Abstract
NEW MATERIAL:The compound of formulaI(X is H or sulfonic acid group; the azo group and the sulfonic acid group bonded to the naphthalene ring to which X is bonded are adjacent to each other) as free acid.
EXAMPLE: The compound of formula II.
USE: A dye which dyes an OH-group-containing substance such as cotton, viscose rayon, etc. in blueWblack color with excellent exhaustion ratio, fixing ratio, and build-up property. The dyed product has excellent color fastness to light, sun-light, and especially chlorine.
PROCESS: The objective compound can be prepared e.g. by coupling the monoazo dye of formula III with the diazotized naphthylamine sulfonic acid derivative of formula IV (amino group is adjacent to sulfonic acid group).
