PO16-Dianisidine Orange
organic, disazo
C34H32N6O6
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.
PR48:3-Permanent Red
organic, monoazo
beta-oxynaphthoic acid lake, strontium salt
Permanent Red is a common name used for the strontium salt of beta-oxynaphthoic acid (BONA) lake pigment PR:48. It is substantially bluer than other shades of PR:48. BONA pigment lakes tend to have high tinting strength, however the tinting strength of PR48:3 is only average.
Beta-oxynaphthoic acid (BONA) lake pigments are more lightfast than their beta-naphthol counterparts. Although their lightfastness makes them the pigment of choice in many applications, they may shift slightly in color or lose intensity under some conditions. Pigment PR48:3 has been reported to be the most lightfast of the BONA lake pigments.
Pigment Red PR48:3 is a lake pigment of beta-oxynaphtholic acid, a dye that resembles the common beta-Naphthol pigments. Beta-oxynaphthoic acid may have been synthesized as early as 1887. Commerical use of BONA lake pigments began in the 20th century. PR48:3 is used in printing, plastics, architectural paints, and industrial finishes.
