Dianisidine Orange is a semi-opaque orange dye that can be laked to form a pigment. This pigment ranges from yellowish to reddish orange in different laked forms.
Dianisidine Orange has only fair lightfastness.
A Japanese study in which rats were given large daily doses of Dianisidine Orange revealed no acute toxicity or mutagenic effects.
Dianisidine Orange is used mostly in coloring plastics and in inks, in applications where safety is important but lightfastness and longevity are not paramount.

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.
