Description

PVB, for example, tends to have high transparency and high compatibility with organic solvents. In addition, PVB has high weather resistance and high light resistance, and because the light-absorbing composition contains PVB, the light-absorbing film and optical filter obtained from the light-absorbing composition tend to exhibit high weather resistance and light resistance. Furthermore, PVB can exhibit advantageous properties as a binder for functional components such as the above-mentioned ultraviolet-absorbing compounds.
