ABSTRACT:
A process for preparing a hydrophilic polymer film comprising coating a photopolymerization solution which comprises a hydrophilic monomer of lower water swelling ability and a UV stabilizer, on the film surface pre-treated with high frequency, and photopolymerizing the solution so as to improve the hydrophilic property, climate-resistability, and blocking property of the polymer film.
