Color filter having polarizability.

摘要

The present invention relates to a color filter having polarizability, which comprises; a dye having a spectral transmissibility; a dichroic dye having a polarizability corresponding to the former dye; and a base resin. The filter can be produced by coating and fixing the former dye on a monochromatic polarizing film produced by using the dichroic dye; mixing the former dye, the dichroic dye and the base resin, melting and extruding the mixture to produce a film and monoaxially stretching the film; dyeing a transparent film with the former dye and the dichroic dye and then monoaxially stretching the dyed film; or dyeing a transparent monoaxially stretched film with the former dye and the dichroic dye.
