Abstract
A recording medium includes a substrate and an ink-receiving layer as the top layer. The ink-receiving layer contains inorganic particles. The inorganic particles contain cationized colloidal silica, alumina hydrate, and fumed alumina. A content of the cationized colloidal silica is 5% or more by mass and 25% or less by mass based on a content of the inorganic particles. The mass ratio of the alumina hydrate to the fumed alumina (alumina hydrate content:fumed alumina content) is from 95:5 to 55:45.
