摘要:
A reactive dye composition comprising an anthraquinone compound of formula:
wherein Z represents -CH=CH 2 or -CH 2 CH 2 Z 1 in which Z 1 represents a group removable by the action of an alkali other than a carboxypyridinio group and an anthraquinone compound of formula (II):
and a method for dyeing or printing cellulose-containing fiber materials using the same.
摘要:
Anthraquinone compounds of the formula, wherein R is hydrogen, alkyl or the like, R 1 and R 2 are each hydrogen, halogen or sulfo, ℓ is 1 or 2, X is sulfo or the like or -V-A-(W) m -Z, and Y is -V 1 -A 1 -U, wherein V and V 1 are each -0- or -S-, A and A 1 are each a divalent group such as W is -NH- or the like, Z is hydrogen or a fiber reactive group, and U is hydrogen, a fiber reactive group or a fiber reactive group-containing group, provided that at least one of Z and U is or has a fiber reactive group, which is useful for dyeing or printing fiber materials such as cotton to give a dyed or printed product having excellent fastness properties, particularly those such as light fastness and perspiration-lightfastness.
