This invention relates to an anthraquinone dyestuff for cellulose containing fibers represented by the formula:
wherein R1 represents amino or hydroxyl, R2 represents hydrogen, chlorine, bromine, cyano or -SO2R wherein R represents methyl, ethyl or phenyl, R3 and R4 each represents hydrogen, amino, hydroxyl, nitro, chlorine or bromine, Y represents a connecting group consisting of -0- or -S-, one of X1 and X2 is hydrogen and the other is a group of the formula:
wherein -Z- represents a connecting group consisting of -O- or -S-, -W1 represents phenyl or -NR6R7, R5 represents hydrogen, methyl, ethyl, methoxy, ethoxy, chlorine or bromine, R6 and R7 each represents hydrogen or alkyl, alkenyl, cyclohexyl, aryl or aralkyl which may optionally be substituted by lower alkoxy, or NR6BR7 represents a 5- membered or 6-membered nitrogen-containing heterocyclic ring formed by combination of R6 and R7, and n is 0 or 1, with the proviso that where X2 is hydrogen, n is 0.
本发明涉及一种用于含纤维素纤维的蒽醌染料,由式表示:
其中R1代表氨基或羟基,R2代表氢、氯、溴、氰基或-SO2R,其中R代表甲基、乙基或苯基,R3和R4各自代表氢、氨基、羟基、硝基、氯或溴,Y代表由-0-或-S-组成的连接基团,X1和X2中的一个是氢,另一个是式中的基团:
其中 -Z- 代表由 -O- 或 -S- 组成的连接基团,-W1 代表苯基或 -NR6R7,R5 代表氢、甲基、乙基、甲氧基、乙氧基、氯或溴,R6 和 R7 各自代表氢或烷基、烯基、环己基、芳基或芳基,这些烷基、烯基、环己基、芳基或芳基都可以是氢、芳基或可任选被低级烷氧基取代的芳烷基,或 NR6BR7 代表由 R6 和 R7 组合形成的 5 元或 6 元含氮杂环,且 n 为 0 或 1,但在 X2 为氢的情况下,n 为 0。
