Mixture of water soluble reactive dyes and their use

A dye mixture consisting essentially of at least one blue dye, in an amount of about 5 to 95 weight percent, of the formula:

• ##STR8## wherein:
• R.sub.1 and R.sub.2 are independently selected from H and CI;
• Y is independently selected from a C.sub.2 -C.sub.6 alkylene group which may be interrupted by a hetero atom and the --NHCO-- group;
• W is independently selected from --OSO.sub.3 H, --SO.sub.3 H, and --COOH;
• Z is independently selected from --CH.dbd.CH.sub.2 and CH.sub.2 --CH.sub.2 --X;
• X is a group independently selected from --OSO.sub.3 H, --SSO.sub.3 H, --OPO.sub.3 H.sub.2 and an O-Acyl of the formula --O--CO--R wherein R is a C.sub.1 to C.sub.4 alkyl;
• and at least one red dye, in an amount from about 95 to about 5 percent by weight, of the formula:
• ##STR9## wherein:
• n is 0, 1, 2;
• R.sub.3 is selected from --H, --CH.sub.3, --OCH.sub.3 ;
• Z is selected from --CH.dbd.CH.sub.2 or CH.sub.2 --CH.sub.2 --X;
• X is selected from --OSO.sub.3 H, --SSO.sub.3 H, --OPO.sub.3 H.sub.2, and an O-Acyl of the formula --O--CO--R-- wherein R is a C.sub.1 to C.sub.4 alkyl.
