摘要

PROBLEM TO BE SOLVED: To provide: a color change inhibitor which prevents color change of an ink composition containing a charge-transporting compound and an electron-accepting compound; an ink composition with suppressed color change; an organic thin film formed using the ink composition; an organic electronic element; and an organic electroluminescence element.SOLUTION: A color change inhibitor prevents color change of an ink composition containing one or more charge-transporting compounds and electron-accepting compounds, and contains a compound having a group 15 or 16 element. The ink composition contains the one or more charge-transporting compounds and electron-accepting compounds, and contains the color change inhibitor containing the compound having the group 15 or 16 element.
