Abstract
Catalysed, cationic compositions which contain one or more catalysed, cationic binders which can be diluted in water after being protonated and which contain one or more bismuth salts of hydroxycarboxylic acids are disclosed. The bismuth salts of lactic acid and dimethylolpropionic acid are particularly preferred, and the compositions are useful in cathodically precipitated paints.
