摘要
The invention relates to water-dilutable binders for cationic electrocoating finishes, the said binders containing latent primary amino groups. In order to prepare the binders, an epoxy resin is reacted with a polyamine, which in addition to a sterically hindered primary amino group also contains at least one primary amino group blocked by reaction with a ketone or aldehyde, and, if appropriate, further primary or secondary amines.
