Abstract:
1. A multilayer article, which comprises in sequence: (i) a first layer comprising an acrylic resin having a thickness in a range of between about 0.007 millimeters and about 3 millimeters; (ii) at least one translucent second layer having a thickness in a range of between about 0.5 millimeters and about 5 millimeters and comprising (a) an acrylic resin present in an amount in a range of between about 95 phr and about 50 phr, and optionally further comprising an impact modifier; (b) a rubber modified thermoplastic resin composition present in an amount in a range of between about 5 phr and about 50 phr and comprising a discontinuous elastomeric phase dispersed in a rigid thermoplastic phase, wherein at least a portion of the rigid thermoplastic phase is grafted to the elastomeric phase, wherein said thermoplastic phase comprises structural units derived from at least one vinyl aromatic monomer and at least one monoethylenically unsaturated nitrile monomer; (c) optionally a rheology modifier present in an amount in a range of between 0 phr and about 5 phr; and (d) a visual effects additive present in an amount in a range of between about 1 weight % and about 65 weight % and selected from the group consisting of pigments, glass-based pigments, fillers, mineral flakes, mineral fibers, mica, aluminum flakes, cellulosic flakes, cellulosic fibers, and crosslinked resinous particles having particle size in the range of 0.15 to 3 millimeters, wherein phr values are based on the resinous components of the second layer and wherein weight % values are based on the weight of the entire second layer; (iii) a third layer directly contacting said second layer comprising an acrylonitrile-butadiene-styrene (ABS) resin, said layer having an impact resistance greater than 350 Newtons per meter according to ASTM D256, and having a thickness either in a range of between about 2 millimeters and about 3.8 millimeters or in a range of between about 3.8 millimeters and about 12 millimeters; and (iv) an optional backing layer comprising either a thermosetting polymer substrate, optionally fiber-reinforced, or glass filled ABS resin, and having a modulus of at least 1000 MPa according to ISO 178.
