Pigment Yellow 120

CAS: 29920-31-8

Pigment Yellow 120 is a pigment that belongs to the group of amide colorants. It has a yellow-orange hue and high thermal stability. Pigment Yellow 120 has been shown to be soluble in organic solvents, such as n-propyl ether, but insoluble in water. The molecular weight of pigment yellow 120 ranges from 800 to 1200 g/mol. Pigment Yellow 120 is produced by the polymerization reaction of monomers containing an amide group and a hydroxyl or basic group with a metal ion, such as copper or nickel, as a catalyst. This process also produces polycarboxylic acid groups and particles with diameters ranging from 0.1 micrometers to 2 micrometers.
