  • Aqueous dye preparations of dyes difficultly soluble in water
    Patent number: 4281999
    Abstract: The invention relates to novel aqueous dye preparations of dyes difficultly soluble in water, to processes for producing these dye preparations, to the use thereof for preparing printing pastes, and to the use of the said dye preparations for printing carrier materials for transfer printing, for printing in particular textile materials, or for dyeing textile materials, and also to the printed carrier materials, and to the material printed by means of these dye preparations in the transfer-printing process, or to the material dyed or printed in the dyeing or printing process. The novel dye preparations contain water, a finely dispersed dye of which the solubility in boiling perchloroethylene is lower than 0.5 g/kg, an anionic and/or nonionic dispersing agent, a resin which has affinity for the dye and which is more soluble than the dye in a solvent having limited miscibility with water, and optionally further additives.
