Abstract
Methods and compositions for forming polarizing images on an oriented substrate with specially formulated inks are disclosed. The inks can contain a dichroic dye, water, and a humectant. 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.
