Problems solved by technology

When an optically anisotropic body that has discolored or is prone to discoloration is used, for example, in liquid crystal displays, etc., for purposes such as widening the viewing angle and switching polarization, there is a problem that the brightness and / or contrast of the display decreases. , or with the use of the monitor, the color of the image changes, and the quality of the monitor product is greatly reduced
[0004] Furthermore, in this field, various polymeric compounds have been reported, and an optically anisotropic body is produced using a composition containing the above polymeric compound, but the composition containing those polymeric compounds has the following problems: It is easy to generate high molecular (polymer) components, and the storage stability is not enough
When using a composition that easily generates a polymer (polymer) component, there is a high possibility that the polymer (polymer) component will increase during storage or transportation from the preparation of the composition to the process of producing the polymer
In this case, there is a problem that the viscosity and the like of the composition change, which affects optical properties such as transmittance and discoloration of the polymer obtained by using the composition.
