Properties and Applications

Bright red blue light. Soluble in ethanol, acetone and soluble fiber element, slightly soluble in benzene and carbon tetrachloride, insoluble in special solvent, tao. The strong sulfuric acid for brown, for dark orange after diluted. Used for polyester, polyamide fiber, acrylic, acetate fiber and three acetate fiber dyeing, sheepskin and plastic color. Good levelness, improve rate is high.
