Concentrated disazo dye-surfactant solution

An improved aqueous-organic solvent solution having a pH between 10 and 13, of the disazo dye ##STR7## wherein X is a cation selected from the group sodium, potassium, lithium, and ammonium, the improvement comprising the presence in the dye solution of a combination of

• i. 0.1% to 10.0%, by total weight, of an anionic surfactant, and
• ii. 0.1% to 10.0%, by total weight, of a nonionic surfactant, the ratio of anionic surfactant to nonionic surfactant being between 1 to 20 and 17 to 1, the dye solutin having a dye concentration in the range of 15% to 25% based on the total weight of the solution, said solution being nongelling upon dilution with water,
• the anionic surfactant being a water-soluble salt of at least one member of the group consisting of substituted benzenesulfonic acid salt, substituted naphthalenesulfonic acid salt, and sulfonated naphthaleneformaldehyde condensate salt,
• the nonionic surfactant being selected from at least one member of the group consisting of condensates of
• a. C.sub.4 to C.sub.24 alkyl primary amines and at least 5 moles of propylene oxide,
• b. C.sub.4 to C.sub.24 alkyl primary amines and at least 5 moles of ethylene oxide,
• c. C.sub.12 to C.sub.24 alcohols and at least 15 moles of ethylene oxide,
• d. C.sub.12 to C.sub.24 alcohols and at least 5 moles of propylene oxide,
• e. C.sub.4 to C.sub.24 alcohols and at least 8 moles of ethylene oxide and 2 moles of propylene oxide,
• f. alkyl phenols and at least 8 moles of ethylene oxide, and
• g. ethylene oxide and polypropylene ether glycol which is derived from propylene glycol and propylene oxide said glycol having a molecular weight from about 1,000 to 10,000, said condensate having a proportion derived from ethylene oxide of 20 to 80 weight percent.
