摘要:
The epindolidione compounds of the general formula (I) in which A′, R2 and A have the meanings given in claim 1, are outstanding pigments which are notable in particular for better migration, light and solvent fastnesses, better heat stability and enhanced colouring power and also better dispersibility and capability to be brought into pigment form. The invention also relates to a process for preparing these epindolidione compounds and to their use a colorants for colouring polymer compositions or paper pulps, as colorants in electrophotographic toners and developers, as colorants in ink-jet inks, as colorants in the coatings industry, as colorants for textile printing or as a printing ink in the graphical industry, as colorants in cosmetics.

摘要:
A process of forming the cis- or the trans-isomers of thiazine-indigo compounds comprising the step of reacting o-aminomercapto-carbocyclic or -heterocyclic compounds with a maleic acid or fumaric acid derivative in the presence of an aqueous system. The invention further relates to a process of converting cis-isomers of thiazine-indigo compounds into the trans-isomers being pigments. The invention also relates to the cis-isomers of thiazine-indigo compounds of formula I as defined in claim 14 which are new compounds.
