Use | The pigment variety is C.I. The bromination product of Violet 10 is reduced and has two different crystal forms: α-crystal form is obtained by dissolving and precipitating concentrated sulfuric acid, which has high coloring strength and transparency; the β-form product is obtained by heating the α-form product in N-methylpyrrolidone or stirring it with an organic solvent. Mainly used in industrial coatings and plastic coloring. |
