Abstract: Increasing the electrostatic charge capacity of powder lacquers or powder for surface coating of solid objects is effected by incorporating ca. 0.01-10 (wt.)% of saline, cationic cpds(s). (I) homogenously, so that (I) are dissolved or dispersed in the powder lacquer system or powder, (I) having the formula: R1-4 independently =H, linear or branched 1-30C alkyl, mono- or polynuclear 5-12C cycloaliphatic gps., oxyethyl gps. of the formula -CH2-CH2-O)n-R (with n=1-10 and R=H, 1-4C alkyl or acyl), mono- or polynuclear aromatic or araliphatic gps., in which the aliphatic, aromatic and araliphatic gps. can be substd. by OH, 1-4C alkoxy, sec. or tert. amino, acid amide and/or acid imide gps. and the alkyl, cycloalkyl, aralkyl and aryl gps. for R1-4 can be substd. by F, Cl or Br; X=P, As or Sb and if X=As or Sb, at least one of R1-4 not=H; A(-)=the equiv. of an (in)organic anion. More specifically R1-4=1-22C alkyl, phenyl, benzyl and/or -(CH2-CH2-O)n-R (with n=1-10 and R=H, 1-4C alkyl or acyl); A(-)= Cl, Br, SO4, HSO4, OH, BF4, PF6, NCS, ClO4, AsF6, meta- or ortho-phosphate, molybdate, tungstate, phosphomolybdate, the equiv. of an anion of a P, Mo, W or Si iso- or heteropolyacid, a phosphonic acid or phenol- or napthol-carboxylic or -sulphonic acid.
