Asymmetric dioxazine compounds, intermediate compounds therefor and application of the asymmetric dioxazine compounds

摘要

An asymmetric dioxazine compound represented, when shown in free acid form, by the general formula (I): ##STR1## wherein T.sub.1 and T. sub.2 represent a hydrogen atom, a chlorine atom, a bromine atom, a lower alkyl group, a phenoxy group or others, A.sub.1 represents an alkyl group, a chlorine atom, a carboxyl group or others, A.sub.2 represents a hydrogen atom, an alkyl group, a chlorine atom, a carboxyl group or others, R represents a hydrogen atom or a lower alkyl group, X and Y represent a halogen atom, a fiber-reactive group or others, respectively, with the proviso that at least one of X and Y is a fiber- reactive group is provided.PPThe compound is suitable for dyeing or printing of a fiber material or the like which has a hydroxy group and/or an amide group, and provides a blue-dyed product with various fastness, including particularly chlorine fastness.
