Abstract

PURPOSE: To provide a methyl methacrylate resin film or sheet containing C1W15 alkyl ester acrylate and ultraviolet rays absorbent which excels in the weatherability, chemical resistance, impact resistance, gloss and the like with capability of shielding ultraviolet rays and a transparency preferably.
CONSTITUTION: A methyl methacrylate resin film and sheet containing 1W15% by weight of C1W15 alkyl ester acrylate and 0.001W3.0% by weight of ultraviolet rays absorbent is produced with a capability of shielding ultraviolet rays having the following characteristics: a melt flow index (measured in accordance with ASTM: D1238-1) of 0.5W12g/10min., a shrinkage stress (in accordance with ASTM:D1504) of 5W40kg/cm2, and a biaxial shrinkage stress ratio (shrinkage stress value in the maximum level direction/shrinkage value in the minimum level direction) of 1W2.
