The Commonly Used Pigment Yellow 12 In The Printing Inks

Pigment Yellow 12 is an organic compound and an azo compound. It is widely used yellow pigment. It is also classified as diarylide pigment derived from 3,3’-dichlorobenzidine. It is closely related to Pigment Yellow 13, wherein the two phenyl groups are replaced by 2,4-xylyl. P.Y. 12 has a medium yellow hue, which is used to a large extent in letterpress and offset printing inks.

The fastness properties of P.Y.12 are somewhat lower than those of the substituted derivatives.

The transparency of P.Y.12 can be optimized to meet a variety of application requirements.

Pigment Yellow 12 types are used in packaging gravure and flexographic inks for their reasonable

price, but they can also be utilized in aqueous printing inks, provided they are sufficiently fast to light.
