Abstract: 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.

Abstract: The object of the present invention is to provide a spark plug having a discharge portion formed of a noble-metal chip increased in the Ir content while reducing the content of expensive Rh, which can be restrained from generation of unusual wear in the form of eroding the circumferential side surface of the noble-metal chip and exhibits excellent wear resistance. In the present invention, the discharge portion (31) in the center electrode (3) side is formed of a noble-metal chip (31?) comprising an Ir-based alloy and the noble-metal chip (31?) contains 90% by weight or more of Ir as the main component and further contains 0.5% by weight or more of Rh and from 0.5 to 8% by weight of Ni, whereby the noble-metal chip (31?) [discharge portion (31)] can be ensured with good wear resistance, the generation of unusual wear which readily occurs on decreasing the Rh content can be prevented by the addition of Ni and in turn, a spark plug having high performance can be fabricated at a low cost.
