Abstract
A graft copolymer contains crosslinked (meth)acrylic polymer particles (a) having an average particle size of 150 nm or less and a glass transition temperature of −10° C. or lower and a non-crosslinked methacrylic polymer component (b) having a weight-average molecular weight of 25×10or more. At least a part of the non-crosslinked polymer component (b) is grafted to the crosslinked polymer particles (a). The crosslinked polymer particles (a) account for 1 to less than 50 wt % of the total weight of the crosslinked polymer particles (a) and the non-crosslinked polymer component (b).
