Abstract

The invention relates to mononoble metal dithiolates, more particularly water-soluble monogold(I) dithiolates, to their production and to their use for the production of noblemetal-containing decorations on firing-resistant substrates. The mononoble metal dithiolates represent a new class of water-soluble thiolates for use in organic-aqueous and essentially purely aqueous noble metal preparations for decoration purposes. The mononoble metal dithiolates correspond to the following formula: ##STR1## in which Em=Au(I), Ag(I), an equivalent of Pd(II), Pt(II) or Rh(III), Q=a tetravalent organic radical containing 2 to 10 carbon atoms, Y=a hydrophilic group from the series comprising --COOH, --COO.sup.-cat.sup.+ or --COO--(CHR.sup.1 --CHR.sup.2 --O).sub.m R.sup.3 Z=Y or H or a group from the series comprising --OR', --SR', --SO.sub.3 R', --NR'.sub.2, --NR.sub.3.sup.+ X.sup.-.
