Utility model content:

The purpose of this utility model is to provide a light-curable transfer film with solvent-resistant and scratch-resistant functions and better quality of printed pictures and texts, aiming at the deficiencies of the prior art.

In order to achieve the above object, the utility model adopts the following technical solutions:

A light-curable transfer film, comprising a base film layer, including a UV release layer, a UV varnish inner protective layer, a bridging layer and an ink decoration layer, and the connection sequence between the layers is the base film layer, the UV release layer, and the UV release layer. Type layer, UV varnish inner protective layer, bridging layer and ink decoration layer;

Wherein, the exposed surface of the ink decoration layer is also sequentially connected with a bridging layer and an outer protective layer;

The exposed surface of the ink decoration layer is connected with an adhesive layer;

The exposed surface of the outer protective layer is connected with an adhesive layer.

The beneficial effects of the utility model are: the utility model adopts a special structure including a base film layer, a UV release layer, an ink decoration layer, a UV varnish protective layer and a bridging layer, and makes the UV varnish layer and the bridging layer The ink decorative layers are well cross-linked, thereby improving the connection quality between UV varnish and decorative ink, making the quality of the decorative graphics of the entire transfer film more perfect, more solvent-resistant, and more scratch-resistant. In particular, the special structure of the utility model determines that each layer is mainly dried and solidified by light in the production process, which greatly improves the speed of drying and solidification, thereby greatly improving the production efficiency.

Accompanying drawing 1 is the structural representation of the first embodiment of the utility model;

Accompanying drawing 2 is the structural representation of the second embodiment of the utility model;

Accompanying drawing 3 is the structural representation of the utility model third kind of embodiment;

Accompanying drawing 4 is the structure diagram of the fourth embodiment of the utility model.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model will be further described,

See Fig. 1, this is the first embodiment of the present utility model, a light-curable transfer film, its layer structure is successively base film layer 1, UV release layer 4, inner protective layer 2a, bridging layer 3a and ink decoration layer 5; wherein the base film layer 1 is mainly made of PET (polyester), the inner protective layer 2a can well protect the stability of the UV varnish in the release layer, and is decorated with the ink through the bridging layer 3a Layer 5 is cross-linked, thereby improving the connection quality between UV varnish and decorative ink, making the quality of the decorative graphics of the entire transfer film more perfect, more solvent-resistant, and more scratch-resistant.

During transfer printing, first apply a layer of adhesive resin on the outer surface of the decorative layer 5 of the transfer film by machinery, then cover the transfer film as a whole on the receiving object, then heat and press, and finally tear off the base film layer 1. The perfect graphics and text on the ink decoration layer 5 are displayed on the receiving object.

See Fig. 2, this is the second embodiment of the present utility model, a light-curable transfer film, its layer structure is successively base film layer 1, UV release layer 4, inner protective layer 2a, bridging layer 3a And the ink decoration layer 5, and a bridging layer 3b and an outer protective layer 2b are sequentially added outside the ink decoration layer 5; wherein the base film layer 1 is mainly made of PET (polyester).

During transfer printing, first coat a layer of adhesive resin on the outer surface of the decorative layer 2b of the transfer film by machinery, then cover the transfer film as a whole on the receiving object, then heat and press, and finally tear off the base film layer 1 , the perfect graphics and texts of the ink decoration layer 5 are displayed on the receiving object.

See Fig. 3, this is the third embodiment of the present utility model, different from the first embodiment, the exposed surface of the ink decoration layer 5 in this embodiment is connected with a hot-melt adhesive layer 6, wherein the hot-melt The adhesive layer 6 is optional, and the difference from the first embodiment is that when transferring, the first embodiment needs to apply a layer of adhesive resin on the outer surface of the transfer film by machinery, while this embodiment The structure of the method itself has an adhesive layer 6, and there is no need to coat a layer of adhesive on the substrate in the transfer printing, and a thermal transfer film with a hot melt adhesive layer 6 is added to the outermost surface. The film not only has a good decorative effect, but also increases the friction resistance, fastness and adhesion of the transferred finished product.

See Fig. 4, this is the fourth embodiment of the present utility model, different from the second embodiment, the exposed surface of the outer protective layer 2b in this embodiment is provided with a hot melt adhesive layer 6, wherein the hot melt The adhesive layer 6 is optional, and the difference from the second embodiment is that when transferring, in the second embodiment, a layer of adhesive resin needs to be applied on the outer surface of the transfer film by machinery, while the structure of the present embodiment There is an adhesive layer 6 in the center itself, and there is no need to coat a layer of adhesive on the substrate in the transfer printing, and a thermal transfer film with a hot melt adhesive layer added to the outermost surface, the transfer film not only has It has a good decorative effect, and it can also increase the friction resistance, fastness and adhesion of the transferred finished product.

The production process of the light-fixed transfer film is mainly based on the characteristics of UV varnish. In the whole process, each additional layer is dried and fixed by ultraviolet light irradiation, which can be quickly cured to form a film by ultraviolet light irradiation. , with high gloss, high hardness, no pollution, and has excellent weather resistance, wear resistance, solvent resistance; this not only greatly improves work efficiency, but also optimizes the working environment.

The above is only a preferred embodiment of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent application scope are all included in the utility model patent application scope .
