Abstract

Light-fast condensation products are prepared by (a) reacting one or more sulphonated phenols, free from condensed rings, with a water-soluble urea-formaldehyde condensate which may be partially etherified and (b) aftertreating the reaction product with one or more phenols, free from condensed rings, and formaldehyde or with one or more preformed condensates of such phenols and formaldehyde. The sulphonated phenols are the sulphonation products of phenol, alkylphenols, halophenols, bis-phenols and diphenylol sulphone. The phenols used in the after-treatment include phenols, halophenols, alkylphenols, bis-phenols, diphenylolsulphone and their sulphonation or sulphomethylation products, polyhydric phenols such as catechol and partially O-alkylated polyhydric phenols. The condensation products may be dried by evaporation in vacuo or by roller or spray drying. Examples are given. Uses: As tannins and as auxiliaries in dyeing. Specification 478,280 is referred to.
