    摘要： A water-based ink containing a water-soluble dimer coloring material having a molecular structure having two chromophores and being symmetrical via a decomposable linking group, a water-soluble monomer coloring material having the same structure as the molecular structure obtained by the decomposition of the linking group in the water-soluble dimer coloring material, and a first water-soluble organic solvent which is a triol compound being liquid at normal temperature and having less than 5 carbon atoms, capable of restraining the water-soluble dimer coloring material from being decomposed. The water-soluble monomer coloring material is from 1% or more to 12% or less in weight with respect to the weight of the water-soluble dimer coloring material. Also disclosed are an ink tank holding therein this ink, and an ink-jet recording process carried out using this ink.
