Abstract: A method of making a shaped abrasion-resistant multilayer optical film includes providing a curable composition comprising, based on the total weight of components a) to d) components: a) 87 to 96 weight percent of urethane (meth)acrylate compound having an average (meth)acrylate functionality of 2 to 4.8; b) 2 to 12.5 weight percent of (meth)acrylate monomer having a (meth)acrylate functionality of 1 to 2, wherein the (meth)acrylate monomer does not comprise a urethane (meth)acrylate compound; optionally c) 0.5 to 2 weight percent of silicone (meth)acrylate; and d) optional effective amount of photoinitiator. The curable composition is coated onto an MOF. Optionally, the curable composition to is at least partially dried. Next, the curable composition or the at least partially dried curable composition is at least partially cured to provide an abrasion-resistant multilayer optical film. Lastly, the abrasion-resistant multilayer optical film is thermoformed using a female mold having a mold surface. At least a portion of the mold surface has a radius of curvature of 58 to 76 mm and a maximum depth of 13 to 20 mm.
