Colouring preparations, comprising the following components: a) at least one, dispersed, poorly water-soluble colouring, b) water, c) at least one dispersing agent, d) a compound of general formula (I) in which the variables are defined as below: R1, R2 independently = H, (CH2-CH2-O)nH or (CH(CH3)-CH2-O)nH, where n = a whole number from 1 to 8, (CH2-CH2-O)a-(CH(CH3)-CH2-O)b-(CH2-CH2)c-(CH(CH3)-CH2-O)d-H, where a, b, c, and d are whole numbers from 0 to 7 and a + b + c + d = 9, R<3> = straight-chain C2-C10 alkyl, C6-C14 aryl, similarly or differently substituted with H or C1-C8 alkyl and CH2-0-R<4> where R<4> = C1-C10 alkyl. |
