ABSTRACT:
An article has a constitution such that yellowing (e.g., yellowing of white portions upon storage in a resin file or the like) of the article can be continuously prevented over a long period of time even when it has a porous site composed of a pigment, such as an alumina hydrate, in an ink-receiving layer. An article, an ink recording medium and an ink-jet recording medium comprising a phenolic compound having a sulfonyl group and a diffusible sulfinic acid salt, and a production process of the ink-jet recording medium are provided.
