Abstract
Starch(es) and starch derivatives are combined together with at least one high-viscosity cellulose as a thickener in dispersion binder-based color systems. The cellulose has a viscosity of >50,000 mPa·s, measured by the Brookfield rotation viscometer as a 2% swollen aqueous solution at 5 rpm and 25° C. A method produces dispersion binder-based color systems and a dispersion color thickener combination and a dispersion color containing the dispersion color thickener combination.
