Introduction

Introduction for Solvent Violet 31:

Solvent Violet 31 is an anthraquinone-based solvent dye that yields a strong bluish‑violet shade with high tinting strength and excellent transparency. It dissolves readily in non‑polar organic solvents and a wide range of polymers—including PS, ABS, PET, PC, PVC plastisols, and polyolefins—making it popular for coloring plastics, synthetic fibers, waxes, and printing or flexographic inks. The dye exhibits good heat stability (typically up to 260 °C in polyesters), respectable lightfastness for indoor or short‑term outdoor use, and low migration in most non‑polar systems. Because of these attributes, Solvent Violet 31 is frequently chosen for applications requiring vivid, durable violet tones.
