The effect of a number of auxiliary products of both the carrier and the non–carrier type on the levelling of disperse dyes under high–temperature (HT) conditions has been determined for a range of 12 dyes. The most effective products are carriers based on butyl benzoate, trichlorobenzene, diphenyl and benzyl benzoate. The effectiveness of a particular chemical type depends on its emulsification under dyebath conditions. Non–carrier agents show less improvement in levelling than all but the most ineffective carriers. Non–ionic agents can retard and restrain dyes, and can also adversely affect the dispersion stability of dyes.
