Title:
THERMOPLASTIC RESIN COMPOSITION, OPTICAL FILM, POLARIZER PROTECTIVE FILM, POLARIZING PLATE, AND IMAGE DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP2015172112
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a thermoplastic resin composition that comprises an acrylic thermoplastic resin having a cyclic structure in the main chain and that has excellent film-forming property.SOLUTION: The thermoplastic resin composition comprises the following thermoplastic resin, and has a glass transition temperature of 115°C or higher and lower than 130°C, a melt flow rate of 7.5 to 50 [g/10 min], and a thermal decomposition start temperature of 300°C or higher. The thermoplastic resin has: a unit (A) derived from an N-substituted maleimide; a unit (B) derived from a monomer (M) that is at least one of a monomer represented by formula (2), a vinyl carboxylate, and a dialkyl maleimide and that shows, in a homopolymer state, a glass transition temperature of 20°C or lower; and a unit (C) derived from a (meth)acrylate (excluding the monomer (M)). In formula (2), Rrepresents a hydrogen atom or a methyl group; when Ris a hydrogen atom, Rrepresents a hydrocarbon group having 1 to 12 carbon atoms; and when Ris a methyl group, Rrepresents a hydrocarbon group having 4 to 12 carbon atoms.
