TRANSPARENT MULTILAYER SHEET HAVING ELECTROSTATIC DISSIPATIVE PROPERTIES |
摘要 |
<p>Disclosed is a transparent multilayer sheet that is excellent in antistatic properties, as well as transparency. The transparent multilayer sheet includes a surface layer comprising a conductive thermoplastic polyurethane or polyurea resin containing ethylene oxide; and a back layer attached to the surface layer and comprising a transparent non-conductive polymer resin. Preferably, the polyurethane or polyurea resin is a polymerization product of (a) a polyether-based polymer containing ethylene oxide and reacting with an isocyanate group; (b) an aromatic or aliphatic diisocyanate compound; and (c) a chain extender C2 to C10 containing a primary hydroxyl group or an amine group, and the transparent non-conductive polymer resin is selected from the group consisting of polyethylene terephthalate, glycol modified polyethylene tereph-thalate, glycol modified polycyclohexaneterephthalate, polymethylmethacrylate, polycarbonate, transparent acrylonitrile-butadiene-styrene (ABS), and mixtures thereof.</p> |
