Abstract
The invention comprises monoazo compounds of the formula <FORM:1029212/C4-C5/1> wherein X stands for any aromatic radical which is free from azo and sulphonic acid groups R1 represents a labile atom or group which is free from sulphonic acid groups, A represents a 1:3:5-triazine or pyrimidine radical and R2 represents a labile atom or group which is free from sulphonic acid groups and which may be the same as or different from that represented by R1 or for a group containing an oxygen, sulphur or nitrogen atom through which it is connected to the triazine or pyrimidine nucleus which is free from sulphonic acid groups and which is not a labile group and the metal complexes of such of these compounds as contain a metallizable group in X in ortho position to the azo group. By a labile atom or group there is meant an atom or group which is free from sulphonic acid groups and which is bound by a covalent bond to a carbon atom of the triazine or pyrimidine nucleus but which readily dissociates under the influence of heat or alkalis, especially in the presence of moisture to form an ion or an uncharged molecule and leave a residue capable of reacting with the cellulose molecule. X may be a benzene, naphthalene or benzthiazole series radical. Such dyes are prepared by reacting appropriate diazonium compounds and coupling components or by reacting a monoazo dye corresponding to the above formula in which at least one of R1 and R2 represents a halogen atom with a tertiary amine or a compound of the formula RH or an alkali metal salt of such a compound where R represents a labile group or a group connected to the hydrogen atom by an O, S or N which is not a labile group. Metal complexes may be prepared by appropriate metallization procedures. In examples: A red dye for polyamides is obtained by diazotizing p-aminoacetanilide and coupling with 2-chloro-4 - di - (b - hydroxyethyl)amino - 6 - (41 -hydroxynaphth - 11 - yl) - 1:3:5 - triazine (1) and a grey dye for wool by chroming the dye 4-nitro-2-aminophenol with [41-chloro-61-di-(b -hydroxyethyl)aminopyrimid - 2 - yl] - 4 - naphthol. Additional examples are furnished.ALSO:4,6 - Dichloro - 2 - (41 - hydroxynaphth - 11 - yl) pyrimidine is obtained by reacting 2: 4: 6-trichloropyrimidine with 1-naphthol in the presence of aluminium chloride and benzene.
