Abstract

NEW MATERIAL:A 1:2 type chromium complex compound shown by the formula I[A is a phenyl or naphthalene shown by the formula II or III (X1 and X2 are not dissociating substituent group, e.g., H, OH, halogen, nitro, sulfonic, acid, alkyl, etc.); Z+ H, Na, K, NH4 ion].
EXAMPLE: A compound shown by the formula IV.
USE: A colorant coloring alumium subjected to anode oxidation into black with providing improved light resistance, heat resistance, eluation resistance, etc.
PROCESS: For example, sulfamic acid is diazotized and coupled with a corresponding aminonaphtholsulfonic acid (J acid) in weak acidity to synthesize a monoazo dye first. This dye is coupled with 4,6-dinitro-2-aminophenol(picramic acid) diazotized in weak alkalinity to give a diazo mordant dye, which is converted with a chromium inparting agent into a complex, which is subjected to salting out and filtered.
