At present, most ideal ultraviolet absorbers/light stabilizers are mostly compound types, especially compounded with salicylates, benzophenones, benzotriazoles, substituted acrylonitriles, triazines and hindered amines. It can achieve a more rational effect than any single ultraviolet absorber. Application areas of UV absorbers: polymers (plastics, etc.), coatings (car painting, building finishing), printing inks, post-processing of dyed/printed textiles, sunscreen cosmetics.
