Abstract
An adhesive composition comprising 2-cyanoacrylate and at least one compound selected from the group consisting of R.sub.1 --CH.sub.2 OH, ##STR1## R.sub.1 --CHO, R.sub.1 --CHO hydrate, ##STR2## pentafluorophenol, hexachloroacetone, hexachloroacetone hydrate, chloral and chloral hydrate as cationic-polymerization inhibitor. In the above formulas, R.sub.1 is a fluorinated alkyl or aryl group having up to 12 carbon atoms, and R.sub.2 and R.sub.3 are fluorinated or non-fluorinated alkyl or aryl groups having up to 12 carbon atoms. The above adhesive composition has an excellent storage stability and an improved bonding strength.
