Japanese Patent JP7351310

B2

The present invention is a mixed composition containing a biaryl compound, an active hydrogen compound, and an organic solvent Y. The biaryl compound has a structure that is represented by general formula (1) and that contains a group capable of intramolecular hydrogen bonding, the active hydrogen compound has a structure represented by general formula (2), and the organic solvent Y is liquid at room temperature. General formula (2): Z-X [Ring A and ring B each represent a five-membered or six-membered aromatic hydrocarbon ring or aromatic heterocyclic ring, and at least one of ring A and ring B is an aromatic heterocyclic ring. A1 and B1 each represent a carbon atom, a nitrogen atom, an oxygen atom, or a sulfur atom, and at least one of A1 and B1 represents a nitrogen atom, an oxygen atom, or a sulfur atom. A2 to A5 and B2 to B5 each represent a carbon atom, a nitrogen atom, an oxygen atom, or a sulfur atom. n and m each represent an integer equal to 1 or 2, and L represents a single-bond, oxygen atom or nitrogen atom. Z represents a polar group capable of hydrogen bonding, and X represents a substituent group that does not inhibit hydrogen bonding.]
