HP YELLOW 1679 / PIGMENT YELLOW 65

Pigment Yellow 65

Pigment Yellow 65 provides reddish yellow shades. The types which are still commercially available consist of pigments with comparatively coarse particle sizes and with specific surface areas of approximately 6 to 20 m2/g.

 The pigment thus provides excellent hiding power. There is some resemblance between Pigment Yellow 65 and P.Y.74 types with high hiding power in that they perform equally well in terms of solvent resistance, recrystallization fastness in solvent containing media, lightfastness, and durability. P.Y.65 is considerably inferior, which precludes its application in printing inks. Opaque varieties of the slightly more greenish diarylide yellow pigment P.Y.83, for instance, are more than three times as strong as P.Y.65, yet provide similar lightfastness. Media in which P.Y.65 grades are applied include air drying and emulsion paints.
