Abstract

The invention relates to a process for the production of solutions of substantially water-insoluble complex antimony compounds in polar organic solvents by esterifying an .alpha.-hydroxy polycarboxylic acid with a polyol, reacting an excess of the esterification product with an antimony oxide in a polar organic solvent and reacting the free carboxylic groups with a monoisocyanate.
