Abstract: Curable compounds, and the preparation and use thereof The invention relates to curable compounds carrying groups containing basic nitrogen, essentially comprising structural units derived from A) a compound which contains, on average, at least one, preferably terminal 2-oxo-1,3-dioxolane group per molecule, with B) a secondary diamine containing hydroxyl groups in the .beta.-positions to the secondary amino groups, it also being possible for this amine to contain blocked primary amino groups, and, if appropriate, C) a difunctional amine containing at least one free pri mary amino group and, if appropriate, at least one secondary amino group. The invention furthermore relates to a process for the preparation of the curable compounds and to their use, in particular in surface-coating preparations, specifically in electrocoating materials. The coatings obtained using these compounds are distinguished, above all, by optimized inter-layer adhesion.

Abstract: Curable compounds carrying basic nitrogen groups and essentially comprising structural units derived from A) a compound containing on average at least one terminal 2-oxo-1,3-dioxolane group per molecule, with B) a disecondary amine containing hydroxyl groups in the beta -position to the secondary amino groups, it also being possible for this amine to contain blocked primary amino groups, and optionally C) a bifunctional amine containing at least one free primary amino group and optionally at least one secondary amino group, are used, in particular, in surface coating preparations, especially in electrodeposition coating compositions. The coatings obtainable using these compositions have, in particular optimised interlayer adhesion.

Abstract: Aminourethanes, a process for their preparation and their use The invention relates to aminourethanes composed essentially of structural units derived from (A) polyamines of the general formula (I) an/or (II (I) (II) (B) if appropriate, further polyamines, (C) compounds containing, on average, at least one terminal 2-oxo-1,3-dioxolane group per molecule and (D) if appropriate, compounds having a monofunctional reaction, as chain stoppers. The invention also relates to a process for the preparation of these aminourethanes and to their use, in particular in paint formulations and especially in electrodeposition paints.
