[0006] In a preferred embodiment of the utility model, the thermal sublimation dye adsorbed cellulose edging is exposed on the side of the cured double-layer photosensitive resin, and the adjacent cured double-layer photosensitive resin and the dye moisture absorption layer are semi-enclosed to form a dye droplet absorption space, and the width of the dye droplet absorption space does not exceed 100μm.

Obviously, the drawings described below are only some embodiments of the present utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative work, among which:
[0009] Figure 1 It is a structural diagram of a preferred embodiment of the utility model of a high-absorption thermal sublimation transfer paper. DETAILED DESCRIPTION
[0010] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0011] like Figure 1 As shown, the embodiment of the utility model includes:
[0012] A high-absorption thermal sublimation transfer paper comprises a base paper 1, a thermal sublimation dye adsorbing cellulose layer 2, a dye moisture absorbing layer 3, a cured double-layer photosensitive resin 4, and a thermal sublimation dye adsorbing cellulose edging 5. The base paper 1 is provided with the thermal sublimation dye adsorbing cellulose layer 2, the thermal sublimation dye adsorbing cellulose layer 2 is coated with the dye moisture absorbing layer 3, the dye moisture absorbing layer 3 is printed with a cured double-layer photosensitive resin 4, and the thermal sublimation dye adsorbing cellulose edging 5 is half-embedded between the cured double-layer photosensitive resin 4.
[0013] The double-layer photosensitive resin 4 after curing is in the shape of a straight line and is arranged in parallel with equal intervals.
[0014] Furthermore, the thermal sublimation dye adsorbed cellulose edging 5 is exposed on the side of the cured double-layer photosensitive resin 4, and the adjacent cured double-layer photosensitive resin 4 and the dye moisture absorbing layer 3 are semi-enclosed to form a dye droplet absorption space, and the width of the dye droplet absorption space does not exceed 100 μm.
[0015] This product is realized by 3D printing technology. A layer of photosensitive resin is first laid on the finished thermal sublimation paper. The photosensitive resin is printed on the paper surface in the form of silk threads and solidified to form a base layer. Then a layer of thermal sublimation dye-absorbed cellulose edging 5 is laid. The thermal sublimation dye-absorbed cellulose edging 5 is accumulated on the first layer of solidified photosensitive resin and formed after drying. Finally, it is sent to the 3D printer to print the second layer of photosensitive resin. The thermal sublimation dye-absorbed cellulose edging 5 is semi-enclosed and packaged, so that a large amount of dye droplet absorption space is obtained.
[0016] During post-production, the thermal sublimation dye ink droplets will be over-sprayed in the dye droplet absorption space. The ink droplets will be absorbed by the thermal sublimation dye adsorbing cellulose layer 2 and will also be stored in the thermal sublimation dye adsorbing cellulose edging 5 .
[0017] In this way, when performing thermal sublimation transfer, the amount of ink transferred can be more accurately controlled by precisely controlling the transfer temperature, thereby significantly enhancing the contrast of the transferred pattern.
[0018] In summary, the utility model provides a high-absorption thermal sublimation transfer paper, which adds a double layer of photosensitive resin on the paper surface to construct a dye droplet absorption space, and expands the ink droplet absorption amount by 3D embedding the thermal sublimation dye adsorbing cellulose border 5, thereby improving the paper's absorption performance for the dye and improving the picture quality of the thermal sublimation image.
[0019] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
