PURPOSE: A deformable film using radiation-curing coating is provided to ensure excellent chemical resistance, abrasion resistance and scratch resistance, transparency of a film, and blocking resistance. CONSTITUTION: A deformable film comprises a radiation-curing coating. The radiation-curing coating includes a polyurethane polymer containing a (meth)acrylate group and further inorganic nanoparticles with an average particle size of 1-200 nm. The polyurethane polymer can be obtained from the reaction of a reaction mixture. The reaction mixture comprises polyisocyanate and a compound which has a (meth)acrylate group and is reactive to isocyanate.
