Zusammenfassung:An article includes a substrate with a surface, and a coating disposed over the surface. The coating includes a binder material and a plurality of UV scattering porous polymer particles having pores with a light scattering effective pore size of no more than 100 nm. The coating has a scattering opacity of no more than 20% in the wavelength band from 500 to 3000 nm.
