Abstract
Multi-layer protective sheets of the invention are both rigid enough to provide desired protective properties, but flexible enough to be formable into a desired non-planar shape in order to protect surfaces such as optical display surfaces of electronic devices. Once formed into the desired non-planar shape, a modified interlayer of the multi-layer protective sheet has a shear storage modulus of greater than about 100 MPa.
