Description

Transfer film structure and three-dimensional transfer product

The present invention relates to a transfer film structure and a transfer product, and more particularly to a transfer film structure and a three-dimensional transfer product comprising a light shielding 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. Then, an ink layer is disposed on the soft coating opposite to the side of the release agent layer, and an adhesive layer is disposed on the ink layer opposite to the side of the soft coating layer, and finally a transfer film structure is prepared. . After the transfer film structure is fixed to the surface of the object through the adhesive layer and the release agent layer is removed, a three-dimensional transfer pattern is formed on the surface of the object.

However, after the removal of the release agent layer, the release agent often leaves a release agent on the three-dimensional transfer pattern, and the release agent cannot be completely removed, which affects the appearance of the three-dimensional transfer pattern. . Therefore, how to solve the shortcomings of the existing transfer film structure due to the release agent has become a goal of current research.

Therefore, the first object of the present invention is to provide a transfer film structure. The transfer film structure does not leave a release agent on the three-dimensional transfer pattern formed on the surface of an object.

Therefore, the novel transfer film structure comprises an elastic film substrate layer, a template layer, a first light shielding layer, a second light shielding layer, a filling layer, a dark reaction 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 light shielding layer is formed on the elastic film substrate layer with a second pattern complementary to the first pattern and is formed by an ultraviolet light absorbing ink, and the first light shielding layer is on the same plane as the template layer.

The second light shielding layer is formed on the template layer in the first pattern and formed of ultraviolet light absorbing ink.

The filling layer is formed on the second light shielding layer in the first pattern and formed of a transparent ink.

The dark reaction layer is formed on the filling layer in the first pattern.

The first pattern layer is formed on the first light shielding layer by the second pattern and is formed of an oil-soluble paint, and the first pattern layer is in contact with the second light shielding layer, the filling layer and the dark reaction layer.

The fixed layer is on the dark reaction layer and the first pattern layer.

Further, the present invention has a second object of providing a three-dimensional transfer product which does not leave a release agent on its three-dimensional transfer pattern.

Therefore, the novel three-dimensional transfer product comprises an object, a fixed layer, a dark reaction layer, a third pattern sublayer, a filling layer, a second pattern sublayer and a first pattern sublayer.

The fixing layer is attached to the surface of the article.

The dark reaction layer is positioned on the pinned layer in a first pattern.

The third pattern sublayer is formed on the fixed layer with a second pattern complementary to the first pattern and is formed of an oil-soluble coating, and the third pattern sublayer is on the same plane as the dark reaction layer.

The filling layer is overlaid on the dark reaction layer in the first pattern and formed of a clear ink.

The second pattern sublayer overlies the third pattern sublayer with the second pattern and is formed of an oil soluble coating, the second pattern sublayer being on the same plane as the filling layer.

The first pattern sublayer is covered on the second pattern sublayer by the second pattern and is formed by an oil-soluble paint, and the first pattern sublayer, the second pattern sublayer and the third pattern sublayer are jointly defined a first pattern layer.

The effect of the novel is that the transfer film structure of the present invention is configured such that the first light-shielding layer and the second light-shielding layer are disposed so as to be attached to the surface of an object, and only the ultraviolet light is required to make the first a light shielding layer, the second light shielding layer, the template layer and the elastic film substrate layer can be easily removed from the filling layer and the first pattern layer, and the existing transfer film structure is attached to an object The technique of removing the release agent layer after the surface is different. Therefore, the transfer film structure of the present invention does not leave a release agent on the three-dimensional transfer pattern formed on the surface of the article, that is, on the filling layer and the first pattern layer.
