FLUORESCENT PIGMENT INK COMPOSITION THAT IS USEFUL IN BUBBLEJET INK JET PRINTER

摘要

An ink composition especially suited for ink jet printers that use bubble jet technology. The ink compositions contain pigments obtained by emulsion polymerization of sub-micron size particles dispersed in water. Either fluorescent or non-fluorescent dyes can be added to the pigments. Coalescing agents, or humectants, are added to the ink formulations to improve the film forming properties as well as prevent premature drying. Surfactants are added for dispersion stabilization.
