1. A protective film comprising:
- a cured hardcoat comprising the reaction product of a polymerizable composition comprisingone or more urethane (meth)acrylate oligomers;
at least one monomer comprising at least three (meth)acrylate groups; and
optionally inorganic nanoparticles;
wherein the cured hardcoat composition is sufficiently flexible such that a 5 micron film can be bent around a 2 mm mandrel without cracking.

Abstract
Flexible hardcoat compositions and protective films are described comprising the reaction product one or more urethane (meth)acrylate oligomers; at least one monomer comprising at least three (meth)acrylate groups; and optionally inorganic nanoparticles. The cured hardcoat composition is preferably sufficiently flexible such that a 5 micron film can be bent around a 2 mm mandrel without cracking.
