Abstract
Wood-containing DIP is an increasingly important raw material for manu facturing of graphic papers. An improved optical profile would offer a dditional options for the utilization of DIP in high-quality graphic p aper grades. Extensive bleaching trials with alternative chlorine-free bleaching agents (ozone, oxygen) make evident that for bleaching of w ood-containing DIP no benefit is obtained compared to conventional ble aching chemicals (peroxide, dithionite, FAS). This is valid in the cas e oi separate bleaching stages as well as of different bleaching seque nces.
