General Description

C.I. Acid Brown 45 is a synthetic, complex dye known for its colorfast properties in textile production. It is a type of acid dye, typically soluble in water and applicable to fibers such as wool, silk, and nylon. Despite its name, it does not contain any acidic or harmful components, but rather requires an acidic environment for ideal coloring purposes – the “acid” in its name refers to this requirement, not its composition. Its exact chemical composition is not universally established due to the variants available in the market, but it is known to be large organic molecules that are produced from the raw materials from the coal tar industry. The dye is appreciated for high light fastness and wet fastness, as well as notable shade continuity.
