Beschreibung
Zusammenfassung:	Improved impact or shock resistant laminates comprising a plurality of lamina including a back polycarbonate lamina opposite the direction of impact or shock, such back polycarbonate lamina having a relatively hard and brittle overlying or exposed layer or coating opposite the direction of impact, are provided by interposing intermediate layer between said hard and brittle exposed layer and the polycarbonate lamina which intermediate layer is softer and less brittle than said exposed layer, such intermediate layer reducing failure and spalling of the polycarbonate surface opposite the impact or shock receiving surface.
