Title: New vat dyestuffs
Inventor: HOWARD HAROLD THOMPSON
IPC: C09B5/40
Filed: 1953-02-11
Abstract: The invention comprises dyes of the formula:-<FORM:0741312/IV(c)/1> wherein X is hydrogen or a 11-amino anthraquinone -21-carboxyamino group.  They are made by heating 11-amino or 3:11-diamino-benzanthrone -31 (N):41- anthraquinone -111(N) : 211- acridine with a halide of 1-aminoanthraquinone -2-carboxylic acid or with a halide of 1-nitro- or 1-chloro-anthraquinone -2-carboxylic acid or with a halide of 1-nitro- or 1-chloroanthraquinone -2-carboxylic acid and subsequently replacing the nitro or chloro groups by an amino group.  The nitro group may be reduced during vatting or otherwise with a reducing agent, e.g. ammonia.  The starting materials are made by condensing 3-bromobenzanthrone or 9-nitro-3-bromobenzanthrone with 1.5-diaminoanthraquinone or a 5-acylamino-1-aminoanthraquinone, fusing with caustic potash and hydrolyzing the acylamino group or reducing the nitro group as necessary.  The products give brown shades or cellulose fibres. In examples the 11-amino-and 3.11-diamino bodies are each acylated with 1-nitroanthraquinone-2-carboxylic acid chloride, in O-dichlorbenzene or nitrobenzene, followed by reaction with ammonia.  The Provisional Specification also describes the acylation of the 3-amino body with 1-nitroanthraquinone-2-caboxylic acid chloride, followed by reduction of the nitro group.  Specification 339,396, [Class 2(iii)], is referred to.
