BASF has introduced Joncryl 633 emulsion polymer, a cost-effective ink vehicle that  improves opacity of inks and requires less titanium dioxide. Joncryl 633 emulsion polymer can help ink formulators achieve high levels of color intensity and opacity in inks used on natural kraft substrates, such as brown box corrugated containers and paper bags. Tests conducted in BASF laboratories with Joncryl 633 demonstrate higher opacity and better color performance than other standard opaque emulsion po...
