Abstract

A resin composite, a method of producing the resin composite, a molded product, a film, and an article excellent in impact resistance are provided. The resin composite contains a methacrylic resin (A), which contains no less than 80% by mass of a structural unit derived from methyl methacrylate and has a melt viscosity η(A) of 1500 to 3500 Pa·s at 220° C. and a shear rate of 122/sec, and a triblock copolymer (B), which has a methacrylic acid ester polymer block (b2) coupled to each of two ends of an acrylic acid ester polymer block (b1), at a specific ratio. The triblock copolymer (B) includes the block (b1) and the block (b2) at a specific ratio and has a melt viscosity η(B) of 75 to 1500 Pa·s at 220° C. and a shear rate of 122/sec. The ratio of η(A)/η(B) is from 1 to 20.
