Pigments for solvent-based and UV-curable inkjet inks Cinquasia®, Cromophtal®, Heliogen®, Irgalite®, Irgazin® and Paliotol®

Coloristic performance is a key parameter when selecting a pigment for solvent-based and UV-curable ink formulations. Although other factors should be taken into account, our high-performance organic pigments have been found to be particularly suitable for use in solvent-based and UV-curable digital inks. These pigments combine outstanding tinctorial properties with excellent rheology in acrylate systems and offer outstanding resistance to light, weather, heat, chemicals and solvents.

Although this brochure represents the primary selections, BASF offers additional colorants, which cover a wide range of chemical types, shades and fastness performance. For a complete list, please contact your BASF representative.

Pigment preparations for solvent-based inkjet inks Microlith® K/KJ

In addition to our line of powder pigments, BASF’s Microlith® K pigment preparations are state-of-the-art pigment preparations (high-performance pigments pre-dispersed in a vinyl copolymer) that are widely used in solvent-based inkjet inks for wide-format indoor and outdoor graphics. Their small particle size and extremely narrow particle size distribution, obtained by our specialized milling technology, affords maximum color strength and transparency as well as outstanding dispersion stability.

Microlith® K pigment preparations are easily incorporated into usual inkjet ink solvents such as ketones, glycol ethers or glycol ether esters (or blends thereof) by means of just a dissolver or other high-speed mixers, without the need for milling.

Pigment preparations for UV-curable inkjet inks Microlith® J

Microlith® J is a new generation of high-performance pigment preparations specifically developed for UV-curable inkjet inks. It consists of high-grade organic pigments and carbon black, pre-dispersed in an acrylic co-polymer binder. Microlith® J preparations excel by their small particle size and narrow particle size distribution, which is guaranteed by our specialized manufacturing process. Accurate particle size control allows maximum color strength, gloss and transparency as well as excellent dispersion stability. Microlith® J can be easily

incorporated into commonly used acrylate- or vinyl-based inkjet monomers by means of just a dissolver or other high-shear mixers without the need for milling. Further, Microlith® J can also be used for the straightforward formulation of ultra-low viscosity solvent-based inkjet inks.

applies highly recommended potentially suitable use as co-initiator

Energy-curable inks and varnishes require excellent spectral sensitivity and the highest cure speed even at high pigment loadings and at low energy dose. The photoinitiator is therefore a key component of an energy-curable formulation, as it largely determines the spectral sensitivity and cure response of the system.

BASF offers a broad range of highly effective photoinitiators for energy-curable inks and varnishes with a range of additional benefits including excellent solubility in acrylate monomers, low yellowing, low odor and low migration properties. BASF also offers photoinitiators for cationic curing processes.

Additives Irgastab®

Energy-curable formulations containing acrylate reactive diluents and oligomers, photoinitiators and pigments are sensitive to early polymerization during storage. This is particularly true for highly reactive systems based on multifunctional acrylates, as used in printing applications. Therefore, the addition of an efficient stabilizer against premature polymerization is necessary to provide long-term stability of the energy-curable ink formulation during its life cycle.

In addition, an antioxidant can be added directly into the ink formulation to protect the colorant and binder against photo-oxidation, which will also help increase the lifetime of the digitally printed image.

Irgastab® UV 25 hindered phenol 14 % active matter in phenoxyethyl acrylate, efficiently inhibiting premature thermal polymerization of UV inkjet inks and providing long shelf life

UV absorbers and hindered amine light stabilizers Tinuvin®

Digitally printed signs and graphics are sometimes over-lacquered with an overprint varnish to improve weatherability. BASF offers a broad selection of UV absorbers that can easily be incorporated into water-based, solvent-based, or energy-curable overprint varnish formulations. Due to broad spectral coverage and very high extinction, our UV absorbers provide excellent performance and photo-stability by filtering harmful UV light and protecting the underlying image against fading.

In addition, the overprint varnish itself can be protected against light degradation (cracking, loss of gloss, delamination, etc.) by the addition of hindered amine light stabilizers (HALS) in coating formulations. Alternatively, they can be added directly into the ink formulation to help protect the colorant and binder against photo-oxidation, which will also increase the lifetime of the digitally printed image.

Products Chemistry Details

Tinuvin® 460 hydroxyphenyl triazine UV absorber that provides outstanding protection to coatings and light-sensitive substrates

Tinuvin® 479 hydroxyphenyl triazine UV absorber that provides excellent performance in thin-film applications and very high photo stability

Tinuvin® 171 hydroxyphenyl benzotriazole UV absorber suitable for photographic applications where initial yellowing should be kept to a minimum

Tinuvin® 384-2 hydroxyphenyl benzotriazole

UV absorber with high thermal stability and environmental permanence suitable for coatings exposed to high bake cycles and/or extreme environmental conditions

Tinuvin® 928 hydroxyphenyl benzotriazole

UV absorber that provides excellent solubility, high thermal and environmental permanence for high-performance coating applications and light-sensitive substrates

Tinuvin® 123 hindered amine light stabilizer (HALS) aminoether HALS that minimizes defects such as cracking and gloss reduction
