Properties of Monoazo Disperse Dyes, Derivatives of 3- and 4-Aminophthalimide

The synthesis of several disperse dyes, from 3-amino-1,2-phthalimide and its N-methyl derivative as diazo component and N,N-dialkylanilines as coupling component is described. The dyeing behaviour and some physical properties of these dyes are investigated and compared with those of isomeric dyes containing azo groups in the 4-position, previously studied
