Abstract
The invention comprises blue water-soluble colour salts free from sulphonic acid groups the cations of which are of formula <FORM:0995040/C4-C5/1> wherein R1 and/or R2 are hydrogen, substituted or unsubstituted alkyl, cycloalkyl, substituted or unsubstituted phenyl or benzyl radicals or from, together with the nitrogen atom, a heterocyclic ring, or in which R1 or R2, besides its connection with the nitrogen atom, is also attached to the p-position of the naphthalene ring, A1 and A2 are substituted or unsubstituted alkyl, benzyl or phenacyl radicals, and the indazole ring may be further substituted and any other alkylatable nitrogen atoms that may be present may have further positive charges. The dyes are prepared by the alkylation, cycloalkylation or aralkylation of monoazo dyes, free from sulphonic acid groups, of formula:-A-N = N-B-N(R1)R2 wherein A is a 3-indazolyl residue which may be substituted, B is a p-naphthylene radical which may be substituted and R1 and R2 are as defined above. The intermediate aminoazo dyes are prepared by the normal coupling procedures. The dyes may be used to colour mordanted cotton, leather, cellulose esters and ethers, polyamides, polyurethanes and preferably polyacrylonitrile. Examples describe the preparation of the dyes. Specification 791,932 is referred to.
