RESIN FILM, OPTICAL RESIN FILM, LOW RETARDATION FILM, AND METHOD OF PRODUCING RESIN FILM

摘要

PROBLEM TO BE SOLVED: To provide a resin film with excellent dimensional stability before and after heating even without annealing, and an optical film with little retardation unevenness. SOLUTION: This resin film is formed by bridging at least one or more sorts of acrylic monomers by irradiation of an electron beam, of which volume shrinking ratio is 1.0% or less. It is desirable that the acrylic monomers contain at least one sort chosen from epoxy acrylate, urethane acrylate, and polyester acrylate. COPYRIGHT: (C)2009,JPO&INPIT
