<p>A curable composition which has curability even at temperatures as low as -20 to 5 °C, has a low viscosity at a low temperature, and gives a cured article satisfactory in material properties such as water resistance, chemical resistance, and mechanical properties. The composition comprises (A) a heterocyclic compound represented by general formula (1), (B) a compound having per molecule two or more electrophilic groups reactive with a thiol or -S- group, and (C) a compound having two or more nucleophilic groups per molecule. In said formula, n is an integer of 1 to 10; X?1, Y1, and Z1¿ each independently is oxygen or sulfur; R1 is either a residue of (D) a compound having a cyclic ether group or hydrogen; and R2 is a C¿2-10? hydrocarbon group.</p> |
