PROBLEM TO BE SOLVED: To provide a recording medium having good ink absorbency and resolution and excellent water resistance. SOLUTION: The recording medium has an ink receiving layer composed of inorganic fine particles such as alumina hydrate and a cationic polymer having a crosslinkable group. The cationic polymer is (1) a copolymer of a monomer containing a cationic monomer and a crosslinkable monomer, and (2) a cationic monomer, a crosslinkable monomer and a hydrophilic monomer. May be a copolymer of monomers containing As the crosslinkable monomer, a monomer having a hydrolytic condensable group such as an alkoxysilyl group can be used. Further, a (meth) acrylate having a polyoxyalkylene unit can be used as the hydrophilic monomer. |
