Introduction

Solvent Red 52 is a high-performance solvent dye suitable for resin coloration. It remains insoluble in water, yet shows strong solubility in concentrated acids — yielding a deep red solution in concentrated sulfuric acid which produces a red precipitate upon dilution. This behavior reflects its robust chemical structure, making it effective for stable coloring of resin-based materials.
