The present invention relates to storage-stable dye salts, solutions and compositions thereof a process for their preparation and their use for dyeing and/or printing substrates.

The present disclosure concerns the design, formulations, preparations and optical properties of compounds of Formulas (I) and (VI):
(charged dye.sup.m+).sub.x.Math.(counterion.sup.n).sub.y.Math.(counterion receptor).sub.z(I) and
(charged dye.sup.m).sub.x.Math.(counterion.sup.n+).sub.y.Math.(counterion receptor).sub.z(VI). The charged dye.sup.m+ is a cationic dye, counterion.sup.n is an anion, and counterion receptor is a binding ligand for the counterion.sup.n, wherein m, n, x and y are integers greater than or equal to 1, and products of x.Math.n and m.Math.y are identical for formula (I). The charged dye.sup.m is a anionic dye, counterion.sup.n+ is a cation, and counterion receptor is a binding ligand for the counterion.sup.n+, wherein m, n, x and y are integers greater than or equal to 1, and products of x.Math.n and m.Math.y are identical for formula (VI).
