ABSTRACT:
Provided are novel yellow azo dyes which are useful in ink compositions, especially ink jet compositions. The dyes and ink compositions of the present invention exhibit a good balance of optical density, print reliability, water fastness and light fashion and exhibit improved water solubility, thus rendering the ink compositions to be especially suitable for printheads having small nozzle openings.
