Document Type and Number:
WIPO Patent Application WO/2014/069507
Kind Code:
A1
Abstract:
[Problem] To provide an optical reflection film which highly reflects light having desired wavelengths and is reduced in haze, by controlling the level of interlaminar mingling to control the irregularities of the interface(s), even when the optical reflection film is produced by multiple coating, in particular, by simultaneous multiple coating, which attains a high production efficiency.
[Solution] An optical reflection film which comprises a base and, formed thereon, at least one unit obtained by superposing a high-refractive-index layer and a low-refractive-index layer, characterized in that the low-refractive-index layer contains silica particles onto which a silanol-modified polyvinyl alcohol has been adsorbed.
