Abstract: Process for producing a multilayer lacquer coating, in which a primer of an electrophoretically depositable aqueous coating agent (1) is electrophoretically applied on to an electrically conductive substrate and is then stoved, whereupon a color-giving and/or effect-producing base lacquer coat of an aqueous coating agent (II) is applied and stoved and this coat is then provided with one or more clear lacquer coatings, in which processa) as the coating agent (I), a coating agent which, in the stoved state, will produce an electrically conductive primary coat is used,b) the base lacquer coat is formed by an electrophoretically depositable aqueous coating agent (II) by a process of electrophoretical deposition,c) the overall dry layer thickness of the dry lacquer coat or dry lacquer coats is about 40 and 80 .mu.m, andd) the overall dry layer thickness of the multilayer lacquer coating is about 80 to 110 .mu.m.

Abstract: In a process for producing a multilayer lacquer coating, eg for motor vehicles, a first coating layer of an aqueous coating agent (1) is electrophoretically applied on to an electrically conductive substrate and is then stoved. As the coating agent (I), a coating agent which, in the stoved state, will produce an electrically conductive coating layer is used. An electrically insulating second coating layer of an aqueous coating agent (II), which differs from (I), is electrophoretically deposited and stoved. A third basic lacquer coating layer of a colour-giving and/or effect-producing coating agent is applied, and a fourth transparent coating layer of a clear lacquer coating agent is applied, the last-mentioned two coats being stoved together. One or more further transparent coating layers may be applied.

Abstract: A process for the effect coating of polar plastics parts having a grained surface, characterised in thata) a first coating layer, which is free from effect pigments and modified polyolefines and which comprises a coating medium based on physically drying binder vehicle systems which contain one or more polyurethane resins and/or oligomeric urethanes and which do not chemically crosslink at the temperatures employed in process step f), is applied at a dry coat thickness of 5 to 40 .mu.m,b) is dried at 20.degree. to 80.degree. C. down to a residual content of 3 to 20% by weight of the volatile fractions which are contained in the applied coating film at the temperature employed,c) is overcoated wet-into-wet with an effect base lacquer,d) is dried at 20.degree. to 80.degree. C.

Abstract: Vehicles, which are water dilutable after neutralization with bases, have an acid number of 5 to 60 and are obtainable by polymerization or copolymerization of 10 to 90 parts by weight of one or several acidic, phosphoric acid-functional unsaturated monomers, which are polymerizable by a free radical mechanism and can be present in admixture with one or several ethylenically unsaturated monomers, which are also polymerizable by a free radical mechanism, with addition of a free radical initiator, in the presence of 90 to 10 parts by weight of one or several epoxide resins or modified epoxide resins, in one or several solvents. Methods of synthesizing them, aqueous coating materials containing them and their use.
