Pigment Dispersions for UV and UV LED Digital Inks


KP-UV series are pigment dispersions at high pigment loads (30 wt.%) specifically designed for the production of UV and UV LED digital inks.

They are based on high-performance resin-free polymeric dispersants, inkjet quality pigments and a blend of two key monomers, DPGDA and PONPGDA. Their excellent long-term stability, color strength and compatibility with most monomers and oligomers assure both reliability and flexibility to ink formulators.

KP-UV series pigment dispersions can be mixed with the letdown solution in various quantities depending on individual formulations and custom applications.

With KP-UV series is possible to produce a finished digital ink without having to carry out additional process steps and with the following advantages:

- Speed to produce the ink: it will allow user to strongly reduce production, transport and research costs.

- High pigment concentration: they allow user to make an extremely easy formulation and to benefit from an important increase on production yield.


Main Characteristics:

• High pigment load (30 wt.%)

• Based on HMW dispersant

• Low viscosity

• « nm average particle size, narrow particle size distribution

• Excellent compatibility with a wide range of co-solvents and resins

• Excellent storage stability

• Possibility of providing tailor-made dispersions (process and spot colors)
