Abstract: A display film includes a transparent polymeric substrate layer and a transparent aliphatic cross-linked polyurethane layer disposed on the transparent polymeric substrate layer. The transparent aliphatic cross-linked polyurethane layer has a glass transition temperature in a range from 11 to 27 degrees Celsius and a Tan Delta peak value in a range from 0.5 to 2.5. The display film has a haze value of 1% or less.

Abstract: A display film includes a transparent polymeric substrate layer having a 0.2% offset yield stress greater than 110 MPa and a transparent aliphatic cross-linked polyurethane layer having a thickness of 100 micrometers or less disposed on the transparent polymeric substrate layer. The transparent aliphatic cross-linked polyurethane layer has a glass transition temperature in a range from 11 to 27 degrees Celsius and a Tan Delta peak value in a range from 0.5 to 2.5. The display film has a haze value of 2% or less.
