    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.

    Abstract: In Examples 1-6 dyes of the anthraquinone and naphthalene series are chloromethylated and then reacted with ammonia, primary or secondary amines or heterocyclic nitrogen containing compounds to give dyes having at least one radical of formula directly attached to the aromatic rings of the dye and in which the group denotes a radical of ammonia or of a primary or secondary amine, or R1 and R2 are joined with the N atom to form a heterocyclic ring system, and X is an organic or inorganic anion. The dyes are substantially free from water solubilizing groups, but are slightly water soluble due to the above groups.ALSO:The invention comprises a process in which textile materials containing hydroxyl groups are dyed in neutral or acid liquors or pastes with dyes having at least one radical or formula in which -NR1R2 is the ammonia group or a primary or secondary amino group. R1 and R2 may be joined p together with the nitrogen atom to form a heterocyclic ring, the anion X being organic or inorganic. The dyes used are slightly soluble in water.
