Abstract

Flow accelerating with mixtures of organic ammonium salts composed of 20 to 80% of a quaternary ammonium salt of the formula ##STR1## 80 to 20% by weight of an amine salt of the formula ##STR2## where in both formulae R.sup.1 denotes C.sub.12 -C.sub.26 -alkyl, C.sub.12 -C.sub.26 -alkenyl, C.sub.12 -C.sub.26 -fluoroalkyl, C.sub.12 -C.sub.26 -fluoroalkenyl or a group of the formula ##STR3## R.sub.f --(CH.sub.2).sub.y B(CH.sub.2).sub.x --, R.sup.2 and R.sup.3 denote C.sub.1 -C.sub.3 -alkyl, preferably methyl, R.sup.4 denotes C.sub.1 -C.sub.4 -alkyl and, for the case where R.sup.1 =alkyl or alkenyl, also a group of the formula --(C.sub.2 H.sub.4 O).sub.z H, PA1 R.sub.f denotes C.sub.8 -C.sub.20 -fluoroalkyl or C.sub.8 -C.sub.20 -fluoroalkenyl, PA1 R.sup.5 denotes hydrogen, methyl or ethyl, PA1 B denotes oxygen or sulfur, PA1 x denotes an integer from 2 to 6, PA1 y denotes 0, 1 or 2, and z denotes numbers from 1 to 4, and additionally 30-70 mole %, preferably 40-60 mole %, particularly preferably 50 mol %, of alkali-metal salicylate calculated on the basis of the total amount of .beta.-hydroxynaphthoic acid.
