Patent ID: 8013079

Claim:
A non-organotin-based curable composition which comprises: (A) an organic polymer having a silicon-containing group capable of crosslinking by siloxane bond formation, wherein the (A) component organic polymer is at least one polymer selected from the group consisting of polyoxyalkylene polymers, saturated hydrocarbon polymers and (meth)acrylate ester polymers, (B) a biguanide compound represented by the general formula (4): R 10 N═C(NR 11 2 )—NR 12 —C(═NR 13 )—NR 14 2 (4) (wherein R 10 , the two R 11 moieties, R 12 , R 13 and the two R 14 moieties each independently is a hydrogen atom or a non-aryl monovalent organic group; any two or more of R 10 , the two R 11 moieties, R 12 , R 13 and the two R 14 moieties may be bound together to form a ring structure) and/or the general formula (5): R 15 N═C(NR 16 2 )—N═C(NR 17 2 )—NR 18 2 (5) (wherein R 15 , the two R 16 moieties, the two R 17 moieties, and the two R 18 moieties each independently is a hydrogen atom or a non-aryl monovalent organic group; any two or more of R 15 , the two R 16 moieties, the two R 17 moieties and the two R 18 moieties may be bound together to form a ring structure).
