摘要: Provided is a method of producing a pressure-sensitive adhesive containing a cured product of a curable composition containing a crosslinkable silicon group-containing organic polymer and an adhesion-imparting resin as a pressure-sensitive adhesive layer; curing of the curable composition does not proceed when heated during production, i.e., the curable composition has excellent stability when heated, and the crosslinking reaction of the curable composition proceeds by some sort of trigger. The pressure-sensitive adhesive contains, as a pressure-sensitive adhesive layer, a cured product of a curable composition containing (A) a crosslinkable silicon group-containing organic polymer, (B) an adhesion-imparting resin, (C) a Si—F bond-containing silicon compound, and (D) a photobase generator.
