ANTIREFLECTION FILM, MANUFACTURING METHOD THEREOF, POLARIZING PLATE AND IMAGE DISPLAY DEVICE USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an antireflection film excellent in scratch-resistance while achieving both storage stability and curing activity of a coating solution; and further to provide a polarizing plate and an image display device using the antireflection film.

SOLUTION: The antireflection film comprises a support and at least one layer formed on the support by applying a composition containing at least one salt formed from an acid and an organic base whose conjugate acid has a pKa of a specific range or a nitrogen-containing organic base having a boiling point of a specific range and the antireflection film has a haze value due to surface scattering of 1% or more and less than 10%. A method for manufacturing the antireflection film comprises: a process of applying a composition for forming a low refractive index layer; then thermally curing the coated composition for a specific time under the condition of specific temperature; and further a process of curing the coated composition by use of an active energy ray. A polarizing plate characterized in that the antireflection film is used for a protective film thereof and an image display device characterized in that the antireflection film or the polarizing plate is used for the outermost surface of the display, are also provided.
