A process for colouring a synthetic textile material or fibre blend thereof which comprises applying to the synthetic textile material a compound of formula (1) wherein Ring A and Ring D are optionally substituted and at least one of Ring A or Ring D carries at least one -SO2F group except for 2-[(9,10- dihydro-9,10-dioxo-1-anthracenyl)amino]-ethanesulphonylfluoride, 2-[(9,10- dihydro-9,10-dioxo-2-anthracenyl)amino]-ethanesulphonylfluoride, 2,2'-[(9,10- dihydro-9,10-dioxo-1,4-anthracenediyl)diimino]bisethanesulphonylfluoride, 2,2'- [(9,10-dihydro-9,10-dioxo-1,5- anthracenediyl)diimino]bisethanesulphonylfluoride, 2,2'-[(9,10-dihydro-2- methoxy-9,10-dioxo-1,4-anthracenediyl)diimino] bisethanesulphonylfluoride, 2- [(4-(benzoylamino)-9,10-dihydro-9,10-dioxo-1-anthracenyl)amino] ethanesulphonylfluoride, 2-[(9,10-dihydro-4-(methylamino)-9,10-dioxo-1- anthracenyl)amino]ethane sulphonylfluoride.

La présente invention concerne un procédé de coloration d'une substance textile synthétique ou d'un mélange de fibres de cette substance. Le procédé consiste en l'application à ladite substance d'un composé conforme à la formule générale (1). Dans ladite formule générale, l'anneau A et l'anneau D sont éventuellement substitués et l'un au moins des anneaux A et D porte au moins un groupe -SO¿2?F à l'exception du 2-[(9,10-dihydro-9,10-dioxo-1-anthracényle)amino]-éthane sulfonylfluorure, du 2-[(9,10-dihydro-9,10-dioxo-2-anthracényle)amino]-éthane sulfonylfluorure, du 2,2'-[(9,10-dihydro-9,10-dioxo-1,4-anthracénédiyle)diimino]-biséthane sulfonylfluorure, du 2,2'-[(9,10-dihydro-9,10-dioxo-1,5-anthracénédiyle)diimino]-biséthane sulfonylfluorure, du 2,2'-[(9,10-dihydro-2-méthoxy-9,10-dioxo-1,4-anthracénédiyle)diimino]-biséthane sulfonylfluorure, du 2-[(4-benzoylamino)-9,10-dihydro-9,10-dioxo-1-anthracénédiyle)amino]éthane sulfonylfluorure, du 2-[(9,10-dihydro-4-(méthylamino)-9,10-dioxo-1-anthracénédiyle)amino]éthane sulfonylfluorure.
