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
