Abstract: A dichroic dye can be blended with a non-dichroic dye (melanin and melanin derivatives) and still maintain a commercially acceptable level of polarizing efficiency. Efficient polarizers exhibit polarizing efficiencies of greater or equal to 95% and the best are even greater than or equal to 98%. Since melanin has unique features with respect to absorption of wavelengths of light, melanin is very useful to have in combination with a polarizer that takes advantage of this absorption. The blending can be done by a mixture (preferably an aqueous mixture) of melanin and a dichroic dye in a ratio sufficient to achieve the desired color and polarizing effect.
