Abstract
Polyester fiber materials are colored by contacting them with aqueous compositions containing an organic pigment or a vat dyestuff or both and an oxpropylate of a mono- to hexahydric alkanol of 2 to 6 carbon atoms (containing 20 to 60 propylene oxide units) and fixing in a manner which is common for polyester. The colorations are fast to migration, especially to bleeding into PVC-coatings.
