Abstract:
Embodiments of the invention relate to a poly(meth)acrylimide film and a method for manufacturing such a film. At least one embodiment provides a poly(meth)acrylimide film that has (i) a total light transmittance of over 90% and (ii) haze of 2.0% or less. This film preferably has retardation of less than 50 nm. The method for manufacturing this film includes the following steps: (A) using a device provided with an extruder and a T die, a poly(meth)acrylimide molten film is continuously extruded from the T die; and (B) the poly(meth)acrylimide molten film is loaded by being fed between a rotating or circulating first mirrored-surface body and a rotating or circulating second mirrored-surface body, and then the film is pressed. During these steps, (C) the surface temperature of the first mirrored-surface body is in the range 100-200° C., and (D) the surface temperature of the second mirrored-surface body is in the range 20-200° C.
Abstract:
Embodiments of the invention provide a resin composition for optical articles, which has a blue light-blocking function, is white and transparent, and does not look yellow; and a laminate. According to at least one embodiment, the resin composition includes (A) 1 to 5 parts by mass of white inorganic microparticles and (B) 100 parts by mass of a transparent base resin. The resin composition is characterized in that (i) the white inorganic microparticles have an average particle diameter of 10 to 80 nm and (ii) the difference between the refractive index of the white inorganic microparticles and the refractive index of the base resin is 0.1 or more. According to at least one embodiment, there is provided a laminate which includes a hard coat layer or a cohesive/adhesive agent layer each made from the resin composition and a poly(meth)acrylic imide resin film layer.
