Product Description of Pigment Yellow 12:

Pigment Yellow 12 is neutral yellow, in line with the color standard of four-color printing; high color strength, vividness and transparency (Lutetia yellow 2JRT specific surface area is 44m2/g); medium solvent resistance, showing a tendency to recrystallize; light and weather fastness Low, it is grade 3 and grade 2 at standard depths of 1/1 and 1/3, which is 1-2 grades lower than other yellow pigments (PY13,83,127,176). Widely used in printing inks, can be used for packaging printing inks, the United States uses squeeze to phase color paste formulations; can also be used for pigment printing and plastic coloring, soft PVC has a certain degree of migration, good heat resistance makes it used for polyurethane foam Plastic coloring.

Pigment yellow 12 is used for coloring of ink, paint, rubber, plastic, pigment printing paste, cultural and educational supplies.

Pigment Yellow 12 is an organic compound and an azo compound. It is a widely used yellow pigment. It is also classified as a diarylide pigment, being derived from 3,3'-dichlorobenzidine. It is closely related to Pigment Yellow 13, wherein the two phenyl groups are replaced by 2,4-xylyl.
