Premetallized acid:- Explained in brief
by : Rahul Sharma
Premetallized acid:-
Premetallized acid dyes fall into two classes
1 metal-complexes, in which one dye molecule is complexed with one metal atom and the more modern,
2 metal complexes, in which one metal atom is complexed with two dye molecules. The dye molecule is typically a monoazo structure containing additional groups such as hydroxyl, carboxyl or amino groups, which are capable of forming strong co-ordination complexes with transition metal ions, typically chromium, or cobalt.
