Abstract
Dye intermediates are of formula D-R-N-CH2CH2CH2SO3M (where R is an aryl group with 1 or 2 aromatic rings, D is an H atom linked to the nuclear carbon of R in the p-position to the N atom; R1 is a residue linked by an alkyl C atom to the N atom, and M is H, Na, K or NH4). The intermediates are used to prepare water-soluble dyes of the formula A-N=N-R-N-CH2CH2CH2CH2SO3M (where A-N=N- is the coupling residue of a diazotised aromatic or heterocyclic amine or of a diazotised amino-monoazo intermediate. The alkali metal or ammonium salts of (I) have surface-active props. inaqs. soln. The dyes (II) can be used on synth. or natural polyamides and sec. cellulose acetate rayon; certain of the dyes show very good resistant to light and washing.
