The present invention relates to aqueous self-crosslinking PU dispersions and to coatings prepared from them.

Self-crosslinking PU dispersions

The present invention relates to novel one-component polyurethane systems including one or more organic and/or inorganic compounds of vanadium in which the vanadium has an oxidation state of at least +4, to their preparation and use for preparing paints, inks and adhesives.

Polyurethane coating systems

The invention relates to aqueous and/or water-dilutable blocked polyisocyanates, their preparation and use in optionally self-crosslinking one-component systems.

Blocked polyisocyanates

The present invention relates to light fast, aqueous, strippable coating compositions containing A) 40 to 90 wt. %, based on resin solids of A) and B), of aqueous polyurethane-polyureas and B) 10 to 60 wt. %, based on resin solids of A) and B), of polymers prepared from radically polymerizable monomers, wherein the percentages of A) and B) add up to 100, based on the weight of resin solids of A) and B). The present invention relates also to substrates coated with these strippable coating compositions. In addition, the present invention relates to the use of the stripped coatings as recycled material by mechanically comminuting the stripped coatings, optionally after cleaning, and then either pressing them in heatable presses to form sheets, or extruding them in an extruder to form endless thermoplastic threads, and then processing the resulting threads by known granulating methods to form cylindrical, spherical, lenticular or rhombic granules. Finally, the present invention relates to the use of the resulting thermoplastic granules for the production of articles by known processes such as injection molding, blow molding, deep-drawing, slush molding or flat extrusion.
