A compound of the formula, ##STR1## wherein R.sup.1 is methyl or ethyl, R.sup.2 and R.sup.3 are each C.sub.5 -- or C.sub.6 --alkyl, and Z is chlorine for use as a blue disperse dye of hydrophobic fibers, either alone or as a mixed dye in combination with anthraquinone; the compound combines low cost relative to anthraquinone with superior stability in the dye bath and excellent dyeability; mixed dyes retain anthraquinone-imparted brilliance of color, have good color fastness, dyeability and reproducibility characteristics, and maintain low cost.

2-Cyano-4-nitro-6-chlorophenylazo 3-acetyl-or

A dye, which is suitable for dyeing cellulosic fiber materials, of the formula, ##STR1## wherein R and R' are each hydrogen, a C.sub.1 -C.sub.4 alkyl, or C.sub.1 -C.sub.4 hydroxyalkyl, m is an integer of 1 to 6, n and n' are each an integer of 2 to 4, and when m is 2 or more, n may be the same or different integer between 2 and 4, X is hydrogen or a group of the formula ##STR2## (wherein Q is a dye residue, R.sub.1 is hydrogen or a C.sub.1 -C.sub.4 alkyl and R.sub.2 is halogen); Y is hydrogen or a group of the formula ##STR3## (wherein Q' is a dye residue, and when m is 2 or more, Q's may be the same or different, R.sub.1 ' is hydrogen or a C.sub.1 -C.sub.4 alkyl and R.sub.2 ' is halogen); Z is hydrogen or a group of the formula ##STR4## (wherein Q' is a dye residue, R.sub.1 ' is hydrogen or a C.sub.1 -C.sub.4 alkyl and R.sub.2 ' is halogen, Q, Q' and Q' may independently be the same or different and X, Y and Z are not hydrogen at the same time).

Triazinyl-antraquinone dyes

A dye, which is suitable for dyeing cellulosic fiber materials, of the formula, ##STR1## wherein R and R' are each hydrogen, a C.sub.1 -C.sub.4 alkyl, or C.sub.1 -C.sub.4 hydroxyalkyl, m is an integer of 1 to 6, n and n' are each an integer of 2 to 4, and when m is 2 or more, n may be the same or different integer between 2 and 4, X is hydrogen or a group of the formula ##STR2## (wherein Q is a dye residue, R.sub.1 is hydrogen or a C.sub.1 -C.sub.4 alkyl and R.sub.2 is halogen); Y is hydrogen or a group of the formula ##STR3## 1 (wherein Q' is a dye residue, and when m is 2 or more, Q's may be the same or different, R.sub.1 ' is hydrogen or a C.sub.1 -C.sub.4 alkyl and R.sub.2 ' is halogen); Z is hydrogen or a group of the formula ##STR4## 5 (wherein Q' is a dye residue, R.sub.1 ' is hydrogen or a C.sub.1 -C.sub.4 alkyl and R.sub.2 ' is halogen, Q, Q' and Q' may independently be the same or different and X, Y and Z are not hydrogen at the same time).

Metallized triazine reactive dyes

A dye, which is suitable for dyeing cellulosic fiber materials, of the formula, ##STR1## wherein R and R' are each hydrogen, a C.sub.1 - C.sub.4 alkyl, or C.sub.1 - C.sub.4 hydroxyalkyl, m is an integer of 1 to 6, n and n' are each an integer of 2 to 4, and when m is 2 or more, n may be the same or different integer between 2 and 4, X is hydrogen or a group of the formula ##STR2## (wherein Q is a dye residue, R.sub.1 is hydrogen or a C.sub.1 - C.sub.4 alkyl and R.sub.2 is halogen); Y is hydrogen or a group of the formula ##STR3## (wherein Q' is a dye residue, and when m is 2 or more, Q's may be the same or different, R.sub.1 ' is hydrogen or a C.sub.1 - C.sub.4 alkyl and R.sub.2 ' is halogen); Z is hydrogen or a group of the formula ##STR4## (wherein Q' is a dye residue, R.sub.1 ' is hydrogen or a C.sub.1 - C.sub.4 alkyl and R.sub.2 ' is halogen, Q, Q' and Q' may independently be the same or different and X, Y and Z are not hydrogen at the same time).
