Abstract (en)

[origin: EP0690166A2] A process for dyeing cellulose or cellulose/polyester fibre materials (I) comprises modifying the material with amino gp.-contg. cpds. (II) and then dyeing with a fibre-reactive dispersion dye in supercritical CO2. Most pref. (I) are, e.g. 2-oxo-1,3-oxazolidine and corresp. derivs. thereof substd. with 4- or 5-aminomethyl or with 4- or 5-(trimethylammonium-methyl) gps. (chloride salt in the latter type) (5 cpds. listed), or 1-(trimethylammonium-methyl)- ethylene carbonate chloride. PREFERRED PROCESS - Dyeing is carried out at 70-200 (pref. 100-150) degrees C for cellulose fibre and 130-210 (pref. 130-150) degrees C for cellulose/polyester, with a CO2 pressure of 30-400 (pref. 140-250) bar.
