Abstract
The invention comprises perinone dyestuffs, i.e. dyestuffs that contain one of the two groupings:- <FORM:0868470/IV(c)/1> or <FORM:0868470/IV(c)/2> where R is an aromatic residue fused in orthoor peri-positions and B and C are fused benzene rings, which contain at least one acid group imparting solubility in water and at least one residue of the formula:- <FORM:0868470/IV(c)/3> or <FORM:0868470/IV(c)/4> in which Z is a chlorine atom or an etherified hydroxyl group or a substituted or unsubstituted amino group. The dyes are made by reacting a perinone containing at least one acylatable amino group with b -chloro-propionyl chloride, cyanuric chloride or a 2 : 4-dichloro-1 : 3 : 5-triazine bearing in 6-position an etherified hydroxyl group or a substituted or unsubstituted amino group and, if desired, replacing in the dichloro compound obtained by using cyanuric chloride one of the chlorine atoms by an etherified hydroxyl group or by an amino group, the starting materials being chosen so that at least one of them contains an acid, water-solubilizing group and the reaction being carried out so that the product contains at least one mobile chlorine atom. The dyestuffs dye and print polyhydroxylated materials such as natural or regenerated cellulose or polyvinyl alcohol fibres in conjunction with an alkali and heat treatment in a variety of shades.

METHOD FOR DYEING AND TYPING OF TEXTILE MATERIALS 1 The invention relates to a method of dyeing and printing textile materials with vat dyes. Known methods of dyeing and printing textile materials using vat dyes, which are characterized by a certain temperature, pH value, content of hydrosulfite and salt. according to which shells are used as dyes of formula IA-NH-XY-Tv i -,., where A is the residue forming a cube, X is a heterocyclic residue with two k ring nitrogen atoms linked through —NH— a group with a ring carbon atom directly or through —CO — group; Y — an oxygen or sulfur atom; R is an azo-grouped aromatic residue that is bonded to an oxygen or sulfur atom (Y) through an aromatic carbon atom; moreover, if R is a heterocyclic residue, then it is at least a six-membered heterocyclic aromatic residue; Z is the residue —NH-A 'or the residue —Y — A', where Y has the above value and A'is the residue forming the cube; n = 1 or 2, and if X is a pyrimidine residue, Z is NH — A ', A and A' are unsubstituted anthraquinone residues, —Y — R is not an unsubstituted phenoxy residue. Of particular interest are dyes of the formula I, in which residue X means quin-oxalin —CO—, quinazoline —CO— or fta-lasine —OC — residue and n ezhde all pirimi- dinostatok. The residue X may be bonded to the —Nn — bridge via the —CO — group, for example, compounds of the formula 20 NH — CO 2530 where X — preferably directly bonded to — NH — through a ring carbon atom.
