い。Furthermore, the polarizing film produced by the above method,
The polarization properties can be further improved by dipping the dichroic dye solution into a solution containing one or more conductive polymers and a base polymer. Conventional methods for producing dye-based polarizing films can be used in methods (1) to (5) above, such as mixing one or more types of polarizing dyes in appropriate proportions as necessary, forming a film by a solution casting method, and then stretching. By combining these methods, a polarizing film using conductive polymers can be obtained. The dye to be used may be a conductive polymer or its precursor, and K may be any dye as long as it has good compatibility with the base film used and has a high dichroic ratio. Dyes, other quinophthalone dyes, perylene dyes, naphthoquinone yarn dyes, tetofuzine dyes, etc. can be used.In addition, it is possible to highly orient a conductive polymer that exhibits dichroism. When using a polarizing dye, the method for producing a polarizing film of the present invention is not necessarily limited to the above range, as long as both the conductive polymer and the dichroic dye can be highly oriented. The present invention may be a single conductive polymer film, or a film in which the conductive polymer is adsorbed, blended, or laminated and oriented with another base polymer; however, in the latter case, the base material used Examples of polymers include PVA or its derivatives, acetic acid superlose or its derivatives, and those capable of forming FfAP, such as polyetherimide, poly/L/*n, polyether-sulfone, and polycarbonate. If so, any polymer may be used without being limited to these polymers. Among them, it is preferable to use a heat-resistant film such as polyether sulfone in terms of improving the durability of the polarizing film. In the present invention, the conductive polymer film method or conductivity%! Dry method is a method for stretching a molecular precursor film or a composite film consisting of a electrocardiographic polymer and a base polymer.
The method most suitable for the film to be stretched may be used, such as axial stretching, wet-axial stretching, or low rho rolling.

る)である。The degree of polarization in the present invention refers to the degree of polarization measured by preparing two polarizing films or plates and measuring the light transmittance with the two sheets overlapped using a measuring device (Model 2 Hitachi UV-880) as follows. Here, H7 is the value measured when the two samples ρ are stacked so that the polarizing films are aligned in the same direction (this is called the parallel transmittance). 9, H, is set so that the orientation directions of the polarizing films are perpendicular to each other when the two samples are superimposed [1
This is a value measured in a state where they are aligned (called orthogonal transmittance).
