Abstract

1-(31 -N- trichloropyrimidylaminophenyl) -3-methyl -5-pyrazolone is prepared by condensing 1-(31-aminophenyl) -3- methyl -5- pyrazolone with tetrachloropyrimidine in a neutralised aqueous dioxan solution.ALSO:The invention comprises metal complexes of disazo dyes of formula <FORM:0955801/C3/1> wherein A is an aryl radical containing at least one sulphonic or carboxylic acid group, or a radical of formula <FORM:0955801/C3/2> B is a 1,4-arylene radical, E and E1 are radicals of coupling components each containing at least one sulphonic or carboxylic acid group and each having the <FORM:0955801/C3/3> group directly attached to an aromatic ring, n is an integer preferably of from 1 to 5 and T is a trihalogenopyrimidyl radical and wherein both the radicals represented by A and B, and/or both the radicals represented by B and E have metallizable groups in ortho position to the respective azo group. The dyes are prepared by reacting an aminodisazo dye of formula A - N = N - B - N = N - E - NHCn-1H2n-1 with a metallizing agent and an equimolecular proportion of a tetrahalopyrimidine. Specified metals are copper, nickel, cobalt and chromium. Specified tetrahalopyrimidines are tetrachloro- and tetrabromo-pyrimidine and 2,4,6-trichloro-5-bromopyrimidine. The dyes colour silk, wool, and cellulose textiles in yellow and blue shades in the presence of an acid-binding agent. In an example the disazo dye aniline-2,5-disulphonic acid --> 2-methoxy-5-methyl-aniline --> 2 - amino - 5 - naphthol - 1,7 - disulphonic acid is coppered by heating with aqueous cuprammonium sulphate solution and the copper complex condensed with tetrachloropyrimidine in a neutralized aqueous dioxan solution. Further examples and many alternative reactants are specified. Specification 902,618 is referred to.
