Abstract: The present invention relates to aqueous binder dispersions for cationic electrocoat materials, comprising as binders amine-modified, hydroxy-functional epoxy resins and comprising as crosslinker at least one fully blocked polyisocyanate blocked at least partly with 2,2-dimethyl-1,3-dioxolane-4-methanol, and also to the use of such cationic electrocoat materials for producing coating systems and to the use of crosslinkers based on polyisocyanates blocked with 2,2-dimethyl-1,3-dioxolane-4-methanol in aqueous binder dispersions.
