ABSTRACT:
Azo developing dyestuffs are produced by diazotizing on the fiber a mono- to tetramine derived from a metal-containing or metal-free phthalocyanine, the amino group(s) being bound to a phenyl or naphthyl group (which may be substituted) which is linked via a bridge member to the phthalocyanine which may further contain up to 3 optionally substituted sulfon amide groups and up to 3 sulfo groups, and coupling said diazotized amino onto azoic coupling components usual for preparing developing dyestuffs.
