PROBLEM TO BE SOLVED: To provide a curable composition containing an organic polymer having a reactive silicon group, which has good curability, adhesion, restorability, and storage stability without containing an organotin compound.SOLUTION: The curable composition includes: an organic polymer (A) having a reactive silicon group (trimethoxysilyl group, (methoxymethyl)dimethoxysilyl group or the like) represented by formula (1): -SiR1aR2(3-a-b)Xb; an acidic compound (B) selected from lewis acids or carboxylic acids; and an amine compound (C). In the formula (1), R1 is a 1-20 C hydrocarbon group, wherein the hydrogen on the carbon at the 1-position is substituted with any of halogen atoms, O, N and S; R2 is a 1-20C unsubstituted hydrocarbon group; X is a hydroxyl group or hydrolyzable group; a is 0-2 and b is 1-3, with the proviso that when a=0, b=3, when a≥1, a+b≤3; and when a plurality of R1 groups and X groups are present, they may be the same or different. |
