Fluorescent water-base ink for ink-jet recording

A fluorescent water base ink for ink-jet recording, comprising:

• water;
• and
• a fluorescent dye consisting of a first fluorescent dye and a second fluorescent dye;
• wherein:
• the first fluorescent dye has a first absorption spectrum and a first fluorescence spectrum;
• the second fluorescent dye has a second absorption spectrum and a second fluorescence spectrum;
• the first absorption spectrum comprises a first ultraviolet absorption wavelength region and an additional absorption wavelength region;
• the first fluorescence spectrum comprises a first fluorescence emission wavelength region;
• the second absorption spectrum comprises a second ultraviolet absorption wavelength region;
• the second fluorescence spectrum comprises a second fluorescence emission wavelength region;
• the first ultraviolet absorption wavelength region is different from the second ultraviolet absorption wavelength region;
• and
• the additional absorption wavelength region overlaps at least a part of the second fluorescence emission wavelength region.
