Prodn. of a (I) by heating an at least bifunctional 2-oxo-1,3-dioxolan (II) and a prim polyamine at 20-150 deg.C is claimed. Structural formulae are given for pref. R, viz. residues of a bisphenol diglycidyl ether opt. linked by residues of a diamine, diol, dicarboxylic acid, di-isocyanate, etc. Pref. (II) is bicyclic carbonate of specified formuls esp. derived from polyglycidyl ether of a polyphenol, or a epoxide-cyclic carbonate.

    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: The invention relates to paste resins containing (a) quaternary ammonium groups, (b) OH groups, (c) isocyanate radicals and (d) groups of the formula (I) in which R to R , independently of one another are hydrogen or a hydrocarbon radical having 1 to 10 carbon atoms, and X is hydroxyl or an isocyanate radical, the mean molecular weight (Mn) of these paste resins being from 500 to 10000. The invention furthermore relates to the preparation of these paste resins, to their use for pigment pastes and to these pigment pastes. water-thinable surface coatings, in particular electrodeposition coatings, which contain the pigment pastes according to the invention give defect-free surfaces and comparable coating thicknesses, even on different substrates.

    Abstract: 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.
