Embodiment Construction

[0038] In this respect, the interior trim part has a top layer 3 made of polyvinylchloride (PVC) and provided with an outer clear coat 2 . In this embodiment, the top layer 3 itself is likewise transparent, in particular only pigmented to an extent of approximately only 30%, so that a certain percentage of the light incident on its rear side passes through.

[0039] Arranged inside the entire layer composite is an opaque (ie non-transparent) layer 4 in the form of a sheet mask or membrane provided with openings and transparent only in the openings 8 of the mask or membrane. The opaque layer 4 directly adjoins the rear side of the top layer 3 in the direction of the carrier layer 7 . The base material of the opaque layer 4 consists of PVC and is the same as that of the top layer 3 .

[0040] A plurality of further transparent plastic layers, in particular a transparent / translucent plastic foam layer 5 , and also a transparent adhesive layer 6 are arranged below the opaque laye...

Abstract

The invention relates to a multilayer composite film made of plastic as a surface coating for an object, which composite film is at least partially light-permeable, i.e. in some portions, and comprises at least one outer light-permeable cover layer, optionally provided with a light-permeable lacquer, and also comprises, on the rear face of the cover layer, one or more additional light-permeable plastic layers and a light-permeable backing layer. An opaque layer, which is designed as a planar mask or screen provided with openings and is only light-permeable in the openings in the mask or screen, is arranged within the layer composite. The opaque layer adjoins the rear face of the cover layer in the direction of the support layer. The base material of the opaque layer is the same as that of the cover layer.

Description

technical field [0001] The invention relates to a multilayer composite film made of plastic and in the form of a surface coating for an article, wherein the composite film is at least partially transparent (i.e. transparent in a partial area of ​​its surface) ; have at least one outer transparent top layer optionally provided with a transparent coating; and have one or more additional transparent plastic layers, and also a transparent carrier layer on the rear side of the top layer, wherein the opaque (ie non-transparent) layer Arranged inside the layer composite, the opaque layer is in the form of a sheet mask or membrane provided with openings and is transparent only in the openings of the mask or membrane. The invention likewise relates to a method for producing such membranes, and to specific uses. Background technique [0002] Films in the form of multilayer composite films for coating or as the surface of any kind of article are widely used in the prior art, for examp...
