Abstract: The invention comprises water-soluble dyestuffs containing methylol groups and having the formula (HO3S)n-D-(Z)m where D is the radical of copper phthalocyanine, chlor-copper phthalocyanine having 1-4 chlorine atoms per molecule, phenyl-copper phthalocyanine having 1-4 phenyl groups per molecule, nickel phthalocyanine, iron phthalocyanine, aluminium phthalocyanine, diaza-copper phthalocyanine tetramethyl-dibenzo nickel tetrazaporphin or octaphenyl-nickel tetrazaporphin, Z is one of the radicals -SO2NH2, in which all hydrogen atoms capable of reacting with formaldehyde at a pH of 6 to 11 and a temperature of 0 DEG C. to 80 DEG C. are replaced by methylol groups, n is 1, 2 or 3, m is 1, 2 or 3 and (n+m) is 3 or 4, X is hydrogen or sulphonic acid and Y is hydrogen, sulphonic acid or methoxy. The dyestuffs are made by reacting the appropriate dyestuffs with formaldehyde under the conditions stated above. The preparation of the starting dyestuffs is described and examples are given. The dyes colour natural or regenerated cellulose and paper blue or green shades.
