摘要：
Since anthraquinonoid disperse dyes of the dark blue and navy region give only a low color strength on synthetic fibers, there was an urgent need for their coloristically advantageous substitution by high performance blue azo dyes which are suitable for being used in the carrier dyeing process.According to the invention, the systematic development of multi-component mixtures based on selected blue azo dyes from the dicyano azo series makes it possible to avoid most of the disadvantages mentioned.
