摘要： The invention is directed to a novel disazo compound represented by the formula (I) ##STR1## wherein Q is a substituted or unsubstituted phenyl or naphthyl group; Me is copper, nickel, zinc or iron; and Z is hydrogen, lower alkyl, lower alkoxyl, sulfo, or substituted or unsubstituted amino; and also to a polarizing film having said disazo compound incorporated into a polarizing film base. The polarizing film exhibits high polarizing activities comparable to those of an iodine-containing polarizing film, and also has excellent durability.
