PURPOSE:To produce the composition excellent in release properties and useful as, e.g. a base material for an optical information recording material by adding a higher alcohol, a higher fatty acid monoglyceride and paraffin to a methyl methacrylate copolymer. CONSTITUTION:With (A) a methyl methacrylate copolymer, (B) 0.05-0.2wt.% higher alcohol, (C) 0.05-0.2wt.% fatty acid monoglyceride and (D) 0.02-0.15wt.% paraffin are admixed. The sum of the contents of the respective components (B) to (D) is controlled to 0.2-0.35wt.%. |
