BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a partial vapor deposition transfer foil in which a transparent colored layer and a metal vapor deposition layer are laminated in a desired pattern.

[0002]

2. Description of the Related Art A partial vapor deposition transfer foil in which a transparent colored layer and a metal vapor deposition layer are laminated in a desired pattern has hitherto been formed by sequentially forming a release layer and a protective layer on one side of a plastic film, and then forming a release layer on the protective layer. A transparent colored layer is formed in a desired pattern, then a water-soluble resin layer is formed in a portion where the transparent colored layer does not exist, and then a metal vapor deposition layer is formed over the entire surface. The water-soluble resin layer and the metal deposition layer corresponding to the water-soluble resin layer were removed by dissolving the water-soluble resin layer, and then the adhesive layer was formed over the entire surface.

However, the partial vapor-deposited transfer foil in which the conventional transparent colored layer and the metal vapor-deposited layer are laminated in a desired pattern has an edge between the transparent colored layer and the water-soluble resin layer in the manufacturing process. Since it cannot be formed so as to be completely aligned, the edges of the transparent colored layer and the metal vapor deposition layer are not aligned after washing with water.

That is, when the edges of the transparent coloring layer and the water-soluble resin layer overlap, the edges of the transparent coloring layer and the metal deposition layer laminated in the desired pattern of the obtained partial vapor deposition transfer foil are metal. There is no vapor deposition layer and only the transparent coloring layer, and when the edges of the transparent coloring layer and the water-soluble resin layer are separated, a transparent coloring layer laminated in a desired pattern of the obtained partial vapor deposition transfer foil, At the edge with the metal vapor deposition layer, there is no transparent colored layer and only the metal vapor deposition layer is present. As described above, in the partial vapor deposition transfer foil in which the conventional transparent colored layer and the metal vapor deposition layer are laminated in a desired pattern, the edges of the transparent color layer and the metal vapor deposition layer do not coincide.

On the other hand, the order of formation of the transparent colored layer and the water-soluble resin layer is reversed, and after the water-soluble resin layer having a desired pattern is formed, the transparent colored layer is formed on the portion where the water-soluble resin layer does not exist. When it is formed so as to overlap the edge of the layer, it is possible to obtain a partial vapor deposition transfer foil in which the edges of the transparent colored layer and the metal vapor deposition layer are aligned. However, in such a case, since the conventional transparent colored layer is generally a relatively thick layer made of a resin having a thickness of 1 to 3 μm, water does not penetrate into the transparent colored layer at the time of washing with water, and the water-soluble Since the resin layer is also a simple water-soluble resin layer, the water-soluble resin layer does not dissolve in the portion where the edges of the water-soluble resin layer and the transparent colored layer overlap, and the edges of the transparent colored layer and the metal vapor deposition layer are flush with each other after washing with water. However, since the water-soluble resin layer remains under the transparent colored layer at the edge, the adhesiveness between the transparent colored layer and the protective layer at the edge is extremely weak. Is.

The present invention eliminates the above-mentioned drawbacks, the edges of the transparent colored layer and the metal vapor-deposited layer are aligned, and the adhesion between the transparent colored layer and the protective layer at the edge is extremely strong.
The present invention provides a partial vapor deposition transfer foil in which a transparent colored layer and a metal vapor deposition layer are laminated in a desired pattern.

According to the present invention, a release layer is formed on one surface of a plastic film, a protective layer is formed on the release layer, and a porous water-soluble resin layer is formed in a desired pattern on the protective layer. Then, from the top of the water-soluble resin layer, at least in a portion where the water-soluble resin layer does not exist, the thickness is 0.05 to 0.5 μm.
m to form a transparent colored layer, and then form a metal vapor deposition layer over the entire surface of the transparent colored layer. Further, after the metal vapor deposition layer is formed, the metal layer is washed with water to dissolve the water-soluble resin layer. Of a water-soluble resin layer and a transparent colored layer and a metal vapor deposition layer corresponding to the water-soluble resin layer, and thereafter, an adhesive layer is formed over the entire surface of the metal vapor deposition layer, transparent coloring It is a partial vapor deposition transfer foil in which the edges of the layer and the metal vapor deposition layer are aligned.

