The scope of the patent for the present invention shall be determined by the scope of patent application attached hereafter.

As shown in FIG. 1, it is a schematic diagram of an inkjet image transfer sticker 1 according to a first embodiment of the present invention. The inkjet image transfer sticker 1 includes a substrate 10 and an inkjet composite layer 12 And the transfer film 14, the inkjet composite layer 12 is formed on the substrate 10 and part of the surface of the substrate 10 is exposed, and the transfer film 14 is attached to the inkjet composite layer 12 and the substrate 10. Since the inkjet composite layer 12 exposes part of the surface of the substrate 10, the transfer film 14 can contact the inkjet composite layer 12 and the substrate 10 at the same time. In a preferred embodiment, the substrate 10 may be a release paper made of polyethylene terephthalate (PET).

As also shown in FIG. 1, in the first embodiment of the present invention, the inkjet composite layer 12 may be a multilayer stacked layer including a UV sensitive adhesive layer 122, a UV pattern layer 124 and a UV varnish layer 126. The inkjet composite layer 12 can be formed by spraying sequentially on the surface of the substrate 10 using an inkjet process. Therefore, the sides of the inkjet composite layer 12 can be roughly aligned with each other, exposing the surface of the substrate 10 below. In other words, the sides of the UV sensitive adhesive layer 122, the UV pattern layer 124, and the UV varnish layer 126 may be substantially aligned with each other, as shown in FIG. 1. In a preferred embodiment, the UV sensitive adhesive layer 122, the UV pattern layer 124 and the UV varnish layer 126 may be UV sensitive materials, which can be cured by exposure to UV light. Therefore, it is more convenient in the manufacturing process. The above-mentioned UV varnish layer 126 can be made of a transparent material, so that the underlying pattern layer 124 can be clearly displayed, and it can also be used as a protective layer to avoid scratches on the UV pattern layer 124.

In the inkjet pattern transfer sticker 1 in the first embodiment of the present invention, the UV sensitive adhesive layer 122 may be sprayed locally on the surface of the substrate 10. The surface of the transfer film 14 facing the substrate 10 may have an adhesive layer (not shown), so that the transfer film 14 can be attached and adhered to the surface of the UV varnish layer 126 and the substrate 10. In a preferred embodiment In this case, the adhesive force between the transfer film 14 and the UV varnish layer 126 may be greater than the adhesive force between the UV-sensitive adhesive layer 122 and the substrate 10, so that the substrate 10 can be smoothly transferred from the inkjet sticker during transfer. 1 Peel and remove.

Next, FIGS. 2 to 5 are schematic diagrams showing the manufacturing process of the inkjet pattern transfer sticker according to the first embodiment of the present invention. As shown in FIG. 2, a substrate 10 is provided, and a UV-sensitive adhesive layer 122 is locally sprayed on the surface of the substrate 10 by the inkjet head 16. In an embodiment, the liquid of the UV-sensitive adhesive layer 122 may be sprayed first, and then, in the same manufacturing process, a UV light (not shown) is used to irradiate the liquid of the UV-sensitive adhesive layer 122 to cure it to form UV Induction glue layer 122.

As shown in FIG. 3, next, the inkjet head 16 sprays a UV pattern layer 124 on the UV sensitive adhesive layer 122. In one embodiment, ink of any color can be sprayed from the inkjet head 16, such as white (W), cyan (C), magenta (M), yellow (Y), and black (K), etc., to UV sensitive glue On the layer 122, after spraying, UV light is immediately irradiated to cure it, and the UV pattern layer 124 is formed. After the UV pattern layer 124 is formed, the inkjet head 16 is used to spray a UV varnish layer 126 on the UV pattern layer 124, as shown in FIG. 4. Similarly, after the inkjet head 16 sprays the liquid of the UV varnish layer 126, it immediately irradiates UV light to cure it to form the UV varnish layer 126.

2 to 4 show the inkjet process for forming the inkjet composite layer 12. It can be understood that the multi-layer stack of the inkjet composite layer 12 is a composite layer formed by sequentially spraying, curing, and stacking using an inkjet process. Here a process can refer to a process worker In this process, multiple repeated process steps can be performed without changing equipment or other process steps. For example, in this embodiment, the inkjet equipment is also used for multiple spraying, curing, etc., without the need to change other equipment to complete the preparation of the inkjet composite layer. Because one inkjet process can be used to prepare the inkjet composite layer 12 of the UV sensitive adhesive layer 122, the UV pattern layer 124 and the UV varnish layer 126. Therefore, the manufacturing process is more convenient and fast in a traditional way. Furthermore, since the multi-layer stacks are formed by the same inkjet process, the sides of the multi-layer stacks may be substantially aligned with each other, exposing the surface of the substrate 10 below. In addition to saving material cost, no inkjet material such as a UV-sensitive adhesive layer is formed on the surface of the exposed substrate 10, and more importantly, the exposed surface of the substrate 10 is beneficial to the subsequent continuous process. For example, it can be used as a roller aisle for continuous equipment to avoid glue sticking to process equipment.

