-Ox), titanium dioxide (TiO ₂ ), zinc tin-oxide (ZnSn-Ox) ) and may include one selected from the group consisting of combinations thereof.

In one embodiment, the advertising film 200 may have a structure in which the metal deposition layer 42 of the metal film 40 includes aluminum (Al) and the ceramic layer 43 on both sides thereof. there is. Accordingly, the metal film 40 may simultaneously secure improved weather resistance and durability due to the ceramic layer 43 as well as the excellent metal effect of aluminum (Al).

The surface protection layer 10 may have a thickness of about 1 μm to about 30 μm, for example, about 3 μm to about 15 μm.

The polyvinyl chloride (PVC) base layer 20 may be a cast film made by thinly spreading and drying a liquid composition containing polyvinyl chloride (PVC) resin as a main component to a predetermined thickness and width.

Conventionally, a calendar film has been mainly used as a sheet or film using polyvinyl chloride (PVC). A calendar film refers to a film made by thinly spreading a polyvinyl chloride (PVC) composition in a kneaded state through a high-temperature extrusion process. However, since such a calendar film has poor dimensional stability and durability, it is suitable for short-term use, but is not suitable for long-term use. Therefore, the advertising films 100 and 200 according to an embodiment of the present invention by using a cast film as the polyvinyl chloride (PVC) base layer 20, the manufacturing process of the base layer 20 In the process stress (stress) can be minimized, and through this, the dimensional stability and durability of the base layer 20 can be improved, and as a result, the dimensional stability and long-term durability of the advertising films 100 and 200 are improved. advantage can be obtained.

Specifically, the polyvinyl chloride (PVC) base layer may be prepared from a liquid composition including a polyvinyl chloride (PVC) resin and a polymer plasticizer. In this case, the K-value of the polyvinyl chloride (PVC) resin may be about 50 to about 95, for example, about 65 to about 85. In the present specification, 'K-value' is an empirical parameter closely related to the intrinsic viscosity of the polyvinyl chloride (PVC) resin. It is defined as a Fikentscher K-value (see DIN EN ISO 1628-1).

In addition, the polymer plasticizer may have a weight average molecular weight (Mw) of about 1,000 to about 20,000, for example, about 3,000 to about 6,000.

By using a polyvinyl chloride (PVC) resin that satisfies these conditions and a polymer plasticizer, the polyvinyl chloride (PVC) base layer can be formed with a uniform thickness, and durability and moldability can be excellently implemented. Specifically, the polymer plasticizer is succinic acid, adipic acid, glutaric acid, pimelic acid, azelaic acid, sebacic acid, and It may include a diester polymer compound derived from any one dicarboxylic acid selected from the group consisting of combinations thereof.

If necessary, the polymer plasticizer may further include a benzoate-based plasticizer, an epoxidized oil plasticizer, etc. that satisfy the above-described weight average molecular weight (Mw) range, but is not limited thereto. .

The polyvinyl chloride (PVC) base layer 20 may include about 10 to about 50 parts by weight of the polymer plasticizer based on 100 parts by weight of the polyvinyl chloride resin, for example, about 25 to about 40 parts by weight. may include parts. When the content ratio of the polyvinyl chloride resin and the polymer plasticizer satisfies the above range, it is possible to obtain an advantage in terms of securing 2D construction properties while preventing migration of the plasticizer.

As described above, the polyvinyl chloride (PVC) base layer 20 may be a layer having a color while having a predetermined light transmittance. For example, the light transmittance of the polyvinyl chloride (PVC) base layer 20 may be about 50% to about 100%, for example, about 50% to about 80%.

The base layer 20 may be manufactured to have a necessary color by further adding ink, pigment, dye, etc. to a liquid raw material composition containing polyvinyl chloride (PVC) as a main component during the manufacturing process.

The base layer 20 may have a thickness of about 30 μm to about 120 μm, for example, about 40 μm to about 80 μm.

1 and 2 , the advertising films 100 and 200 include a first adhesive layer 30-1 and a second adhesive layer 30-2. Specifically, the first adhesive layer 30-1 serves to attach the polyvinyl chloride base layer 20 and the metal film 40, and the second adhesive layer 30-2 is the advertising film ( 100, 200) and the adherend to which it is finally applied.

The first adhesive layer 30-1 and the second adhesive layer 30-2 each include one selected from the group consisting of an acrylic adhesive, an ester-based adhesive, a silicone-based adhesive, an epoxy-based adhesive, a urethane-based adhesive, and combinations thereof. can

The first adhesive layer 30-1 and the second adhesive layer 30-2 may be formed of the same adhesive or different adhesives. In one embodiment, the first adhesive layer 30-1 and the second adhesive layer 30-2 may each include an acrylic adhesive, and in this case, room temperature lamination is possible, so the process compared to other types of adhesives can get an advantage.

Each of the first adhesive layer 30-1 and the second adhesive layer 30-2 may have a thickness of about 10 μm to about 80 μm, for example, about 30 μm to about 45 μm.

