Abstract
The invention relates to a process for preparing alkoxy-substituted, metal-containing phthalocyanines of the formula (I) where R is substituted or unsubstituted alkyl or cycloalkyl, M is a divalent metal atom, metaloxy or a trivalent or tetravalent substituted metal atom, characterized in that the phthalonitrile of the formula (II) is reacted in the presence of a metal salt and a base in a water-miscible solvent.
