    摘要： A transparent component, which comprises the following subcomponents: I. an outer layer composed of a polyamide moulding composition, which comprises the following constituents: a) from 50 to 100 parts by weight of polyamide, which can be prepared from the following monomers: α) from 70 to 100 mol % of diamine, selected from m-xylylenediamine, p-xylylenediamine and mixtures thereof, β) from 0 to 30 mol % of other diamines having from 6 to 14 carbon atoms, where the mol % data here are based on the entirety of diamine, and also γ) from 70 to 100 mol % of aliphatic dicarboxylic acids having from 10 to 18 carbon atoms and δ) from 0 to 30 mol % of other dicarboxylic acids having from 6 to 9 carbon atoms, where the mol % data here are based on the entirety of dicarboxylic acid; b) from 0 to 50 parts by weight of another polyamide, where the parts by weight of a) and b) give a total of 100, II. a substrate composed of a moulding composition based on a substantially amorphous polymer, where a) the outer layer, any adhesion-promoter layer present, and also any further layers present comprise no particulate additives which discernibly reduce transparency and b) the substrate has, within the visible spectrum from 380 to 800 nm, a maximum of at least 30% in the transmittance curve, at a layer thickness of 1 mm, is scratch-resistant and chemicals-resistant and suitable for optical applications.
