Abstract:
1. A gas-generating, pressure-sensitive adhesive composition comprising: a pressure-sensitive, ultraviolet irradiation-curable adhesive (A) containing a photoinitiator, wherein said adhesive (A) transmits therethrough an ultraviolet radiation; and a gas generator compound (B) which generates a gas upon irradiation thereof with an ultraviolet radiation, said gas generator compound (B) being operably combined with said 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.
