Abstract

A compound of Formula (1) and salts thereof wherein: A is optionally substituted phenylene; B and E are each independently optionally substituted phenylene or optionally substituted naphthylene; D is a coupling component: each R<SP>1</SP> independently is H or optionally substituted alkyl: X is a labile atom or group; and each Y independently is O or S. The compounds are useful for the coloration of a wide variety of substrates, particularly cellulosic substrates by the pad-dry-bake method.
