Claim:
A curable composition containing: a halogen-containing crosslinking polymer, and a thiol compound derivative selected from the group consisting of: having, in one molecule, at least one functional group represented by the following formula (17): wherein A is an oxygen atom or a sulfur atom, R 1 is a hydrogen atom, an alkyl group or a phenyl group, R 2 is a group selected from the group consisting of the following groups (a) to (f), R 3 is a hydrogen atom, an alkyl group or a phenyl group; (a) a group selected from an alkyl group, a halogenated alkyl group, an alkyl group having at least one hydroxyl group, an alkenyl group, an alkynyl group and an aralkyl group, b) a residue wherein a hydroxyl group is removed from a hydroxyl group-containing compound selected from alkylene glycol, dialkylene glycol, trialkylene glycol, tetraalkylene glycol, allyl alcohols, ketooximes, alkanolamines, dialkanolamines, trialkanolamines, trialkylsilanol, alicyclic alcohol and naphthyl alcohols, (c) a group represented by the following formula (3): —CHY—CH 2 X (3) wherein X is any one of a halogen atom, an alkoxy group, an alkoxyalkoxy group, a dialkylamino group, a trialkylsilyl group, an acetoxy group and a piperidino group, and Y is a hydrogen atom or a halogen atom, (d) a group represented by the following formula (4): wherein Z is any one of a hydrogen atom, a halogen atom, a nitro group, an amino group, an alkoxy group, an alkylamino group, a dialkylamino group, an alkyl group and an acyl group, and n is an integer of 1 to 3 and is a number of substituents Z bonded to the phenyl group skeleton in the formula (4), (e) a group represented by —CH 2 —C 6 H 5 or H —CHCH 3 —C 5 H 5 , and (f) a group represented by the following formula (5) or (6): —R 4 -ACH═CH 2 (5) wherein R 1 and R 3 are the same as Rand R 3 in the formula (2), A is an oxygen atom or a sulfur atom, and R 4 is any one of —CH 2 —, —CH 2 —CH 2 —, —CH 2 CH 2 CH 2 —, —CH 2 CH 2 CH 2 CH 2 —, —CH 2 CH 2 OCH 2 —, —CH 2 CH 2 OCH 2 CH 2 OCH 2 CH 2—,
