Abstract
An inkjet recording medium includes a support and an ink-receiving layer which is disposed on the support and which contains an alumina pigment and an alkylsulfonic acid having the carbon number of 1 or more and 4 or less. The ink-receiving layer further contains a polymeric compound, a water-soluble zirconium compound, and boric acid or a borate. The polymeric compound is one obtained by cationizing at least one amino group of a product with acid, the product being obtained by the reaction of at least three compounds, that is, (i) a sulfur-containing organic compound containing two or more active hydrogen atoms, (ii) a polyisocyanate compound containing two or more isocyanate groups, and (iii) an amine compound containing two or more active hydrogen atoms.
