Abstract

The UV-absorbers, UV531, UV328 and UVP were added into PU (an MDI polyurethane) to improve its light-fastness. FTIR, reflectance spectroscopy and light ageing weight loss experiments were done to test the anti-photoageing properties of the modified material. After comparative studies, it was concluded that the anti-photoageing properties of PU modified with UV531 are better than those of unmodified PU, and PU modified with UV328 and UVP. This research suggested that the modified PU with UV531 has great potential for the protection of colored lacquer relics.
