<p>1. An optical film having a layer made of a transparent resin containing an anthraquinone type colorant of the formula (1) or (2) and a diimmonium type colorant of the formula (3): <CHEM> <CHEM> <CHEM> where, in the formulae (1) and (2), each of R<1> to R<15> which are independent of one another, represents a hydrogen atom, an alkyl group which may have a substituent (excluding a halogenated alkyl group), an alkoxy group, an aryloxy group, a halogen atom, an alkoxycarbonyl group, a halogenated alkyl group, an alkylthio group, an arylthio group, a cyano group, a nitro group, an amino group, an alkylamino group, an amide group, an acyloxy group, a hydroxyl group, a sulfo group or a carboxyl group. In the formula (2), R<16> represents a hydrogen atom or an alkyl group which may have a substituent. In the formula (3), each of R<17> to R<24> which are independent of one another, represents a hydrogen atom, an alkyl group which may have a substituent, an alkenyl group which may have a substituent, an aryl group which may have a substituent, or an alkynyl group which may have a substituent, and X<-> is an anion.</p> |
