A method for adhering an artificial nail to a natural nail by the use of an adhesive comprising at least one of .alpha.-cyanoacrylates of the formula: ##STR1## wherein R is n-propyl, isopropyl, n-butyl, isobutyl, methoxyethyl, ethoxyethyl or etrahydrofurfuryl. This method does not generate heat and assures easy removal of the adhesion with a conventional solvent.

Method for adhering artificial nail

An adhesive composition enhanced in initial adhesion strength which comprises (A) an .alpha.-cyanoacrylate ester, (B) at least one chosen from aliphatic polyols and their derivatives and polyethers and their derivatives and (C) at least one chosen from aromatic polyols and their derivatives and carboxylic acids and their derivatives.

Adhesive composition

An adhesive composition which comprises an .alpha.-cyanoacrylate compound with a certain ester ether compound and, preferably, a polyhydroxybenzoic acid compound. The composition is enhanced in heat shock resistance and improved in initial adhesion rate.
