Abstract:
Process for dyeing textile fiber materials of polyacrylonitrile or copolymers of acrylonitrile with cationic dyestuffs which comprises carrying out the dyeing in the presence of amidinium compounds of the formula
WHEREIN R1, R2, R3, R4 and R5 are, independently of one another, hydrogen, an optionally substituted alkyl, cycloakyl, aralkyl or aryl group; R2 may form with R1 or R3 and/or R4 with R5 a heterocyclic ring, and X is an anion.
