Formulating tools for high performance digital printing Digital printing is a fast growing industry with specific requirements for innovative products. BASF offers a complete range of high quality raw materials for digital inks. Our comprehensive range of color organic pigments, dyes, pigment preparations, and styrene acrylic resins create vivid, long-lasting colors. We also offer a broad portfolio of photoinitiators, reactive diluents, and oligomers for energy curing. In addition, our additives, flow and slip agents, defoamers, and high molecular weight dispersants increase long-term rheological stability of solvent-based, water-based, and energy curable digital ink formulations. Plus our UV absorbers, light stabilizers, and antioxidants for inks and overprint varnishes help prints last longer. At BASF, we want to be your supplier of choice for the digital printing industry. For specific formulation requirements or a complete list of products, please contact your BASF representative. 3

Pigments for solvent-based and UV curable ink jet inks Cinquasia, Cromophtal, Heliogen, Irgalite, Irgazin, and Paliotol Coloristic performance is a key parameter when selecting a pigment for solvent and energy 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 and energy 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 list 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 and UV curable ink jet inks Microlith K Microlith Jet Microlith K BASF s Microlith K pigment preparations are state-ofthe-art pigment preparations (high performance pigments pre-dispersed in a vinyl copolymer) that are widely used in solvent-based ink jet 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 standard ink jet ink solvents like ketones, glycol ethers, or glycol ether esters (or blends thereof) by means of a dissolver or other high-speed mixers without the need for milling.

Microlith Jet Microlith Magenta 4500 J and Microlith Yellow 1061 J are the first in a series of innovative, high performance pigment preparations developed specifically for solventborne and especially UV ink jet applications. Similarly to customary Microlith K, Microlith J types excel by their small particle size and narrow size distribution, which is guaranteed by our specialized manufacturing process. Accurate particle size control allows maximum color strength and transparency as well as excellent dispersion stability. Microlith J types display high pigment load and can be easily incorporated in solventborne or acrylatebased UV curable systems by means of a dissolver or other high-shear mixers.

Photoinitiators for energy curing Darocur, Irgacure, and Lucirin The photoinitiator is 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 overprint varnishes. Energy curable inks and overprint varnishes provide excellent spectral sensitivity and the highest cure speed even at high pigment loadings at a low energy dose. Additional benefits include excellent solubility in acrylate monomers, low yellowing, and low odor/low migration properties.

Additives Irgastab in-can stabilizer Irganox antioxidant 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, such as Irgastab UV 22, against premature polymerization is necessary to provide long-term stability of the energy curable ink formulation during its life cycle. In addition, the antioxidant Irganox 1520 L 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. Product Chemistry Details Irgastab UV 22 Hindered phenol 14% solution in GPTA, inhibits early polymerization in UV inks and coatings Igranox 1520 L Hindered phenol Multifunctional, liquid phenolic antioxidant 17

UV absorbers and hindered amine light stabilizers Tinuvin Digitally printed signs and graphics are sometimes over-lacquered with an overprint varnish to improve the weatherability. BASF offers a broad selection of UV absorbers that can easily be incorporated into waterbased, solvent-based, or energy curable overprint varnish formulations. Due to broad spectral coverage and very high extinction, our UV absorbers provide excellent performance and photostability 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. Product Chemistry Details Tinuvin 123 Hindered amine light stabilizer (HALS) Aminoether HALS that minimizes defects such as cracking and gloss reduction Tinuvin 123-DW Hindered amine light stabilizer (HALS) Non-basic, non-interacting encapsulated HALS for zero/low VOC water-based formulations Tinuvin 292 Tinuvin 171 Tinuvin 384-2 Tinuvin 928 Tinuvin 400-DW Tinuvin 460 Tinuvin 479 Hindered amine light stabilizer (HALS) Hydroxyphenyl-benzotriazole Hydroxyphenyl-benzotriazole Hydroxyphenyl-benzotriazole Hydroxyphenyl-triazine Hydroxyphenyl-triazine Hydroxyphenyl-triazine HALS that provides significantly extended lifetime to coatings by minimizing defects such as cracking and loss of gloss UV absorber suitable for photographic applications where initial yellowing must be kept to a minimum UV absorber with a high thermal stability and environmental permanence suitable for coatings exposed to high bake cycles and/or extreme environmental conditions UV absorber that provides excellent solubility, high thermal and environmental permanence for high performance coating applications and light sensitive substrates Encapsulated UV absorber with high extinction in the UVB range for high performance applications and/or zero to low VOC water-based formulations UV absorber that provides outstanding protection to coatings and light sensitive substrates UV absorber that provides excellent performance in thin film applications and very high photostability 18
