Description of TGSH Color developer
2,2'-Diallyl-4,4'-sulfonyldiphenol, commonly known as TGSH, is a specialized organic compound recognized for its critical function as a high-efficiency color developer in thermosensitive imaging systems. With the CAS number 41481-66-7 and the molecular formula C₁₈H₁₈O₄S, it appears as an off-white to white crystalline powder . Chemically, it is also known as Bis(3-allyl-4-hydroxyphenyl) sulfone or 3,3'-Diallyl-4,4'-dihydroxydiphenylsulfone, characterized by a diphenyl sulfone core with allyl substituents . Its molecular weight is 330.40 g/mol
Advantages of TGSH Color developer
One of the defining characteristics of TGSH is its excellent thermal reactivity and stability. It possesses a well-defined melting point, typically reported between 138.5°C and 151.5°C, which is crucial for its function in heat-activated applications . High-purity grades (≥97.5% to 99%) are commonly available, ensuring consistent and reliable performance . Its structure allows it to act not only as an efficient proton donor to react with leuco dyes but also as a sensitizer, effectively lowering the activation temperature required for the color-forming reaction and enabling faster, more energy-efficient printing
Application of TGSH Color developer
The primary and most significant application of TGSH is as a color developer in the production of thermal paper . It is a key component in the heat-sensitive coating that produces images on facsimile paper, point-of-sale receipts, and various types of printing and labeling papers . When heat is applied by a thermal print head, the TGSH melts and interacts with a colorless leuco dye, triggering an instantaneous chemical reaction that results in a sharp, durable image. Its use helps ensure the legibility and longevity of prints, as it offers resistance to environmental factors like moisture and oils . Beyond direct use in paper, TGSH is also utilized in the preparation of microcapsules for advanced light-thermal sensitive imaging systems, demonstrating its versatility in imaging technology
