Method for producing a single protective polarizing film with a transparent resin layer, a method for producing a polarizing film with an adhesive layer, and a method for producing an optical laminate

摘要

The present invention is a method of manufacturing a single protective polarizing film having a protective film only on one side of the polarizer and a single protective polarizing film with a transparent resin layer having a transparent resin layer provided on the other side of the polarizer of the single protective polarizing film, wherein the polarizer is poly The process of applying a coating liquid containing a resin component or a curable component capable of constituting a transparent resin layer to the polarizer and solidifying the obtained coating film in the transparent resin layer, which contains a vinyl alcohol-based resin and has a thickness of 10 μm or less. Or formed by a process of curing, and in the coating process of the coating solution, the polarizer has an uncoated portion not applied with the coating solution in an area of less than 20 mm from both ends in the width direction to the inside, or the It is characterized in that the coating liquid is applied over the entire width direction of the polarizer. According to the production method of the present invention, the occurrence of curl of the piece protective polarizing film with a transparent resin layer can be suppressed.
