Embodiment 1
[0041] A temperature-sensitive color-changing and heat-dissipating sticker is composed of a temperature-sensitive color-changing ink layer 1, a non-woven fabric layer 2, a hydrogel layer 3, and an embossed film layer 4. The temperature-sensitive color-changing ink layer 1 contains two kinds of inks, One is blue thermochromic ink, which changes from blue to colorless at 29°C; the other is orange thermochromic ink, which changes from orange to colorless at 31°C. The blue thermochromic ink and the orange thermochromic ink are printed on the upper surface of the non-woven fabric layer 2 by a flexographic printing process at intervals, and can be printed into various patterns, such as cartoon images that children like to make heat-relieving stickers It is more beautiful and popular with children. The hydrogel layer 3 is coated on the lower surface of the non-woven fabric layer 2, the embossed film 4 is attached to the other side of the hydrogel layer 3 opposite to the non-woven fabr...

[0061] A temperature-sensitive color-changing and heat-dissipating sticker is composed of a temperature-sensitive color-changing ink layer 1, a non-woven fabric layer 2, a hydrogel layer 3, and an embossed film layer 4. The temperature-sensitive color-changing ink layer 1 contains two kinds of inks, One is blue thermochromic ink, which changes from blue to colorless at 29°C, and the other is orange thermochromic ink, which changes from orange to colorless at 31°C. The blue thermochromic ink and the orange thermochromic ink are printed on the upper surface of the non-woven fabric layer 2 at intervals by a flexographic printing process. The hydrogel layer 3 is coated on the lower surface of the non-woven fabric layer 2, the embossed film 4 is attached to the other side of the hydrogel layer 3 opposite to the non-woven fabric layer, and the embossed film is a CPP film. When in use, only need to uncover the embossed film 4 and stick the hydrogel layer 3 directly on the forehead.
