Solvent violet 13

Solvent Violet 13, also known as oil violet and C.I. 60725, is a synthetic anthraquinone dye with bright bluish violet hue. It is a solid insoluble in water and soluble in acetone, toluene, and benzene. Solvent Violet 13 is used to dye hydrocarbon products like solvents and petrol , thermoplastics, synthetic resins , e.g. , and synthetic fiber . It is also used in cosmetics, e.g. in hair and skin care products. In pyrotechnics , it is used in some violet colored smoke compositions.

1.45	189	0.63

Light fastness and heat resistance :

In GP-PS, transparent : 7 ; opaque :6-7(0.05% dyestuff+1.0% TiO2)

Generally, the values stated can also be applied to SAN, PMMA, PC and rigid PVC. For modified polystyrene, especially ABS, the fastness properties are lower.
