Abstract: Process for de-inking printed papers by soaking the papers in an aqueous medium in the presence of water-soluble or water-dispersible polymeric amphiphile compounds in which the hydrophilic and hydrophobic parts consist of condensed and/or polymerised monomer units and alkali and, where applicable, further customary de-inking aids, followed by cleaning the waste paper by washing or flotation.

Abstract: Insecticidal agents containing insecticidal active ingredients selected from the group consisting of carbamates, phosphoric (phosphonic) (di)(thio) acid esters, pyrethrins, pyrethroids, alpha -alkylphenyl acetates, alpha -cyclopropyl-phenyl acetates and chlorinated hydrocarbons, and, to increase the insecticidal action of these active ingredients, triazole derivatives or salts thereof. The triazole derivatives have the formula I, where R denotes unsubstituted or halogen-substituted phenyl, or Y denoting hydrogen, halogen, alkylmercapto of 1 to 6 carbon atoms, alkenylmercapto of 2 to 6 carbon atoms, or unsubstituted or halogen-substituted phenylmercapto, X denoting halogen, and n denoting one of the integers zero, 1 and 2, with the proviso that n does not denote zero when Y is halogen.

Abstract: A process is disclosed for producing paper with a dry-strength and wet-strength finish by adding to the paper pulp combinations of hydrophilically modified polyisocyanates and polymers containing vinyl amine units, then by dewatering the paper pulp to form sheets of paper, or by treating the paper surface with hydrophilically modified polyisocyanates and polymers containing vinyl amine units. Also disclosed is the use of said combinations of polyisocyanates and polymers as dry-strengthening and wet-strengthening agents of hygienic and kraft papers.
