Pigment yellow 83, transparency type and hemi-trans type, yellow HR02 P.Y.83 possesses excellent fastness properties, which make it almost universally applicable. It provides a reddish yellow hue, which is considerably more reddish than that of P.Y.13 and at the same time very strong. P.Y.83 is the standard pigment within the reddish yellow range. P.Y.83 shows good to very good resistance to most solvents which are typically found in application media. P.Y.83 shows excellent lightfastness, even in methylmethacrylate or unsaturated polyester cast resins. The pigment does not affect the hardening of the latter. P.Y.83 is also used to an appreciable extent in plastics. Because of its good solvent resistance, migration is no problem in plasticized PVC even at low pigment levels; it does not bleed or bloom.
