Definitions

• R represents an aliphatic hydrocarbon radical with at least eight carbon atoms
• R represents a lower alkyl radical
• R represents a lower alkyl radical optionally substituted by hydroxyl and/or phenyl groups
• R represents a lower alkylene bridge
• X- represents the anion equivalent of an acid usch as
• the aliphatic hydrocarbon radical R can be saturated or unsaturated, straight or branched. It has at least eight and preferably 12 to 14 carbon atoms. Examples for R are the octyl, decyl, dodecyl or myristyl radical.
• the alkylene bridge R preferably has at most three carbon atoms and represents especially the methylene group.
• Suitable as cationic dyestuffs applicable according to the invention are, advantageously, the technically easily accessible salts and metal halides, e.g., zinc chloride double salts of the known basic dyestuffs.
• These are, e.g., thiazines, oxazines, diphenyl methane, triphenyl methane, rhodamines, azoor anthra-quinone dyestuffs and preferably monoazo, methine and azomethine dyestuffs, all containing onium groups, whereby as onium groups reference is made, above all, to ammonium groups.
• fiber material consisting of polymeric and copolymeric acrylonitrile
• fiber materials are suitable, the fiber-forming substance of which consists of a synthetic, longchained polymer containing at least acrylonitrile.
• suitable groups are primarily carboxylic acid groups, carboxylic acid amide groups or hydroxyl groups, and also sulphonic acid groups.
• the temperature of the dye bath is raised to the boiling point and the dye bath is held at this temperature for 1 hour. After cooling to 60, the dyed material is taken out and then rinsed with lukewarm and cold water.
• Process for the production of level dyeings on polymeric or copolymeric acrylonitrile fibers,- said fibers containing at least 85% acrylonitrile, comprising dyeing this material withan acid dye liquor having a pH in the range between 3.5 to which contains at least one basic dyestufi and a quaternary ammonium co npoundof the formula 3.