FIG. 5 shows that after the inkjet composite layer 12 is formed, the transfer film 14 is attached to the surface of the inkjet composite layer 12 and the substrate 10. As shown in FIG. 5, the adhesive surface of the transfer film 14 may be placed toward the substrate 10 and the inkjet composite layer 12, and then attached. When attaching, it can also be applied to the surface of the transfer film 14, as shown by the arrow in FIG. 5, in the direction of the substrate 10 and the inkjet composite layer 12, so that the transfer film 14 can be fully pressed. It is bonded to the substrate 10 and the inkjet composite layer 12. In one embodiment, the attaching process of the transfer film 14 may be a roll-to-roll continuous process. Because the inkjet composite layer 12 of the inkjet pattern transfer sticker 1 of the first embodiment of the present invention is The sides can be aligned with each other to expose part of the surface of the substrate 10, which can avoid the problem of equipment sticking caused by the glue material, and is more conducive to the continuous roll-to-roll process.

6 to 8 show schematic diagrams of the transfer method of the inkjet image transfer sticker according to the first embodiment of the present invention. First, as shown in FIG. 6, the substrate 10 as a release paper is peeled off and removed from the inkjet transfer sticker. As described above, the adhesive force between the transfer film 14 and the UV varnish layer 126 can be greater than the adhesive force between the substrate 10 and the UV sensitive adhesive layer 122, so the substrate 10 can be peeled off and removed smoothly, as shown in FIG. 6 The arrow shows. It is worth noting that the UV sensitive adhesive layer 122 of the inkjet image transfer sticker in the first embodiment of the present invention is formed corresponding to the UV pattern layer 124 and the UV varnish layer 126, so when the substrate 10 is peeled off, the substrate 10 10 There will be no problem of glue residue on the surface.

FIG. 7 shows the inkjet image transfer sticker with the substrate 10 removed in FIG. 6 being attached to the target 18, and then, after the image transfer sticker is firmly adhered to the target 18, the transfer film 14 is attached Peel off and remove from the inkjet image transfer sticker, as shown in Figure 8. When attaching to the target 18, a slight pressure can be applied to the surface of the transfer film 14 so that the UV-sensitive adhesive layer 122 can be adhered to the target 18 more firmly. The UV-sensitive adhesive layer 122 in this embodiment may preferably also be an adhesive material that can increase the adhesion between the target 18 and the target 18 when pressure is applied from the outside. In FIG. 8, the adhesive force between the UV sensitive adhesive layer 122 and the target 18 can be relatively greater than the adhesive force between the transfer film 14 and the UV varnish layer 126, so the transfer film 14 can be peeled off and removed. As mentioned above, the UV varnish layer 126 can be used as a protective layer to avoid scratching the transfer The image on the target 18.

Fig. 9 shows an inkjet image transfer sticker 1 according to a second embodiment of the present invention. In the second embodiment, the functions and forming methods of similar elements, and the transfer method can be referred to the corresponding description of the first embodiment, which will not be repeated here. The biggest difference between the second embodiment and the first embodiment is the inkjet composite layer 12. In the second embodiment, a color colloidal composite layer 123 is used instead of the UV sensitive adhesive layer 122. Similarly, on the surface of the substrate 10, use an inkjet machine to spray a composition of adhesive material such as white pigment ink and UV-sensitive glue, and then irradiate UV light to make the color colloidal composite layer 123 Curing. After that, the UV pattern 124 and the UV varnish layer 126 are sequentially formed according to the above description, and the transfer film 14 is attached. Preferably, the adhesive force between the transfer film 14 and the UV varnish layer 126 may be greater than the adhesive force between the substrate 10 and the color colloidal composite layer 123. In one embodiment, the color colloidal composite layer 123 preferably uses a UV sensitive material.

In the second embodiment, the white pigment ink and UV sensitive glue can be mixed and formulated, and then sprayed through the inkjet head. Only one step can be used to complete a composite layer that has both adhesive layer and white color layer that can increase image contrast. This method can not only reduce manufacturing steps and reduce production costs, but also increase the efficiency of manufacturing and production and the contrast of transferred images.

It should be noted that the above embodiments can be freely combined according to needs. The above description and drawings are only preferred embodiments of the present invention. It should be pointed out that for the present invention Those skilled in the art with ordinary knowledge can make various improvements and modifications without departing from the principle and spirit of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. Therefore, the scope of protection of the present invention should be subject to the scope of subsequent patent applications.
