| Abstract | There is disclosed an improvement to the process for the de-inking of printed waste paper which comprises (1) treating the waste paper in a pulper at an alkaline pH with alkali silicate, an oxidatively active bleaching agent, one or more acid components selected from the group consisting of fatty acids and resinic acids containing more than 10 carbon atoms, and mixtures thereof, and a dispersing agent, and (2) separating the detached printing ink particles from the fiber suspension by either flotation, washing, or a combination thereof. The improvement comprises employing the acid and the dispersing agent in the form of an oil-in-water emulsion. |
