This invention relates to the use of tannin for improving the ozone fastness of dyed and undyed polyamide-containing material, which comprises applying tannin to, or incorporating it into, the polyamide-containing material.

Ozone stability of dyed and undyed polyamide-containing material

The present invention relates to novel dyeing assistant preparations comprising, as component (a), at least one amine oxide of the formula ##STR1## in which R is an aliphatic radical having 8 to 24 carbon atoms and

Dyeing assistant preparations and their use for dyeing wool

A process for dyeing textile materials of naturally occurring and synthetic polyamide fibres, in which dyeing is carried out at the boiling point of the dyebath during a short dyeing time which is therefore gentle on the fibres, and level dyeings having good fastness properties are obtained (high temperature rapid dyeing process). The dyeing process is carried out with dyebaths with comprise specific surfactants. A high degree of exhaustion of the dye liquors is achieved, and dyeing from static baths is thus rendered possible.

Process for dyeing naturally occurring or synthetic polyamide fibres

Aqueous stable dispersions of a mixture of sparingly soluble UV absorbers, which comprises (a) 5 to 50% by weight of a mixture of a benzotriazole of formula ##STR1## and a 2-hydroxybenzophenone of formula ##STR2## wherein R is halogen, C.sub.1 -C.sub.12 alkyl, lower alkoxy, lower alkoxycarbonyl, cycloalkyl, aryl, C.sub.1 -C.sub.12 alkylaryl or aralkyl, and the rings A and B, each independently of the other, may be further substituted by halogen, hydroxy, lower alkyl, lower alkoxy or lower alkoxycarbonyl,

Aqueous dispersion of sparingly soluble UV absorbers

There are described novel storage-stable liquid detergent compositions which comprise

Liquid detergent compositions containing fluorescent whitening agents,

There are disclosed aqueous dispersions comprising water-insoluble or sparingly soluble fluorescent whitening agents, dispersants, further optional assistants and a copolymer of 2-vinylpyrrolidone and 3-vinylpropionic acid, their preparation and the use thereof for whitening textile fibre materials. These novel dispersions are storage-stable.

Whitener dispersion

There are disclosed aqueous dispersions comprising water-insoluble or sparingly soluble fluorescent whitening agents, water-soluble fluorescent whitening agents, dispersants, optional solubilizers, further optional assistants and a copolymer of 2-vinylpyrrolidone and 3-vinylpropionic acid, their preparation and the use thereof for whitening polyester/cellulose fiber material. These novel dispersions are storage-stable and temperature-stable.

Aqueous stable dispersion of UV-absorbing 2-(2'-hydroxyphenyl)benzotriazole compounds containing
