Abstract

Abstract A curable composition containing (a) 100 parts by weight of an oxyalkylene polymer having a silicon atom-containing group to which a hydroxyl group or a hydrolyzable group is bonded and capable of crosslinking on formation of a siloxane bond and (b) from 0.01 to 20 parts by weight of a hydrolyzable silicon compound represented by formula (1): <IMAGE> (1) wherein X represents a hydrolyzable group; R1 represents a monovalent hydrocarbon group; R2 represents a monovalent organic group containing an amino group or an imino group and having a carbon atom number to nitrogen atom number ratio (C/N ratio) of more than 3; m represents 0, 1 or 2; n represents 1, 2 or 3; and (m+n) is less than 4.
