Procedure

100 g of polyethylene terephthalate fibres in 4 l of water are dyed with 1 g of the dyestuff prepared according to the above example, which has first been brought to a finely divided state in the presence of dispersing agents, the dyeing being carried out in the presence of 15 g of o-cresotic acid methyl ester as the carrier for 2 hours at 100°C and pH 4.5. A brilliant yellow-tinged pink dyeing is obtained, which is distinguished by good built-up and high fastness to washing, thermofixing, rubbing and light. A similar colouration is obtained if polyester fibres from 1,4-bis-(hydroxymethyl)-cyclohexane and therephthalic acid are used.
