Abstract: In a dry heat process for dyeing and printing of organic material which can be dyed with cationic dyestuffs, the improvement wherein at least one transferable salt of a cationic dyestuff with an acid having a pK.sub.s value greater than 3 is used for dyeing and printing.

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;A. at least one cationic dye or a mixture of cationic dyes,B. at least one soluble resin as stabilizer, film former and thickener,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,D. an inorganic or organic acid acceptor or mixtures thereof, andE. at least one indicator dye which is inert to inorganic or organic acid acceptors.

Abstract: A process for dyeing and printing blends of wool and polyacrylic fibers which comprises the use of dyes of the formula ##STR1## wherein A is the radical of a monofunctional or polyfunctional tertiary amine, X is an anion and F is the radical of a dye of the disperse class.
