Abstract
The invention relates to an ink-jet ink composition suitable for use in secondary transfer processes wherein the ink-jet ink composition contains a pre-dispersion containing at least a sublimation colorant combined with an ink-jet ink containing at least a non-sublimable colorant. Upon printing, a monochrome intermediate transfer substrate is created. From this monochrome substrate, a multi-color image can be transferred to a permanent substrate with the application of heat and pressure. The monochrome intermediate transfer image is created by the non-sublimable colorant upon printing. The multi-color permanent image is generated as elevated temperatures and pressure of the transfer process cause the sublimation colorant to sublime and bond to the permanent substrate.
