Abstract
The present invention relates to compositions comprising at least one thermoplastic polyurethane and at least one poly(meth)acrylate, where the at least one thermoplastic polyurethane is a polyurethane based on hexamethylene 1,6-diisocyanate (HDI), on at least one diol, and on at least one chain extender, selected from the group consisting of ethylene 1,2-glycol, 1,2-propanediol, 1,3-propanediol, 1,4-butanediol, 2,3-butanediol, 1,5-pentanediol, 1,6-hexanediol, diethylene glycol, dipropylene glycol, 1,4-cyclohexanediol, 1,4-dimethanolcyclohexane, and neopentyl glycol. The present invention further relates to moldings comprising the compositions of the invention, and also to the use of the compositions of the invention for producing a foil and for coating a molding.
