Abstract: Carrier resin for pigment pastes, preparation and use thereof The invention relates to paste resins comprising (a) quaternary ammonium groups, (b) hydroxyl groups, (c) isocyanate radicals and (d) groups of the formula (I) (I) in which R1 to R4 independently of one another represent hydrogen or a hydrocarbon radical of 1 to 10 carbon atoms and X denotes hydroxyl or an isocyanate radical, the average molecular weight (Mn) of these paste resins being 500 to 10,000. The invention further relates to the preparation of these paste resins, their use for pigment pastes as well as these pigment pastes. Water-thinnable paints, especially electrocoating paints which comprise the pigment pastes according to the invention, furnish, from a variety of substrates, surfaces free from defects and comparable film thicknesses.

Abstract: A curing agent (A) for resins (B) which can be cured by means of isocyanates, which has an amine number of 20 to 150 mg of KOH/g and an OH number of not more than 20 mg of KOH/g and which contains per molecule at least two masked isocyanate groups which are reactive under the conditions of curing, obtained by reacting (a) an amine which contains at least one .beta.-hydroxyalkyl group per molecule and has an OH number of 100 to 1,200 mg of KOH/g and an amine number of 100 to 1,200 mg of KOH/g and which, if appropriate, also contains NHCO groups, if appropriate as a mixture with another OH-functional and/or NH-functional compound, with (b) a partly masked isocyanate, if appropriate as a mixture with an at least difunctional, OH-reactive and/or NH-reactive compound. These curing agents are readily dispersible in aqueous systems, if appropriate after neutralization, and frequently increase stability in aqueous paint formulations.

Abstract: Polyamines based on derivatives of 1,3-bissubstituted 2-propanol containing a multiplicity of amino groups, the latter containing at least one primary amino group and additionally further N-basic groupings, prepared by reacting 1,2,3-trisubstituted propane compounds with bis(primary amines or with monoamines and bis(primary amines). The polyamines according to the invention are clear to yellowish or yellow products which, at room temperature, form viscous to highly viscous liquids or may be paste-like or wax-like. They may be used, inter alia, advantageously as starting products for the preparation of thermosetting, in particular water-dispersible and cataphoretically depositable binders based on aminourethanes for coating solid substrates, in particular metals.
