6 ℃ Colorless to Red Screen Print Temperature Sensitive Ink

The color temperature of the discoloration pigment principle and structure: Thermochromic pigments are produced by electron transfer type organic compound systems. Electron transfer organic compounds are a class of organic chromophores with special chemical structures. The molecular structure of the organism changes due to electron transfer at a specific temperature, thereby achieving color conversion. This discoloring material is not only brightly colored but also capable of achieving a color change from a "colored to a colorless" state which is not possessed by the heavy metal double salt complex type and the liquid crystal type reversible thermochromic material.
