    • A fluorescent water base ink for ink-jet recording contains a fluorescent dye having a xanthene skeleton, and a glycol. In the fluorescent dye, the difference in hydrophilic index log P is not less than 2.6 between a substituent bonded to C-9 carbon atom of the xanthene skeleton and other portion of the fluorescent dye than the substituent bonded to the C-9 carbon atom. The glycol has a distance between hydroxyl groups substantially equivalent to or longer than an interatomic distance between atoms directly bonded to C-3 and C-6 carbon atoms of the xanthene skeleton of the fluorescent dye, respectively. It is assumed that the glycol is coordinated with the xanthene skeleton in a bridge form to increase the fluorescence intensity by increasing the electron density of the xanthene skeleton. The ink having high fluorescence intensity and in which the fluorescence intensity is not lowered in a time-dependent manner is provided.
    • 用于喷墨记录的荧光水基油墨包含具有呫吨骨架的荧光染料和二醇。 在荧光染料中,与结合到C-9碳原子的取代基相比,在呫吨骨架的C-9碳原子的取代基和荧光染料的其它部分之间,亲水指数log P的差异不小于2.6。 乙二醇的荧光染料的呫吨骨架的直接与C-3和C-6碳原子直接键合的原子之间的原子间距离基本上等于或大于等于或更长的羟基之间的距离。 假设二元醇以桥形式与呫吨骨架配位,通过增加呫吨骨架的电子密度来提高荧光强度。 提供了具有高荧光强度且荧光强度不以时间依赖性降低的油墨。
