Abstract: The invention relates to a process for the production of a multicoat coating in which an aqueous transparent topcoat composition containing a polyacrylate resin as binder is employed. The polyacrylate resin can be obtained by adding, either successively or alternately in part amounts, a mixture of a carboxyl-containing ethylenically unsaturated monomer (a1) and a monomer (a2) free from carboxyl groups and a mixture (b) consisting of (meth)acrylic acid esters which are free from carboxyl groups, of hydroxyl-containing ethylenically unsaturated monomers and, if appropriate, of other ethylenically unsaturated monomers to an organic solvent and carrying out a polymerization in the presence of a radical-forming initiator and, at the end of the polymerization, neutralizing the resultant polyacrylate resin and dispersing it in water. The type and amount of (a1), (a2) and (b) are chosen so that the polyacrylate resin has a hydroxyl value of 40 to 200, an acid value of 20 to 100 and a glass transition temperature (T.sub.G) of -40.degree. C. to +60.degree. C.

Abstract: The invention relates to a process for the preparation of aqueous dispersions to be further processed to electrocoating paints with baking temperatures below 160° C. and baking times of ≦30 minutes, which dispersions contain modified epoxide-amine adducts as binders and polyisocyanates blocked by amino groups as crosslinking agents. In this process, polyepoxides and compounds which contain one or more, preferably 2, hydroxyl groups per molecule are converted at higher temperatures and in the presence of catalysts to epoxide-containing intermediates. A solvent or a mixture of solvents is then added with external cooling and the solution is then caused to boil under reflux, if necessary by application of a vacuum, until the temperature of the solution drops to 95° C. to 20° C. Amines are then added onto the epoxide groups which are still present in a free state in the epoxide resin and either a dispersion is prepared after the addition of the crosslinking agent by adding a water-acid mixture or the products are first dispersed and the crosslinking agent is added subsequently.

Abstract: The invention relates to a process for the preparation of polyester and alkyd resins from bifunctional and/or polyfunctional carboxylic acids and/or derivatives thereof and from bifunctional and/or polyfunctional alcohols. The reaction is carried out in stirred kettle reactors which are operated discontinuously and equipped with rectifying columns. During the entire reaction an entraining agent is introduced into the reaction mixture below surface level, with thorough distribution, by means of a delivery device in order to improve the transport of the products of the condensation reaction. In addition, the condensation reaction is carried out under an absolute pressure of 1.5 to 10 bar at least until the maximum reaction rate has been reached. The pressure is then reduced to atmospheric pressue at a gradient of -0.05 bar/hour to -5 bar/hour in a second reaction phase. The reaction is continued under normal pressure until the product exhibits the desired properties. The reaction temperature is between 180 and 320.degree. C.The process times, in particular, are shortened as a result of this process, and the process products, which are exposed to heat for a correspondingly shorter time, are distinguished by imprved properties.
