Monoazo pigments of the formula WHEREIN R represents hydrogen, an alkyl or aryl group, R1 represents a hydroxynaphthalene radical in which the azo, hydroxy and carbonyl groups are in the 1,2,3-position, or the radical of the formula COCH3 ¦ --CH-- R2 represents a benzene or naphthalene radical which contains a five- or six-membered hetero ring bound by condensation, X and Y represent hydrogen, halogen, lower alkyl or alkoxy groups, and X1 and Y1 represent hydrogen, halogen, lower alkyl, alkoxy or alkoxycarbonyl groups or trifluoromethyl or cyano groups, whereby in ring A the azo and amino groups are in the m- or p-position with respect to each other are prepared. The pigments may be used for pigmenting high-molecular organic materials, such as, cellulose, ethers, polyesters, alkyd resins and polycarbonates.
