Summary:PURPOSE:To obtain the titled tape or sheet having excellent heat resistance, peelability, and light screening ability, by applying a specified black pressure- sensitive adhesive to one side of a heat-resistant synthetic resin film or paper. CONSTITUTION:A black pressure-sensitive adhesive (A) is obtained by mixing 100pts.wt. pressure-sensitive adhesive (a) composed mainly of a silicone rubber and a silicone resin (e.g., a silicone self-adhesive composed of a silicone rubber component having a straight-chain polysiloxane structure of a degree of polymerization of thousands to tens of thousands and a silicone resin component having a three-dimensional structure) with 15-50pts.wt. black iron oxide, cobalt black and/or titanium black, having an average particle diameter of 0.1-10mum. Component A is applied in a thickness of 25-70mum to one side of a 12-150mum thick heat-resistant synthetic resin film (e.g., a polyimide film) or paper (B) to give the titled tape or sheet which screens visible light and ultraviolet rays of the wavelength of 900-190nm.
