The invention relates to a process for producing water-dilutable varnish binders and their use in manufacturing water-dilutable fillers for automobile paintwork. The binders contain a reaction product, which is dilutable with water after the neutralisation of the carboxyl groups, of a polyurethane resin having carboxyl groups and at least one terminally blocked isocyanate group (polycarboxy component) with a polyester having a hydroxyl group (polyhydroxyl component) and a cross-linking component. Further improvements in the shelf-life of the varnishes can be attained by specially selecting the binder components and special processing steps for the combination thereof.
