Mixtures of organic ammonium salts composed of 20 to 80% of a quaternary ammonium salt of the formula <IMAGE> and 80 to 20% by weight of an amine salt of the formula <IMAGE> where in both formulae R1 denotes C12-C26-alkyl, C12-C26-alkenyl, C12-C26-fluoroalkyl, C12-C26-fluoroalkenyl or a group of the formula <IMAGE> <IMAGE> or Rf(CH2)yB(CH2)x, R2 and R3 denote C1-C3-alkyl, preferably methyl, R4 denotes C1-C4-alkyl and, for the case where R1=alkyl or alkenyl, also a group of the formula -(C2H4O)zH, Rf denotes C8-C20-fluoroalkyl or C8-C20-fluoroalkenyl, R5 denotes hydrogen, methyl or ethyl, B denotes oxygen or sulfur, x denotes an integer from 2 to 6, 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.
