Abstract
The present disclosure provides a photocurable coating composition, including: (a) a (meth)acrylate monomer or oligomer with at least four functional groups; (b) a difunctional (meth)acrylate monomer, (c) a monofunctional (meth)acrylate monomer, and (d) an initiator. The difunctional (meth)acrylate monomer is present in an amount of 30 to 70 wt % based on the total weight of the photocurable coating composition. The present disclosure also provides an optical film having a microstructure layer made from the photocurable coating composition. The optical film can be as a light guide film in a back light module of a display.
