<p>An additive which can improve the water resistance of a water-soluble dye with which an article has been dyed; and an ink-jet recording medium which contains the additive, is excellent in the water resistance and resolution of characters or images recorded thereon, and is suitable for multicolor recording. The additive is obtained by reacting a secondary amine, ammonia, an epihalohydrin, and a crosslinking agent as essential ingredients. The recording medium is obtained by causing the additive to be present on a surface and/or inner part of a base.</p> |
