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.
La présente invention concerne une composition d'encre d'impression jet d'encre convenant pour des traitements de transferts secondaires, et contenant une pré-dispersion combinant au moins un colorant sublimable à une encre d'impression jet d'encre contenant au moins un colorant non sublimable. Le processus d'impression crée un substrat intermédiaire monochrome de transfert. A partir de ce substrat, il est possible de transférer sur substrat permanent une image polychrome sous l'effet de la chaleur et d'une pression. L'image de transfert intermédiaire monochrome est créée à l'impression par le colorant non sublimable. L'image permanente polychrome résulte de la sublimation et de la fixation sur le substrat permanent du colorant sublimable sous l'effet des températures élevées et de la pression propres au processus de transfert.