The metal deposition layer 42 of the metal film 40 may have a thickness of about 10 nm to about 200 nm, for example, about 30 nm to about 130 nm. Since the metal deposition layer 42 satisfies this thickness range, it is possible to excellently implement a metal effect due to metallic luster during the daytime, and at the same time, at the same time, it is possible to excellently implement a unique appearance when light is transmitted at night.

The metal deposition layer 42 is manufactured by depositing a metal component through a deposition process. In this case, the metal deposition layer 42 may include a sputtering deposition film or a thermal-vacuum evaporation film.

A deposition method for forming the metal thin film includes thermal vacuum evaporation, sputtering deposition, and ion-beam assisted deposition.

Among them, the ion beam assisted deposition method has a disadvantage in that the process cost is too high compared to the effect of realizing the desired physical properties.

The thermal-vacuum evaporation deposition method is a method of vaporizing a metal raw material by applying high heat in a vacuum state, and then solidifying it on a substrate at a relatively low temperature. This is a method in which the metal atoms collide with a collision energy greater than the binding energy between the metal atoms in the raw material, and the metal atoms are ejected and deposited on the target substrate.

When the metal deposition layer 42 is made of a sputtering deposition film or a thermal-vacuum evaporation deposition film, it is possible to secure a high deposition density and excellent deposition uniformity compared to films by other deposition methods, and as a result, the desired metal Implementation of the effect may be possible. In one embodiment, the metal deposition layer 42 may be a sputtering deposition film, and in this case, there is a more advantageous advantage in terms of uniformly implemented large-area deposition.

In the metal film 40 , the resin layer 41 may have a thickness of about 20 μm to about 150 μm, for example, about 35 μm to about 100 μm.

The resin layer 41 may include one selected from the group consisting of an acrylic film, a polyethylene terephthalate (PET) film, and combinations thereof. The resin layer 41 becomes a target substrate for deposition when the metal deposition layer 42 is manufactured, and in the advertising films 100 and 200 , a passivation layer for preventing corrosion and oxidation of the metal deposition layer 42 . It can function as a passivation layer, and by being made of the above-described material, this function can be excellently implemented.

The advertising films 100 and 200 may be used for indoor or outdoor advertising by attaching them to a signboard, building, vehicle, glass, lighting, etc., and in particular, may be applied to the front of an outdoor signboard equipped with a rear light.

Referring to FIG. 4 , the advertising film 100 is applied to the outdoor signage 60 with lighting, and in the daytime when the lighting is not turned on, an excellent appearance is realized through the metal effect by the metallic luster, and the lighting is turned on. can implement an improved appearance effect according to the light passing through the advertising film 100 at night.

In one embodiment, the advertising films 100 and 200 may have a total thickness of about 100 μm to about 250 μm, and a light transmittance in this thickness range of about 20% to about 80%, for example, from about 30% to about 60%. The thickness and light transmittance of the advertising films 100 and 200 are measured values for a structure excluding the release layer 50 as will be described later. Since the advertising films 100 and 200 satisfy the light transmittance in the above range at such a thickness, both the daytime and nighttime appearance effects as described above can be excellently implemented.

In addition, the advertising films 100 and 200, as described above, through the overall structure in which each layer is sequentially laminated, is not affected by various climate changes and external environments, and excellent weather resistance and durability can be implemented for a long period of time. .

Referring to FIG. 5 , the advertising film 100 may include a cavity formed to engrave a predetermined design, text, picture, etc., before being applied to the outdoor signboard 60 with lighting. That is, in order to engrave a design, text, picture, etc. according to the purpose of the advertisement, the advertisement film 100 may be partially cut out to form a cavity (A). In this case, at night when the light is turned on, the light emitted from the light is transmitted through the cut-out portion without filtration to realize an advertisement effect.

Although not shown in the drawings, a separate protective film may be disposed on the uppermost part after the advertisement film 100 is partially cut out to form the cavity (A). The protective film may be an adhesive film in which an adhesive layer is formed on one surface of a polyethylene terephthalate (PET) substrate or a polyvinyl chloride (PVC) substrate.

The advertisement film 100 has an overall structure in which each of the above-described layers is sequentially laminated, so that the entire laminated structure can have properties that can be neatly cut, and the cavity (A) of a complex shape is also excellent without defects based on excellent processability. can be formed.

These physical properties may be implemented in the same way for the advertisement film 200 of FIG. 2 not shown in the drawings.

Referring to FIG. 3 , the advertising film 300 may further include a release layer 50 under the second adhesive layer 30 - 2 in the advertising film 100 having the structure of FIG. 1 . there is. The release layer 50 serves to secure the distribution and storability of the advertising film 300 , and may be used without limitation as long as it is a film used as a normal release film.

In one embodiment, the release layer 50 may be a film including a polyethylene (PE) material and a silicone release agent applied to one surface thereof. The release layer 50 can be removed before the advertisement film is applied to the adherend, and by using the release layer 50 of the above material, there is no transfer of the adhesive in relation to the second adhesive layer 30-2. It can be peeled off cleanly.

The release layer 50 may be formed in the same manner for the advertisement film 200 of FIG. 2 not shown in the drawings.
