The epindolidione compounds of the general formula (I) in which A', Rand A have the meanings given in claimare 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.

Epindolidione pigments

Preparation of trans-thiazineindigo pigments

Pigment for warpage-free polyolefins coloration

Heterocyclic compounds

The invention is directed to carbamate group containing non chloranil based triphendioxazine compounds useful as pigments which are readily convertible into the corresponding triphendioxazine pigments without carbamate.

Preparation of pigments

Hybrid pigments

New heterocyclic compounds are disclosed which are used as intermediates for the preparation of trans-thiazine-indigo pigments which are in part new compounds and can be used for the mass pigmentation of organic substrates. Also disclosed are different environmentally friendly water-based processes for the preparation of the new heterocyclic compounds and the corresponding pigments.
