Product Information

• Name: Pigment yellow 139
• Brand: Biosynth
• Description: Pigment Yellow 139 is a colorant that is soluble in organic solvents and has a maximum absorption wavelength of 595 nm. It can be used as an optical system polarizer, and it is also used in liquid crystal compositions. Pigment Yellow 139 changes color depending on the pH of the environment, and it undergoes polymerization when irradiated with radiation or an acid complex. This pigment is also soluble in glycol esters and polycarboxylic acids. Pigment Yellow 139 is produced by reacting hydroxyl groups with polycarboxylic acid products. The pigments are then converted to particles by crystallizing them using a reaction product of particle emission.Pigment Yellow 139 has a crystalline structure composed of irregularly shaped particles that are about 0.2-0.4 micrometers in diameter.
