  • Patent number: 7413624
    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.
