    Abstract: A process for dyeing or printing cellulose textile materials with tetrazaporphin dyes of the formula T-(CH2-X)n in which T is the radical of a copper or nickel tetrazaporphin, X is a quaternary ammonium salt group which in turn bears a sulphonic acid, sulphonic acid amide, sulphonic acid ester or carboxylic acid, carboxylic acid amide, carboxylic acid ester or nitrile group and n is a whole number from 1 to 8, comprises applying the dye in the absence of weakly acid reacting agents and thereafter heating the material in the presence of an alkali at 50 DEG -150 DEG C. whereby an insoluble tetrazaporphin dye is deposited thereon. The said dyes may be used together with vat dyes or reactive dyes and fixed in the way usual for such dyes. Coloured discharges over dischargeable dyeings or coloured resists over aniline black or naphthol bottomings can be obtained by applying a printing paste containing the said dyes, an alkali and a reducing or discharging agent, e.g. sodium formaldehyde sulphoxylate thereafter heating the printed material at 98 DEG -106 DEG C. The specified alkalis are the carbonates and hydroxides of sodium and potassium and among the weakly acid reagents to be excluded are formic, acetic, trichloracetic, citric, lactic and maleic acid and sodium dihydrogen phosphate. Dyestuffs containing as the group X the preferred group may be prepared by reacting a copper or nickel phthalocyanin containing chloromethyl groups with the potassium salt of N,N-dimethylamino acetic acid in water at 90 DEG -95 DEG C. Examples of dyeing and printing, including resist and discharge printing, fabrics of cotton and spun rayon are given. Specifications 633,160, 686,036 and German Specification 843,725 are referred to.
