Title:
樹脂組成物およびフィルム
Document Type and Number:
Japanese Patent JP6731913
Kind Code:
B2
Abstract:
A resin composition according to the present invention contains an acrylic resin (A) that has a positive intrinsic birefringence and a resin (B) that has a negative intrinsic birefringence and that has a constituent unit derived from N-substituted maleimide monomers. The constituent unit derived from N-substituted maleimide monomers is contained in this resin composition at between 1% and 10% by weight. The glass-transition temperature (Tg) of this resin composition is equal to or greater than 130 ºC. While the resin composition according to the present invention exhibits excellent optical transparency, which the acrylic resin possesses, and also achieves high heat resistance, to be more specific, a high Tg, deterioration of the mechanical characteristics thereof is suppressed, which makes it possible to more reliably ensure the characteristics expected of a resin composition in which multiple types of resins are mixed, and thus, the present invention provides a resin composition that can be used for various usages including optical films.
