摘要： HOE 86/F 318 of the disclosure 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) and/or (II) ( I ) (II) (?) if appropriate, further polyamines, (C) compounds containing, on average, at least one ter minal 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.

摘要： A process for the preparation of aqueous epoxy resin dispersions comprising (1) 20 to 75% by weight, based on the total dispersion, of an epoxy resin constituting a condensation product of a) epoxy compounds having at least one epoxy group per molecule and an epoxide equivalent weight of 90 to 3000 g/mol, and b) aromatic polyols; (2) 3 to 20% by weight, based on the total dispersion, of an emulsifier comprising a) a condensation product of an aliphatic polyol and an epoxy compound having at least two epoxy groups per molecule and an epoxide equivalent weight of 90 to 3000 g/mol, the equivalent ratio of the OH groups to the epoxy groups being 1:0.85 to 1:1.5 and the epoxide equivalent weight of this condensation product being between 5000 and 400,000 g/mol, b) an organic solvent, and c) water; (3) up to 10% by weight, based on the total dispersion, of organic solvents; and (4) water in an amount to make up to 100% by weight, which comprises stirring the epoxy resin (1) firstly with the emulsifier (2) and, if appropriate, organic solvents corresponding to (3), and then with water.
