Additional patent to patent No. 41348 Patent valid from October 23, 1958. azo, containing chromium or cobalt. Such a complex is obtained if a mixture of two monoazo dyes of Formula 1 and Formula 2, in which X is nitro, chlorine or hydrogen, is treated with agents that give off cobalt or chromium so that two dye molecules receive one metal atom. It has been found that dyes with increased light stability can be obtained in a similar way if the monoazo dye of formula 3 is used instead of the monoazo dye of formula 2, where X is *). The patent owner stated that the inventors are Dr. Giinther Essbach and Kurt Lippold. a nitro group, or a chlorine atom, or a hydrogen atom, and Y is a nitro group or a chlorine atom. PL
