An aqueous dispersion comprising at least one of the UV absorbing compounds of the following formulae I, II or III as below defined: A--B (I); A--C--A (II); or B--A--B (III); wherein in Formula (I) and (II) ##STR1## and in Formula III, A is ##STR2## Y being a direct bond, a substitute C.sub.1-4 alkylene group, ##STR3## and R.sub.1 to R.sub.5 independently of each other are hydrogen; C.sub.4-4 alkyl, the alkyl optionally being substituted; aryl; heterocyclyl; or any two of R.sub.1 to R.sub.5 which are adjacent, together form part of a ring, with the proviso that no more than four of R.sub.1 to R.sub.5 are hydrogen.

Aqueous dispersions and their use for treating textiles

Textile dye-fixing agents

A process for the production of mineral tanned or/and re-tanned or/and after-treated leather or pelt, wherein before the mineral tanning, directly after the mineral tanning, directly before the mineral re-tanning, after the mineral re-tanning or/and with the after-treatment of a fatliquoring with a polyvalent metal cation, the substrate is treated with

Process for mineral tanning, re-tanning or leather after-treatment

Cationic fixing agents based on the reaction products of

Cationic polycondensates useful for improving the fastness of dyeings on

Compounds of formula I ##STR1## can be used as optical brighteners.

Triazinylaminobenzaldehydes

Polymeric compounds (A) obtained by the reaction of epihalo-hydrin with a polyalkylene polyamine are useful as textile treatment agents. As pretreatment agents they improve the color yield of the subsequent dyeing, as aftertreatment agents they improve fastness properties. Certain of the products (A) are novel.

Treatment of textile materials to improve the fastness of dyeings made

Aftertreatment of textile fibres which have been optically brightened or dyed or printed with certain direct dyes, or with basic or sulphur dyes, increases wet-fastness properties. The aftertreatment agent is a polymeric, polybasic amino compound, which is applied under alkaline conditions.

Aftertreatment of dyed or printed textiles with a polymeric polybasic

Polymeric compounds (A) obtained by the reaction of epihalohydrin with a polyalkylene polyamine are useful as textile treatment agents. As pretreatment agents they improve the color yield of the subsequent dyeing, as aftertreatment agents they improve fastness properties. Certain of the products (A) are novel.
