The present invention relates to aqueous dispersions of polyurethanes containing hydantoin groups (calculated as C.sub.3 N.sub.2 O.sub.2, MW 96) in an amount of 1 to 40% by weight, based on resin solids. The present invention also relates to the use of these dispersions for preparing coatings with excellent hydrolytic and thermal stability.

The present invention relates to process for preparing a coated substrate having improved resistance to yellowing which comprises coating a substrate with a one-component coating composition containing a) a blocked polyisocyanate which is the reaction product of a polyisocyanate with an oxime or lactam blocking agent for isocyanate groups and b) a compound containing at least two isocyanate-reactive groups, provided that component a) and/or component b) contains the group, --CO--(R)N--N(R)--CO--, wherein R represents hydrogen or an optionally substituted hydrocarbon radical, in an amount of 0.01 to 5% by weight, based on the solids content of components a) and b), by applying the one-component coating composition wet-on-wet to a coating composition containing acid groups and/or melamine resins which has previously been applied to the substrate or by adding a melamine resin to the one-component coating composition prior to applying it to the substrate, which may optionally have been precoated. The present invention also relates to the coated substrate having improved resistance to yellowing prepared by this process.

A high solids, chip resistant, sprayable polyurethane coating composition comprising the reaction mixture of a ketoxime-blocked polyisocyanate and a cyclohexanedicarboxylic acid-based polyester polyol, is disclosed. The composition is characterized by its relatively low viscosity and the resulting coating is characterized by its low volatile organic content.
