Abstract

Multilayer articles comprising a coating layer comprising resorcinol arylate chain members bound to a support substrate via an optional intermediate tie layer. Adhesion between the layers of the multilayer article is enhanced by modifying at least a part of a surface of at least one of the layers in the multilayer article by a technique selected from at least one of: surface adhesive treatment, surface corona treatment, flame treatment, plasma surface treatment, vacuum deposition treatment, ionization radiation, chemical surface treatment, surface abrasion treatment, and surface texturing treating.

         7 . An article produced in accordance with the method of  claim 2 . 
     
     
         8 . An article having a weatherable outer surface with a high quality finish appearance, said article is produced by the following method:
 thermoforming an outer layer comprising resorcinol arylate polyester chain members into a three-dimensional shape in a vacuum-forming apparatus;   placing said three-dimensional shape in a cavity of an injection molding apparatus; and   injecting a flowable resin into the cavity of said injection molding apparatus behind said layer comprising resorcinol arylate polyester chain members to form a multi-layer article.   
     
     
         9 . A method for producing an article having a weatherable outer surface with a high quality finish appearance, said method comprising:
 laminating an outer layer onto a metal substrate forming a laminate composite, wherein the outer layer comprises resorcinol arylate polyester chain members;   thermoforming said laminate composite into a three-dimensional shape in a vacuum-forming apparatus;   placing said three-dimensional shape in a cavity of an injection molding apparatus; and   injecting a flowable resin into the cavity of said injection molding apparatus behind said metal substrate of said thermoformed laminate composite to form a multi-layer article.   
     
     
         10 . The method of  claim 9 , wherein said metal substrate is a chrome foil or Al foil. 
     
     
         11 . An article produced in accordance with the method of  claim 9 . 
     
     
         12 . In a coextrusion process for preparing a composite polymer film construction having at least two layers wherein the polymers in the layers are fusion-bonded to each other and wherein: a) polymer resins forming said layers are fed into separate channels of a film die as separate streams, b) the polymer streams flow into the film die and are extruded to form an extrudate in which the polymer streams form a film having fusion-bonded layers, the improvement consists of employing resorcinol arylate polyester chain members to form a surface layer of said polymer film construction.
