Description

[Detailed description of the invention] <Industrial application field> This invention is used to impart design properties to the surfaces of plastic molded products, ceramic molded products, metal molded products, glass molded products, etc. using colored ink patterns, etc. The present invention relates to a transfer foil that is used when printing, printing, etc. to provide functionality with a conductive circuit pattern, etc.

More specifically, the present invention relates to a transfer foil that does not cause foil spillage when the transfer foil is slit to a width suitable for transfer printing and has excellent suitability for transfer printing.

<Problems to be solved by conventional technology and inventions> Conventionally, transfer foils are made by applying
It is known that a transfer layer consisting of a release layer, a pattern layer, an adhesive layer, etc. is laminated.

Normally, it would be uneconomical to manufacture such transfer foil with the width used for transfer printing, so products are manufactured with a wide width and this is adjusted to the size of the object to be transferred. After slitting to the appropriate width, transfer printing is performed.

However, in this case, there was a drawback that the slit portion of the transfer foil was hit by the blade during slitting, causing the foil to spill, that is, the transfer layer to be peeled off from the base film. This is because the separation between the base film of the transfer foil and the transfer layer is excellent not only in the part where the pattern to be subjected to transfer printing is formed but also in the part not to be subjected to transfer printing. This drawback was more pronounced when the total transfer layer was thicker, such as when there were many pattern layers as the transfer layer, when it was necessary to provide a vapor-deposited layer as the pattern layer, or when there were many functional layers.

As a result, there was a problem in that small pieces of foil spilled during the transfer printing process entered the space between the transferred object and the transfer layer as dust, impairing the design and functionality.

<Means for Solving the Problems> In view of the above problems, the inventors of the present invention have conducted various research and considerations, and as a result, have finally completed the present invention. In other words, the present invention is based on the base film 1.
In a transfer foil on which a transfer layer 5 consisting of a release layer 2, a pattern layer 3, an adhesive layer 4, etc. is laminated, a foil that does not separate between the base film 1 and the transfer layer 5 is placed in the slit portion of the transfer foil. The spill prevention layer 6 is
This is a transfer foil characterized in that it is provided between a base film 1 and a transfer layer 5.

Hereinafter, the present invention will be explained in more detail using the drawings. It should be noted that the drawings are drawn in an exaggerated manner, ignoring the relative dimensional relationships of the constituent elements, for clarity of illustration.

FIG. 1 is a schematic enlarged sectional view showing one embodiment of a transfer foil according to the present invention.

1 is a base film, 2 is a release layer, 3 is a pattern layer,
4 is an adhesive layer, 5 is a transfer layer, and 6 is a foil spill prevention layer.

The base film 1, release layer 2, pattern layer 3, and adhesive layer 4 may be formed using the same materials and methods as those used for manufacturing known transfer foils.

In this invention, the characteristic foil spill prevention layer 6
After the transfer foil is manufactured, it is formed at a portion where it is slit to an appropriate width, and is formed between the base film 1 and the transfer layer 5.

FIG. 2 is a perspective view showing an embodiment of the transfer foil according to the present invention.

The foil spill prevention layer 6 is made of ink that does not easily separate from the base film 1 and the transfer layer 5, and is formed into a strip slightly wider than the slitting area.
For example, it may be formed with a width of 5 mm and a thickness of 0.1 to 2 μm. Examples of resin binders that can be used in this ink include acrylic resin, vinyl resin, urethane resin, and polyester resin.

Next, examples will be given and explained.

<Example> A foil spill prevention layer was provided in a band shape on a polyester film using an ink consisting of the following composition 1,
A release layer was provided on the entire surface using an ink made of Composition 2, a pattern layer was provided on the entire surface using an ink made of Composition 3, and an adhesive layer was provided on top of that using an ink made of Composition 4. . (All parts are by weight.) Composition 1: Acrylic/polyester resin 10 parts Toluene 45 parts Methyl ethyl ketone 45 parts Composition 2: Acrylic resin 10 parts Toluene 45 parts Methyl ethyl ketone 45 parts Composition 3: Acrylic/vinyl resin 15 parts Pigment 30 parts Toluene 35 parts Methyl ethyl ketone 20 parts Composition 4: Acrylic resin 15 parts Toluene 40 parts Ethyl acetate 45 parts Next, when the part provided with the foil spill prevention layer was slit, no foil spill occurred.

<Effects of the invention> Since the present invention is constructed as described above, it has the following effects. That is, when the transfer foil according to the present invention is slit to an appropriate width after being manufactured, if the portion where the foil spill prevention layer is provided is slit, delamination will not occur between the base film and the transfer layer. As a result, during the transfer printing process, small pieces of foil do not get trapped between the transfer layer and the transferred object as dust, allowing the transfer printing process to be carried out without compromising design or functionality. It can be carried out. Moreover, since the film layer is larger in the area where the foil spill prevention layer is provided than in other areas, when the transfer foil is rolled up after manufacturing,
Since it is difficult to add anything to the pattern layer, it is difficult to cause blocking.

Therefore, the present invention is of extremely high practical value.
