本发明涉及一种用于制备阳离子粘合剂的颜料糊的水可稀释的涂料，特别是用于低分子量的基础上阴极电沉积（CED）使用，携带改性环氧化合物的恶唑烷的基团。 该方法的特征在于，一个反应与伯单 - 和/或二胺，和任选，单羧基化合物优选为脂族二 - 或聚环氧化合物，和通过与在所述分子的恶唑烷羰基化合物进一步反应将。 该产品具有极高的可着色性和优异的性能。 在阴极电沉积的涂层材料一起使用时它们能生产低溶剂涂料体系。

The invention relates to a process for the preparation of cationic binders for pigment pastes for water-dilutable paints, in particular for use in cathodic electrodeposition (CED) on the basis of low molecular weight, modified epoxide compounds carrying oxazolidine groups. The method is characterized in that preferably aliphatic di- or polyepoxide compounds with primary mono- and / or diamines as well as optionally responding monocarboxyl compounds, and incorporates by further reaction with carbonyl compounds in the molecule oxazolidine. The products exhibit exceptionally high Pigmentability and excellent properties when used in cathodic electrodeposition coatings. They allow the preparation of low-solvent coating systems.
