PR49:1-Beta Naphthol Red
organic, monoazo
barium monoazo red lake

Pigments in the beta naphthol group are considered moderately lightfast. The naphthol AS pigments, which are more permanent, have largely taken their place in artist paints.
The Beta Naphthol colors were developed in the late 19th century. PR49 has been used in paints, plastics, printing inks, and cosmetics. Most of the PR49:1 pigment manufactured in the United States is used for printing and packaging applications.

monoazo
C18H18N4O6
This Hansa Yellow ranges from reddish yellow to greenish yellow with temperature shifts from cool to warm hues. It has good tinting strength and average to slow drying time.
