<p>A methacrylic resin, including 80 to 99.5 % by mass of a methacrylic acid ester monomer unit, and 0.5 to 20 % by mass of other vinyl monomer unit which is copolymerizable with at least one of the methacrylic acid ester, wherein the methacrylic resin satisfies the following conditions (I) to (III):
(I) having a weight average molecular weight measured by gel permeation chromatography (GPC) of 60,000 to 300,000;
(II) having a content of a molecular weight component 1/5 or less the peak molecular weight (Mp) obtained from a GPC elution curve, said content being 7 to 40% based on a region area ratio obtained from the GPC elution curve; and
(III) having an angle of repose of 20 to 40°.</p> |
