Abstract
The present invention is directed to an ink set of inks which have substantially identical light fastness properties. The ink set includes ink compositions containing a colorant and at least one colorant stabilizer. The colorant stabilizer imparts light-stability to the colorant so that the colorant does not fade when exposed to electromagnetic radiation such as sunlight or artificial light. The ink set provides a range of colored inks having similar light-stability.
