ABSTRACT:
The present invention relates to a method for making a multilayer article, wherein said multilayer article comprises: (i) a first layer comprising an acrylic resin; (ii) at least one translucent second layer comprising (a) an acrylic resin, optionally further comprising an impact modifier; (b) a rubber modified thermoplastic resin composition; (c) optionally a rheology modifier; and (d) a visual effects additive; (iii) a third layer comprising an acrylonitrile-butadiene-styrene (ABS) resin; and (iv) an optional backing layer comprising either a thermosetting polymer substrate, optionally fiber-reinforced, or glass filled ABS resin; and wherein said method comprises the steps of: (I) drying the components of the second layer, either individually or in combination, to a volatiles content of less than 0.06 weight % prior to processing a mixture comprising said components to form said second layer; and (II) coextruding the second and third layers, and optionally the first layer to form the multilayer article. In other embodiments the present invention relates to articles made by the method.
