The invention relates to a process for coating vehicle bodies in which an aqueous coating containing as the binder a combination of a water-dilutable polyurethane resin, a water-dilutable polyester resin and an aminoplast resin is employed as the stone-chip intermediate primer and/or filler.

Process for coating vehicle bodies and aqueous coating

A coating composition comprises an alkyd resin based topcoat and a water dilutable coating comprising an epoxy resin-modified polyester binder which is water-dilutable upon base neutralization of the free carboxyl groups and is prepared by the reaction of (A) a polyester containing (cyclo)aliphatic groups having at least six carbon atoms derived from (a.sub.1) a polycarboxylic acid with at least three carboxyl groups and/or (a.sub.2) a polyol with at least one carboxyl group, (a.sub.3) a polycarboxylic acid with two carboxyl groups and (a.sub.4) a polyol; and (B) a bisphenol epoxide resin.

Epoxide resin-modified polyester coat with alkyd topcoat

A substrate is spray coated with a composition containing an epoxy resin-modified polyester binder which is water-dilutable upon base neutralization of the free carboxyl groups and is prepared via the reaction of A) a polyester containing (cyclo)aliphatic groups having at least six carbon atoms derived from (a.sub.1) a polycarboxylic acid with at least three carboxyl groups and/or (a.sub.2) a polyol with at least one carboxyl group, and (a.sub.3) a polycarboxylic acid with two carboxyl groups and (a.sub.4) a polyol; and (B) a bisphenol epoxy resin.

Spray coating with carboxyl polyol-derived polyester and epoxy resin

A water-dilutable coating comprising a binder obtained from an epoxide resin-modified polyester possessing free carboxyl groups prepared from the reaction of:

Carboxyl polyol-derived polyester and epoxide resin aqueous coating

Water-thinnable baking paints and use thereof as filler material and

Epoxide resin-modified polyesters derived from carboxyl polyol
