1. A dispersion liquid comprising:
modified silica particles that comprise particles containing silica and a coating layer disposed on a surface of the particles containing silica,
an organic solvent; and
water,
wherein the coating layer includes a reactant of a reactive group on the particles containing silica surface-treated with a compound A represented by Formula A and a functional group of a compound B having the functional group and an organic group, wherein the organic group of the compound B includes at least one structure selected from the group consisting of a polyester structure, a poly(meth)acrylate structure, a polyolefin structure, and a polyether structure,
wherein a content of water is 0.1 to 20.0 mass % with respect to a total mass of the modified silica particles,
Si(RA)4-n(XA)n  Formula A
in Formula A, RA represents a monovalent organic group including the reactive group, XA represents a hydroxyl group or a monovalent hydrolyzable group, and n represents an integer of 1 to 3, in a case where n is 2 or less, a plurality of RA's may be the same or different from each other, the reactive group contained in RA in Formula A is an ethylenically unsaturated group, a thiol group, an epoxy group, or an amino group.
