OPTICAL FILM HAVING COATING LAYER FOR REDUCING INTERACTIVE MOTTLE

Title:

OPTICAL FILM HAVING COATING LAYER FOR REDUCING INTERACTIVE MOTTLE

Document Type and Number:

Japanese Patent JP2003251750

Kind Code:

A

Abstract:

To provide an optical film which has a good solvent resistance and flaw resistance without an interactive mottle, and is used as a basic material for all types of optical film.

This is an optical film which has a coating layer made of a curing-type resin with a membrane thickness being 0.01 μm to 20 μm on at least one surface of a high-molecular film with a total light transmission factor being over 80%, and satisfies the following formula (a) in case the refraction factor of the coating layer is n1 and the refraction factor of the high-molecular film is n2. n2-n1≤0.02 (a) (in the said formula, the refraction factors n1, n2 are measured at 25°C using a 589-nm wavelength of sodium D-ray.
