Claim:
1. A method for producing a thermoplastic transparent resin composition comprising a thermoplastic resin (A) and a thermoplastic resin (B) by blending the resins (A) and (B) in a ratio of mass of the resin (A) to the resin (B) of from 10/90 to 90/10: the thermoplastic resin (A) being a thermoplastic resin comprising a methyl methacrylate structural unit and a styrene structural unit, wherein the amount of the methyl methacrylate structural unit of the resin (A) is 25 to 35 mol % on the basis of the total amount of all the structural units of the resin (A); and the thermoplastic resin (B) obtained by hydrogenating 95% or more of aromatic double bonds of styrene structural unit of a thermoplastic resin which comprises a methyl methacrylate structural unit and the styrene structural unit, wherein the amount of the methyl methacrylate structural unit of the resin (B) is 55 to 73 mol % on the basis of the total amount of all the structural units of the resin (B); wherein a piece molded from the composition and having a thickness of 3.2 mm exhibits a haze of 5% or less as measured through the transmission method.
