TECHNOLOGY FOCUS - CERAMICS AND GLASS - The back sheet is selected from glass sheets and ceramic plates. The front sheet is selected from glass sheets.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - The filler is selected from calcium carbonate, magnesium carbonate, barium carbonate, magnesium sulfate, barium sulfate, calcium sulfate, zinc oxide, magnesium oxide, calcium oxide, titanium oxide, alumina, aluminum hydroxide, hydroxyapatite, silica, mica, talc, kaolin, clay, glass powder, asbestos powder, zeolite, clay silicate and/or coal fly ash (preferably titanium oxide having a refractive index of greater than or equal to 2.5). The back sheet is selected from metal sheets.    TECHNOLOGY FOCUS - POLYMERS - The first polymeric material is selected from polyolefins, polyurethanes and/or poly(vinyl butyrals) or ethylene copolymer comprising copolymerized units of ethylene and a polar monomer (preferably ethylene/vinyl acetate copolymers, ethylene/acrylic acid copolymers, ethylene/methacrylic acid copolymers, ethylene/acrylate copolymers, ethylene/methacrylate copolymers, ionomers, and/or copolymers of ethylene and monoester, diester or anhydride of 4-8C unsaturated acids having two carboxylic acid groups). The third polymeric material is selected from ethylene homopolymers, ethylene copolymers, propylene homopolymers and/or propylene copolymers (preferably ethylene/vinyl acetate copolymers, ethylene/acrylic acid copolymers, ethylene/methacrylic acid copolymers, ethylene/acrylate copolymers, ethylene/methacrylate copolymers, ionomers and/or copolymers of ethylene and monoester, diester or anhydride of 4-8C unsaturated acids having two carboxylic acid groups). The back sheet is selected from polymeric sheets and polymeric films. The polymeric sheets comprise a polymer selected from polycarbonates, acrylics, polyacrylates, cyclic polyolefins, polystyrenes, polyamides, polyesters and/or fluoropolymers; and the polymeric films comprise a polymer selected from polyesters, polycarbonates, polyolefins, norbornene polymers, polystyrenes, styrene-acrylate copolymers, acrylonitrile-styrene copolymers, polysulfones, nylons, polyurethanes, acrylics, cellulose acetates, cellophanes, poly(vinyl chlorides) and/or fluoropolymers. The front encapsulant comprises a polymeric material selected from ethylene/vinyl acetate copolymers, ethylene/acrylic acid copolymers, ethylene/acrylate copolymers, ionomers, poly(vinyl acetals), polyurethanes, poly(vinyl chlorides), polyethylenes, polyolefin block elastomers, silicone elastomers and/or epoxy resins, and the front sheet is selected from polymeric sheets, and polymeric films.
