Polyamide Blend Film

Abstract

A film whose outer layer is composed of a molding composition which is in essence composed of the following components: a) from 3 to 50% by weight of a polyamide, selected from the group of PA11 and PA12, and b) from 50 to 97% by weight of a polyamide, selected from the group of PA1012 and PA1212, where the percentages are based on the entirety of components a) and b), is suitable for decoration of moldings which retain their gloss during their service time.

1 . A film whose outer layer is composed of a molding composition which is in essence composed of the following components:
 a) from 3 to 50% by weight of a polyamide, selected from the group of PA11 and PA12, and   b) from 50 to 97% by weight of a polyamide, selected from the group of PA1012 and PA1212,   where the percentages are based on the entirety of components a) and b).   
     
     
         2 . The film as claimed in  claim 1 , which is composed only of that layer. 
     
     
         3 . The film as claimed in  claim 1 , which is composed of two or more layers. 
     
     
         4 . The film as claimed in  claim 3 ,
 which   comprises a color layer, a carrier layer, and/or an adhesion-promoter layer.   
     
     
         5 . The film as claimed in  claim 4 ,
 wherein   the color layer and/or the carrier layer comprises a polyamide elastomer or an impact-modifying rubber.   
     
     
         6 . The film as claimed in  claim 1 ,
 whose   thickness is from 0.02 to 1.2 mm.   
     
     
         7 . The film as claimed in  claim 1 ,
 wherein   the thickness of the outer layer is from 0.01 to 0.5 mm.   
     
     
         8 . The film as claimed in  claim 1 ,
 which   is produced via extrusion, coextrusion, or lamination, and is then, if appropriate, formed.   
     
     
         9 . The method of using a molding composition which in essence is composed of the following components:
 a) from 3 to 50% by weight of a polyamide, selected from the group of PA11 and PA12, and   b) from 50 to 97% by weight of a polyamide, selected from the group of PA1012 and PA1212,   where the percentages are based on the entirety of components a) and b),   for production of a film as claimed in  claim 1 .   
     
     
         10 . A composite part, composed of a film as claimed in  claim 1  and of a substrate. 
     
     
         11 . The composite part as claimed in  claim 10 ,
 which   is a bodywork part of a motor vehicle, a constituent of the motor-vehicle interior, a cladding, a decorative strip, a cover strip, a panel, or a decorative element.   
     
     
         12 . The composite part as claimed in  claim 10 ,
 which   is produced via adhesive-bonding, pressing, lamination, or coextrusion, or via reverse coating by an injection-molding, foaming, or compression-molding method.
