LIGHT-PERMEABLE MULTI-LAYER COMPOSITE FILM

The invention relates a light-permeable multi-layer composite film made from plastic as a surface coating for an object, the composite film comprises at least one outer at least partially light-permeable covering layer and optionally provided with a covering, and at least one additional layer arranged on the rear side of the cover layer, an optical layer being arranged on the rear side of the cover layer, the optical layer being preferably an optical layer comprising polyethylene terephthalate (PET) and having light transmitting, light refractive, and light reflective properties or a combination thereof, and the transmitting, refractive and reflective properties being designed in such a way that an illumination of the optical layer, in particular a rear-side illumination of the optical layer, leads to a preferably evened-out passage of light through the cover layer. 披露了一种由塑料制成的作为制品的表面涂层的可透光多层复合膜，其中，该复合膜包括任选地设有漆的至少一个外部的至少部分可透光的顶层和布置在该顶层的背面上的至少一个另外的层，其中，布置在该顶层的背侧上的是光学层，优选是由聚对苯二甲酸乙二醇酯(PET)制成的光学层，该光学层具有光透射、光折射和光反
