Abstract
A coating solution for use in the formation of a metal oxide film is described. It is composed of (a) a .beta.-diketone, (b) at least one element or compound selected from the group consisting of elements capable of forming complexes with said .beta.-diketone, salts of the elements and hydrolysates of alkoxides of the elements, and (c) an aprotic polar solvent. As an alternative, it is composed of a metal complex of a .beta.-diketone and an aprotic polar solvent.
