Abstract
The extensive amount of work which has been carried out to increase dispers e dye substantivity for cellulosic fibres is critically assessed. From the viewpoint of the practical colourist it is important that such systems shou ld be operable in aqueous media. A water soluble acylating agent, sodium be nzoylthioglycollate, (BTG) was therefore synthesised and characterised. The stability of BTG to hydrolysis in aqueous media was determined, together w ith its reactivity towards other nucleophiles. (C) 1999 Elsevier Science Lt d. All rights reserved.
