Abstract
The disperse dyeability of a fiber or film forming polyester resin is improved by dispersing substantially uniformly in a polyester resin in which it is at least partially soluble a compound having the formula ##STR1## wherein R is benzyl or phenethyl, R.sub.1 is ethylene or propylene, R.sub.2 is hydrogen or lower alkyl and M is an alkali metal.
