摘要：PURPOSE:To prevent the overlapping of colors and spacing between colors by printing a required pattern on the surface of a polarizing elementary film, coloring the unprinted part with polarizing ink, eluting the printed ink and coating the colored polarizing film with ink. CONSTITUTION:A required pattern is printed out on the film surface of a polarizing film 1 obtained by rolling a film composed of macromolecular elementary materials such as polyvinyl alcohol by using a printing press or a photogravure press and types suitable for the press. Since pattern parts other than the stated pattern is printed with ink, the polarizing film 1 corresponding to the stated pattern remains as it is. If the polarizing film is colored with polarizing ink, the 1st colored polarizing film 5 with the stated pattern and color is formed. On the other hand, the covered polarizing elementary film is exposed by washing the printed ink with a solvent. Then a required pattern is printed again on the exposed polarizing elementary film and the colored polarizing film is printed through ink. Hereafter, the above-mentioned operation is repeated. Thus, the overlapping of colors of colored polarizing films and space between these colors can be prevented.
