Abstract
A methacrylic resin comprising 80 to 98.5 wt % of methyl methacrylate monomer unit and 1.5 to 20 wt % of at least one different vinyl monomer unit copolymerizable with methyl methacrylate, characterized in that the methacrylic resin has a weight average molecular weight measured by gel permeation chromatography (GPC) of 60,000 to 230,000 and comprises 7 to 30% of a component having a weight average molecular weight of ⅕ or less of a peak weight average molecular weight (Mp) obtained from a GPC elution curve based on the methacrylic resin component.
