| abstract |
A coating formulation contains the following components (A), (B) and (C): (A) an organic acid-titanium compound having at least one titanium atom and at least one C 2-12 aliphatic organic acid residual group as essential constituents and having no constituent other than the essential constituents, (B) fine particles of a titanate-based compound, said fine particles having an average particle size of from 10 to 100 nm, and (C) an organic solvent. A content of the components (A) is from 0.1 to 1.5 mol/kg in terms of titanium atoms, and a content of the component (B) is from 0.1 to 1.5 mol/kg in terms of titanium atoms. A production process for a titanate-based ceramic film, which makes use of the coating formulation, is also disclosed. |
