The ultraviolet (UV) bleaching of artwork is responsible for immeasurable loss to human civilization. Existing solutions mainly reduce the exposure of artwork to light but ruin their ornamental value. Herein, we modified poly(vinyl alcohol) (PVA) using the Hantzsch reaction and used the obtained PV...
