Abstract
This invention relates to new salts of organic polyisocyanates containing at least one isocyanurate ring carrying a negative charge and at least one non-metal ion having a positive charge, these new salts being organic salts of mono- or polyisocyanurates containing at least two free isocyanate functions. The new organic salts according to this invention may be represented by the following general formula (I) ##STR1## in which R is a bivalent aliphatic, cycloaliphatic, aromatic or heterocyclic radical which may be substituted, Q is an onium cation substituted by four identical or different radicals which may be aliphatic, cycloaliphatic, aromatic or heterocyclic possibly substituted radicals, a is the average number of molecular isocyanurate rings which may be equal to zero or to more than zero, b is the number of tetrasubstituted heteroatoms of Q which is of at least 1 and n is the average number of ionic isocyanurate rings which is of at least 1.
