Color developer Bisphenol S

As a heat-sensitive recording material and color photographic color-developing material, BPS has the characteristics of high sensitivity, good stability, high image definition, water resistance, oil resistance, light resistance, heat resistance and plasticizer resistance. Fields (such as thermal recording paper, electrocardiogram, fax paper, etc.) have been widely used.

As a substitute for bisphenol A, it is mainly used for high-sensitivity thermal recording paper (such as fax paper), color photosensitive materials and liquid crystal materials, and special engineering plastic monomers such as polyethersulfone and polyimide.

In addition, BPS can also be used as an intermediate for the synthesis of pesticides, dyes, polyesters, epoxy resins, etc., and can also be used as a plating solution additive, leather tanning agent, dye dyeing dispersing agent, color fixing agent, etc.
