Pigment Violet 23
Pigment Violet 23 belongs to the dioxazine group, and it is the most typical variety in dioxazine pigments. PV23 has good resistance to most organic solvents, and is recommended for most applications. Its basic hue is reddish violet, but the blue shade can also achieved by special treatment. It has high tinting power in different applications. A satisfactory color depth can be obtained by adding small amount of PV23. It is widely used in inks,paints, plastics, textile printing and dyeing. With the color of PV23, the paint has good fastness to varnish.It is also used for the color of plastics. The heat resistance in Polyolefincan reach 280℃. Its good weather and light fastness Good light and weather fastness make it suitable for printing ink and textile printing.
