  • Patent number: 6903156
    Abstract: 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.
