Introduction

Pigment Red 53:1 (C.I. 15585:1; CAS 5160‑02‑1), also known as Lithol Rubine, is a warm, yellowish‑red monoazo lake pigment commonly used in inks, coatings, and plastics. It delivers vivid color with high tinting strength and good hiding power. The pigment exhibits excellent solvent and heat resistance (up to 180–200 °C), making it suitable for printing applications, including water-based flexo and offset inks. While its lightfastness is moderate, its cost-effectiveness and vibrant shade make it a popular choice for indoor and short-life product applications.
