Abstract
The invention comprises vat dyes of the formula <FORM:0986556/C4-C5/1> in which each R is an arylene residue, each X is the grouping -CONH- or -NHCO- and each A is a vattable anthraquinone residue and in which at least one of the residues A and R contains one or more acidic groups imparting solubility in water and in which the perylene residue may contain one, two or four halogen atoms or two alkoxy residues. Arylene residues mentioned for R are substituted or unsubstituted phenylene residues, naphthylene, diphenylene and stilbene residues. Vattable anthraquinone residues specified are those of acylamino anthraquinones, anthraquinone-acridone, acedianthrone, dibenzanthrone, isodibenzanthrone and anthrimide-carbazole. Acidic groups mentioned are sulphonic acid, carboxylic acid, sulphate ester and thiosulphate ester groups. The dyes are made (a) by sulphonating a vat dye of the above structural Formula (I) which does not contain acidic groups imparting solubility in water, (b) by mildly hydrolysing such a dyestuff containing sulphonic acid halide groups, (c) by acylating a vat dye of the formula <FORM:0986556/C4-C5/2> where R and X are as above and each of the symbols A represents a vattable anthraquinone residue containing an -NH2 group, and the perylene residue may contain the substituents mentioned above, either the vat dye or the acylating agent containing the acidic water-solubilizing groups, (d) by acylating a perylene of the formula <FORM:0986556/C4-C5/3> with an acylating agent of the formula A-CO-halogen or by condensing an amine A-NH2 with an acid halide of the formula <FORM:0986556/C4-C5/4> R and/or A containing an acidic water-solubilizing group, or (e) by oxidizing a vat dye of Formula I above, which contains an acylamino group having an -SH group to give an -SO3H group or by sulphating a vat dye having an acylamino group containing a -CH2SH group to give a thiosulphate group. Further, in examples, vat dyes of the Formula I above having acylamino groups containing sulphochloride groups are reacted with ethenolamine and the hydroxy groups then sulphated or are reacted with b -aminoethylthiosulphuric acid. The dyes dye and print natural or regenerated cellulose materials by the usual vat dyeing or printing methods.
