Basic Orange 2, widely known as Chrysoidine, is a classic azo dye that produces a strong, reddish-orange shade. This liquid version provides a convenient, ready-to-use solution for a variety of industrial colouring applications. It is particularly effective for dyeing substrates with an anionic character, such as leather, paper, and wood. Its strong colour and cost-effectiveness make it a versatile workhorse for achieving deep orange and brown shades.
