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.
