| titleOfInvention | Manufacturing method of polarizer |
| abstract | The present invention relates to a method for producing a polarizer, and more particularly, a first crosslinking step of immersing a polyvinyl alcohol-based film in an aqueous solution for crosslinking containing a boron compound and a compound having two or more carboxyl groups, or a carboxyl group and an aldehyde group. A second crosslinking step immersed in an aqueous solution for crosslinking containing the compound, wherein the first crosslinking step or the second crosslinking step contains an aqueous solution for crosslinking, or acetic acid in each crosslinking solution for the first crosslinking step and the second crosslinking step. By containing zinc, it has excellent dimensional stability in the width and length direction, improves the flexibility and stretchability of the film, suppresses the occurrence of wrinkles and at the same time prevents deterioration even after standing under dry heat and excellent in color durability. It is about. |
