Abstract

Dyes have formula: (where Z is H, Me, Et, OMe or OEt; R1 and R2 are Me or Et; R3 is Me, Et or Ph opt. substd. by Me, Et, OMe or OEt). They are used for dyeing hydrophobic fibres, esp. polyesters, and also for colouring synthetic resins. Pref. mixtures of >=2 dyes are used, when colouring power is increased and fast blue shades are obtd.
