Abstract
For the Contracting States : BE, DE, FR, GB, IT, SE 1. Dispersions of dinitroanthraquinones for use in processes for the production of pulp, characterized in that they contain the dinitroanthraquinones, in finely divided form, surface-active agents and water and/or liquid organic compounds with boiling points above 80 degrees C. For the Contracting State : AT 1. Process for the preparation of dispersions of dinitroanthraquinones for use in processes for the production of pulp, characterized in that dinitroanthraquinones, surface-active agents and water and/or liquid organic water-miscible compounds with boiling points above 80 degrees C are group with one another.
