The present invention relates to a transfer film structure, and more particularly to a transfer film structure comprising a release agent layer.

In order to increase the aesthetic appearance of the article, there are various transfer films which can be applied to the surface of an object and have various transfer patterns, such as a transfer film which can be attached to an electronic product casing such as a mobile phone or a notebook computer. . However, most of the patterns on the transfer film are limited to the planar transfer pattern, and are not capable of producing a three-dimensional transfer pattern having a three-dimensional touch.

At present, a transfer film structure capable of producing a three-dimensional transfer pattern on an object has been developed. The transfer film structure is prepared by first providing a release agent layer and providing a soft coating layer on the release agent layer.

However, the transfer film structure obtained by the foregoing method is fixed to the surface of an object through the adhesive layer and the three-dimensional transfer product formed by removing the release agent layer, and the three-dimensional transfer pattern formed on the surface of the object is formed. Still not fine enough and lack of embossing. Therefore, how to solve the shortcomings of the aforementioned transfer film structure has become a direction for research and development.

Therefore, the object of the present invention is to provide a transfer film structure. The transfer film structure is capable of forming a fine and embossed three-dimensional transfer pattern on the surface of an object.

Therefore, the novel transfer film structure comprises an elastic film substrate layer, a template layer, a first release agent layer, a second release agent layer, a first pattern layer and a fixed layer.

The template layer is formed on the elastic film substrate layer in a first pattern and formed of a coating material.

The first release agent layer is formed on the elastic film substrate layer in a second pattern complementary to the first pattern and on the same plane as the template layer.

The second release agent layer is formed on the template layer in the first pattern.

The first pattern layer is formed on the first release agent layer in the second pattern and is formed of an oil-soluble paint. The first pattern layer and the second release agent layer are on the same plane.

The fixed layer is on the second release agent layer and the first pattern layer.

The effect of the novel is that the transfer film structure of the present invention comprises the first release agent layer on the same plane as the template layer, and is formed on the template layer and is in the same layer as the first pattern layer. a second release agent layer on the plane, and then, when the transfer film structure of the present invention is fixed to the surface of an object and the elastic film substrate layer, the template layer, and the first and second release agent layers are removed, A fine and embossed three-dimensional transfer pattern (i.e., the first pattern layer) can be formed on the surface of the article.
