Abstract

1422971 Stilbene dyes SANDOZ Ltd 13 March 1973 [17 March 1972] 11956/73 Heading C4P The invention comprises stilbene-azo and stilbene-azoxy dyestuffs containing at least one sulphonic acid group and wherein at least one cation per molecule is a tetra-(optionally substituted alkyl) ammonium cation. They are prepared by condensing a compound of the general formula wherein R is an optionally substituted alkyl group, in presence of a tetra- (optionally substituted alkyl) ammonium hydroxide to obtain the dye in salt form and then optionally reducing the nitro groups to amino groups. The tetra-alkyl ammonium cation may be partially replaced by reacting the dye with an alkali metal or ammonium salt. The dyes are used to dye paper in yellow shades.
