The purpose of the present invention is to provide an organic metal compound-containing composition that has excellent liquid stability, a long pot life, and excellent productivity. This organic metalcompound-containing composition is characterized by containing: at least one organic metal compound (A) selected from the group consisting of metal alkoxides and metal chelates; and a polymerizable compound (B) having a polymerizable functional group and a carboxyl group. The metal of the organic metal compound (A) is preferably titanium, and the polymerizable compound (B) is preferably a radicalpolymerizable compound.
