摘要：
Provided is an inkjet recording medium in which hydrated alumina and a sulfinic acid compound or thiosulfonic acid compound coexist in a pigment in an ink receiving layer, and which can prevent white-background yellowing during storage in a resin file holder or the like and ensure printing quality at the same time. The ink receiving layer of the inkjet recording medium contains the sulfinic acid compound or thiosulfonic acid compound, which functions to prevent yellowing, in a salt form or in a free form so as to be diffusible.
