Provided are processes of applying a decorative imaging to a substrate that includes providing a stamp pad comprising a child and environmentally friendly disperse dye composition, inking a stamp with the disperse dye composition, optionally transferring the disperse dye composition from the stamp to an intermediate ink receptive surface using the rubber stamp to thereby place an image on an intermediate ink receptive surface, and transferring the image to a dye receptive object by application of sufficient heat and pressure. The disperse dye compositions provided herein are safe, environmentally friendly, and able to be used in stamp pad imaging processes.

An ink mixture is manufactured by mixing carbon, graphite, and solvents in a mixing system which may include a Cowles disperser. The conductive portions (e.g. carbon, graphite) are evenly and universally dispersed, because an even dispersal means the conductivity of the resulting conductive strip (electrode) will be even, consistent, and reliable. The various embodiments of the ink mixture comprise a blend of different conductive pigments, including but not limited to carbon black and graphite. These embodiments must be grinded until below 6.5 Microns in particle size.

An object of the invention is to provide a yellow ink composition for nonaqueous inkjet that achieves excellent density and weather resistance on printed matters whose printing surface is constituted by a polyvinyl chloride polymer, ethylene-vinyl acetate copolymer, or other vinyl polymer or the like, while also ensuring excellent discharge stability, even in a high-speed printing mode. To this end, a yellow ink composition for nonaqueous inkjet is provided that contains, as the pigment, C. I. Pigment Yellow 150 and C. I. Pigment Yellow 83 at a ratio by mass, calculated by C. I. Pigment Yellow 150/C. I. Pigment Yellow 83, of 5/5 to 9/1, and further contains a pigment dispersant, a resin, and an organic solvent.
