(2) the UV absorber with wide applicability, but due to its protective effects are not effectively protect the product surface and thin products, meanwhile, is a pure organic compound, there are volatile, blooming, migration, solvent extract of the shortcomings, which not only affects the persistence of its efficiency also leads to environmental pollution;

(3) excited state Quencher and hydrogen peroxide decomposers low light performance, volatile, bloom and migrating small and spare, can effectively protect the product surface and thin products. But large color depth, toxicity and pollution, high temperatures will break down discoloration, antagonism and sulfur exist;

(4) free base capture agent color shallow, and light stable effectiveness highlight, and also can effective to protection products surface and thin products, but due to has alkaline, and acid matrix, and additives exists against role, and acid environment will makes its performance by effects, meanwhile, and UV absorption agent as, due to is pure organic compounds, also exists easy volatile, and spray cream, and migration, and taking, shortcomings.
