Chloroalkyl benzoate carrier - for dispersion dyes and brighteners in dyeing polyester, cellulose ester and polyvinyl chlori

摘要

Polyesters, e.g. polyethylene glycol terephthalate, cellulose ester, e.g. cellulose triacetate, and PVC articles, pref. textiles, are dyed with dispersion dyes, including optical brighteners, in the presence of chloroalkyl benzoates of formula: (where m is 2 or 3, and n is 0 or 1), pref. beta-chloroethyl-4- and/or -2-chlorobenzoate, which act as carriers, and may be used in 0.5-10 g./l. concn. of dye baths.
