ABSTRACT:
The invention relates to an aqueous binder composition having a long processing time (time within which the mixture can be processed without loss of quality) based on aqueous dispersions or solutions of binder mixtures, which contain at least one hydroxyl-group containing polyester dispersion or solution, at least one physically drying, aqueous polyurethane dispersion that is substantially free from hydroxyl or amino groups, and a polyisocyanate. The present invention also relates to the use of these binders in lacquers and coating compositions, in particular for coating rigid, non-flexible substrates.
