Compounds consisting of an oligomer or a polymer of a 1,3,5-triazine derivative, having the general formula I: and a solvent-free process for the production of the compounds of Formula I as well as the use of the self-extinguishing oligomeric or polymeric compounds as flame retardants and light stabilizers in thermoplastic polymers such as polypropylene or regenerated cellulose or polyester.

Polytriazinyl compounds as flame retardants and light stabilizers

The present application relates to compounds of formula A(D)(E), (I), compounds of formula (III), compounds of formula (X), as well as processes for the preparation thereof, processes where the compounds (I) are converted to pigments of formula (II) and the use of the compounds (I).

Solvent-free process for the preparation of diketopyrrolopyrrole derivatives

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

This invention relates to copolymer compositions having pigment like properties, comprising a fluorescent or non-fluorescent dye attached to a polymer chain by a spacer having a chain length of Cor longer. The invention also provides for new mono- and difunctional dye monomers comprising a polymerizable group attached to a dye moiety by a spacer of a chain length of Cor longer. The polymer pigments provide excellent properties, especially high temperature stability and easy applicability as colorant in different standard polymers.

Copolymer composition having pigment like properties

Pigment for warpage-free polyolefins coloration

Triphendioxazine compounds

This invention relates to new fluorescent or non-fluorescent dye compounds having a terminal hydroxy, carboxylic acid/ester or amino group and a process for their preparation. The new fluorescent or non-fluorescent dye compounds are useful as colorants for preparing colored synthetic polymer resins with pigmentary properties, for dyeing or printing homo- or mixed synthetic, semi-synthetic or natural polymers or substrates or for preparing inks. The dye compounds provide excellent properties, especially high temperature stability and easy applicability.

Dye compounds

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.

Hybrid pigments

Yellow pigmented food package

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.

Process for the preparation of thiazine-indigo compounds and of new intermediates therefor

A new polymorphic form of 2,9-dichloroquinacridone having improved pigmentary properties and a method of forming said 2,9-dichloroquinacridone comprising the step of ring closure of appropriately substituted terephthalic acid in sulphuric acid.

Quinacridone pigment

A new pigment for making colored finely divided particles on aminoformaldehyde resin allows to produce particles of substantially uniform particle size and spherical or irregular shape having excellent dispersibility and superior opacity.
