Abstract
The invention pertains to a method for producing preparations containing bismuth salts, wherein bismuth oxide is reacted in a specific way with lactic acid and the resulting mixture of bismuthyl lactate and bismuth lactate is dispersed in a binder. These preparations are used as catalytic components in electrophoretic paints to be applied by cathodic deposition. Dipping paints of this kind have excellent application and film properties. This obviates the need to use lead and tin compounds as catalysts.
