Title: Dyestuffs of the amino-anthraquinone series
IPC: C09B1/20
Filed: 1965-11-24
Abstract: The invention comprises anthraquinone compounds of the formula <FORM:1074028/C4-C5/1> and their quaternary derivatives of the formula <FORM:1074028/C4-C5/2> wherein R1 is an aryl radical of the benzene or naphthalene series containing at least one halogen substituent in a position ortho to the amino group; R2 is a 1,4-phenylene radical or a C2-C4 alkylene radical; R3 and R4 are alkyl radicals or, together with the N atom to which they are attached, form a heterocyclic ring; R5 is alkyl, hydroxyalkyl, cycloalkyl or aralkyl; and A\sK is an inorganic or organic anion. They may be obtained by condensing a diamine of formula <FORM:1074028/C4-C5/3> with a 1-(o-haloarylamino) anthraquinone derivative of the formula <FORM:1074028/C4-C5/4> wherein X is a replaceable substituent, e.g. halogen, NO2 or lower alkoxy, in the presence of a condensing agent and a weak acid-binding agent in an inert organic diluent, and if desired, converting the anthraquinone base formed to the quaternary ammonium dyestuff by treating with a quaternizing agent in the presence of a solvent.  Several anthraquinones of the first formula above are specified.  An example is given for the preparation of 1-(21 - bromo - 41 - methylanilino) - 4 -(31-dimethylaminopropylamino) anthraquinone and the quaternary ammonium compound obtained by treatment with dimethyl sulphate.  The dyes are useful for dyeing acrylic fibres greenish-blue shades and in conjunction with CI Basic Yellow 11 to give a green shade.  The corresponding unhalogenated dyestuff trimethyl - (3 - [41 - p - toluidino - 11 -anthraquinonyl]aminopropyl) ammonium methyl sulphate is obtained by a similar method from 1 - p - toluidino - 4 - bromoanthraquinone and dyes acrylic fibres reddish-blue shades.ALSO:Polyacrylonitrile textiles are dyed with anthraquinone dyes of the formula: <FORM:1074028/D1-D2/1> where R1 is an aryl radical of the benzene or naphthalene series containing at least one halogen substituent in an o-position to the amino group; R2 is a 1,4-phenylene radical or a C2-C4 alkylene radical; R3 and R4 are alkyl radicals or together with the N atom form a heterocyclic ring; R5 is alkyl, hydroxyalkyl, cycloalkyl or aralkyl; and A is an inorganic or organic anion.  The dyes are preferably applied from mildly acidic aqueous dyebaths which may contain a surface active agent.  In an Example the dye is previously mixed with dextrin and pulverised.  Other dyes may be present such as CI basic yellow 11.
