Disperse dye mixture

A disperse dye mixture comprising a monoazo dye of the following formula (I) and a monoazo dye of the following formula (II) blended at a ratio of from 0.1 to times by weight of the dye of the formula (II) to the dye of the formula (I):

• ##STR58## wherein X is a halogen atom, a nitro group, a cyano group, a thiocyanate group, a methylsulfonyl group, a C.sub.1 or C.sub.2 alkylcarbonyl group, a C.sub.1 -C.sub.4 alkoxycarbonyl group or a vinylsulfonyl group, Y is a hydrogen atom, a halogen atom, a cyano group, a trifluoromethyl group or a methylsulfonyl group, W is a hydrogen atom, a halogen atom, a C.sub.1 or C.sub.2 alkyl group or a C.sub.1 or C.sub.2 alkoxy group, and each of R.sup.1 and R.sup.2 which are independent of each other, is a hydrogen atom, a C.sub.1 -C.sub.8 alkyl group, or a C.sub.2 -C.sub.4 alkyl group substituted by a halogen atom, a hydroxyl group, a cyano group, an alkoxy group, an alkoxyalkoxy group, a hydroxyalkoxy group, a hydroxyalkoxyalkoxy group, an acyloxyalkoxy group or an acyloxyalkoxyalkoxy group, provided that each alkoxy group has from 1 to 4 carbon atoms.
