Anti-adhesion coating composition used for hard coating and corresponding double-sided hard coating

The invention relates to an anti-adhesion coating composition used for a hard coating that is formed on a substrate surface and is characterized by wear resistance, adhesion resistance, excellent transparency, hardness and adherence with an ITO (indium tin oxide) layer. The anti-adhesion coating composition comprises, by mass, 5-40 parts of silicon oxide nanoparticles, 1-10 parts of metal oxide nanoparticles, 5-20 parts of a compound containing active polymerizable groups, 20-80 parts of a compound containing a plurality of polymerizable unsaturated groups, 0.1-10 parts of a photoinitiator and a solvent. The adding amount of the solvent can make the total mass concentration of the rest components at 0.5-80%. A prepared double-sided hard coating comprises a substrate, precoated layers disposed on two opposite surfaces of the substrate and hardened layers respectively disposed on the surfaces of the precoated layers. One of the hardened layers is formed by coating and curing of the anti-adhesion coating composition used for a hard coating. And the double-sided hard coating is mainly used in capacitive touch screens.
