    摘要： The present invention relates to a process for the preparation of polyurethane resins, in which, in an ester as solvent, a) at least one compound having 2 hydroxyl and/or amino groups, b) at least one di- and/or polyisocyanate, c) at least one compound containing 2 groups which are reactive toward isocyanate groups, these compounds containing, at least in part, at least one group capable of forming anions which is neutralized before or after incorporation of component (c) into the polyurethane molecule, and d) at least one compound having at least 3 hydroxyl and/or amino groups are used to prepare a polyurethane resin, preferably using components (a), (b) and (c) to prepare an intermediate which has terminal isocyanate groups and at least some of whose free isocyanate groups are subsequently reacted with component (d), characterized in that ethoxyethyl propionate is employed as solvent.

    摘要： The present invention relates to a mixer system for the production of water-thinnable coating compositions having a precisely defined color shade, from various base colors, which mixer system is characterized in that it comprises A) various base colors A which contain less than 5% by weight of water, at least one color and/or effect pigment, organic solvent, at least one water-dilutable or water-dispersible acrylic polyurethane resin (A1) and/or polyacrylate resin (A2) and optionally auxiliaries and additives, and B) at least one pigment-free component B which contains water. The present invention also relates to a process for the production of coating compositions using this mixer system and to the use of the mixer system for the production of aqueous basecoats for the coating of automobile bodies and/or plastic parts, in particular for automotive refinishing.
