Abstract
A dispersion liquid according to the present invention is a dispersion liquid containing metal oxide particles which have been surface-modified with a silane compound and a silicone compound, in which, when the dispersion liquid is dried by vacuum drying to separate the metal oxide particles, and a transmission spectrum of the separated metal oxide particles is measured in a wavenumber range from 800 cmto 3800 cmwith a Fourier transform infrared spectrophotometer, Formula (1) below: IA/IB≤3.5 is satisfied (in the formula, 'IA' represents a spectrum value at 3500 cmand “IB” represents a spectrum value at 1100 cm).
