Copper containing azo triazine compounds

Abstract

Abstract WHERE TR ARE EACH MONOCHLOROTRIAZINE RESIDUES, BZ IS THE RESIDUE OF THE PHENYLENE DIAMINE DISULPHONIC ACID AND ME AND AZ ARE RESPECTIVELY THE RESIDUES OF THE METAL COMPLEX AND THE MONOAZO COMPOUNDS. ME-TR-BZ-TR-AZ WHERE R2 REPRESENTS H OR CH3, R3 REPRESENTS A 1,4-NAPHTHYLENE RADICAL WHICH MAY BE SUBSTITUTED BY SO3H AND/OR OCH3 OR A 1,4-PHENYLENE RADICAL WHICH MAY BE SUBSTITUTED BY CH3, OCH3, CL, CO2H, SO3H, NHCONH2 OR NHCOR5 WHERE R5 IS H OR AN ALKYL GROUP OF 1 TO 3 CARBON ATOMS, AND R4 REPRESENTS A SULPHONAPHTHYL RADICAL OR A MONO- OR DICYCLIC RADICAL OF THE BENZENE SERIES WHICH CONTAINS AT LEAST ONE SO3H GROUP AND WHICH MAY BE FURTHER SUBSTITUTED. THE CONDENSATIONS ARE CARRIED OUT IN SUCH A MANNER AS TO PROVIDE A PRODUCT OF THE FORMULA: NHR2-R3-N=N-R4 CELLULOSE-REACTTIVE DYESTTUFFS, PROVIDING USUALLY GREEN OR BROWN SHADES OF EXCELLENT FASTNESS TO LIGHT, WASHING AND BLEACH TREATMENTS AND PROVIDING A HIGH LEVEL OF FIXATION FROM ALKALINE, SALINE DYEBATHS ARE OBTAINED BY CONDENSING TOGETHER CYANURIC CHLORIDE (2 MOLES) WITH ONE MOLE OF A PHENYLENE DIAMINE SULPHONIC ACID, ONE MOLE OF A 1:1 COPPER COMPLEX AMINOAZO COMPOUND AND ONE MOLE OF NITROAMINOSTILBENE DISULPHONIC ACID OR AN AMINO MONOAZO COMPOUND OF THE FORMULA
