Abstract:
The resin composition for an optical material according to the present invention has features that it can implement a low retardation value during the preparation of an optical film, by using a polycarbonate composition satisfying a specific condition as a retardation-adjusting agent while using polymethyl methacrylate not containing a monomer having a cyclic structure at the main chain of the polymer.

Claim (Index 1):
A resin composition for optical material, comprising\n 1) 90% to 99% by weight of polymethyl methacrylate; and 2) 1% to 10% by weight of polycarbonate, wherein the polymethyl methacrylate includes methacrylic acid monomer in an amount of 1% to 5% by weight based on the total weight of the polymethyl methacrylate, the polymethyl methacrylate has a glass transition temperature of 100\u00b0 C. or more and less than 120\u00b0 C., the polycarbonate has a glass transition temperature of 125\u00b0 C. or more and less than 135\u00b0 C. and the glass transition temperature difference between the polymethyl methacrylate and the polycarbonate is less than 20\u00b0 C.
