Pigmentviolet 23-Corimax Violet RLS

Pigment violet 23 is an organic compound that is a commercial pigment. It is member of the dioxazine family of heterocyclic compounds, but derived from carbazoles. It is prepared by condensation of chloranil and 3-amino-N-ethylcarbazole. It has a centrosymmetric angular structure. For many years, the structure was assigned, incorrectly, as having a "linear structure" (EC no. 228-767-9, CAS RN 6358-30-1) which differ in terms of the carbazole ring fusion.

Pigment violet 23 is prepared by condensation of an aniline with chloranil.[From Wiki]

Zeyachem is a global supplier of Dioxazine Violet pigments that provide a bluish violet shade, a color not obtainable by other pigments.

The extremely high color strength of Pigment violet 23 makes it a suitable pigment as a shading component. PV23 also exhibits excellent heat fastness and light fastness properties, making it suitable for inks and many paints and coatings applications.

Corimax Violet RLS is a reddish blue shade Dioxazine Violet (PV23) pigment with very high color strength and excellent overall fastness properties, suitable for inks, paints and coatings, including industrial coatings, powder coatings and automotive coatings.


low viscosity, high gloss, high color strength. Pigment Violet 23 is a transparent purple violet pigment with high saturation and tinting strength.

C.I.Pigment Violet 23 show good tinting strength in flexible PVC while poor resistance to immigration.

P.V.23 heat resistance above 230℃ in polyolefins, when used in transparent PS, temperature shall below 220℃, above this PV 23 shall decompose. When worked in polyester, it is 280℃ stable in 5 hours, while concentration shall above 0.05%.

The pigment is easy to use and requires no rinsing. To ensure maximum color intensity and proper adhesion to the pulp, a retention agent must be added to the pulp before the pigment is applied. Our pigments are supplied by volume sizes. The actual weight varies, depending upon the density of the pigment.


Anbefales til bilmaling, arkitektonisk belægning, coilbelægning, industriel maling, pulverbelægning, trykpasta, PVC, gummi, PS, PP, PE, PU, offset blæk, vandbaseret trykfarve, opløsningsmiddelfarve, UV blæk.

Pigment Violet 23 (PV 23) has now been around for more than 55 years. Its beginnings go back to 1928, when a patent was filed for the pigment after researchers at the Hoechst company in Germany first undertook the multistage synthesis based on carbazole, an ingredient of coaltar, and chloranile. Until the end of World War II the pigment was only used to process diamine light blue, a direct dyestuff for cotton.

With the invention of reactive dyes, which considerably simplified the dyeing and printing process for cellulose fibers, this application lost its importance. A new and promising use for PV 23 was quickly found due to the pigment’s ability to produce unique colors.

PV 23 has been used as a pigment since 1953. PV 23 belongs to the group of high-performance polycyclic pigments (HPP’s) that are used whenever the requirements for a colorant are particularly high. These include high light fastness and weather fastness, fastness to solvents, and heat stability. In addition, PV 23 stands out by its high coloring power. Under the electron microscope, the crude violet shows a highly granular crystalline form, whereas the pigment particles are miniscule.

Produktbrug:Pigmentviolet 23 bruges hovedsageligt til farvning af belægninger, blæk, gummi og plast samt til farvning af syntetiske fibre
Der er 124 slags kommercielle formuleringsmærker af pigmentet. Carbazoazine er en slags blå violet sort med stærk og usædvanlig anvendelse, og det specifikke overfladeareal for monolitfiolet RN er 74m2 / g. Det bruges i vid udstrækning inden for forskellige områder såsom belægning, trykfarver, trykning af plast og stof og farvning. Det har god hurtighed til at lakker, når der farves. Det kan bruges til lufttørrende maling, bilmaling OEM og bagningsmaling, især til latexmaling med CuPc-toner og stærk lys tone. Det kan bruges til plastfarvning med en varmemodstand på 280 ℃ i polyolefin og høj farveopbevaring (kun 0,07% af pigmentkoncentrationen er nødvendig for HDPE med 1 / 3SD); det kan også bruges til farvning af polyester og PE.

Syntese-princip: Carbazol anvendes som et råmateriale, og N-ethylering udføres under normalt tryk i nærvær af en faseinversionskatalysator, og en nitreringsreaktion og en reduktionsreaktion udføres for at syntetisere 2-amino-N-ethylcarbazol; 3,5,6-tetrachloroparaquinon (Chloranil) underkastes kondensations- og ringlukningsreaktioner, filtreres, vaskes med vand og tørres for at opnå en rå carbazol-violet; endelig, generel pigmenteringsbehandling ved æltning eller æltning for at opnå CI-pigmentviolet 23.
