An object of the present invention is to provide a compound suitable for use as a latent curing agent, which does not produce an aldehyde compound when caused to react with an isocyanate compound. The present invention provides, as the compound, a silylamine compound represented by the following formula (1): in the formula (1), Rto Reach independently represent an alkyl group having 1 to 6 carbon atoms, Rrepresents an alkylene group having 2 to 12 carbon atoms or an arylene group having 6 to 12 carbon atoms, Rto Reach independently represent a hydrogen atom or an alkyl group having 1 to 6 carbon atoms, 'y' and “z” each independently represent an integer of from 1 to 11, and “n” represents an integer of from 1 to 43.

Silylamine compound and latent curing agent comprising said silylamine compound

A one-component type curable composition includes: an isocyanate group-containing urethane prepolymer (A) obtained by allowing a polyoxyalkylene-based polyol (a-1) having a number average molecular weight of 1,000 or more and less than 3,000, a polyol (a-2) having a number average molecular weight of less than 1,000, an epoxy (meth)acrylate (a-3) containing two or more hydroxyl groups in one molecule, and isophorone diisocyanate (a-4) to react with each other; a compound (B) having an oxazolidine ring; a first curing accelerator (C) configured to accelerate a reaction between at least one of a secondary amino group or a hydroxyl group generated by hydrolysis of the (B) and an isocyanate group of the (A); and a second curing accelerator (D) configured to accelerate the hydrolysis of the (B).
