Abstract

NEW MATERIAL:A 2:1 cobalt complex compound of the formula (where R1, R2, R3 and R4 are H, Cl, methyl nitro, sulfonic acid, sulfonamide; r1 and r2 are H, Cl; r3 and r4 are H, Cl, methyl, methoxy; and M is Na, K, NH4).
USE: Cobalt complex compound dye having good water solubility and capable of tinting natural and synthetic polyamide in vivid yellow which is superior in light fastness, weather fastness, wash fastness, etc.
PREPARATION: Said cobalt complex compound is produced by the reaction of a cobalt salt, such as cobalt chloride or cobalt acetate, with a mixture consisting of an azomethine dyestuff, which is produced by condensing o-aminophenols with salicylaldehydes, and an o,o'-dihydroxymonoazo dyestuff produced by diazotizing o-aminophenols and coupling the resultant with acetoacetanilide, etc.
