1. One is a color-changing mug consisting of an outer cup and an inner cup. A sandwich cavity filled with thermochromic volatile liquid is arranged between the bottom ends of the inner cup and the outer cup, and an artistic graphic channel communicated with the cavity is engraved on the outer side wall of the inner cup. When hot water is poured into the cup, the heat-sensitive liquid in the interlayer cavity will produce corresponding color and flow into the graphic channel of the inner cup, so that the cup wall presents artistic patterns, and users can get aesthetic feeling and artistic enjoyment when using the cup.
2. The other mug uses thermal transfer technology, which requires spraying a layer of transparent resin decal paper with certain special requirements on the surface of the mug. Generally, special thermal sublimation ink is printed on inkjet or special paper with a printer, and then heated at a certain pressure and temperature, and graphics and texts are coated on mugs by transfer printing. Because the color-changing mug uses temperature-sensitive color-changing ink, and the color-changing process is reversible, it is also called "reversible temperature colorless ink". When the temperature rises, the pattern of the bottom layer will be displayed.
