Description
[BASF] A registed trademark until 2010 for a series of synthetic dyes. Zapon dyes are initially soluble in water and most organic solvents. However, they hydrolyze in water or air to form a stable, insoluble product. They belong to the group of organic metal complex dyes , mostly with chromium or copper or cobalt as the central atom.
Zapon dyes are used as a component of transparent lacquers (such as Zapon lacquer) for metals and for wood stains. Some examples are:
