    Abstract: The invention comprises the pigment of the formula The pigment is obtained by reaction of 1,9-pyrimidinoanthrone - 2 - carbonylic acid or an acid derivative thereof with 1-amino-4-methoxy-anthraquinone. Examples of acid derivatives are the carboxylic acid amides, esters and acid halides especially the chloride. The reaction is done in an inert solvent and/or diluent at temperatures preferably above 80 DEG C. When using the free carboxylic acid a halogenating agent, e.g. thionyl chloride, and a tertiary amine or low molecular weight aliphatic carboxylic amide are also employed in the reaction.

    Abstract: The compound of the formula: is obtained by reacting 1-(21-aminoethyl)-4, 5-dichloropyridazone -(6)- hydrochloride with m-nitrobenzene-sulphonic acid chloride in presence of aqueous sodium carbonate. The corresponding amine is obtained by reducing the nitro group in the above compound with iron powder acid aqueous acetic acid.ALSO:The invention comprises dyes of the azo, anthraquinone and phtholocyanine series which contain at least once in the molecule the radical of the formula in which D denotes a -SO2- or -CO- group, R denotes a hydrogen atom, an alkyl radical having 1 to 6 carbon atoms, a cycloalkyl radical, an aralkyl radical or an aryl radical, A denotes an alkylene radical with 2 to 6 carbon atoms in the chain, X denotes a chlorine or bromine atom and Y denotes a chlorine or bromine atom. Such dyes are prepared by reacting an acid halide of an appropriate dye or dye precursor with (a) an amine of the general formula or (b) with a hydrazone compound of the general formula and cyclizing the hydrazone derivative obtained by heating to a dihalopyridazone compound or (c) by reacting an appropriate dye or dye precursor which contains at least once the group of the general formula with mucohalic acid and the hydrazone formed as intermediate is cyclized in the reaction mixture or after isolation to form the dihalopyridazone derivative and in each process, (a), (b) and (c), when a dye precursor has been employed as starting material the product is converted to a dye. Of particular interest are dyes of the formulae where E denotes a phenylene, tolylene or diphenylene radical; where Q represents a sulphodiphenylene or a sulphonaphthylene radical; where Pc denotes the radical of copper phthalocyanine, a chlorocopper phthalocyanine with 1-4 chlorine atoms, a phenyl copper phthalocyanine with 1-4 phenyl radicals or nickel phthalocyanine, I denotes a phenylene radical, optionally substituted, D denotes a -SO2- or -CO- group, m denotes 1 or 2, p 1-4, q 1-3 and the sum of p+q 3-6; where L denotes the radical of a diazo component of the benzene or naphthalene series, M denotes the radical of a coupling component of the benzene, naphthalene or pyrazolone series D denotes a -SO2- or -CO- group, the remainder of the radicals in the last four formulae having the meanings given above. The copper, chromium or cobalt complexes of the o,o1-dihydroxyazodyes are also of interest. Examples are furnished. The dyes are suitable for dyeing and printing such materials as wool, silk, synthetic polyamides, leather and natural or regenerated cellulose.
