Patent ID: 8030428

Claim:
A curable composition comprising an oxyalkylene polymer (A) having a reactive silicon group represented by the following formula (1), and a quaternary ammonium salt (B) represented by the following formula (2): —SiX 1 a R 1 3-a (1) wherein R 1 is a C 1-20 monovalent organic group which may have a substituent, X 1 is a hydroxyl group or a hydrolyzable group, and a is an integer of from 1 to 3; provided that when plural R 1 s are present, they may be the same or different from one another, and when plural X 1 s are present, they may be the same or different from one another wherein each of R 2 to R 5 is independently a C 1-25 linear or branched saturated or unsaturated hydrocarbon group, and X 2 is an organic acid ion, an inorganic acid ion or a hydroxyl group, wherein 2 or 3 groups among R 2 to R 5 are C 6-25 linear or branched saturated or unsaturated hydrocarbon groups, and the remaining groups are a C 1-5 linear or branched saturated hydrocarbon group.
