Abstract
Abstract The invention relates to an aqueous disperse dye or optical brightener formulation which comprises (a) from 5 to 55 percent by weight, based on (a+c), of one or more finely divided dyes, optical brighteners or mixtures of these, (b) from 10 to 200 percent by weight, based on (a), of a water-soluble surfactant of the formula ##STR1## where X is from 0 to a mean value of 125, Y is from a mean value of 37 to a mean value of 250, but if X is >37, Y:X is at least 1:1, Z is 0 or 1 and Me⊕ is an alkali metal ion, or mixtures of such surfactants, (c) from 45 to 95 percent by weight, based on (a+c) of water or of a mixture of water and a water-retaining agent, with or without (d) further additives conventionally present in aqueous formulations.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
154 words
A stable finely dispersed aqueous formulation of disperse dyes and optical brighteners, which contains (a) from 5 to 55 percent by weight based on (a+c), of one or more finely divided disperse dyes, optical brighteners or mixtures of these, (b) from 10 to 200 percent by weight, based on (a), of a water-soluble surfactant of the general formula ##STR10## where X is from 0 to a mean value of 125, Y is from a mean value of 37 to a mean value of 250, but if X is >37, Y:X is at least 1:1, Z is 0 or 1 and Me⊕ is an alkali metal ion, or mixtures of such surfactants, (c) from 45 to 95 percent by weight, based on (a+c) of water or of a mixture of water and water-retaining agent, and (d) from 0 to 2.5 percent by weight, based on the formulations, of a disinfectant, pH regulator or mixture thereof.
Claim 2
Dependent Claim
154 words
A stable finely dispersed aqueous formulation of disperse dyes and optical brighteners, which contains (a) from 5 to 55 percent by weight based on (a+c), of one or more finely divided disperse dyes, optical brighteners or mixtures of these, (b) from 10 to 200 percent by weight, based on (a), of a water-soluble surfactant of the general formula ##STR10## where X is from 0 to a mean value of 125, Y is from a mean value of 37 to a mean value of 250, but if X is >37, Y:X is at least 1:1, Z is 0 or 1 and Me⊕ is an alkali metal ion, or mixtures of such surfactants, (c) from 45 to 95 percent by weight, based on (a+c) of water or of a mixture of water and water-retaining agent, and (d) from 0 to 2.5 percent by weight, based on the formulations, of a disinfectant, pH regulator or mixture thereof.
