Abstract (en)
[origin: WO2008071598A1] A transparent part which comprises the following components: I. A covering layer of a polyamide polymer melt which comprises the following constituent parts: a) from 50 to 100 parts by weight of polyamide which can be produced from the following monomers: a) from 70 to 100 mol% of diamine, selected from the group containing m-xylylenediamine, p-xylylenediamine and mixtures thereof, ß) from 0 to 30 mol% of other diamines having from 6 to 14 C atoms, wherein the mol% amounts relate here to the sum of diamine, and ?) from 70 to 100 mol% of aliphatic dicarboxylic acids having from 10 to 18 C atoms, and d) from 0 to 30 mol% of other dicarboxylic acids having from 6 to 9 C atoms, wherein the mol% amounts relate here to the sum of dicarboxylic acid; b) from 0 to 50 parts by weight of another polyamide, wherein the parts by weight of a) and b) add up to 100, II. a substrate of a polymer melt on the basis of a largely amorphous polymer, wherein a) the covering layer, a possibly present adhesive promoter layer and possibly present further layers do not comprise any particle-shaped additives which reduce the transparency discernibly and b) with a layer thickness of 1 mm, the substrate has a maximum of at least 30% in the transmission curve within the visible spectrum from 380 to 800 nm, is scratch-resistant, chemical-resistant and suitable for optical applications.
