Abstract: The present invention relates to a curable composition including: (a) at least one compound having at least one (meth)acrylic functional group in the molecule thereof, which is selected from a (meth)acrylic monomer and a (meth)acrylic oligomer; (b) an organic peroxide; (c) an o-benzoic sulfimide; and (d) an oxazoline compound, in which the component (d) is contained in an amount of 0.005 to 10 parts by mass based on 100 parts by weight of the component (a).

Abstract: The invention is concerned with an anaerobic curable composition containing (a) a compound having at least one radically polymerizable functional group in its molecule thereof, (b) an organic peroxide, (c) o-benzoic sulfimide, and (d) a complex of a metal other than alkali metals and ethylenediaminetetraacetic acid, or a complex of a metal other than alkali metals and diethylenetriaminepentaacetic acid. According to the invention, it is possible to provide an anaerobic curable composition capable of largely improving a setting time against an inert metal, while keeping preservability of the anaerobic curable composition.
