FILM BODY HAVING FINE RUGGED STRUCTURE ON SURFACE, STRUCTURE HAVING THE FILM BODY ON SURFACE, AND POLYMERIZABLE COMPOSITION FOR FORMING THE FILM BODY

摘要

PROBLEM TO BE SOLVED: To provide a film body having a fine rugged structure on a surface thereof, which has antireflection property and light-transmitting property as well as favorable scratch resistance and substrate adhesion property, a structure having the film body, and a polymerizable composition to be used for forming the film body.SOLUTION: A film body (2) having a fine rugged structure (1) on a surface thereof, which can reduce reflection, comprises a polymerizable composition that is polymerized by irradiation of active energy rays. The polymerizable composition contains a polyfunctional (meth)acrylate and a polyfunctional urethane (meth)acrylate each having an alkylene glycol chain. The polymerizable composition has a crosslinking density of 3.30×10mol/cmor more and 5.70×10mol/cmor less.