As the plastic film, those conventionally used for transfer foil such as polyester film can be used. A release layer and a protective layer are sequentially formed on one surface of the plastic film with an appropriate resin. A water-soluble resin layer in a porous state is formed in a desired pattern on the protective layer, and then the thickness of the water-soluble resin layer is 0.05 to 0. A 5 μm transparent colored layer is formed.

According to the present invention, the order of forming the transparent colored layer and the water-soluble resin layer is reversed from that of the prior art, and the transparent colored layer is formed after the water-soluble resin layer is formed, and the water-soluble resin layer is porous. And the thickness of the transparent colored layer is 0.05
It has a great feature in a total of four points, that is, it is very thin as 0.5 μm and that these three points are combined.

If the thickness of the transparent colored layer formed after the formation of the water-soluble resin layer is made as thin as 0.05 to 0.5 μm,
The transparent colored layer is a thin film in the portion where the water-soluble resin layer does not exist below the transparent colored layer, but in the portion where the water-soluble resin layer exists below the transparent colored layer, the transparent colored layer is Since the layer is in a porous state, the resin of the transparent colored layer is not absorbed to form a film in the porous portion, or even if a film is formed, it becomes an extremely thin and porous state, so the water is transparently colored during washing with water. It penetrates the layer and dissolves the water-soluble resin layer below the transparent colored layer.

Then, by dissolving the water-soluble resin layer below the transparent colored layer, the water-soluble resin layer below the transparent colored layer, and the transparent colored layer and the metal deposition layer corresponding to the water-soluble resin layer are formed. As a result, the edges of the transparent colored layer and the metal vapor deposition layer are aligned with each other after washing with water, and the water-soluble resin layer does not remain on the edges.

The water-soluble resin layer in a porous state may naturally become a porous state when the water-soluble resin layer is formed, depending on the resin used, but it is not necessary to form the water-soluble resin layer. When it does not become
A porous water-soluble resin layer can be formed by adding an extender pigment such as silicon oxide.

The thickness of the transparent colored layer is 0.05 to 0.5 μm.
And The transparent colored layer becomes a thin film in the part where the water-soluble resin layer does not exist under the transparent colored layer, and the transparent colored layer does not form a film in the part where the water-soluble resin layer exists under the transparent colored layer or the film is not formed. In order to obtain an ultrathin and porous state even when formed, the thickness of the transparent colored layer is not necessarily constant depending on the type and concentration of the resin used in the transparent colored layer. However, if the thickness of the transparent colored layer is set to 0.05 to 0.5 μm, the transparent colored layer becomes a thin film in a portion where the water-soluble resin layer does not exist below the transparent colored layer, and the transparent colored layer is formed below the transparent colored layer. In the portion where the water-soluble resin layer is present, the transparent colored layer does not form a film or becomes extremely thin and porous even if a film is formed.

In particular, the thickness of the transparent colored layer is 0.1 to 0.3.
When the thickness is set to μm, the transparent colored layer becomes a thin film in the portion where the water-soluble resin layer does not exist below it, regardless of the type and concentration of the resin used in the transparent colored layer, and the portion where the water-soluble resin layer exists below. In the case, the transparent colored layer does not form a film or becomes extremely thin and porous even if a film is formed.

When the thickness of the transparent colored layer is less than 0.05 μm, it is too thin and the colored color is not clearly visible. When the thickness of the transparent colored layer is more than 0.5 μm, it is too thick and water does not penetrate into the transparent colored layer during washing with water.

