isoindoline orange
Isoindoline Orange 61 is an opaque, yellowish orange pigment with moderate tinting strength.
Isoindoline Orange 61 has very good lightfastness, although not as good as yellow pigments in the isoindoline group.
Isoindoline Orange 61 is not considered toxic.
The first isoindoline pigments were patented in 1946, and commercial production of pigments in this group began in the 1960s. Because of its high heat stability and relatively good lightfastness, PO61 is used in plastics, automotive finishes, and for printing inks. PO61 is often compared with PO13, which has higher tinting strength, but is not as lightfast.

C24H16Cl3N3O2
This Naphthol Red is an intense scarlet red pigment that is heavily staining. It has an average drying time. It is semi-transparent and has relatively poor covering power.
This Naphthol Red has been rated as having excellent lightfastness under ASTM testing, but other testing methods have demonstrated some tendancy for the color to fade with exposure to strong ultraviolet light. It has been considered a replacement for less lightfast naphthol reds such as PR3. Not suitable for exterior use.
Naphthol Reds are not considered toxic. Naphthol Red AS-D may cause eye, skin, or respiratory irritation. Contact with dry pigment should be avoided.
