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) the release layer 2 is formed excluding the slit portion; b) Base film 1 on which the release layer 2 is formed
On top, base film 1, release layer 2 and pattern layer 3
This transfer foil is characterized in that a foil spill prevention layer 6 that does not peel between the layers is formed so as to cover at least a portion where the peeling layer 2 is not formed.

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 an 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 release layer 2, which is a feature of the present invention, is formed excluding the slit portion of the transfer foil. That is, after the transfer foil is manufactured, it is formed except for the portions to be slit to an appropriate width.

Further, the foil spill prevention layer 6, which is a feature of the present invention, is formed on the base film 1 on which the release layer 2 is formed, so as to cover at least the portion where the release layer 2 is not formed.

The foil spill prevention layer 6 comprises a base film 1,
It is preferable to form the layer with a thickness of 0.1 to 2 μm using an ink that does not easily separate the layers from the release layer 2 and pattern layer 3. Examples of resin binders that can be used in this ink include acrylic resin, vinyl resin, urethane resin, and polyester resin.

The foil spill prevention layer 6 may be formed on the entire surface of the base film 1 on which the release layer 2 is formed.

The base film 1, release layer 2, pattern layer 3, and adhesive layer 4 are preferably formed of the same materials as those used for manufacturing known transfer foils.

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

Next, examples will be given and explained.

<Example> A release layer was provided on a polyester film except for the slit portion using an ink consisting of the following composition 1, and a foil spill prevention layer was provided on the entire surface using an ink consisting of composition 2, and then A pattern layer is provided using an ink consisting of composition 3, and on top of that a pattern layer is formed using an ink consisting of composition 3.
An adhesive layer was provided using an ink consisting of: All "parts" here indicate "parts by weight."

Composition 1: Acrylic resin 10 parts Toluene 45 parts Methyl ethyl ketone 45 parts Composition 2: Acrylic/polyester 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 where the release layer was not provided was slit, no foil spillage 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, there is no delamination between the base film and the transfer layer, so there is no foil spillage, and as a result, the transfer Transfer printing processing can be performed without impairing design and functionality, since small pieces of foil do not enter as dust between the transfer layer and the transferred object during printing processing. In addition, the portion where the foil spill prevention layer is formed has a larger film layer than other portions, and when the transfer foil is manufactured and then rolled up, the pattern layer is less likely to be added to the transfer foil, so blocking is less likely to occur.

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