1,2-Diphenoxyethane plays a crucial role in thermal paper. Its primary function is as a sensitizer or solvent, making it a key additive in thermal coating formulations.

When the heating element of the thermal printhead comes into contact with the paper, the heat melts the coating, and the colorless dye and developer react instantly, creating an imprint (usually black or blue) at the corresponding location. In this system, zinc stearate emulsion plays a crucial role as a "physical optimizer." It does not participate in the color-developing chemical reaction itself, but its physical properties greatly improve the coating's performance and print quality. Its main

Hollow spheres play a crucial role in thermal paper, serving as a key functional filler.The primary function of hollow spheres in thermal paper is as a "miniature heat insulation layer" and a "color development optimization layer." Through their unique physical structure, they precisely control heat transfer, thereby improving print quality and paper performance. Their specific functions are as follows:
