Iminoisoindolinone metal complex
Abstract
Abstract Iminoisoindolinone metal complexes of formula ##STR1## wherein A represents a 5- or 6-membered heterocyclic radical which contains at least one further heteroatom and can be fused or doubled with benzene nuclei, M represents a divalent metal atom excluding the alkaline earth metals, X represents a hydrogen atom, Y represents a halogen atom, Z represents a nitro group, an alkoxycarbonyl group of 2 to 6 carbon atoms or a group of formula RY 2 --, wherein R represents a hydrogen atom, an alkyl group of 1 to 6 carbon atoms which is substituted by an aryl radical or is unsubstituted, a cycloalkyl group of 5 to 6 carbon atoms, or represents an aryl group, and Y 2 represents an oxygen or a sulphur atom, m and n are 0 to 4, p is 0 to 2, and the sum of m+n+p must be 4, which are useful for pigmenting high molecular organic material.
