Roll of optical film and process for producing polarizer using same |
| abstract |
The purpose of the present invention is to provide an optical film which rarely tears during processing even when thin. The optical-film roll is a roll obtained by winding an optical film in the direction perpendicular to the film-width direction, the optical film comprising cellulose acetate and an additive and having a thickness of 20-50 µm. The optical film has an embossed part along each width-direction end and, when a 1-kg load is imposed on a circular area with a diameter of 5 mm of the surface of the embossed parts of the optical film and the optical film in this state is held at 23ºC and 55% RH for 10 minutes, then the percentage crush represented by the following equation is 30% or higher. In the equation, D is the height of the protrusions of the embossed parts as measured after the holding and D 0 is the height of the protrusions of the embossed parts as measured before the load imposition. In the optical film, the content of residual methanol is 10-100 mass ppm of the optical film and is higher than each of the contents of residual ethanol and butanol therein. Percentage crush (%) = D/D 0 ×100 |
