Abstract

The present invention relates to materials composites of a moulded article of at least one transparent or translucent dyeable plastics moulding compound which moulded article is bonded to at least one transparent or translucent surface layer and / or to decorative films, functional films or coats or rubbers or other plastics, wherein the plastics moulding compound used for the manufacture of the moulded article, the surface layer or the other plastics contains in an amount of 0.01 to 5.0 % by weight, preferably 0.01 to 2.0 % by weight, each related to the total weight of the moulding compound, at least one lubricant selected from the group consisting of sorbitan esters, sebacic acid esters, dodecanedioic acid esters, docosanoic acid esters, glycerine, glycol, diethylene glycol, stearoyl amide, stearyl stearate, ethylene bissteroyl amide, octane pyrrolidone, and from the group consisting of non-polar paraffin oils and of tetracosanes, and wherein a permanent adhesion to the other plastics layers and / or sheets or coats or rubbers or other plastics is achieved.

Description

technical field [0001] The present invention concerns the subject matter set forth in the patent claims. More specifically, the present invention thus relates to a material composite of moldings of at least one transparent or translucent dyeable plastic molding compound, wherein the moldings are bonded to at least one transparent or translucent surface layer and / or to a decorative film, Functional films or coatings or rubber or other plastics. The plastic molding compounds used exhibit qualities that can currently only be achieved with PMMA, polycarbonate (PC) or curable casting materials. Plastic molding compounds for the materials according to the invention are in particular polyamide molding compounds. It contains a lubricant that does not impair adhesion to other parts. The material composites according to the invention can be used in optical components, such as ophthalmic or sun lenses for spectacles, magnifying lenses, lens systems, microscopes, cameras, mobile phone ...
