    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.

    Abstract: Linear aromatic polyester fibres or films are dyed or printed with an azo dyestuff free from sulphonic and carboxylic acid groups of the formula:- wherein X represents a hydrogen atom or an alkyl, aryl or aralkyl group, Y represents a cyano-alkyl group and Z represents a hydrogen atom, a halogen atom or an alkyl group, and the nucleus I may carry as substituents further nitro groups or alkyl, alkoxy, acylamino, sulphonic acid amido, carboxylic acid amido or substituted sulphonic acid amido and carboxylic acid amido groups. Dyeing may be effected at temperatures up to or above 100 DEG C., in the presence of carriers such as benzoic acid or o-hydroxybenzoic acid or their methyl esters, o- or p-phenylphenol or diphenyl, and in the presence of ionic and nonionic auxiliaries. Examples of dyeing and printing are given.

    IPC: D06P3/66

    Abstract: Fibres and foils of cellulose are dyed or printed by applying a dyestuff of the formula: in which A represents a tetrazaporphin radical, E represents an aromatic radical containing a mono- or bi-cyclic nucleus, Z represents a radical of the formula: in which R1 and R2 represent hydrogen atoms, alkyl or hydroxyalkyl groups or halogen atoms and R3 represents a hydrogen or halogen atom or an alkyl, hydroxyalkyl or carboxyl group, m is a number from 1-8 and n is a number from 0-4, and also applying an acid-binding agent before, together with or after the dyestuff. Specified acid-binding agents are alkali-metal or alkaline-earth metal hydroxides, carbonates and bicarbonates and alkali-metal phosphates. If necessary, fixation of the dyestuff may be effected by heating or steaming. The dyestuffs may be prepared by acylating a tetrazaporphin derivative of the formula: with acrylic acid chloride, a - methylacrylic acid chloride, a - chloracrylic acid esters, maleic anhydride or acrylic anhydride. Specifications 827,569, 853,364 and 858,184 are referred to.
