4'-alkoxy-2,2';6',2"-terpyridine derivatives of formula (I) and metal complexes thereof of formula (II). ##STR1## where R.sup.1 represents a substituted or unsubstituted alkyl group, wherein the substituent is a member selected from the group consisting of an aryl group, a heterocyclic group bonded to the alkyl group via the carbon atom thereof, an alkoxy group, an aryloxy group, an alkylthio group and an arylthio group; Py and Py' each represent a substituted or unsubstituted 2-pyridyl group. M(Ligl).sub.x (Lig2).sub.y (A).sub.z (II) where M is a metal ion; Ligl is the compound of formula (I): Lig2 is a ligand to the metal ion M, except Ligl; A is a counter ion to M(Ligl)x(Lig2)y; x is an integer of 1 or 2; and y and z each are an integer of from 0 to 6. The metal complexes (II) are useful as dyes having high wet heat-fastness.
