<p>Polyester fibers which have a linear density of less than 0.1 den and a polyurethane content cannot be dyed in deep, bloomy blacks with the commercially available black and navy mixtures based on blue, yellow and red disperse dyes. This problem is overcome by using blue components which are derived from mixtures of selected disperse dyes of diazotized 1-amino-2,6-dicyano-4-nitrobenzene and coupling components from the series of specifically substituted N,N-dialkylanilines as a constituent for the trichromatic system.</p> |
