Abstract
[Problem] To provide a curable composition having high stability and excellent curing properties. [Solution] The present invention relates to a curable composition, and a cured synthetic resin using same, that functions as a curing catalyst for a synthetic resin. The curable composition contains (A) a titanium alkoxide, (B) a bidentate organic chelating agent that stabilizes the titanium alkoxide and (C) a guanidine compound. The molar ratio of the titanium alkoxide (A), the bidentate organic chelating agent (B), and the guanidine compound (C) is 1:0.5-3:0.5-2.
Claims4
