<p>Provided are a new cationic polymer and an inkjet recording sheet exhibiting a superior printing density of an image without lowering ink receptivity. (1) A cationic polymer represented by the following general formula (A): <CHEM> <CHEM> wherein X<1>, X<2> and X<3>: a hydrogen atom, an alkyl group, an alkoxy group, or an aryloxy group; R<1>: a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R<2>, R<3> and R<4>: a hydrogen atom, or an alkyl group having 1 to 18 carbon atoms, an aryl group or an aralkyl group; Z: -O- or -NH-; Y<2>: a bivalent linking group having 1 to 8 carbon atoms, which may have therein a linking heteroatom; and x : an anion. (2) An inkjet recording sheet, that has, on a substrate, a colorant-accepting layer containing cationic polymer modified inorganic pigment particles.</p> |
