ABSTRACT:
The formation of polarizing images can be improved by the use of specially formulated inks. The inks can contain a de-salted dichroic dye, de-ionized water, and a polyhydric alcohol. The dichroic inks are particularly advantageous when printed on specially coated molecularly oriented sheets through the technology of ink jet printing. The ink molecules align themselves parallel to the oriented molecules of the oriented sheet thereby forming a light-polarizing image.
