Novel series of some plane‐rigidized heterocyclic dyestuffs for synthetic polymer fibres

Abstract

Since knowing the effective role of amidic functions in producing new dye‐stuffs of high thermal fastness and low solubility (e.g. Hostaperm or PV Fast (Hoechst)), great attention has been directed towards the synthesis and use of several dyes and pigments having such moieties. The majority of these dyes are characterized by their tendency to form stable dimers. Sometimes, these dimeric monoazo pigments have the same thermal solvent fastness as disazo pigment dyes of the Cromophtal type (Ciba‐Geigy).
