Title: Transfer printing on textile material

Abstract: Transfer printing process on textile material is described with the use of a printing ink having an organic-aqueous base, which printing ink contains, in addition to at least one binding agent, at least one organic solvent and, optionally, water, an aqueous preparation of transferable dyestuffs or optical brighteners that are insoluble to difficultly soluble in water and have a particle size of less than 10.mu., which preparation has a low content of dispersing agent and a high concentration of dyestuff or of optical brightener, characterized in that this preparation contains at least 10 percent by weight of water, at least 30 percent by weight of a finely dispersed transferable dyestuff or optical brightener insoluble to difficultly soluble in water, and a mixture consisting of at most 10 percent by weight of an anion-active dispersing agent, at most 5 percent by weight of a nonionic dispersing agent, and at most 35 percent by weight of a hydrotropic agent, as well as, optionally, further additives.
