摘要：
The invention relates to aqueous dispersions of alkaline earth metal soaps and/or alkaline earth metal resin soaps for deinking printed wastepaper in which the dispersions containA. alkaline earth metal salts of C.sub.6-22 carboxylic acids and/or resinic acids andB. C.sub.6.22 oxoalcohols alkoxylated with 2 to less than 6 mol C.sub.2-4 alkylene oxides and alkali metal and/or alkaline earth metal alumimo silicates corresponding to general formula I 0.7-1.5 cat.sub.2/n O.Al.sub.2 O.sub.3.0.8-6 SiO.sub.2in which cat represents alkali metal and/or alkaline earth metal cations and n is the valency of the alkali metal and/or alkaline earth metal cations.
