Fujifilm’s New US RxD Dispersion Facility is Key to Growth in Aqueous Inkjet Ink Market

The digital printing segment is growing rapidly. Much of that growth is centered on water-based inkjet printing, particularly in the textile, packaging and commercial print markets. The environmental benefits of digital printing, particularly aqueous inkjet printing, are considerable.

With that in mind, Fujifilm developed RxD pigment dispersions using a unique reactive dispersant cross-linking technology. Compared to dyes, pigments provide better fastness and similarly vibrant colors for printing, but they must be dispersed to prevent the particles sticking together.

Fujifilm’s RxD technology locks each pigment particle in a secure cage of cross-linked polymer, creating a highly stable dispersion. This means that a chemist can use a very wide range of components in their ink formulation, to achieve the functionality and performance demanded of the application and printhead.

RxD dispersions are used in inks that Fujifilm supplies to its inkjet OEM customers, and other ink formulators can also buy RxD directly from Fujifilm. They are manufactured at
