Abstract

1416837 Pyrazolone monoazo dyestuffs HOECHST AG 26 April 1974 [28 April 1973] 18388/74 Heading C4P Monoazo dyes have the formula in which A is straight or branched chain lower alkylene, X is O to S, Y is lower alkym or -COO- lower alkyl, R is H, Cl or lower alkyl, and R 1 is H, Cl, Br or lower alkyl. The term "lower" denotes groups having 1-4 carbon atoms. A preferred structure is The dyes may be applied from aqueous dispersion or from organic solvents and give yellow dyeings or prints with, e.g. cellulose esters, polyesters or polyamides.
