    Abstract: PROBLEM TO BE SOLVED: To obtain an ultraviolet-curing type removable pressure bonding composition having stable removability and an ultraviolet-curing type removable pressure bonding composition that has no change in bond strength with time even at high temperature and high humidity and slight variation of bond strength of cured coating film even in variation of ultraviolet irradiation amount during curing and does not break a substrate coated with an adhesive in use, namely, in releasing, and exhibits stable removability. SOLUTION: The ultraviolet-curing type removable pressure bonding composition comprises at least one kind of an ultraviolet-curable component selected from an ultraviolet-curable monomer and oligomer containing an acryloyl group or a methacryloyl group, a (meth)acrylic copolymer having ≤20°C glass transition temperature, a photopolymerization initiator and at least one kind of a fluorine-containing compound selected from (1) a fluorine-containing polymerizable compound, (2) a fluorine-containing copolymer having a fluorine-containing segment and a fluorine-free segment and (3) a fluorine-containing surfactant.
