The difficulties encountered in the manufacture of paper, cardboard, and other cellulosic articles, as they are caused by the formation of resinous or pitch deposits on the paper as well as on the paper machines and processing apparatus, are overcome, or at least considerably reduced, by the addition of phosphonic acids and more particularly of alkyl, amino or hydroxy alkyl, or cycloalkyl phosphonic acids or their alkali metal salts. If required, amino polycarboxylic acids, hydroxy carboxylic acids, or their alkali metal salts, or alkali metal polyphosphates are also added during processing.
