ABSTRACT:
Fluorescent Ink formulations have been conceived that result in inks having improved tack and flow properties so that problems relating to ink plugging with contemporary ink pads are reduced. Another advantage to the inks is that they have improved paper dust resistance, shelf life and flow properties. These inks are made of a coloring material having an organic non fluorescent pigment dispersed in a rosin ester and a solid solution of a fluorescent dye in triazine paraformaldehyde aryl sulfonamide resin dispersed in an alkyd resin. The solvent system is preferably composed of non drying solvents such as emollients and higher molecular weight glycols.
