A dyeing assistant composition for use in applying color on hydrophobic fibers, consisting essentially of
- I. one or a mixture of esters of aliphatic hydrocarbon polyhydric alcohols having 2 to 8 hydroxyl groups selected from the group consisting of ethylene glycol, propylene glycol, glycerol, polyethylene glycol having an average of from 2 to 5 ethylene oxide units, sorbitan sorbitol, pentaerythritol, trimethylolethane and trimethylolpropane, with fatty acids having 6 to 22 carbon atoms, or ethylene oxide adducts of said esters, and
- II. one or a mixture of ethylene oxide adducts of aliphatic monoamines or diamines having 8 to 40 carbon atoms, or quaternary ammonium salts of said adducts,
- wherein the weight ratio of I:II is in the range of from 1:1 to 100:1.
