Uses
Thermosensitive Color Development: Pergafast 201 serves as a thermosensitive color developer. In thermosensitive materials like thermal paper, it can interact with colorless dyes and other components in the thermosensitive coating. Upon exposure to a certain temperature, it chemically reacts with the colorless dye, causing a structural change in the dye and resulting in color development. This enables the recording and display of text, patterns, and other information. It is widely applied in thermosensitive printing scenarios, including fax machines, cash register systems, medical report printing, and logistics express delivery order printing.
Synthesis method
It is mainly synthesized from p-toluenesulfonyl isocyanate, m-aminophenol and p-toluenesulfonyl chloride as raw materials.