The transparent colored layer preferably has a thickness of 0.1 to 0.3 .mu.m in order to bring out the color of the transparent colored layer clearly and to allow water to sufficiently penetrate into the transparent colored layer during washing with water. When the transparent colored layer has a thickness of 0.1 to 0.3 μm,
As described above, regardless of the type and concentration of the resin used for the transparent colored layer, a thin film is formed in the portion where the water-soluble resin layer is not present below, and the transparent colored layer is formed in the portion where the water-soluble resin layer is present below. Not only does not form a film, or even if a film is formed, it becomes not only an extremely thin and porous state, but also a colored color can be produced clearly and water sufficiently penetrates the transparent colored layer at the time of washing with water. .

The transparent colored layer of the present invention may be formed over the entire surface of the water-soluble resin layer, but when it is formed partially, it is formed at least in a portion where the water-soluble resin layer does not exist. In practice, it is not possible to form the transparent colored layer so that the edges of the transparent colored layer and the water-soluble resin layer are completely aligned in the manufacturing process. Alternatively, the water-soluble resin layer is partially formed with the edges overlapping with each other.

The metal vapor deposition layer is formed over the entire surface of the transparent colored layer by vacuum vapor deposition, sputtering, ion plating or the like. The thickness of the metal vapor deposition layer is not particularly limited, and may be, for example, a level of exhibiting a beautiful metallic luster of 300 to 600 Å, or a level of semitransparent of 100 to 300 Å. The adhesive layer does not have to be formed in particular, but may be formed over the entire surface after the transparent colored layer and the metal vapor deposition layer are laminated in a desired pattern by washing with water. When the adhesive layer is not formed, when the partial vapor deposition transfer foil of the present invention is transferred, the adhesive layer can be formed on the transfer target and transferred. Even if the adhesive layer is formed, it is needless to say that the adhesive layer may be formed on the transfer target, if necessary.

In the present invention, an appropriate printed pattern may be previously formed on the protective layer with a transparent or opaque colored resin before the water-soluble resin layer is formed. Included in the invention. By doing so, a beautiful design effect can be obtained by this printed pattern and the pattern of the transparent colored layer and the metal vapor deposition layer which are laminated so that the edges formed later coincide with each other.

Further, according to the present invention, regardless of whether or not an appropriate printed pattern is formed in advance on the protective layer with a transparent or opaque colored resin, before forming the water-soluble resin layer,
An anchor coat layer may be preliminarily formed on the entire surface according to the purpose of imparting heat resistance and the like, and of course, such a thing is also included in the present invention.

EXAMPLE A release layer was formed on one surface of a plastic film having a thickness of 25 μm by a gravure coating method using an acrylic resin, and an acrylic-urethane resin was used on the release layer by a gravure coating method. A protective layer is formed, and a water-soluble resin layer having a desired pattern is formed on the protective layer by using a polyvinyl alcohol resin to which silicon oxide is added as a water-soluble resin, and then, at least the water-soluble resin layer is not present. A transparent colored layer having a thickness of 0.2 μm is formed on the portion, and then the entire thickness is 450 by vacuum deposition using Al.
By forming a metal vapor deposition layer of Å, and further after washing the metal vapor deposition layer to dissolve the water-soluble resin layer, a water-soluble resin layer, and a transparent colored layer corresponding to the water-soluble resin layer After removing the metal deposition layer, the entire surface is vinyl chloride
An adhesive layer was formed by a reverse roll coating method using a resin obtained by blending a vinyl acetate resin and an acrylic resin to obtain a partially vapor-deposited transfer foil of the present invention in which the edges of the transparent colored layer and the metal vapor-deposited layer were aligned. .

[0022]

Since the present invention is constructed as described above,
The edges of the transparent colored layer and the metal vapor deposition layer laminated in a desired pattern are completely coincident with each other, unlike the conventional partial vapor deposition transfer foil having only the transparent color layer or the metal vapor deposition layer. Further, since the water-soluble resin layer does not exist under the transparent colored layer at the edges of the transparent colored layer and the metal deposition layer laminated in a desired pattern, the adhesion between the transparent colored layer and the protective layer at the edge is extremely strong.
