Abstract
Anthrapyrimidine dyes of the formula: ##SPC1## In which A is saturated alkylene of two to eight carbon atoms or cycloalkylene of six to eight carbon atoms; and ##EQU1## B is hydrogen, or IN WHICH X is saturated alkyl of one to nine carbon atoms which may bear other substituents, phenalkyl, a five-membered or six-membered heterocyclic ring, --NHR or --OR in which R is alkyl of one to six carbon atoms, cycloalkyl of six to eight carbon atoms or unsubstituted or substituted phenyl. On synthetic fibers or in thermoplastics the dyes give yellow to orange colorations which have very good fastness properties.
