Abstract
Colorant preparations contain the following ingredients: a) at least one dispersed, substantially water insoluble dye, b) water, c) at least one dispersant 1 d) a compound of the general formula I where R1, R2 are independently selected from hydrogen, (CH2—CH2—O)nH or (CH(CH3)—CH2—O)n—H, where n is an integer from 1 to 8; (CH2—CH2—O)a—(CH(CH3)—CH2—O)b—(CH2—CH2—O)c—(CH(CH3)—CH2—O)d—H, where a, b, c, d are each an integer from 0 to 7 and a+b+c+d=9. R3 is selected from straight-chain C2-C10-alkyl, C6-C14 aryl, identicallly or differently substituted by hydrogen or C1-C8-alkyl CH2—O—R4 where R4 is selected from C1-C10-alkyl.
