    Abstract: Water-soluble phthalocyanine dyes of the formula wherein Pc is the radical of a metal-free or metalliferous phthalocyanine, X is a divalent radical necessary to complete a heterocyclic ring, Y is an organic or inorganic anion and m is an integer from 1-6 are employed to dye textile materials of cellulose. They may be prepared as described in German Specification 1,097,596. Preferred heterocyclic rings are pyrrolidone, piperidine, hexamethyleneimine and morpholine. A number of dyes are specified.ALSO:Textile materials of natural or regenerated cellulose are dyed and/or printed with acid aqueous liquors or pastes containing water-soluble phthalocyanine dyes of the formula wherein Pc is the radical of a metal-free or metal-containing phthalocyanine, X is a divalent radical necessary to complete a heterocyclic ring, Y is an organic or inorganic anion and m is a integer between 1 and 6. The heterocycles completed by X are preferably pyrrolidine, piperidine, hexamethyleneimine or morpholine. The dye liquor preferably has a pH of 3-4, for which purpose acids may be added, and may contain neutral salts and other usual auxiliaries. Dyeing may be effected by the exhaust process or by the pad-steam, pad-hot air or pad-batch method. Printing may be carried out using an emulsion print paste. Examples of dyeing materials of cotton and spun rayon are given.
