Abstract

A coating liquid including one or more of metal complexes selected from a metal complex A represented by Chemical Formula 1, a metal complex B represented by Chemical Formula 2, and a metal complex C represented by Chemical Formula 3. M in Formula 1, 2 and 3 represents a metal ion. Each of X₁-X₄ in Formula 1, 2 and 3 is one of O, NH, CO₂ and S. Each of Y₁-Y₈ in Formula 1 and Y₁-Y₄ in Formula 3 is either CH or N. Each of Z₁-Z₃ in Formula 2 and 3 and Z₄-Z₆ in Formula 2 is one selected from a group of O, NH and S, and two selected from a group of CH and N. L represents an axial ligand. k represents a valence of each of the metal complexes and is equal to a sum of electric charges of M, X₁-X₄ and L.
