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.

First claim

The invention claimed is:

1. A cured synthetic resin obtained by curing a composition comprising a polyol and a polyisocyanate in the presence of a catalyst composition including:
(A) a titanium alkoxide,
(B) a bidentate organic chelating agent for stabilizing the titanium alkoxide, and
(C) a guanidine compound;
wherein the composition comprises the titanium alkoxide (A), the bidentate organic chelating agent (B) and the guanidine compound (C) in a molar ratio of 1:0.5 to 3:0.5 to 2.

2. The cured synthetic resin according to claim 1 , wherein the bidentate organic chelating agent (B) is at least one of ethyl acetoacetate and acetylacetone, and the guanidine compound (C) is at least one of 1-phenylguanidine and 1,1,3,3-tetramethylguanidine.

3. A composition, comprising:
(A) a titanium alkoxide,
(B) a bidentate organic chelating agent for stabilizing the titanium alkoxide,
(C) a guanidine compound,
(D) a polyol, and
(E) a polyisocyanate,
wherein the composition comprises the titanium alkoxide (A), the bidentate organic chelating agent (B) and the guanidine compound (C) in a molar ratio of 1:0.5 to 3:0.5 to 2.

4. The composition according to claim 3 , wherein the bidentate organic chelating agent (B) is at least one of ethyl acetoacetate and acetylacetone, and the guanidine compound (C) is at least one of 1-phenylguanidine and 1,1,3,3-tetramethylguanidine.
