Abstract: Water-based polyurethane dispersion methodology relating to a chain-extended polyurethane, characterized in that the polyurethane dispersion includes 2, 5, 7, 10-tetraoxaundecane. The water-based polyurethane dispersion is suitable as a non-hazardous water-based coating composition for coatings with a particularly good adhesion on plastic or rubber substrates. The solvent 2, 5, 7, 10-tetraoxaundecane contained therein imparts good film coalescing, good adhesive properties and high strength of the polyurethane dispersion.

Abstract: The invention relates to opaque colored multilayer articles having a substrate layer based on polycarbonate or polymethylmethacrylate. The compositions of the substrate layer contain a titanium dioxide having particular properties as white pigment. Compared to the Kronos® 2230 white pigment which is conventionally used as white pigment for corresponding compositions and has more particularly been specially matched to polycarbonate, it is possible to achieve considerably higher weathering stability of the colored shaped bodies provided that a UV absorber-containing coating has been applied to the substrate layer. Color stability and gloss are maintained even after weathering, and brilliant colors can thus be assured.
