Fujifilm has expanded its series of high-performance RxD pigment dispersions for water-based inkjet ink formulation to include Orange PO71, Green PG7, and Violet PV23 pigments. 

OGV colours are typically used to formulate ink sets that extend the gamut of a print system beyond the colour space achievable with CMYK, which is particularly important for achieving higher vibrancy, colour accuracy and matching brand spot colours in packaging, textile and commercial print applications. 

Grant Murney, product manager of RxD inkjet pigment dispersions, said: “In developing the new RxD Orange, Green and Violet dispersions, we’ve carefully selected the best polymers and processing conditions to ensure optimum stability and print performance for our customers in line with the standard CMYK products already in the RxD product range.” 

RxD pigment dispersions are used in Fujifilm’s aqueous ink developments for OEMs and are available to other ink formulators. 

According to Fujifilm, RxD dispersions are highly stable and suitable for ink formulation across a wide range of applications. They are engineered with Fujifilm’s proprietary reactive dispersant technology, which uses a cross-linked polymer to create a secure cage around the pigment. This provides a stable dispersion that is compatible with a wide range of components used in inkjet ink formulation, enabling the design of stable ink formulations that meet demanding performance requirements. 

The pigments used in RxD dispersions comply with Swiss Ordinance SR817.023.21, making indirect food contact-compliant applications accessible.

Last year, Fujifilm announced a further expansion with a USD 47 million investment in its global RxD inkjet dispersion manufacturing capabilities, part of its commitment to meet the growing demand for new applications with aqueous inkjet inks.
