Abstract

1415635 Pyrazolone monoazo dyes HOECHST AG 29 April 1974 [28 April 1973] 18731/74 Heading C4P [Also in Division Dl] Monoazo dyes have the formula in which R is straight or branched-chain alkyl carbonyl or substituted or unsubstituted aryl carbonyl having up to 20 carbon atoms, X is O or S, Y is H, Cl or Br, A is a straight or branched-chain lower alkylene group which may be substituted by MeO, EtO, or PhO or a radical R, B is H, phenyl which may be substituted by one or more substituents selected from F, Cl, Br, lower alkyl, lower alkoxy, CN and nitro groups, or a naphthyl group, and E is lower alkyl, phenyl, a carboxylic acid amide group or a carboxylic acid alkyl ester group having 2-4C. The dyes are prepared by reacting a compound where R = H with a carboxylic acid R-OH or a functional derivative thereof. They produce yellow hues on a variety of synthetic fibre materials, such as polyesters, polyamides, cellulose acetates, polyvinyl chloride, polypropylene using the Thermosol process.
