Abstract:
1. A scratch-resistant optical film comprising a reflective substrate, wherein at least one of the surfaces of the substrate has a scratch-resistant layer which possesses anti-static properties, wherein the reflective substrate is a plastic substrate, the scratch-resistant layer has convex-concave structures and is formed by coating a hard coat solution on the substrate followed by a heat and ultraviolet (UV) dual curing, and the scratch-resistant layer has a surface resistivity in the range from 10 8 to 10 12 Ω/□, and a pencil hardness of 3H or more as measured according to JIS K5400 standard method; wherein the substrate is a monolayer or multilayer structure and contains organic particles selected from the group consisting of (meth)acrylate resin, urethane resin, silicone resin, and mixtures thereof, and the hard coat solution comprises an anti-static agent, a UV curing resin, and at least one resin selected from the group consisting of a thermal setting resin, a thermal plastic resin, and a mixture thereof.
