Abstract: Gegenstand der vorliegenden Erfindung ist ein Verfahren zur Herstellung eines lagerstabilen Granulates bestehend im wesentlichen aus einem Bleichaktivator und einem anorganischen Bindematerial, gekennzeichnet durch die Verfahrensschritte:

a) Vermischen eines trockenen Bleichaktivators mit einem trockenen anorganischen Bindematerial,
b) Verpressen dieser Mischung zu größeren Agglomeraten und
c) Zerkleinern dieser Agglomerate auf die gewünschte Korngröße.

Weiterer Gegenstand der Erfindung ist die Verwendung, der nach diesen Verfahren hergestellten Granulate in Wasch-, Reinigungs-, Blech- und Desinfektionsmitteln.

Abstract: An agent for improving the printability of paper and board, essentially comprising 50 to 95% by weight of water, and 5 to 50% by weight of a mixture of I. 1 to 50% by weight of (a) an organic quaternary ammonium salt having at least one C8-C22-alkyl group, (b) a mixture of 50 to 99.5% by weight of an organic quaternary ammonium salt and 0.5 to 50% by weight of a saturated or unsaturated C8-C22 -fatty acid, an oxidized wax or a polyglycol having a molecular weight of greater than 4,000, or (c) a mixture of 50 to 99.5% by weight of an organic amine which has been partly neutralized using a mineral acid or a lower carboxylic acid, and 0.5 to 50% by weight of a saturated or unsaturated C8-C33-fatty acid, an oxidized wax or a polyglycol having a molecular weight of greater than 4,000, and II. 50 to 99% by weight of a water-soluble or water-swellable polymer containing anionic groups. In the case of printing papers which are treated with this agent preferably by coating, a reduction in strike-through and show-through of printing ink becomes especially apparent.
