摘要 |
The invention is directed to a novel disazo compound represented by the formula (I) <CHEM> 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.
