Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the present specification, the terms "upper", "lower", "left", "right", "middle", and the like are used for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.

As shown in fig. 1 and 2, the present embodiment provides an in-mold transfer material, comprising a carrier sheet 20, a protective layer 21 formed on the carrier sheet 20, and a color design layer 22 formed on the protective layer 21, wherein the carrier sheet 20 and the protective layer 21 are directly attached and contacted,

the protective layer 21 functions to scrape off or peel off the color design layer 22, and it should be noted that the side where the carrier sheet 20 is disposed is an outer surface when the in-mold transfer material is adhered. Therefore, in order to secure the effect of adhesion, an adhesive layer 23 for adhesion is provided on the surface of the color design layer 22.

In the above, the protective layer in the transfer material is made of an ultraviolet curing material, and may be made of a thermal curing material in addition to the ultraviolet curing material. The adhesion of the two forms of material will be reduced after hardening, which may be performed before or after shaping itself.

When the hardened materials are adhered to each other, the protective layer is hardened and also serves as a release layer in function, so that the carrier sheet is torn off from the transfer printing material in an auxiliary manner.

Compared with the prior art, one of the advantages of the embodiment is that the carrier sheet on the transfer material can be torn off without arranging release paper.

In layers, the entire work of the in-mold transfer material in the present embodiment is completed after the adhesive layer is completed. Next, in order to enhance the effect of the transfer material in the present embodiment, further improvements and limitations are made between the above structures, which are specifically as follows:

the end parts of the bottom surface of the carrier sheet 20 and the top surface of the adhesive layer 23 are both provided with a concave groove 10, one side of the concave groove 10, which is positioned on the end surface, is lower than the other side, one side of the concave groove 10, which is positioned away from the end surface, is provided with a fitting groove 11, an encapsulation layer 12 for sealing the end surface is fixedly bonded in the concave groove 10, and the surface of the encapsulation layer 12 is also provided with a protection layer 21.

The encapsulation layer 12 can completely wrap the end face, so that the transfer material is corroded from the end face in the preservation process of the surface, the efficacy of the transfer material is changed, and the original function of the transfer material is influenced. The concave groove and the fitting groove are arranged so that the packaging layer can not protrude out of the whole transfer printing material, the surface of the whole transfer printing material is smooth as normal, and the normal use and the attractiveness of the transfer printing material can not be influenced.

In addition, in order to make the connection relationship between the slide 20 and the protective layer 21 tighter and prevent the slide from sliding mutually or prevent the protective layer from being attached poorly after the slide is torn off, a positioning threshold 30 and a positioning groove 31 which are engaged with each other are respectively arranged on the contact surfaces of the slide 20 and the protective layer 21, and the lengths of the positioning threshold 30 and the positioning groove 31 are both smaller than the width of the slide 20 or the protective layer 21.

Further, the depth of the positioning ridge 30 and the positioning groove 31 is not greater than the minimum value of the thickness 1/10 of the carrier sheet 20 and the protective layer 21.

The color design layer 22 is composed of at least one ink layer, in this embodiment, three ink layers are provided, which are sequentially labeled as 220, 222 and 224 from bottom to top in fig. 1, the multiple ink layers can form a specific color distribution or pattern arrangement, the ink layers are coated on the surface of the protective layer 21 in a concave-convex pattern, and the height difference of the concave-convex pattern on a single layer is not greater than 1/10 of the average thickness of the ink layers.

A shielding layer 40 is arranged between the color design layer 22 and the adhesive layer 23, and the shielding layer 40 extends outwards and is fixed on the back surface of the carrier sheet 20, so as to shield and protect the color design layer 22, avoid influencing the whole transfer material and ensure the regularity of the edge.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
