Abstract

Process for the preparation of water-soluble metalized disazo dyes, characterized in that complex, heavy metal complexes of disazo dyes which correspond as free acids to the formula are prepared by metallization, coupling or esterification R2 - n = n - r - n - n = n - r1 Where The central component R represents the radical of a coupling component of the resorcinic or naphtorosorcinic series, respectively linked ortho to an oxy group on the two azo bridges, R1 represents the radical, attached in an ortho position to a complex forming group to the azo bridge, of a diazo component of the benzene or naphthalene series preferably containing aqueous-lubricating and R2 represents the radical of a diazo component lacking complex forming groups located ortho to the azo bridge, And wherein there is at least one sulfonalkylamido group attached to r1 and/or r2 with an inorganic O-ester group.
