Multilayer polyurethane protective films

A touch screen protector formed from a multilayer film comprising:

• a first layer comprising at least one aliphatic polyurethane, said at least one aliphatic polyurethane being a polyester-based polyurethane, a polycarbonate-based polyurethane, a polycaprolactone-based thermoplastic aliphatic polyurethane, or combination thereof, or at least one thermoplastic aliphatic polyurethane, said at least one thermoplastic aliphatic polyurethane being a polyester-based polyurethane, a polyether-based polyurethane, or combination thereof;
• a second layer comprising at least one thermoplastic aliphatic polyurethane, said at least one thermoplastic aliphatic polyurethane being a polyester-based polyurethane, a polyether-based polyurethane, or combination thereof, wherein the second layer has at least one of a different physical or chemical property than the first layer;
• and
• a PSA layer comprising at least one pressure sensitive silicone adhesive,
• wherein said first layer is bonded to one major surface of said second layer and said PSA layer is bonded to an opposite major surface of said second layer such that said second layer is sandwiched between said first layer and said PSA layer, wherein said at least one aliphatic polyurethane is the reaction product of at least one aliphatic polyol and at least one aliphatic diisocyanate, and said at least one aliphatic polyol is a polyester polyol, a polycarbonate polyol, a polycaprolactone polyol, or combination thereof.
