Metal Complex Dyes
Metal complex dyes are a type of premetallised dye that have a strong affinity towards protein fibers, such as wool and silk. Metal dyes are made up of one or two dye molecules that are coordinated with a metal ion. The dye molecule is typically a monoazo structure containing additional groups, such as hydroxyl, carboxyl or amino, that are capable of forming strong coordination complexes with transition metal ions, such as chromium, cobalt, nickel, and copper.
Metal-complex dyes can be found in various application classes of dyes, such as direct, acid, and reactive dyes. The pH conditions used in the dyeing process are regulated by the user class and the type of fiber being dyed (wool, polyamide, etc.). Metal complex dyes exhibit excellent wash fastness, light fastness, and heat stability.
These dyes are commonly used in the textile industry for dyeing wool, silk, and other protein fibers, as well as in the manufacture of printing inks and paints. The high affinity of metal-complex dyes towards protein fibers results in deeper and brighter shades, making them a popular choice for textiles, especially in the fashion industry. They are also used in the production of colour filters for electronic displays, photographic film, and various other applications where a high degree of colour purity is required.

Classification of Metal complex dyes
Metal complex dyes can be broadly classified into two types: metal complex acid dyes and metal complex solvent dyes.
Metal complex acid dyes are water-soluble dyes that are widely used for dyeing protein fibers such as wool and silk. They contain acidic groups such as sulfonic acid, carboxylic acid, or phenol, which allow them to form strong coordination complexes with metal ions. Metal complex acid dyes are generally applied in acidic conditions and exhibit excellent colorfastness properties.
Metal complex solvent dyes are organic-soluble dyes that are used for dyeing a range of materials, including plastics, coatings, and printing inks. They contain non-ionic or weakly acidic groups such as hydroxyl or amide, which allow them to form coordination complexes with metal ions. Metal complex solvent dyes are generally applied in organic solvents and exhibit excellent solubility and stability properties.
Both types of metal complex dyes offer unique advantages and properties, making them suitable for use in a range of applications. Metal complex acid dyes are ideal for dyeing protein fibers, while metal complex solvent dyes are used for a range of industrial applications that require excellent solubility and stability properties.
