Provided is a thermoplastic resin film having at least one of film surfaces being excellent in printability, having sufficiently low internal haze, and exhibiting a favorable matte appearance. A thermoplastic resin film according to the present invention composed of a thermoplastic resin composition (C) including at least one kind of a thermoplastic resin (R) and fine particles (P) having a volume average particle diameter of 0.5 to 15 &#x3bc;m and a refractive index different from that of the thermoplastic resin (R) by 0.02 or more. At least one of film surfaces satisfies formulas (1) and (2).&#x2265;60&#x2003;&#x2003;(1),&#x2212;35&#x2264;&#x2212;10&#x2003;&#x2003;(2)(In the formulas (1) and (2), Gis 60&#xb0; gloss (%) at 20&#xb0; C., Gis 60&#xb0; gloss (%) when the thermoplastic resin film is heated at a temperature 10&#xb0; C. higher than a glass transition temperature of the thermoplastic resin composition (C) for 30 minutes, then cooled to 20&#xb0; C.).

Thermoplastic resin film, its manufacturing method, and laminated body

A film obtained by molding a methacrylic resin composition, the methacrylic resin composition comprises: a methacrylic resin having a triad syndiotacticity (rr) of not less than 50% and a weight average molecular weight of 80000 to 200000 and comprising not less than 92% by mass of a structural unit derived from methyl methacrylate, and a polycarbonate resin having a melt volume-flow rate of 130 to 250 cm/20 min at 300&#xb0; C. and 1.2 Kg, in which a mass ratio of the methacrylic resin to the polycarbonate resin is 91/9 to 99/1, and the total content of the methacrylic resin and the polycarbonate resin is 80 to 100% by mass. The film is layered to at least one surface of a polarizer to give a polarizing plate.

Film

Provided is a thermoplastic acrylic resin composition comprising a methacrylic resin (A) and a polyvinyl acetal resin (B) obtained by acetalizing a polyvinyl alcohol resin with an aldehyde having 4 or more carbon atoms and an aldehyde having 3 or less carbon atoms in which the total amount of the vinyl alcohol units acetalized with the aldehyde having 4 or more carbon atoms and the aldehyde having 3 or less carbon atoms is 65 to 85 mol % of all repeating units, and the molar ratio of the vinyl alcohol unit acetalized with the aldehyde having 4 or more carbon atoms to the vinyl alcohol unit acetalized with the aldehyde having 3 or less carbon atoms is from 90/10 to 0/100. Furthermore, provided are an article molded from the thermoplastic acrylic resin composition and a method of producing the thermoplastic acrylic resin composition comprising the steps of mixing a methacrylic resin (A) and a polyvinyl acetal resin (B), increasing the resin temperature to 160&#xb0; C. or more, and then decreasing the resin temperature to 120&#xb0; C. or less.
