An ink jet recording material which enables the recorded ink images to exhibit enhanced light fastness, water resistance and hot moisture resistance, includes an ink receiving layer formed on a support material and containing a light fastness-enhancing agent containing hydroquinone-β-D-glucoside, a salt of pyrocatechol-3,5-disulfonic acid and/or salt of p-hydroxybenzenesulfonic acid, and an inorganic pigment and a cationic polymeric material which are in the form of a plurality of composite particles prepared by mixing an aqueous dispersion of inorganic pigment particles with a cationic polymeric material having a molecular weight of 100,000 or more, to cause the aqueous dispersion of the inorganic pigment particles to be coagulated with the cationic polymeric material, and subjecting the resultant coagulate of the inorganic pigment with the cationic polymeric material to pulverization to form inorganic pigment-cationic polymeric material composite particles having an average composite particle size of 10 to 1,000 nm. |
