HP YELLOW 15157 / PIGMENT YELLOW 139

Pigment Yellow 139
P.Y.139 is a reddish yellow pigment, used in plastics, paints, and printing inks. The
commercial types exhibit a wide variety of particle size distributions and accordingly
demonstrate very different coloristic properties, which is especially true for
the hiding power. The opaque version is considerably redder. Incorporated in a
paint, it is less viscous, which makes it possible to increase the pigment concentration
without affecting the gloss of the product. The printing ink industry utilizes P.Y.139 to color high grade printing products.
