Description

[Detailed description of the invention] This invention relates to a metallized foil, and more specifically, it uses two base materials, and two metallization layers are deposited between the two base materials via an adhesive layer. This invention relates to a metal-deposited foil having a two-layer structure.

Conventionally, metal vapor-deposited foils are produced by forming an undercoat layer on a base film, and providing a metal vapor-deposited layer thereon. In addition, there are also those in which a top coat layer is further formed on the metal vapor deposited layer.

However, these metal-deposited foils had lower utility value than so-called hand-made foils such as gold leaf and silver leaf made by handicrafts.

That is, hand foil is heavy, flexible, and has good adhesion, whereas the metallized foil is light and has poor flexibility and adhesion. For example, when pasting such metallized foil on an object, Unlike hand foil, this metal-deposited foil is susceptible to air resistance on the bonding surface of the metal-deposited foil, and it is difficult to expel the air existing between the bonding surface and the surface of the object to be pasted. It is difficult to stick the metallized foil tightly and closely to the surface of the object to be pasted, and on the contrary, air gets trapped between the surface of the metallized foil and the surface of the object to which the metallized foil is pasted. There are often irregularities caused by air bubbles, etc., and the metal-deposited foil sometimes peels off from such irregularities. Therefore, when gold foil is used over a wide range of bonding surfaces, such as gold foil used on the inner walls of Buddhist altars, it is difficult to use such metallized foils. Furthermore, due to the above-mentioned points, it is difficult to freely cut the metal-deposited foil into a fixed shape, and therefore it is not used for cut foil, Noge, Sunago, etc., which are cut into appropriate dimensions. Ta.

In addition, the conventional metallized foil described above has less flexibility than stamped foil, and is thin and hard, so after laminating the metallized foil, cracks often occur, and the metallized foil sometimes peels off. .

In addition to the above-described one-layer metal-deposited foil, conventional metal-deposited foils include those with two metal-deposited layers, for example, a gold vapor-deposited layer is formed on a base film, and the metal-deposited layer is formed on the base film. There is also a structure in which a top coat layer (thin resin layer) is provided on top of the metal layer, and a gold vapor-deposited layer is further formed thereon to form a two-layer metal vapor-deposited layer. However, this two-layer structure simply forms two metal vapor deposited layers with a thin resin layer sandwiched between them, and the two metal vapor deposited layers are organically linked to form a single metal vapor deposited layer. Therefore, the above-mentioned metal vapor-deposited layer has the same drawbacks as a single layer of metal-deposited foil, and its uses are limited.

Therefore, in view of the drawbacks of the conventional metal-deposited foils, the present invention forms the metal-deposited layer as a two-layer structure using an adhesive, and also connects the two metal-deposited layers between two opposing base materials. By forming the foil into a metallized metal foil, the present invention aims to provide a metallized metallized foil with properties equivalent to those of conventional stamped foil, and to provide a metallized metallized foil that eliminates the above-mentioned drawbacks and has high utility value.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a schematic longitudinal cross-sectional view of the metal-deposited foil of the present invention, and 1 and 1 are two base materials facing each other. This base material is a plastic film or release paper. The plastic film is not particularly limited, but films such as polypropylene, polyethylene, polyester, Tetron, and nylon are used. In the figure, plastic film is used, but these two base films may be formed from the same film, or may be formed from different types of films in relation to peeling.For example, one may be formed from a plastic film. When a Tetron film is used and the other is a polypropylene film, the other polypropylene film can be peeled off without the need to provide the release layer described below, and the base film is of a different type, making it easy to peel off. The degree can be adjusted.

2 and 2 are release layers, and the base films 1 and 1 are
Apply a mold release agent on top. For example, acrylic or cellulose resin is used as the mold release agent, but the release agent is not limited to these. Moreover, the release layers 2, 2 are the base films 1, 2,
As mentioned in Section 1, this is not necessary in the case of a film with good mold releasability, and is provided as necessary.
When forming the release layers 2, 2 on the base films 1, 1, respectively, as in the embodiment shown in FIG. It is also possible to provide release layers 2, 2 which are different from those shown in FIG. In such a case, one base film 1 can be easily peeled off before use, and the other base film 1 can be peeled off immediately before use, facilitating the use of the metallized foil. It is something that can be done.

