The one-part water-based adhesive composition includes (A) an aqueous dispersion of a polyurethane resin and (B) a silane compound obtained by reacting a specific epoxysilane compound with an aminosilane compound represented by the following Formula (2), the amount of the epoxysilane compound being in the range of 1.5 to 10 mol per 1 mol of the aminosilane compound, at a reaction temperature of 40 to 100° C. (In Formula (2), R7 to R12 are each a hydrogen atom or an alkyl group, R13 is a monovalent hydrocarbon group, R14 is an alkyl group, and b is 0 or 1.)

    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.
