TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The content of filler and pigment is preferably 12-18 wt.% and 8-12 wt.% respectively. The pigment comprises titanium dioxide, zinc oxide, or antimony oxide. The filler comprises an inorganic oxide, carbonate, sulfate, silica, alkali and alkaline earth metal silicate, or baryte of a metal of Groups IA, IIA, IIIA, IIB, VIB or VIII elements of the periodic table.    TECHNOLOGY FOCUS - POLYMERS - Preferred Composition: The multilayer structure consists of a outer skin layer containing the polyamide-ionomer blend composition, an interior core layer comprising polyamide or a blend of ionomer and polyamide and optionally containing 10-30 wt.% inorganic filler, an inner skin layer comprising a polyamide-ionomer blend composition, an ionomer, polyethylene, an ionomer-polyethylene blend or an ethylene vinyl acetate copolymer and 10-20 wt.% inorganic pigment, and tie layer(s) positioned between the core layer and the outer skin layer, between the core layer and the inner skin layer, or between the core layer and each of the skin layers. The polyethylene or the ionomer-polyethylene blend comprises low-density polyethylene, linear low-density polyethylene, or high-density polyethylene, preferably high-density polyethylene. The polyamide is chosen from nylon-6, nylon-11, nylon-12, nylon-66, nylon-6,10, nylon-6,12, nylon-610/6T, nylon-612/6T, nylon-6/66, nylon-6/610, nylon-6/66/610, nylon-6/6T, nylon-1010, nylon-11 and nylon-12, nylon-66/6T, nylon-6T/DT, nylon-6I/6T, and nylon-6I/6T/66, preferably nylon-6. The tie layer comprises a maleic anhydride-grafted polymer chosen from maleated linear low-density polyethylene, maleated polypropylene, maleated styrene-ethylene-butene-styrene triblock copolymer, maleated ethylene vinyl acetate copolymers or maleated polybutadiene, and a copolymer comprising ethylene copolymerized with a functional comonomer, preferably maleated linear low-density polyethylene or maleated polypropylene. The assembly has an encapsulant layer containing ethylene vinyl acetate copolymer, olefin unsaturated carboxylic acid copolymer, ionomers of olefin unsaturated carboxylic acid copolymer, poly(vinyl acetals), polyurethane, polyvinyl chloride, polyethylene, polyolefin block copolymer elastomer, copolymers of ( alpha )-olefins and ethylenically-unsaturated carboxylic acid ester, silicone elastomer and/or epoxy resin. The assembly further has a front support layer comprising glass or fluoropolymeric sheets.
