Abstract:
The use is disclosed of hydrophilically modified polyisocyanates in the field of textiles: (i) as cross-linking agents for binders used in pigment dye liquors for dying textiles, (ii) in the form of aqueous dispersions which are substantially free of organic solvents and other emulsifiers, for finishing textiles, or (iii) for the production of textiles with wash-fast lustres.
Abstract:
Formaldehyde-free aqueous binders containing: A) a polymer consisting of 5 t o 100 wt% of an ethylenically unsaturated acid anhydride or an ethylenically unsaturated bicarboxylic acid, the carboxylic acid groups of which can form an anhydride group, and B) an alkanol amine with at least two hydroxyl groups.
