Flexographic printing ink modified with hyperbranched polymers: Boltorn P500 and Boltorn P1000
Abstract
$The flexographic printing ink Urania was modified with commercially available hyperbranched polymers,Boltorn P500 and Boltorn P1000. The surface tension of the printing inks was measured andthe rheology behaviour of pure polymers and printing inks is presented. The obtained flow curves (shearstress versus shear rate) for printing inks exhibited pseudoplastic behaviour. Modified flexographic inkswere laboratory printed on three different plastic films: PE, oPP and PET. The impact of a small amount ofhyperbranched polymers on printing ink colour was examined by optical density, total colour differenceDE (L*, a*, b*, CIE) and the gloss of the print film. In general, the addition of hyperbranched polymersimproved the colour properties of the overprinted sample and colour fastness to rubbing. The influenceof hyperbranched polymers on the rheological properties, optical density and L*, a*, b* coordinates andcolour fastness is discussed.
