An object of the present invention is to provide a composition having excellent storage stability. A mixed composition of an organosilicon compound (C) having an amino group or an amine skeleton, a solvent 1, and a solvent 2, comprising a hydrogen bonding term (δH) and a dispersion term (δD) in Hansen solubility parameters A mixed composition in which the ratio (δH/δD) of solvent 1 is less than 0.410 and the ratio (δH/δD) of solvent 2 is 0.410 or more, where the ratio (δH/δD) of solvent 1 is 0.410 or more.
