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):
wherein X1, X2 and X3: a hydrogen atom, an alkyl group, an alkoxy group, or an aryloxy group; R1: a hydrogen atom or an alkyl group having 1 to 4 carbon atoms; R2, R3 and R4: a hydrogen atom, or an alkyl group having 1 to 18 carbon atoms, an aryl group or an aralkyl group; Z: -O- or -NH-; Y2: 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.
