Abstract: An object of the present invention is to provide an easily disassemblable adhesive that is an adhesive for forming a structure by adhering members and enables easy disassembly of the adhered structure owing to possessing disassemblability. The invention provides a disassemblable adhesive containing an organic adhesive component and an oxidant.

Abstract: Disclosed is a gas-generating, pressure-sensitive adhesive composition comprising a pressure-sensitive adhesive (A) transmitting therethrough a radiation selected from the group consisting of an electromagnetic radiation, an electron radiation and an alpha radiation, and a gas generator compound (B) which generates a gas upon irradiation thereof with the radiation, wherein the gas generator compound (B) is operably combined with the pressure-sensitive adhesive (A), so that, in operation, when the gas-generating, pressure-sensitive adhesive composition which is adhered to an adherend is irradiated with the radiation, the gas generator compound (B) generates a gas and the gas effuses at an interface between the gas-generating, pressure-sensitive adhesive composition and the adherend to thereby facilitate release of the adherend from the gas-generating, pressure-sensitive adhesive composition.

Abstract: Disclosed is a gas-generating, pressure-sensitive adhesive composition comprising a pressure-sensitive, ultraviolet irradiation-curable adhesive (A) containing a photoinitiator, wherein the adhesive (A) transmits therethrough an ultraviolet radiation, and a gas generator compound (B) which generates a gas upon irradiation thereof with an ultraviolet radiation, wherein the gas generator compound (B) is operably combined with the pressure-sensitive, ultraviolet irradiation-curable adhesive (A), so that, in operation, when the gas-generating, pressure-sensitive adhesive composition which is adhered to an adherend is irradiated with an ultraviolet radiation, the gas generator compound (B) generates a gas and the gas effuses at an interface between the gas-generating, pressure-sensitive adhesive composition and the adherend to thereby facilitate release of the adherend from the gas-generating, pressure-sensitive adhesive composition.
