Abstract
Object of the present invention are novel printing inks with organic solvents for sublimation transfer printing which contain a high concentration of very finely dispersed, transferable cationic dyes, and specifically; PA1 A. at least one cationic dye or a mixture of cationic dyes, PA1 B. at least one soluble resin as stabilizer, film former and thickener, PA1 C. a low-viscosity, low molecular organic solvent or solvent mixture in which the cationic dye or dyes are only slightly soluble at room temperature and the resin or resins are at least 5% soluble, PA1 D. an inorganic or organic acid acceptor or mixtures thereof, and PA1 E. at least one indicator dye which is inert to inorganic or organic acid acceptors.
