Research on the Photochromic Compounds and Photochromic Coating

Photochromic coated paper was developed by using photochromic compounds coating formulation,and the optimum coating formulation was decided.The properties of light chemical mechanism of the coating layer were characterized by fluorescent spectroscopy.In the end,the light stability of the coating and the coating layer are analyzed.The results show that photochromic compounds should have the sufficient thermo-stability and weary-resistant.
