Thermal Paper Developer ( TG-SH, TG-MD )
In general, the Leuco dyes fail in accurate color development when dissolved unless they are dissolved with one or more organic acids. Good examples of organic acids suitable for the thermal paper are phenols such as bisphenol A (BPA) and bisphenol S (BPS). Other suitable acidic substances are sulfonyl elements such as BTUM and Pergafast 201. Alternative salicylic acid zinc salts like zinc di-tert-butyl salicylic acid have also been used as developing agents. However, as the environmental regulations for chemical materials have become more severe, the demand for bisphenol organic acid, a toxic substance, has fallen.
Currently, Glolinx is working at the forefront of eco-friendly business by distributing non-phenolic developer-manufactured eco-friendly materials that reduce phenol, especially when used alongside existing thermal paper developer called TG-SH in cooperation with a Japanese eco-friendly manufacturer.
In addition, TG-MD is a new 100% eco-friendly and non-phenolic thermal paper developed so that it does not contain phenols, other than biphenols such as TG-SH, in order to remove the harmful elements of products that can directly affect consumers, such as POS thermal paper.
