Abstract

In order to provide a moulding composition which makes it possible to form shaped components having not only one but two or more visible sides, it is proposed that this composition comprise a methyl-methacrylate-based syrup and up to 85%, expressed in terms of the moulding composition, of an inorganic filler, and that the moulding composition comprise deformable, propellant-filled hollow microspheres having a plastic wall which is essentially insoluble in methyl methacrylate, the proportion by volume of the hollow microspheres to the total volume of the moulding composition being in the 5 to 50 vol. % range.
