Acid Metal Complex Dyes

Metal complex dyes are premetalised dyes that show great affinity towards protein fibres. In this dye one or two dye molecules are coordinated with a metal ion.
Metal-complex dyes belong to numerous application classes of dyes. For example, they are found among direct, acid, and reactive dyes. When applied in the dyeing processes, metal-complex dyes are used in pH conditions that is regulated by user class and the type of fibre type (wool, polyamide, etc).
