A reactive blue dye composition, which comprises a phthalocyanine dye represented by a free acid of the following formula (I), ##STR1## wherein CuPc is a copper phthalocyanine nucleus, W is a C.sub.2 -C.sub.4 alkylene group or a 1,3- or 1,4-phenylene group having one or two sulfo groups, R.sub.1 and R.sub.2 are independently a hydrogen atom or a lower alkyl group, 1 is a number of 1 to 3, m is a number of 0 to 2, and n is a number of 1 to 3, provided that the total number of 1, m and n is 4 or less, and a phthalocyanine dye represented by a free acid of the following formula (II), ##STR2## wherein CuPc, 1, m and n are as defined above, Y.sub.1 and Y.sub.2 are independently a hydrogen atom or a methyl, methoxy or sulfo group, R.sub.3 is a hydrogen atom or a lower alkyl group, and Q is --SO.sub.2 CH.dbd.CH.sub.2 or --SO.sub.2 CH.sub.2 CH.sub.2 Z in which Z is a splittable group by the action of an alkali, the mixing weight ratio of the dyes (I) to (II) in terms of a copper content being from 80 through 20 to from 20 through 80, which is useful for dyeing or printing fiber materials also in a blend with other color dyes such as yellow and red dyes to give dyed or printed products of a brilliant color excellent in fastness properties with high reproducibility.
摘要:
A water-insoluble disperse dye composition comprising a combination of a dye represented by the following formula (I), ##STR1## wherein X is hydrogen, halogen, lower alkyl or lower alkoxy, in an amount of 95 to 20% by weight, and a dye represented by the following formula (II), ##STR2## wherein Z, Y.sub.1 and Y.sub.2 are independently hydrogen or halogen, and the ring A is a benzene or naphthalene ring unsubstituted or substituted with a carboxylic acid ester group, in an amount of 5 to 80% by weight, which is useful for dyeing polyester fiber materials to obtain dyed products having both extremely high light fastness and excellent thermal resistance.
