It is common practice to dye at temperatures below the boil, preferably below 90°C, and to limit the time of dyeing at high temperatures, so as to curtail any adverse effects on lustre and other desirable properties. In 1:1 complexes, three coordination sites are occupied by trivalent metal, whereas the remaining three coordination sites are occupied by solvents, like water. 6.

Metal-complex dyes have low water solubility; the solubility decreases from 1:1 metal-complex type to 1:2 complex type (see Section 13.6); most are of monoazo type and are derived through complexion of selective metals with acid dyes possessing o-o′ chelating sites such as –OH, –COOH, –NH2, etc. For instance, bivalent Cu2+ ion, possessing coordination number four, can be complexed with two bidentate ligands in an acid dye or a trivalent or a tetravalent one.
