Fe3O4@SiO2–BF3 nanoparticles were prepared as a novel solid acid and effectively applied for the solvent-free synthesis of arylazo-1-naphthols at room temperature.
Inkjet ink compositions comprising a liquid vehicle, an azo pigment, and a synergist are described. The colorant of the azo pigment and the synergist have specific structural features that, in combination, can be used to form an inkjet ink composition having long term stability in a variety of ink vehicles.
