| abstract |
This invention relates to radiation-curable coating compositions comprising (a) porous silica nanoparticles having a continuous porous structure and a mean pore diameter in the range 2-50nm, wherein the pores are randomly oriented, (b) an acrylate monomer and/or an acrylate pre-polymer, and (c) a photoinitiator. This invention also relates to methods of preparing the compositions, methods of preparing coatings from the compositions, and the coatings formed from the compositions. |
