Liquid dye preparations: bis phenyl-azo-resorcinol in solvent for colored ribbon or ball pen ink

A liquid dye preparation containing at least one dye of the formula I ##STR9## where X is hydroxyl, amino or C.sub.1 -C.sub.15 -monoalkylamino,

• R.sup.1 and R.sup.4 are identical or different and each is independently of the other C.sub.1 -C.sub.15 -alkoxycarbonyl, wherein the alkyl group can be interrupted by from 1 to 3 oxygen atoms in ether function, a radical of the formula ##STR10## where Y is C.sub.1 -C.sub.13 -alkyl, which can be interrupted by from 1 to 3 oxygen atoms in ether function, or C.sub.1 -C.sub.15 -alkoxy, which can be interrupted by from 1 to 3 oxygen atoms in ether function,
• R.sup.2 and R.sup.5 can be identical or different and each is independently of the other hydrogen, nitro or chlorine, and
• R.sup.3 is hydrogen or C.sub.1 -C.sub.13 -alkyl, plus as solvent at least one product selected from the group consisting of benzyl alcohol, tridecanol, isotridecanol, glycol ethers, olein, C.sub.4 -C.sub.13 -dialkyl phthalates, C.sub.5 -C.sub.30 -chloroalkanes, C.sub.1 -C.sub.20 -alkanes disubstituted by phenyl, C.sub.1 -C.sub.10 -dialkylnaphthalenes and partly hydrogenated terphenyl,
• said dye preparation containing from 10 to 80% by weight, based on the weight of the preparation, of said dye.
