    摘要: An aqueous coating composition is described, containing, as binder, a mixture of (A) 50 to 95% by weight of a reaction product of a carboxy functional polycondensate containing epoxy groups, at least one copolymerisable o,-olefinically unsaturated monomer and conventional auxiliary agents, and (B) 50 to 5% by weight of a polyurethane dispersion, optionally together with a grinding resin. The process for the preparation of the aqueous coating compound and its use for the formation of coatings are also described.

    摘要: 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.

    摘要: 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.
