Adhesive tape

[0031] First, see figure 1 and figure 2 as shown, figure 1 It is a three-dimensional schematic diagram of an adhesive tape in a roll state according to an embodiment of the present invention, figure 2 It is a schematic cross-sectional view of the adhesive tape of the embodiment of the present invention. An embodiment of the present invention provides an adhesive tape U, which includes an adhesive tape body 1 and a photochromic layer 2 . The photochromic layer 2 can be arranged inside the adhesive tape body 1 to produce the effect of changing color when exposed to light. Preferably, the tape U may further include a release layer 3 , the release layer 3 may be disposed on the tape body 1 , and the tape body 1 is disposed between the release layer 3 and the photochromic layer 2 . Thereby, through the setting of the release layer 3 , the adhesive tape U in the roll state can be easily separated from the upper layer of adhesive tape U during use. In addition, it is worth noting
