<P>PROBLEM TO BE SOLVED: To provide an inkjet recording medium which can form a high-density image with high resolution and has inhibitive effect upon the generation of a bleeding phenomenon over time, even when the image can be preserved for a long time under high temperature and high humidity environments after printing. <P>SOLUTION: This recording medium has a recording layer, formed on a support, which contains a polymer with a quaternary ammonium salt derived from a cyclic amine in a molecule. The polymer having the quaternary ammonium salt derived from the cyclic amine in the molecule, preferably exists in the recording layer, in a particulate shape with 0.01 to 0.5 μm particle diameter. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
