Title:
METHOD FOR BONDING POLYMER FILM AND METHOD FOR PRODUCING POLARIZING FILM
Document Type and Number:
WIPO Patent Application WO/2011/162110
Kind Code:
A1
Abstract:
The purpose is to achieve excellent bonding of a polymer film, such as a polyvinyl alcohol-based resin film, while controlling the use of a light absorbing agent. Provided are a method for bonding a polymer film which comprises face-contacting the surface of the polymer film with the surface of an adherend and laser welding the interface, characterized in that the laser beam is irradiated to the polymer film, which is in the water-absorbed state at least in the interface side thereof, and the thus absorbed water is allowed to absorb the laser beam to thereby achieve the laser welding, and so on.
