Abstract
Mixed complexes of methine dyes of formula ##STR1## wherein M.sub.1 represents zinc, cadmium, lead or manganese, M.sub.2 represents cobalt, copper or nickel, R represents an organic radical, Z.sub.1 represents an oxygen or a sulphur atom or an imino group, X.sub.1 and Y.sub.1 represent hydrogen or halogen atoms, alkyl, alkoxy, alkoxycarbonyl, alkylsulphonyl or alkylcarbamoyl groups of 1 to 6 carbon atoms, nitro, carbamoyl or arylcarbamoyl groups, or the radicals X.sub.1 and Y.sub.1 form a fused benzene ring, X represents a hydrogen atom, Y represents a halogen atom and Z represents a nitro group or a group of formula R.sub.1 Y.sub.2 --, wherein R.sub.1 represents a hydrogen atom, an alkyl or cycloalkyl group of 1 to 6 carbon atoms, an aralkyl or aryl group, and Y.sub.2 represents an oxygen or a sulphur atom, m is 0 to 4, n is 0 to 4, p is 0 to 3, and the sum of m+n+p must be 4, and wherein the atomic ratio of M.sub.1 :M.sub.2 is between 5:95 and 95:5 which are useful for pigmenting high molecular organic material.
