Method for manufacturing water resistant optically anisotropic film, and image display device |
摘要 |
The present invention relates to a method for manufacturing a water resistant optically anisotropic film comprising: a water resistant treatment step of bringing an optically anisotropic film containing an organic dye having an anionic group into contact with a water resistant treatment liquid containing a multivalent metal salt or a compound having two or more nitrogen atoms in a molecule thereof; and a cleaning step of cleaning the optically anisotropic film after the water resistant treatment, using a cleaning liquid containing a hydrophilic organic compound. |

1. A method for manufacturing a water resistant optically anisotropic film comprising:
bringing an optically anisotropic film containing an organic dye having an anionic group into contact with a water resistant treatment liquid containing a multivalent metal salt or a compound having two or more nitrogen atoms in a molecule thereof and cleaning the optically anisotropic film after the water resistant treatment, using a cleaning liquid consisting of water and at least one hydrophilic organic compound. |
