Product Description of Pigment Yellow 139:

Pigment Yellow 139 is suitable for paint, plastic and printing ink. The different particle size distribution shows different color characteristics. The hue angle can be 78, 71, 66 degrees depending on the average particle size; the non-transparent type presents stronger red light ( Paliotol Yellow 1970 has a specific surface area of 22m2/g and L2140HD has a specific surface area of 25m2/g). Increasing the concentration does not affect gloss and has excellent light and weather fastness; it can be used with inorganic pigments to replace chrome yellow. It is suitable for high-end coatings (auto repair paint), with light resistance of 7-8 (1/3SD) in alkyd melamine resin; resistance to bleeding in soft PVC, and temperature resistance of 250 in HDPE (1/3SD) ℃, suitable for polypropylene.

Pigment yellow 139 is an organic compound that is used as a yellow-orange pigment. It is classified as a derivative of isoindoline. This yellow-orange solid is virtually insoluble in most solvents. The species is prepared by addition of ammonia to o-phthalonitrile to give the diiminoisoindoline, which in turn condenses with barbituric acid.
