PHOTOPOLYMERIZABLE COMPOSITION FOR ROLL-TO-ROLL NANOIMPRINT LITHOGRAPHY AND WIRE-GRID OLARIZER FILM COMPRISING THE SAME

摘要

The present invention relates to a photopolymerizable composition for roll-to-roll nanoimprint lithography and a wire grid polarizing film comprising the same. The photopolymerizable composition for roll-to-roll nanoimprint lithography according to the present invention has excellent release properties, curing properties, etching resistance, pattern transferring properties, adherence to a substrate, chemical resistance, durability, transparency, etc., and thus can be used for manufacturing a micro-patterned film and a wire grid polarizing film using a roll-to-roll process. The photopolymerizable composition for roll-to-roll nanoimprint lithography comprises: at least one siloxane-based compound selected from the group consisting of compounds represented by chemical formula 1 and 2; and an additive comprising compounds represented by chemical formula 3 to 6. The additive constitutes 0.5 to 20 parts by weight based on the siloxane-based compound.
