摘要： A cathodically precipitable aqueous electro-dipcoating agent which includes as Component A, 50 to 99% by mass (relative to the total quantity of Components A and B) of a synthetic resin binder having tertiary amino groups and hydroxyl groups which can be rendered water soluble by protonation with acids, and which(a) has an amine number of 35 to 120,(b) has a hydroxyl number of 50 to 400,(c) has substantially no primary, secondary and quaternary amino groups,(d) has substantially no free isocyanate groups, and(e) has substantially no blocked isocyanate groups which can react at baking temperatures of up to 200.degree. C. with hydroxyl groups present in the reaction components.The agent also includes as Component B, 1 to 50% by mass (relative to the total quantity of Components A and B) of substantially non-acid synthetic resins having at least two terminal esterified carboxyl groups which can react under normal lacquer baking conditions with Component A, accompanied by cross-linkage.

摘要： Process for the production of multi-layer lacquer coatings by electrophoretic deposition of a first coating layer of a first, aqueous coating composition onto an electrically conductive substrate, application of a second coating layer based on a second, powder coating composition and joint baking of the coating layers so obtained, which process is characterised in that a powder coating composition is used for the second coating layer which is based on binders which contain no diene-based polymer units, wherein the coating composition is selected such that the minimum baking temperature range of the second coating layer is above that of the first coating layer or overlaps with this range in such a manner that the lower limit of the range of the second coating layer is above the lower limit of the range of the first coating layer.
摘要翻译：用于通过将第一水性涂料组合物的第一涂层电泳沉积到导电基材上来生产多层漆涂层的方法，施加基于第二粉末涂料组合物的第二涂层和该方法的特征在于，粉末涂料组合物用于基于不含二烯基聚合物单元的粘合剂的第二涂层，其中选择涂料组合物使得最低烘烤温度范围为所述第二涂层高于所述第一涂层的厚度，或者以所述第二涂层的范围的下限高于所述第一涂层的范围的下限的方式与所述范围重叠。
