Introduction

Introduction

Pigment Red 31 is a synthetic monoazo pigment belonging to the β-naphthol pigment subclass. It produces a medium red shade, often described as slightly yellower and less bluish than Pigment Red 22. Valued primarily for its color strength and cost-effectiveness in printing inks, it offers moderate application properties. Its lightfastness and weather resistance are generally limited compared to high-performance pigments. Common historical uses include offset, packaging, and newspaper inks, as well as lower-grade paints and plastics where top durability is not required.
