ABSTRACT:
A multi-colored display polarizer is manufactured by supporting on a transparent substrate a multi-colored polarizing film which is produced by a required number of repetitions, each using a coloring means producing a different color, a sequence of operations comprising coating a photosensitive resin onto the surface of a polarizing film blank and drying the same, exposing the coated film through a photographic negative having a desired pattern thereon to photo-set a portion of the film corresponding to the transparent portion of the negative, developing the thus exposed film, coloring the thus developed film with a suitable coloring means, and removing the photosensitive resin remaining on said photoset portion of the film.
