Further, as shown in fig. 2 and 3, an ink-absorbing layer 9 and a transparent PU layer 10 may be further disposed between the intermediate crosslinking layer 5 and the pattern layer 6.
The substrate layer 1 is a carrier layer and has the characteristics of good temperature resistance, pressure resistance and small tensile deformation. In this embodiment, the base material layer 1 is a PET film.
The three-dimensional reverse grain layer 2 is compounded on the substrate layer 1 and is provided with reverse three-dimensional grains 21. The reverse three-dimensional texture 21 is a reverse texture of a three-dimensional texture which needs to be presented finally. Similarly, the positive three-dimensional texture 41 is a three-dimensional texture that needs to be presented finally. The reverse three-dimensional texture 21 may be a dot texture, such as a dot structure, or a linear texture, such as a grating structure continuously arranged in the width direction. The texture structure of the reverse three-dimensional texture 21 is not limited in this embodiment, and may be specifically set as required.
The three-dimensional reverse-grain layer 2 may be formed by UV curing. During specific implementation, the substrate layer 1 is coated with UV glue, then a die with the positive three-dimensional grains 41 is used for rolling, and after UV light curing, the three-dimensional reverse grain layer 2 with the reverse three-dimensional grains 21 can be formed on the substrate layer 1.
The release agent layer 3 is arranged between the three-dimensional positive grain layer 2 and the three-dimensional positive grain layer 4 and is used for isolating the three-dimensional positive grain layer 4 from the three-dimensional positive grain layer 2, so that the three-dimensional positive grain layer 2 is peeled off from the three-dimensional positive grain layer 4 during thermal transfer printing. In specific implementation, a release agent is coated on the three-dimensional reverse texture layer 2, so that the release agent layer 3 can be formed.
The three-dimensional positive texture layer 4 is provided with positive three-dimensional textures 41. The positive direction three-dimensional grains 41 and the negative direction three-dimensional grains 21 are of an inlaid structure. For example, when the reverse three-dimensional texture 21 is a concave structure, the forward three-dimensional texture 41 is a convex structure with a shape matching with the concave structure. The positive three-dimensional texture 41 is a texture which needs to be retained after thermal transfer printing, namely a three-dimensional texture which is finally required. The positive direction three-dimensional grain 41 is set according to the reverse direction three-dimensional grain 21, which can be specifically set according to the requirement. In specific implementation, a fluid material is filled between the reverse three-dimensional grains 21 of the three-dimensional reverse grain layer 2, i.e. the reverse three-dimensional grains 21 are filled and leveled, and then the three-dimensional positive grain layer 4 with the forward three-dimensional grains 41 can be formed after solidification.

In specific implementation, a cross-linking agent is coated on the side of the three-dimensional positive texture layer 4 opposite to the positive three-dimensional texture 41, so that the intermediate cross-linked layer 5 can be formed.
In some embodiments, the intermediate crosslinking layer 5 may be formed by coating with a plasma surface treatment agent. In some embodiments, the intermediate crosslinking layer 5 may be formed by coating with a silica gel crosslinking agent.
Furthermore, in some embodiments, as shown in fig. 3, in order to improve adhesion between the composite layers, a transparent PU material may be further coated on the intermediate crosslinking layer 5 to form a transparent PU layer 10.
When the stereoscopic positive texture layer 4 is a silica gel layer, the transparent PU layer 10 is preferably disposed on the intermediate cross-linked layer 5. When the cubic positive texture layer 4 is a TPU layer, the transparent PU layer 10 may not be provided on the intermediate crosslinked layer 5.

The ink absorbing layer 9 can be made of a material having an adsorption capacity to ink or a material having a certain water absorption capacity. In specific implementation, the ink-absorbing layer 9 can be formed by coating the material for the ink-absorbing layer 9 on the intermediate crosslinking layer 5 or the transparent PU layer 10. The ink-receptive layer 9 is a transparent layer. When the transparent PU layer 10 is not provided, the ink-receiving layer 9 is formed by coating on the intermediate crosslinked layer 5. When the transparent PU layer 10 is provided on the intermediate crosslinked layer 5, the ink-receiving layer 9 is formed by coating on the transparent PU layer 10.
The pattern layer 6 is provided with a pattern, which is usually patterned by printing. For example, the desired pattern is printed by silk-screen printing, offset printing, ink-jet printing, digital printing, and the like. The pattern on the pattern layer 6 is a plane pattern, which is matched with the positive three-dimensional grain 41 on the three-dimensional positive grain layer 4. The combination of the plane pattern and the three-dimensional grain can generate the three-dimensional change effect with strong real effect.
The base color layer 7 is a coating carrier of an adhesive and is used as a substrate of the pattern layer 6. The base colour layer 7 generally has a certain elasticity. In this embodiment, the bottom color layer 7 is a white PU layer. In specific implementation, the base color layer 7 can be formed by coating a white PU material on the pattern layer 6.
The adhesive layer 8 is used for adhering the transfer printing film to the surface of the printing stock during heat transfer printing, so that the heat transfer printing film is firmly combined with the surface of the printing stock. In this embodiment, the adhesive used for the adhesive layer 8 is a hot melt adhesive, and thus is a hot melt adhesive layer. The hot melt adhesive layer can enable the transfer printing film to have better adhesive property and physical property, so that the transfer printing film can not be stretched and exploded during transfer printing, and simultaneously, various properties such as temperature resistance, water resistance and cold and heat shock resistance can be improved. In specific implementation, the adhesive layer 8 can be formed by coating hot melt adhesive on the base color layer 7.
Further, in order to facilitate production and improve product performance, a matte release agent can be coated on one side of the substrate layer 1, which is far away from the three-dimensional reverse-grain layer 2.
