More Information
Summary:The invention provides a surface protection sheet, the outermost surface of a base material layer is roughed to a degree that the presence of a foreign body between the surface protection sheet and an adherend is unobvious, and whether an adherend with a smooth surface or an adherend with a rough surface both can exhibit sufficient and appropriate adhesion to the surface protection sheet. The surface protection sheet successively comprises a white series base material layer, a black series base material layer and an adhesive layer, the white series base material layer is the outermost layer, the surface roughness Ra of the outermost surface of the white series base material layer is above 0.30 mum, the surface fluctuation degree Wa of the outermost surface of the white series base material layer is 0.40-0.60 mum, and the surface gloss, at 60 degree gloss, of the outermost surface of the white series base material layer is below 65.
