| Résumé : |
Over the past decade environmental and health considerations have resulted in the development of inks with lower volatile organic compound (VOC) content. Novel waterborne self-crosslinking and storage stable polymers for environmentally friendly printing inks and overprint varnishes have been developed by Akzo Nobel Resins. These polymers, which are supplied as waterborne acrylic emulsions, form crosslinked films upon drying at ambient temperatures. The acrylic emulsions are based on proprietary keto-functional polymers that can be conveniently made via multi-stage emulsions polymerization. They are especially useful in applications onto non-absorbing substrates (NAS), where they offer fast dry combined with good adhesion, gloss, solvent resistance, cold and hot water resistance and resolubility. Completely solvent-free ink formulations based on AD1, AD2 EPD and grinding resin ADG are given. Key properties of the printing inks are discussed and compared with other waterborne and solventborne printing inks. |
