Abstract
Process for bulk dyeing high molecular organic compounds, by using anthrapyrimidines of the formula ##SPC1## As dyestuffs, wherein R denotes a hydrogen atom, an alkyl group or an aromatic radical, one X denotes an arylamino group, or a phenylthio group which is optionally substituted by 1-2 halogen atoms or alkyl groups containing 1-4 carbon atoms, and the other X denotes hydrogen atoms, and X must not be a benzophenonylamino group if R denotes a hydrogen atom.
