Abstract

2 - (21 - hydroxybenzylidene - amino)-4:6-diamino-1:3:5-triazine is prepared by reacting salicyl aldehyde with melamine in N-methylpyrrolidone. 2 - (41 - aminophenylsulphonylamino)-4:6-diamino-1:3:5-triazine is prepared by reacting melamine with 4 - nitrobenzene - sulphonyl chloride and reduction of the nitro group.ALSO:The invention comprises water-soluble dyes of formula [D]-(CH2OH)n wherein D is the residue of an azo or anthraquinone dyestuff containing at least one water-solubilising group and containing at least one 2 : 4-diamino-1 : 3 : 5-triazine group in the molecule and in which hydrogen atoms susceptible to reaction with formaldehyde have been replaced by methylol groups and n is 1 to 8. They are prepared by reacting a suitable dye or intermediate with formaldehyde or an agent giving formaldehyde such as paraformaldehyde, formaldehyde diethylacetyl or N-methylolurea in a medium of pH 6 to 11 and if necessary converting the intermediate to an azo or anthraquinone dye. The dyes give yellow and red shades on cellulose, polyamide and polyurethane fibres preferably in the presence of acids or acid salts and the dyed goods may be heated. In Examples: (1) the dye 1-aminobenzene-2-sulphonic acid --> 2-(21-hydroxybenzylidene-amino)- 4:6-diamino- 1 : 3 : 5-triazine is treated with formaldehyde or the coupling component is methylolated and treated with the diazo compound; (2) 2-(41-aminophenylsulphonylamino)- 4 : 6- diamino1 : 3 : 5-triazine is diazotised and coupled with 1-naphthol-3 : 5-disulphonic acid and the dyestuff treated with formaldehyde; a number of alternative coupling components are specified: (3) 1-amino-4-bromoanthraquinone-2-sulphonic acid is reacted with 2-(41-aminobenzenesulphonylamino)- 4 : 6-diamino-1 : 3 : 5-triazine and the product reacted with formaldehyde; (4) the dye 2-aminonaphthalene-6 : 8-disulphonic acid --> 2-(41-hydroxyphenylamino)-4 : 6-diamino-1 : 3 : 5-triazine is treated as in (1).
