Abstract

Novel polycyclic dyes of the formula 1, in which the individual substituents have the meanings given in Claim 1, are prepared by converting compounds of the formula 2, in which the individual substituents have the meanings given in Claim 1, into the ring-closed compound of the formula 1 in acidic medium with the elimination of the radical A. The dyes are suitable for dyeing synthetic textile materials, in particular polyester fibres, and mass coloration of plastics. <IMAGE>
