Abstract
1,268,699. Water soluble monoazo dyestuffs. FARBWERKE HOECHST A.G. 7 Aug., 1969 [7 Aug., 1968], No. 39556/69. Heading C4P. The invention comprises water soluble monoazo dyestuffs which in the form of the free acid correspond to the general formula wherein: B and D are a radical of the benzene or naphthalene series; A is a carboxylic acid, ester or alkyl group containing 1-4 carbon atoms; X is a direct linkage or -CH 2 -; -CH 2 CH 2 ; - NH-; or -N(alkyl)-, and n 1 and n 2 are 0, 1 or 2, n 1 +n 2 being at least 1. The dyestuffs may be prepared by comprising diazotized aromatic amines of the general formula wherein D, X, and n, are as defined above, with pyrazolone derivatives of the formula in which A, B, X and n 2 are as defined above. Alternatively, they may be obtained by converting monoazo compounds of the formula with phosphorylating agents in known manner into the corresponding phosphoric acid monoesters.
