WHEREIN R1 and R2 independently of one another denote alkyl, cycloalkyl or aralkyl or conjointly form a cycloalkyl ring, R3 denotes hydrogen, alkyl, cycloalkyl, aryl or aralkyl, R4 denotes hydrogen, alkyl, nitrile, carbamoyl, N-alkylcarbamoyl, alkoxycarbonyl or aralakoxycarbonyl, A represents the remaining members of a dibenzofurane radical which is optionally substituted further, and X represents a nitrile, carboxylic acid ester or carboxylic acid amide group are suitable for dyeing and printing synthetic fibre materials.
ARE PREPARED WHICH ARE ADAPTED FOR USE IN DYEING AND PRINTING MATERIALS MADE OF LEATHER, TANNIN TREATED COTTON, CELLULOSE ACETATE, SYNTHETIC SUPER POLYAMIDES AND POLYURETHANES AND FOR THE DYEING OF LIGNIN-CONTAINING FIBERS AS WELL AS FOR USE IN PREPARING INK-TYPE MATERIALS. AS DYESTUFFS THE MATERIAL ARE CHARACTERIZED BY GOOD FASTNESS TO LIGHT, WET PROCESSING, RUBBING AND SUBLIMINATION, AND THEY ARE GENERALLY CHARACTERIZED BY GOOD AFFINITY TO THE SUBJECT FIBERS.
摘要:
Exhaustion process for dyeing anionically modified fibre materials with cationic dyestuffs from halogenated hydrocarbons, wherein are used cationic dyestuffs of the formula (F - (R)z) A in which F, R, z and A have the meaning given below in the disclosure; by the claimed process an essentially improved exhaustion of the dyebaths is achieved.
摘要:
The present invention relates to basic dyestuffs with a dibenzofuran system, their mixtures, processes for their manufacture and their use for dyeing and printing of natural and synthetic materials; particularly of polyacrylonitrile and copolymers of acrylonitrile with other vinyl compounds, and acid modified aromatic polyesters and acid modified polyamides, leather, tanned cotton, cellulose, polyurethanes and for the production of writing liquids and stamping inks.
摘要:
The dyeing or printing of polymers of acrylonitrile, polymers of as.-dicyanoethylene, or acid-modified aromatic polyesters, or acid-modified superpolyamides by using as a dyestuff a triarylmethane compound which is free from sulphonic acid and carboxylic acid groups, and has the formula
IN WHICH R is alkyl, aralkyl, cycloalkyl or aryl; R1 is hydrogen, alkyl, aralkyl or cycloalkyl; R2 is alkyl, aralkyl, cycloalkyl or aryl; R1 and R2 together with the nitrogen atom, or R1 or R2 with a carbon atom in the O-position in the ring A may form a heterocyclic ring; R3 is hydrogen, alkyl, aralkyl, aryl, alkoxy, aralkoxy, aryloxy, alkylmercapto, arylmercapto, halogen, carboxylic acid ester radical, carbonamido, sulphonamido, cyano, nitro, alkylsulphonyl, aralkylsulphonyl, arylsulphonyl, or acyl; and X is the radical of an anion.
