Abstract

The invention comprises anthraquinone dyestuffs of the general formula <FORM:1027968/C4-C5/1> in which Y is hydrogen or a group <FORM:1027968/C4-C5/2> where in X is -0-, -S- or -NR-; Y1 is hydrogen, hydroxyl, amino which may be substituted, or when Y is hydrogen, Y1 is a group <FORM:1027968/C4-C5/3> as defined above; R is hydrogen, an aliphatic radical which may be substituted, an aromatic group which may be substituted, or an acyl group, and the rings A, B and C may bear substituent groups othr than sulphonic acid groups. They may be prepared by reacting a compound of general formula <FORM:1027968/C4-C5/4> wherein Z is a hydrogen atom or a radical which can be exchanged for a group <FORM:1027968/C4-C5/5> as defined above and Z1 is hydrogen, hydroxy, amino, substituted amino or when Z is hydrogen Z1 is a group <FORM:1027968/C4-C5/6> as defined above with a compound <FORM:1027968/C4-C5/7> wherein C and X are as defined above in presence of a solvent and an acid binding agent. Any sulphonic acid groups in rings A and B are eliminated by reaction with sodium dithionite and sodium carbonate in aqueous solution. Specified solvents are C1-C4 alcohols, acetone and methylethyl ketone, 2-methoxyethanol and 2 ethoxyethanol. Examples of acid binding agents are sodium and potassium hydroxides, carbonates and bicarbonates, calcium and magnesium hydroxides, carbonates, trisodium phosphate and alkali metal acetates. Many examples are given and among the compounds claimed per se are (i) <FORM:1027968/C4-C5/8> (ii) <FORM:1027968/C4-C5/9> (iii) <FORM:1027968/C4-C5/100> (iv) <FORM:1027968/C4-C5/111> (v) <FORM:1027968/C4-C5/122>
