Abstract
Abstract Aqueous dispersion of a sulfonated metallizable dye containing (a) based on the total weight at least 10% of the sulfonated metallizable dye and (b) a sulfonated condensation product obtained by reacting an aromatic compound having at least two replaceable ring-positioned hydrogen atoms in any desired order with a compound of the formula ##STR1## in which X is a direct bond or oxygen, Hal is chlorine or bromine and n is 1 to 4, and sulfonation.

Claim 1
Independent Claim
77 words
An aqueous dispersion of a mordant dye which comprises (a) at least 10% of a mordant dye, based on the total weight, and (b) a sulfonated condensation product, which is obtained by reaction of a monocyclic or polycyclic aromatic compound having at least two replaceable ring-positioned hydrogen atoms with a compound of the formula ##STR5## in which X is the direct bond or oxygen, Hal is chlorine or bromine and n is 1 to 4, and sulfonation.
Claim 2
Dependent Claim
77 words
