Abstract
Abstract A recording medium is provided which comprises having an ink receiving layer containing a polymer complex of a basic polymer and an acidic polymer. A recording method is also provided which performs recording by forming liquid droplets of a recording liquid and permitting the liquid droplets to attach on the surface of a recording medium, wherein the recording liquid is an aqueous ink and the surface of the recording medium contains a polymer complex of a basic polymer and an acidic polymer.
