PROBLEM TO BE SOLVED: To obtain a resin composition for film forming excellent in transparency, weatherability and resistance to stress-whitening, resistance to hot water- whitening or the like having excellent moldability and reduced generation of bumps by using a methacrylic resin composition blended with an acrylic multilayered polymer. SOLUTION: This methacrylic resin-blended composition comprises 50-80 pts.wt. of the mechacrylic multilayered polymer having the weight ratio of the monomer mixture of each layer is the first layer: the second layer: the third layer=5-20 wt.%: 50-80 wt.%: 15-45 wt.% (the sum is 100 wt.%) and the molecular weight of the polymer of the third layer gradually reduces from inside to outside, 50-20 pts.wt. of an acrylic copolymer comprising 85-99.5 wt.%. of methyl methacrylate and 15-0.5 wt.%. of an 1-8C alkyl acrylate.
