Abstract:
1. A method of subdividing a multilayer optical film body, comprising: providing a multilayer optical film body comprising at least one multilayer optical film by unwinding a roll of the multilayer optical film body; applying a first and second liner to opposed major surfaces of the multilayer optical film body wherein the first liner is applied to the multilayer optical film body electrostatically; directing laser radiation at the multilayer optical film body through the first liner, the laser radiation being adapted to produce cut lines that define a plurality of pieces of the first liner and of the multilayer optical film body; reducing the electrostatic attraction of the first liner to the multilayer optical film body; removing the plurality of pieces of the first liner from the plurality of pieces of the multilayer optical film body while the pieces of multilayer optical film body are supported by the second liner; and winding up the multilayer optical film body and the second liner into a roll.
