Abstract
PURPOSE: To increase the absorption 2 color ratio of a polymide-dye base polarizing film by dyeing and orienting dyes only one side of an oriented nylon 12 film.
CONSTITUTION: Dyes such as direct fast yellow GC are dyed at 70 to 100°C on a nylon-12 film in which lauryl lactam is polymerized before it is oriented more than 4 times preferably 6 or more times at 70 to 150°C in at least one direction or after it has been oriented. This polarizing film has high polarizing ability and yet superior moisture resistance, etc
