Product Description of Pigment Violet 23:

Mainly used for coloring of coatings, inks, rubber and plastics, and also used for coloring of synthetic fibers.Carbazosin is a violet product with strong comprehensive application and unusual high color strength. The specific surface area of Monolite Violet RN is 74m2/g. Widely used in coatings, printing inks, plastics and fabric printing and dyeing, etc.: It has good fastness to varnish when the coating is colored. It can be used for air-drying paint, automotive coating OEM and baking paint, especially for CuPc color mixing. It is used for coloring of plastics, heat-resistant to 280°C in polyolefin, and has high tinting strength (HDPE up to 1/3SD only needs a pigment concentration of 0.07%); also used for polyester and PE raw materials Pulp coloring.

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.
