A silicone-based pressure-sensitive adhesive comprises (A) a partial condensation product or a mixture of (a) a crude rubber-like organopolysiloxane having an average of at least one alkenyl group per molecule, and (b) an organopolysiloxane resin consisting essentially of R<img id="custom-character-00001" he="2.46mm" wi="1.44mm" file="US20070059535A1-20070315-P00900.TIF" alt="custom character" img-content="character" img-format="tif"/>1??3#191SiO?1/2#191 units and SiO?4/2#191 units; (B) an organopolysiloxane having an average of at least two silicon-bonded hydrogen atoms per molecule; (C) an aromatic amine compound, and/or an organopolysiloxane that contains aromatic amino groups; and (D) a platinum catalyst. The pressure-sensitive adhesive forms a pressure-sensitive adhesive layer that is easily repeelable after being exposed to a high temperatures.
