Dark red uniform powder. Dissolved in water, it has a bright peach color. When dyeing at high temperature (120℃), the color and light remain unchanged. If dyed in sulfuric acid bath, the color and light change slightly, if dyed in formic acid bath, the color and light remain unchanged. Sunlight fastness grade 4. Compatibility value K=4.
Astrazone pink FG is a pink dye.
1,3,3-Trimethyl-2-methyleneindoline and 4-((2-Chloroethyl)(methyl)amino)benzaldehyde?condensation, and then into chloride.
