The invention relates to composites VS comprising at least two plastic layers A and C, suitable for the production of articles which, on one surface, come into contact with water at temperatures between 0.degree. and 90.degree. C., wherein the layer A, which comes into contact with water, comprises a thermoplastic, impact-resistant polymethyl methacrylate plastic SP having a Vicat softening temperature of at least 95.degree. C. according to ISO 306 procedure B and a notch impact resistance of at least 3.0 kJm.sup.-2 according to ISO 180 1A, and layer C comprises an impact-resistant acrylonitrile-styrene copolymer VP. In a preferred specific embodiment of the invention, another layer B, made of a thermoplastic polymethyl methacrylate plastic P, is placed between layers A and C.
A composite suitable for the production of articles, said composite comprising a layer A, said layer A having a non-laminated outer surface which comes into contact with water exhibiting temperatures between 0.degree. and 90.degree. C., said composite comprising:
A three-dimensionally shaped sanitary article, wherein said article is formed from a composite comprising:
