Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a resin composition having excellent transparency.SOLUTION: The resin composition contains an acrylic resin by 50 to 95 wt.% and a polycarbonate resin by 5 to 50 wt.%. The acrylic resin contains a copolymer obtained by polymerizing a monomer component comprising 50 to 95 wt.% of methyl methacrylate, 5 to 50 wt.% of a (meth)acrylate expressed by formula (I), and 0.1 to 20 wt.% of a monofunctional monomer other than the above compounds, and has a viscosity average molecular weight of 80000 to 300000. The polycarbonate resin has a viscosity average molecular weight of 16000 to 25000. A ratio ( A/ B) of a melt viscosity ( A) of the acrylic resin at 240°C and at a shear rate of 60 secto a melt viscosity ( B) of the polycarbonate at 240°C and at a shear rate of 60 secranges from 0.40 to 3.00. The resin composition satisfy formula (a). |
