Procedure
An ink comprised of 7 percent by weight of Levanyl A-SF carbon black obtained from Bayer Corporation, 20 percent by weight of sulfolane (obtained from Bayer), 5 percent by weight of trimethylopropane, 0.1 percent by weight of triethanolamine, and 1.5 percent by weight of the emulsion obtained from Example V (34.3 percent by weight of poly(methyl methacrylate-butyl acrylate-acrylic acid) resin, 2.0 percent by weight of polyethoxylated stearyl ether nonionic surfactant Brij 700™, and 63.7 percent by weight of water) was prepared by the addition of sulfolane, trimethylopropane, triethanolamine and resin emulsion in water through simple agitation using a stir bar for about 15 minutes. The resulting mixture was added to a stirring solution of Levanyl A-SF carbon black. The ink mixture resulting was stirred with a stir bar for about 5 to about 10 minutes, and the resulting ink mixture was filtered through a 1 μm glass fiber filter. The resulting ink was comprised of 7 percent by weight of Levanyl A-SF carbon black, 20 percent by weight of sulfolane, 5 percent by weight of trimethylopropane, 0.1 percent by weight of triethanolamine, 1.5 percent by weight of nonionic surfactant Brij 770™ stabilized poly(methyl methacrylate-butyl acrylate-acrylic acid) resin emulsion, and 66.4 percent by weight of water.