Further, 3, 3 is a coating resin layer, and when the above mold release layers 2, 2 are provided on the base films 1, 1, the mold release layers 2, 2 are not formed on the mold release layers 2, 2. In this case, a resin coating is applied directly onto the base films 1, 1 to form a coating resin layer. In addition, the coating resin layers 3, 3 are
For example, in the case of vapor-deposited metals, such as pure gold and pure silver, there are cases where it is possible to make the film look more like stamped foil by not providing a so-called top coat. Therefore, it is not always necessary to form two coating resin layers, and depending on the metal to be deposited or other reasons, only one coating resin layer may be used.

As the coating resin paint, for example, a melamine resin or an acrylic resin is used, but other resins may be used without particular limitation. In addition to forming the coating resin layers 3, 3 as transparent resin layers, depending on the type of metal to be vapor-deposited, a coloring agent may be added to the coating material to form the coating resin layers 3, 3, for example, as a yellow resin layer. Even if the vapor-deposited metal is aluminum, it can be made to look like vapor-deposited gold foil. Further, when the coating resin layers 3, 3 are formed as patterned resin layers, it is possible to give a pattern change to the deposited metal.

Further, 4, 4 is a metal vapor deposited layer, which is formed on the coating resin layer 3, 3 when the coating resin layer 3, 3 is formed, and when such a resin layer is not formed, the above mold release layer. Formed on layers 2, 2 or base film 1. These metal vapor deposited layers 4, 4 are organically integrated as shown in FIG. is formed.

The metal to be vapor deposited in this metal vapor deposition layer includes aluminum, gold, silver, nickel, tin, zinc, etc., but is not particularly limited.

Further, as the adhesive, an epoxy resin adhesive is mainly used, but the adhesive is not limited to this adhesive, and for example, an isocyanate adhesive or the like may be used.

In addition, the flexibility imparted to the adhesive can be adjusted by adjusting the plasticizer blended in the adhesive, and the adhesive layer can be added to the two integrated metal-deposited layers 4, 4 according to the use of the metal-deposited foil. 5 gives flexibility (adhesiveness) or slightly hardness to adjust the degree of softness or hardness of the metal-deposited foil.

The metal-deposited foil of the present invention has an adhesive layer 5 as described above.
Since the two metal vapor deposited layers 4, 4 are organically integrated through the metal vapor deposited layer 4, the two metal vapor deposited layers 4, 4 are connected to each other, and the adhesive layer 5 serves as a cushion. result. Therefore,
Unlike conventional metal-deposited foils that have one or two layers, the metal-deposited foil of the present invention has the flexibility (stickiness) of stamped foil, and even if this metal-deposited foil is attached to a certain object, it will not crack. This prevents the foil from falling off in that area, allowing the foil to be permanently bonded.

Further, since the metal-deposited foil of the present invention is formed of two layers of metal-deposited foil 4, 4 with an adhesive 5 in between, it has the same weight and thickness as stamped foil. Therefore, when pasting the metal-deposited foil of the present invention, air can be easily expelled from the pasted surface of the foil, and the surface of the foil can be made uneven without creating minute air bubbles within the pasted surface of the foil. This allows for beautiful bonding without any problems. In addition, since it can be easily cut into a certain shape, it can be used as cut foil or wild hair, and it can also be used as a sandbag made by forming foil into particles, making it a very versatile metal. It can be called vapor-deposited foil.

Furthermore, since the metal-deposited foil of the present invention has a structure in which the two metal-deposited layers 4, 4 formed via the adhesive layer 5 are sandwiched between the two base materials 1, 1, the metal-deposited foil has an embossed part. It is possible to apply so-called embossing, which creates an uneven pattern such as depressions or depressions. That is, since the adhesive layer 5 serves as a cushion for the two metal vapor deposited layers 4, 4 and is protected by the two base materials 1, 1, the metal vapor deposited foil is pressed against the embossing roll. It is also possible to perform embossing without causing cracks, and the appearance and feel of the metal-deposited foil of the present invention can be made to look just like stamped foil.

Further, the above two base materials 1, 1 are made of plastic films, and the plastic films are made of different types, for example, Tetoron film and polypropylene film, so that the base materials 1, 1 are made of different materials. , 1 can have different degrees of releasability. Therefore, if one base material 1 is peeled off before using the metallized foil, and then peeled off when only the other base material 1 is used, the metallized foil can be used extremely conveniently. be able to.
