ABSTRACT:
Condensation products, which can be obtained by a reaction of naphthols and alkanals, addition of alkylene oxides and more or less complete conversion of terminal hydroxy groups into sulfo groups or half-esters of maleic acid, phthalic acid or sulfosuccinic acid, are suitable for use as surface-active agents, in particular as coupling auxiliaries in the preparation of azo pigments and also as dispersing agents in the preparation of colorant dispersions and as wetting, emulsifying, leveling or dyeing auxiliaries.
