Colorant stabilizers |
摘要 |
The present invention is directed to compositions containing a colorant and at least one porphine. The present invention includes an ink set of one or more inks which have substantially identical light fastness properties. One or more of the inks of the ink set includes a colorant and at least one porphine. The porphine 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.
