Optical film and method for manufacturing optical film

A method for manufacturing an optical film including a base material, and a hardcoat layer, in which a pencil hardness measured according to JIS K 5600-5-4:1999 is 2H or higher, the number of times of folding endurance measured by an MIT tester according to JIS P 8115:2001 is 1000 or more, and

• wherein the reflection characteristics measured using a three-dimensional gonio-spectrophotometric color measurement system is that;
• in a case where an incident ray is made incident on the optical film from −60° with respect to a normal direction of the optical film, an angle width within which 10% of outgoing ray peak intensity is obtained is 6° or less, and an intensity of an outgoing ray at 50° from the normal direction is 1% or less of the outgoing ray peak intensity, the method comprising:
• (i-1) applying a hardcoat layer forming composition to the base material to provide a coating film;
• and
• (iii-1) curing the coating film while bringing the coating film into contact with one smooth metal roll.

• (i-2) applying a hardcoat layer forming composition to the base material to provide a coating film;
• (ii-2) curing the coating film;
• and
• (iii-2) performing a calender treatment.
