    摘要： The present invention relates to aqueous polyurethane dispersions prepared from a polyisocyanate component and one or more isocyanate-reactive compounds wherein at least 5% by weight of polyisocyanate component is a diisocyanate corresponding to formula (I) wherein R is a difunctional, C4 to C18, aliphatic, cycloaliphatic or aromatic hydrocarbon residue obtained by removing the NCO groups from an organic diisocyanate and R′ is a monofunctional, C1 to C18 hydrocarbon radical, which may contain ether oxygen atoms. The present invention also relates to the use of these PUR dispersions for coating any substrates, preferably wood substrates, such as parquet flooring.
