ABSTRACT:
Solution inks have been discovered that have an acceptable red fluorescent signal for machine detection while emitting a different visual color in white light. The formulation is based on a combination of a fluorescent dyes and a non red dye belonging to the spectral sensitizer class of dyes. The red fluorescent dye and non-red dye are combined in a resin to form a toner. Because of a bathochronic shift, fluorescence at higher wave lengths is achieved. Upon dissolving the toner in a polar solvent, increased viscosity is achieved which results in an enhanced fluorescent signal as compared to prior fluorescent inks.
